+# CW20 Basic
+
+This is a basic implementation of a cw20 contract. It implements
+the [CW20 spec](../../packages/cw20/README.md) and is designed to
+be deployed as is, or imported into other contracts to easily build
+cw20-compatible tokens with custom logic.
+
+Implements:
+
+- [x] CW20 Base
+- [x] Mintable extension
+- [x] Allowances extension
+
+## Running this contract
+
+You will need Rust 1.44.1+ with `wasm32-unknown-unknown` target installed.
+
+You can run unit tests on this via: 
+
+`cargo test`
+
+Once you are happy with the content, you can compile it to wasm via:
+
+```
+RUSTFLAGS='-C link-arg=-s' cargo wasm
+cp ../../target/wasm32-unknown-unknown/release/cw20_base.wasm .
+ls -l cw20_base.wasm
+sha256sum cw20_base.wasm
+```
+
+Or for a production-ready (optimized) build, run a build command in the
+the repository root: https://github.com/CosmWasm/cw-plus#compiling.
+
+## Importing this contract
+
+You can also import much of the logic of this contract to build another
+ERC20-contract, such as a bonding curve, overiding or extending what you
+need.
+
+Basically, you just need to write your handle function and import 
+`cw20_base::contract::handle_transfer`, etc and dispatch to them.
+This allows you to use custom `ExecuteMsg` and `QueryMsg` with your additional
+calls, but then use the underlying implementation for the standard cw20
+messages you want to support. The same with `QueryMsg`. You *could* reuse `instantiate`
+as it, but it is likely you will want to change it. And it is rather simple.
+
+Look at [`cw20-staking`](https://github.com/CosmWasm/cw-tokens/tree/main/contracts/cw20-staking) for an example of how to "inherit"
+all this token functionality and combine it with custom logic.

+# CW4 Stake
+
+This is a second implementation of the [cw4 spec](../../packages/cw4/README.md).
+It fulfills all elements of the spec, including the raw query lookups,
+and is designed to be used as a backing storage for 
+[cw3 compliant contracts](../../packages/cw3/README.md).
+
+It provides a similar API to [`cw4-group`] (which handles elected membership),
+but rather than appointing members (by admin or multisig), their
+membership and weight are based on the number of tokens they have staked.
+This is similar to many DAOs.
+
+Only one denom can be bonded with both `min_bond` as the minimum amount
+that must be sent by one address to enter, as well as `tokens_per_weight`,
+which can be used to normalize the weight (eg. if the token is uatom
+and you want 1 weight per ATOM, you can set `tokens_per_weight = 1_000_000`).
+
+There is also an unbonding period (`Duration`) which sets how long the
+tokens are frozen before being released. These frozen tokens can neither
+be used for voting, nor claimed by the original owner. Only after the period
+can you get your tokens back. This liquidity loss is the "skin in the game"
+provided by staking to this contract.
+
+## Instantiation
+
+**TODO**
+
+To create it, you must pass in a list of members, as well as an optional
+`admin`, if you wish it to be mutable.
+
+```rust
+pub struct InstantiateMsg {
+    /// denom of the token to stake
+    pub stake: String,
+    pub tokens_per_weight: u64,
+    pub min_bond: Uint128,
+    pub unbonding_period: Duration,
+}
+```
+
+Members are defined by an address and a weight. This is transformed
+and stored under their `CanonicalAddr`, in a format defined in
+[cw4 raw queries](../../packages/cw4/README.md#raw).
+
+Note that 0 *is an allowed weight*. This doesn't give any voting rights, 
+but it does define this address is part of the group, which may be
+meaningful in some circumstances.
+
+The weights of the members will be computed as the funds they send 
+(in tokens) divided by `tokens_per_weight`, rounded down to the nearest
+whole number (i.e. using integer division). If the total sent is less than
+`min_bond`, the stake will remain, but they will not be counted as a
+member. If `min_bond` is higher than `tokens_per_weight`, you cannot
+have any member with 0 weight.
+
+## Messages
+
+Most messages and queries are defined by the 
+[cw4 spec](../../packages/cw4/README.md). Please refer to it for more info.
+
+The following messages have been added to handle un/staking tokens:
+
+`Bond{}` - bond all staking tokens sent with the message and update membership weight
+
+`Unbond{tokens}` - starts the unbonding process for the given number 
+  of tokens. The sender immediately loses weight from these tokens,
+  and can claim them back to his wallet after `unbonding_period`
+
+`Claim{}` -  used to claim your native tokens that you previously "unbonded"
+  after the contract-defined waiting period (eg. 1 week)
+
+And the corresponding queries:
+
+`Claims{address}` - Claims shows the tokens in process of unbonding
+    for this address
+
+`Staked{address}` - Show the number of tokens currently staked by this address.

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or

+# An ERC20 token contract
+
+This is an implementation of Ethereum's [ERC20](https://eips.ethereum.org/EIPS/eip-20) interface.
+Please note that ERC20 has some fundamental flaws, many of which have been resolved with [ERC777](https://eips.ethereum.org/EIPS/eip-777).
+This projects intents to serve as a simple example that token developers can familiarize with easily, not as a modern token contract.

+# Developing
+
+If you have recently created a contract with this template, you probably could use some
+help on how to build and test the contract, as well as prepare it for production. This
+file attempts to provide a brief overview, assuming you have installed a recent
+version of Rust already (eg. 1.44.1+).
+
+## Prerequisites
+
+Before starting, make sure you have [rustup](https://rustup.rs/) along with a
+recent `rustc` and `cargo` version installed. Currently, we are testing on 1.44.1+.
+
+And you need to have the `wasm32-unknown-unknown` target installed as well.
+
+You can check that via:
+
+```sh
+rustc --version
+cargo --version
+rustup target list --installed
+# if wasm32 is not listed above, run this
+rustup target add wasm32-unknown-unknown
+```
+
+## Compiling and running tests
+
+Now that you created your custom contract, make sure you can compile and run it before
+making any changes. Go into the
+
+```sh
+# this will produce a wasm build in ./target/wasm32-unknown-unknown/release/YOUR_NAME_HERE.wasm
+cargo wasm
+
+# this runs unit tests with helpful backtraces
+RUST_BACKTRACE=1 cargo unit-test
+
+# this runs integration tests with cranelift backend (uses rust stable)
+cargo integration-test
+
+# this runs integration tests with singlepass backend (needs rust nightly)
+cargo integration-test --no-default-features --features singlepass
+
+# auto-generate json schema
+cargo schema
+```
+
+The wasmer engine, embedded in `cosmwasm-vm` supports multiple backends:
+singlepass and cranelift. Singlepass has fast compile times and slower run times,
+and supportes gas metering. It also requires rust `nightly`. This is used as default
+when embedding `cosmwasm-vm` in `go-cosmwasm` and is needed to use if you want to
+check the gas usage.
+
+However, when just building contacts, if you don't want to worry about installing
+two rust toolchains, you can run all tests with cranelift. The integration tests
+may take a small bit longer, but the results will be the same. The only difference
+is that you can not check gas usage here, so if you wish to optimize gas, you must
+switch to nightly and run with cranelift.
+
+### Understanding the tests
+
+The main code is in `src/contract.rs` and the unit tests there run in pure rust,
+which makes them very quick to execute and give nice output on failures, especially
+if you do `RUST_BACKTRACE=1 cargo unit-test`.
+
+However, we don't just want to test the logic rust, but also the compiled Wasm artifact
+inside a VM. You can look in `tests/integration.rs` to see some examples there. They
+load the Wasm binary into the vm and call the contract externally. Effort has been
+made that the syntax is very similar to the calls in the native rust contract and
+quite easy to code. In fact, usually you can just copy a few unit tests and modify
+a few lines to make an integration test (this should get even easier in a future release).
+
+To run the latest integration tests, you need to explicitely rebuild the Wasm file with
+`cargo wasm` and then run `cargo integration-test`.
+
+We consider testing critical for anything on a blockchain, and recommend to always keep
+the tests up to date. While doing active development, it is often simplest to disable
+the integration tests completely and iterate rapidly on the code in `contract.rs`,
+both the logic and the tests. Once the code is finalized, you can copy over some unit
+tests into the integration.rs and make the needed changes. This ensures the compiled
+Wasm also behaves as desired in the real system.
+
+## Generating JSON Schema
+
+While the Wasm calls (`init`, `handle`, `query`) accept JSON, this is not enough
+information to use it. We need to expose the schema for the expected messages to the
+clients. You can generate this schema by calling `cargo schema`, which will output
+4 files in `./schema`, corresponding to the 3 message types the contract accepts,
+as well as the internal `State`.
+
+These files are in standard json-schema format, which should be usable by various
+client side tools, either to auto-generate codecs, or just to validate incoming
+json wrt. the defined schema.
+
+## Preparing the Wasm bytecode for production
+
+Before we upload it to a chain, we need to ensure the smallest output size possible,
+as this will be included in the body of a transaction. We also want to have a
+reproducible build process, so third parties can verify that the uploaded Wasm
+code did indeed come from the claimed rust code.
+
+To solve both these issues, we have produced `rust-optimizer`, a docker image to
+produce an extremely small build output in a consistent manner. The suggest way
+to run it is this:
+
+```sh
+docker run --rm -v "$(pwd)":/code \
+  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
+  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
+  cosmwasm/rust-optimizer:0.10.4
+```
+
+We must mount the contract code to `/code`. You can use a absolute path instead
+of `$(pwd)` if you don't want to `cd` to the directory first. The other two
+volumes are nice for speedup. Mounting `/code/target` in particular is useful
+to avoid docker overwriting your local dev files with root permissions.
+Note the `/code/target` cache is unique for each contract being compiled to limit
+interference, while the registry cache is global.
+
+This is rather slow compared to local compilations, especially the first compile
+of a given contract. The use of the two volume caches is very useful to speed up
+following compiles of the same contract.
+
+This produces a `contract.wasm` file in the current directory (which must be the root
+directory of your rust project, the one with `Cargo.toml` inside). As well as
+`hash.txt` containing the Sha256 hash of `contract.wasm`, and it will rebuild
+your schema files as well.
+
+### Testing production build
+
+Once we have this compressed `contract.wasm`, we may want to ensure it is actually
+doing everything it is supposed to (as it is about 4% of the original size).
+If you update the "WASM" line in `tests/integration.rs`, it will run the integration
+steps on the optimized build, not just the normal build. I have never seen a different
+behavior, but it is nice to verify sometimes.
+
+```rust
+static WASM: &[u8] = include_bytes!("../contract.wasm");
+```
+
+Note that this is the same (deterministic) code you will be uploading to
+a blockchain to test it out, as we need to shrink the size and produce a
+clear mapping from wasm hash back to the source code.

+# Importing
+
+In [Publishing](./Publishing.md), we discussed how you can publish your contract to the world.
+This looks at the flip-side, how can you use someone else's contract (which is the same
+question as how they will use your contract). Let's go through the various stages.
+
+## Getting the Code
+
+Before using remote code, you most certainly want to verify it is honest.
+There are two ways to get the code of another contract, either by cloning the git repo
+or by downloading the cargo crate. You should be familiar with using git already.
+However, the rust publishing system doesn't rely on git tags (they are optional),
+so to make sure you are looking at the proper code, I would suggest getting the
+actual code of the tagged crate.
+
+```sh
+cargo install cargo-download
+cargo download cw-escrow==0.1.0 > crate.tar.gz
+tar xzvf crate.tar.gz
+cd cw-escrow-0.1.0
+```
+
+(alternate, simpler approach, but seems to be broken):
+
+```sh
+cargo install cargo-clone
+cargo clone cw-escrow --vers 0.1.0
+```
+
+## Verifying Artifacts
+
+The simplest audit of the repo is to simply check that the artifacts in the repo
+are correct. You can use the same commands you do when developing, with the one
+exception that the `.cargo/config` file is not present on downloaded crates,
+so you will have to run the full commands.
+
+First, make a git commit here, so we can quickly see any diffs:
+
+```sh
+git init .
+echo target > .gitignore
+git add .
+git commit -m 'From crates.io'
+```
+
+To validate the tests:
+
+```sh
+cargo build --release --target wasm32-unknown-unknown
+cargo test
+```
+
+To generate the schema:
+
+```sh
+cargo run --example schema
+```
+
+And to generate the `contract.wasm` and `hash.txt`:
+
+```sh
+docker run --rm -v "$(pwd)":/code \
+  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
+  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
+  cosmwasm/rust-optimizer:0.9.0
+```
+
+Make sure the values you generate match what was uploaded with a simple `git diff`.
+If there is any discrepancy, please raise an issue on the repo, and please add an issue
+to the cawesome-wasm list if the package is listed there (it should be validated before
+adding, but just in case).
+
+In the future, we will produce a script to do this automatic verification steps that can
+be run by many individuals to quickly catch any fake uploaded wasm hashes in a
+decentralized manner.
+
+## Reviewing
+
+Once you have done the quick programatic checks, it is good to give at least a quick
+look through the code. A glance at `examples/schema.rs` to make sure it is outputing
+all relevant structs from `contract.rs`, and also ensure `src/lib.rs` is just the
+default wrapper (nothing funny going on there). After this point, we can dive into
+the contract code itself. Check the flows for the handle methods, any invariants and
+permission checks that should be there, and a reasonable data storage format.
+
+You can dig into the contract as far as you want, but it is important to make sure there
+are no obvious backdoors at least.
+
+## Decentralized Verification
+
+It's not very practical to do a deep code review on every dependency you want to use,
+which is a big reason for the popularity of code audits in the blockchain world. We trust
+some experts review in lieu of doing the work ourselves. But wouldn't it be nice to do this
+in a decentralized manner and peer-review each other's contracts? Bringing in deeper domain
+knowledge and saving fees.
+
+Luckily, there is an amazing project called [crev](https://github.com/crev-dev/cargo-crev/blob/master/cargo-crev/README.md)
+that provides `A cryptographically verifiable code review system for the cargo (Rust) package manager`.
+
+I highly recommend that CosmWasm contract developers get set up with this. At minimum, we
+can all add a review on a package that programmatically checked out that the json schemas
+and wasm bytecode do match the code, and publish our claim, so we don't all rely on some
+central server to say it validated this. As we go on, we can add deeper reviews on standard
+packages.
+
+If you want to use `cargo-crev`, please follow their
+[getting started guide](https://github.com/crev-dev/cargo-crev/blob/master/cargo-crev/src/doc/getting_started.md)
+and once you have made your own *proof repository* with at least one *trust proof*,
+please make a PR to the [`cawesome-wasm`]() repo with a link to your repo and
+some public name or pseudonym that people know you by. This allows people who trust you
+to also reuse your proofs.
+
+There is a [standard list of proof repos](https://github.com/crev-dev/cargo-crev/wiki/List-of-Proof-Repositories)
+with some strong rust developers in there. This may cover dependencies like `serde` and `snafu`
+but will not hit any CosmWasm-related modules, so we look to bootstrap a very focused
+review community.

+# Publishing Contracts
+
+This is an overview of how to publish the contract's source code in this repo.
+We use Cargo's default registry [crates.io](https://crates.io/) for publishing contracts written in Rust.
+
+## Preparation
+
+Ensure the `Cargo.toml` file in the repo is properly configured. In particular, you want to
+choose a name starting with `cw-`, which will help a lot finding CosmWasm contracts when
+searching on crates.io. For the first publication, you will probably want version `0.1.0`.
+If you have tested this on a public net already and/or had an audit on the code,
+you can start with `1.0.0`, but that should imply some level of stability and confidence.
+You will want entries like the following in `Cargo.toml`:
+
+```toml
+name = "cw-escrow"
+version = "0.1.0"
+description = "Simple CosmWasm contract for an escrow with arbiter and timeout"
+repository = "https://github.com/CosmWasm/cosmwasm-examples"
+```
+
+You will also want to add a valid [SPDX license statement](https://spdx.org/licenses/),
+so others know the rules for using this crate. You can use any license you wish,
+even a commercial license, but we recommend choosing one of the following, unless you have
+specific requirements.
+
+* Permissive: [`Apache-2.0`](https://spdx.org/licenses/Apache-2.0.html#licenseText) or [`MIT`](https://spdx.org/licenses/MIT.html#licenseText)
+* Copyleft: [`GPL-3.0-or-later`](https://spdx.org/licenses/GPL-3.0-or-later.html#licenseText) or [`AGPL-3.0-or-later`](https://spdx.org/licenses/AGPL-3.0-or-later.html#licenseText)
+* Commercial license: `Commercial` (not sure if this works, I cannot find examples)
+
+It is also helpful to download the LICENSE text (linked to above) and store this
+in a LICENSE file in your repo. Now, you have properly configured your crate for use
+in a larger ecosystem.
+
+### Updating schema
+
+To allow easy use of the contract, we can publish the schema (`schema/*.json`) together
+with the source code.
+
+```sh
+cargo schema
+```
+
+Ensure you check in all the schema files, and make a git commit with the final state.
+This commit will be published and should be tagged. Generally, you will want to
+tag with the version (eg. `v0.1.0`), but in the `cosmwasm-examples` repo, we have
+multiple contracts and label it like `escrow-0.1.0`. Don't forget a
+`git push && git push --tags`
+
+### Note on build results
+
+Build results like Wasm bytecode or the expected hash don't need to be committed, since
+they don't belong to the source publication.
+An optimized build will be automatically done on release tags by the CI build, and its
+results will attached to the release.
+
+A single source code can be built with multiple different optimizers, so
+we should not make any strict assumptions on the tooling that will be used.
+
+## Publishing
+
+Now that your package is properly configured and all artifacts are committed, it
+is time to share it with the world.
+Please refer to the [complete instructions for any questions](https://rurust.github.io/cargo-docs-ru/crates-io.html),
+but I will try to give a quick overview of the happy path here.
+
+### Registry
+
+You will need an account on [crates.io](https://crates.io) to publish a rust crate.
+If you don't have one already, just click on "Log in with GitHub" in the top-right
+to quickly set up a free account. Once inside, click on your username (top-right),
+then "Account Settings". On the bottom, there is a section called "API Access".
+If you don't have this set up already, create a new token and use `cargo login`
+to set it up. This will now authenticate you with the `cargo` cli tool and allow
+you to publish.
+
+### Uploading
+
+Once this is set up, make sure you commit the current state you want to publish.
+Then try `cargo publish --dry-run`. If that works well, review the files that
+will be published via `cargo package --list`. If you are satisfied, you can now
+officially publish it via `cargo publish`.
+
+Congratulations, your package is public to the world.
+
+### Sharing
+
+Once you have published your package, people can now find it by
+[searching for "cw-" on crates.io](https://crates.io/search?q=cw).
+But that isn't exactly the simplest way. To make things easier and help
+keep the ecosystem together, we suggest making a PR to add your package
+to the [`cawesome-wasm`](https://github.com/cosmwasm/cawesome-wasm) list.
+
+### Organizations
+
+Many times you are writing a contract not as a solo developer, but rather as
+part of an organization. You will want to allow colleagues to upload new
+versions of the contract to crates.io when you are on holiday.
+[These instructions show how]() you can set up your crate to allow multiple maintainers.
+
+You can add another owner to the crate by specifying their github user. Note, you will
+now both have complete control of the crate, and they can remove you:
+
+`cargo owner --add ethanfrey`
+
+You can also add an existing github team inside your organization:
+
+`cargo owner --add github:confio:developers`
+
+The team will allow anyone who is currently in the team to publish new versions of the crate.
+And this is automatically updated when you make changes on github. However, it will not allow
+anyone in the team to add or remove other owners.

+# Escrow
+
+This is a simple single-use escrow contract. It creates a contract that can hold some
+native tokens and gives the power to an arbiter to release them to a pre-defined
+beneficiary. They can release all tokens, or only a fraction. If an optional
+timeout is reached, the tokens can no longer be released, rather they can only
+be returned to the original funder. Tokens can be added to the contract at any
+time without causing any errors, or losing access to them.
+
+This contract is mainly considered as a simple tutorial example. In the real
+world, you would probably want one contract to manage many escrows and allow
+some global configuration options on it. It is generally simpler to rely on
+some well-known address for handling all escrows securely than checking each
+deployed escrow is using the proper wasm code.
+
+As of v0.2.0, this was rebuilt from
+[`cosmwasm-template`](https://github.com/confio/cosmwasm-template),
+which is the recommended way to create any contracts.
+
+## Using this project
+
+If you want to get acquainted more with this contract, you should check out
+[Developing](./Developing.md), which explains more on how to run tests and develop code.
+[Publishing](./Publishing.md) contains useful information on how to publish your contract
+to the world, once you are ready to deploy it on a running blockchain. And
+[Importing](./Importing.md) contains information about pulling in other contracts or crates
+that have been published.
+
+But more than anything, there is an [online tutorial](https://www.cosmwasm.com/docs/getting-started/intro),
+which leads you step-by-step on how to modify this particular contract.

+//! This integration test tries to run and call the generated wasm.
+//! It depends on a Wasm build being available, which you can create with `cargo wasm`.
+//! Then running `cargo integration-test` will validate we can properly call into that generated Wasm.
+//!
+//! You can easily convert unit tests to integration tests as follows:
+//! 1. Copy them over verbatim
+//! 2. Then change
+//!      let mut deps = mock_dependencies(20, &[]);
+//!    to
+//!      let mut deps = mock_instance(WASM, &[]);
+//! 3. If you access raw storage, where ever you see something like:
+//!      deps.storage.get(CONFIG_KEY).expect("no data stored");
+//!    replace it with:
+//!      deps.with_storage(|store| {
+//!          let data = store.get(CONFIG_KEY).expect("no data stored");
+//!          //...
+//!      });
+//! 4. Anywhere you see query(&deps, ...) you must replace it with query(&mut deps, ...)

+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier

+# An ERC20 token contract
+
+This is an implementation of Ethereum's [ERC20](https://eips.ethereum.org/EIPS/eip-20) interface.
+Please note that ERC20 has some fundamental flaws, many of which have been resolved with [ERC777](https://eips.ethereum.org/EIPS/eip-777).
+This projects intents to serve as a simple example that token developers can familiarize with easily, not as a modern token contract.

+// `Any` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;
+//     Any any;
+//     any.PackFrom(foo);
+//     ...
+//     if (any.UnpackTo(&foo)) {
+//       ...
+//     }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+//     Foo foo = ...;
+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {
+//       foo = any.unpack(Foo.class);
+//     }
+//
+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):
+//       any.Unpack(foo)
+//       ...
+//
+//  Example 4: Pack and unpack a message in Go
+//
+//      foo := &pb.Foo{...}
+//      any, err := ptypes.MarshalAny(foo)
+//      ...
+//      foo := &pb.Foo{}
+//      if err := ptypes.UnmarshalAny(any, foo); err != nil {
+//        ...
+//      }
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;
+//     }
+//
+//     {
+//       "@type": "type.googleapis.com/google.profile.Person",
+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"
+//     }
+//
+message Any {
+  // A URL/resource name that uniquely identifies the type of the serialized
+  // protocol buffer message. This string must contain at least
+  // one "/" character. The last segment of the URL's path must represent
+  // the fully qualified name of the type (as in
+  // `path/google.protobuf.Duration`). The name should be in a canonical form
+  // (e.g., leading "." is not accepted).
+  //
+  // In practice, teams usually precompile into the binary all types that they
+  // expect it to use in the context of Any. However, for URLs which use the
+  // scheme `http`, `https`, or no scheme, one can optionally set up a type
+  // server that maps type URLs to message definitions as follows:
+  //
+  // * If no scheme is provided, `https` is assumed.
+  // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+  //   value in binary format, or produce an error.
+  // * Applications are allowed to cache lookup results based on the
+  //   URL, or have them precompiled into a binary to avoid any
+  //   lookup. Therefore, binary compatibility needs to be preserved
+  //   on changes to types. (Use versioned type names to manage
+  //   breaking changes.)
+  //
+  // Note: this functionality is not currently available in the official
+  // protobuf release, and it is not used for type URLs beginning with
+  // type.googleapis.com.
+  //
+  // Schemes other than `http`, `https` (or the empty scheme) might be
+  // used with implementation specific semantics.
+  //
+  string type_url = 1;
+

+// 1. Sender chain is acting as the source zone. The coins are transferred
+// to an escrow address (i.e locked) on the sender chain and then transferred
+// to the receiving chain through IBC TAO logic. It is expected that the
+// receiving chain will mint vouchers to the receiving address.
+//
+// 2. Sender chain is acting as the sink zone. The coins (vouchers) are burned
+// on the sender chain and then transferred to the receiving chain though IBC
+// TAO logic. It is expected that the receiving chain, which had previously
+// sent the original denomination, will unescrow the fungible token and send
+// it to the receiving address.
+//
+// Another way of thinking of source and sink zones is through the token's
+// timeline. Each send to any chain other than the one it was previously
+// received from is a movement forwards in the token's timeline. This causes
+// trace to be added to the token's history and the destination port and
+// destination channel to be prefixed to the denomination. In these instances
+// the sender chain is acting as the source zone. When the token is sent back
+// to the chain it previously received from, the prefix is removed. This is
+// a backwards movement in the token's timeline and the sender chain
+// is acting as the sink zone.
+//
+// Example:
+// These steps of transfer occur: A -> B -> C -> A -> C -> B -> A
+//
+// 1. A -> B : sender chain is source zone. Denom upon receiving: 'B/denom'
+// 2. B -> C : sender chain is source zone. Denom upon receiving: 'C/B/denom'
+// 3. C -> A : sender chain is source zone. Denom upon receiving: 'A/C/B/denom'
+// 4. A -> C : sender chain is sink zone. Denom upon receiving: 'C/B/denom'

+
+# Concepts
+
+## Client State
+
+The `ClientState` for a solo machine light client stores the latest sequence, the frozen sequence,
+the latest consensus state, and client flag indicating if the client should be allowed to be updated
+after a governance proposal. 
+
+If the client is not frozen then the frozen sequence is 0. 
+
+## Consensus State
+
+The consensus states stores the public key, diversifier, and timestamp of the solo machine light client. 
+
+The diversifier is used to prevent accidental misbehaviour if the same public key is used across
+different chains with the same client identifier. It should be unique to the chain the light client
+is used on. 
+
+## Public Key
+
+The public key can be a single public key or a multi-signature public key. The public key type used
+must fulfill the tendermint public key interface (this will become the SDK public key interface in the
+near future). The public key must be registered on the application codec otherwise encoding/decoding 
+errors will arise. The public key stored in the consensus state is represented as a protobuf `Any`. 
+This allows for flexibility in what other public key types can be supported in the future. 
+ 
+## Counterparty Verification
+
+The solo machine light client can verify counterparty client state, consensus state, connection state,
+channel state, packet commitments, packet acknowledgements, packet receipt absence, 
+and the next sequence receive. At the end of each successful verification call the light
+client sequence number will be incremented. 
+
+Successful verification requires the current public key to sign over the proof.
+
+## Proofs
+
+A solo machine proof should verify that the solomachine public key signed
+over some specified data. The format for generating marshaled proofs for
+the SDK's implementation of solo machine is as follows:
+
+1. Construct the data using the associated protobuf definition and marshal it.
+
+For example:
+
+```go
+data := &ClientStateData{
+  Path:        []byte(path.String()),
+  ClientState: any,
+}
+
+dataBz, err := cdc.Marshal(data)
+```
+
+The helper functions `...DataBytes()` in [proof.go](../types/proof.go) handle this
+functionality. 
+
+2. Construct the `SignBytes` and marshal it.
+
+For example:
+
+```go
+signBytes := &SignBytes{
+  Sequence:    sequence,
+  Timestamp:   timestamp,
+  Diversifier: diversifier,
+  DataType:    CLIENT,
+  Data:        dataBz,
+}
+
+signBz, err := cdc.Marshal(signBytes)
+```
+
+The helper functions `...SignBytes()` in [proof.go](../types/proof.go) handle this functionality.
+The `DataType` field is used to disambiguate what type of data was signed to prevent potential 
+proto encoding overlap.
+
+3. Sign the sign bytes. Embed the signatures into either `SingleSignatureData` or `MultiSignatureData`.
+Convert the `SignatureData` to proto and marshal it.
+
+For example:
+
+```go
+sig, err := key.Sign(signBz)
+sigData := &signing.SingleSignatureData{
+  Signature: sig,
+}
+
+protoSigData := signing.SignatureDataToProto(sigData)
+bz, err := cdc.Marshal(protoSigData)
+```
+
+4. Construct a `TimestampedSignatureData` and marshal it. The marshaled result can be passed in 
+as the proof parameter to the verification functions.
+
+For example:
+
+```go
+timestampedSignatureData := &types.TimestampedSignatureData{
+  SignatureData: sigData,
+  Timestamp: solomachine.Time,
+}
+
+proof, err := cdc.Marshal(timestampedSignatureData)
+```
+
+NOTE: At the end of this process, the sequence associated with the key needs to be updated. 
+The sequence must be incremented each time proof is generated. 
+
+## Updates By Header
+
+An update by a header will only succeed if:
+
+- the header provided is parseable to solo machine header
+- the header sequence matches the current sequence
+- the header timestamp is greater than or equal to the consensus state timestamp
+- the currently registered public key generated the proof
+
+If the update is successful:
+
+- the public key is updated
+- the diversifier is updated
+- the timestamp is updated
+- the sequence is incremented by 1
+- the new consensus state is set in the client state 
+
+## Updates By Proposal
+
+An update by a governance proposal will only succeed if:
+
+- the substitute provided is parseable to solo machine client state
+- the `AllowUpdateAfterProposal` client parameter is set to `true`
+- the new consensus state public key does not equal the current consensus state public key
+
+If the update is successful:
+
+- the subject client state is updated to the substitute client state
+- the subject consensus state is updated to the substitute consensus state
+- the client is unfrozen (if it was previously frozen)
+
+## Misbehaviour
+
+Misbehaviour handling will only succeed if:
+
+- the misbehaviour provided is parseable to solo machine misbehaviour
+- the client is not already frozen
+- the current public key signed over two unique data messages at the same sequence and diversifier. 
+
+If the misbehaviour is successfully processed:
+
+- the client is frozen by setting the frozen sequence to the misbehaviour sequence
+
+NOTE: Misbehaviour processing is data processing order dependent. A misbehaving solo machine
+could update to a new public key to prevent being frozen before misbehaviour is submitted. 
+
+## Upgrades
+
+Upgrades to solo machine light clients are not supported since an entirely different type of 
+public key can be set using normal client updates.

+## Abstract
+
+This paper defines the implementation of the ICS06 protocol on the Cosmos SDK. For the general
+specification please refer to the [ICS06 Specification](https://github.com/cosmos/ibc/tree/master/spec/client/ics-006-solo-machine-client).
+
+This implementation of a solo machine light client supports single and multi-signature public
+keys. The client is capable of handling public key updates by header and governance proposals.
+The light client is capable of processing client misbehaviour. Proofs of the counterparty state
+are generated by the solo machine client by signing over the desired state with a certain sequence,
+diversifier, and timestamp.

+/*
+This file contains the logic for storage and iteration over `IterationKey` metadata that is stored
+for each consensus state. The consensus state key specified in ICS-24 and expected by counterparty chains
+stores the consensus state under the key: `consensusStates/{revision_number}-{revision_height}`, with each number
+represented as a string.
+While this works fine for IBC proof verification, it makes efficient iteration difficult since the lexicographic order
+of the consensus state keys do not match the height order of consensus states. This makes consensus state pruning and
+monotonic time enforcement difficult since it is inefficient to find the earliest consensus state or to find the neigboring
+consensus states given a consensus state height.
+Changing the ICS-24 representation will be a major breaking change that requires counterparty chains to accept a new key format.
+Thus to avoid breaking IBC, we can store a lookup from a more efficiently formatted key: `iterationKey` to the consensus state key which
+stores the underlying consensus state. This efficient iteration key will be formatted like so: `iterateConsensusStates{BigEndianRevisionBytes}{BigEndianHeightBytes}`.
+This ensures that the lexicographic order of iteration keys match the height order of the consensus states. Thus, we can use the SDK store's
+Iterators to iterate over the consensus states in ascending/descending order by providing a mapping from `iterationKey -> consensusStateKey -> ConsensusState`.
+A future version of IBC may choose to replace the ICS24 ConsensusState path with the more efficient format and make this indirection unnecessary.

+// Pruning:
+// UpdateClient will additionally retrieve the earliest consensus state for this clientID and check if it is expired. If it is,

+# Changelog
+
+## 0.5.2
+
+**2020-11-10**
+
+### Improvements
+
+- [\#134](https://github.com/tendermint/tm-db/pull/134) Improve GoLevelDB iterator performance by bounding underlying iterator range (@klim0v)
+
+## 0.5.1
+
+**2020-03-30**
+
+### Bug Fixes
+
+- [boltdb] [\#81](https://github.com/tendermint/tm-db/pull/81) Use correct import path go.etcd.io/bbolt
+
+## 0.5.0
+
+**2020-03-11**
+
+### Breaking Changes
+
+- [\#71](https://github.com/tendermint/tm-db/pull/71) Closed or written batches can no longer be reused, all non-`Close()` calls will panic
+
+- [memdb] [\#74](https://github.com/tendermint/tm-db/pull/74) `Iterator()` and `ReverseIterator()` now take out database read locks for the duration of the iteration
+
+- [memdb] [\#56](https://github.com/tendermint/tm-db/pull/56) Removed some exported methods that were mainly meant for internal use: `Mutex()`, `SetNoLock()`, `SetNoLockSync()`, `DeleteNoLock()`, and `DeleteNoLockSync()`
+
+### Improvements
+
+- [memdb] [\#53](https://github.com/tendermint/tm-db/pull/53) Use a B-tree for storage, which significantly improves range scan performance
+
+- [memdb] [\#56](https://github.com/tendermint/tm-db/pull/56) Use an RWMutex for improved performance with highly concurrent read-heavy workloads
+
+### Bug Fixes
+
+- [boltdb] [\#69](https://github.com/tendermint/tm-db/pull/69) Properly handle blank keys in iterators
+
+- [cleveldb] [\#65](https://github.com/tendermint/tm-db/pull/65) Fix handling of empty keys as iterator endpoints
+
+## 0.4.1
+
+**2020-2-26**

+## 0.4
+
+**2020-1-7**
+
+### BREAKING CHANGES
+
+- [\#30](https://github.com/tendermint/tm-db/pull/30) Interface Breaking, Interfaces return errors instead of panic:
+  - Changes to function signatures:
+    - DB interface:
+      - `Get([]byte) ([]byte, error)`
+      - `Has(key []byte) (bool, error)`
+      - `Set([]byte, []byte) error`
+      - `SetSync([]byte, []byte) error`
+      - `Delete([]byte) error`
+      - `DeleteSync([]byte) error`
+      - `Iterator(start, end []byte) (Iterator, error)`
+      - `ReverseIterator(start, end []byte) (Iterator, error)`
+      - `Close() error`
+      - `Print() error`
+    - Batch interface:
+      - `Write() error`
+      - `WriteSync() error`
+    - Iterator interface:
+      - `Error() error`

+# Tendermint DB
+
+![Test](https://github.com/tendermint/tm-db/workflows/Test/badge.svg?branch=master)
+![Lint](https://github.com/tendermint/tm-db/workflows/Lint/badge.svg?branch=master)
+[![](https://godoc.org/github.com/tendermint/tm-db?status.svg)](http://godoc.org/github.com/tendermint/tm-db)
+
+Common database interface for various database backends. Primarily meant for applications built on [Tendermint](https://github.com/tendermint/tendermint), such as the [Cosmos SDK](https://github.com/cosmos/cosmos-sdk), but can be used independently of these as well.
+
+### Minimum Go Version
+
+Go 1.13+
+
+## Supported Database Backends
+
+- **[GoLevelDB](https://github.com/syndtr/goleveldb) [stable]**: A pure Go implementation of [LevelDB](https://github.com/google/leveldb) (see below). Currently the default on-disk database used in the Cosmos SDK.
+
+- **MemDB [stable]:** An in-memory database using [Google's B-tree package](https://github.com/google/btree). Has very high performance both for reads, writes, and range scans, but is not durable and will lose all data on process exit. Does not support transactions. Suitable for e.g. caches, working sets, and tests. Used for [IAVL](https://github.com/tendermint/iavl) working sets when the pruning strategy allows it.
+
+- **[LevelDB](https://github.com/google/leveldb) [experimental]:** A [Go wrapper](https://github.com/jmhodges/levigo) around [LevelDB](https://github.com/google/leveldb). Uses LSM-trees for on-disk storage, which have good performance for write-heavy workloads, particularly on spinning disks, but requires periodic compaction to maintain decent read performance and reclaim disk space. Does not support transactions.
+
+- **[BoltDB](https://github.com/etcd-io/bbolt) [experimental]:** A [fork](https://github.com/etcd-io/bbolt) of [BoltDB](https://github.com/boltdb/bolt). Uses B+trees for on-disk storage, which have good performance for read-heavy workloads and range scans. Supports serializable ACID transactions.
+
+- **[RocksDB](https://github.com/tecbot/gorocksdb) [experimental]:** A [Go wrapper](https://github.com/tecbot/gorocksdb) around [RocksDB](https://rocksdb.org). Similarly to LevelDB (above) it uses LSM-trees for on-disk storage, but is optimized for fast storage media such as SSDs and memory. Supports atomic transactions, but not full ACID transactions.
+
+## Meta-databases
+
+- **PrefixDB [stable]:** A database which wraps another database and uses a static prefix for all keys. This allows multiple logical databases to be stored in a common underlying databases by using different namespaces. Used by the Cosmos SDK to give different modules their own namespaced database in a single application database.
+
+- **RemoteDB [experimental]:** A database that connects to distributed Tendermint db instances via [gRPC](https://grpc.io/). This can help with detaching difficult deployments such as LevelDB, and can also ease dependency management for Tendermint developers.
+
+## Tests
+
+To test common databases, run `make test`. If all databases are available on the local machine, use `make test-all` to test them all.

+remotedb is a package for connecting to distributed Tendermint db.DB
+instances. The purpose is to detach difficult deployments such as
+CLevelDB that requires gcc or perhaps for databases that require
+custom configurations such as extra disk space. It also eases
+the burden and cost of deployment of dependencies for databases
+to be used by Tendermint developers. Most importantly it is built
+over the high performant gRPC transport.
+
+remotedb's RemoteDB implements db.DB so can be used normally
+like other databases. One just has to explicitly connect to the
+remote database with a client setup such as:
+
+	client, err := remotedb.NewRemoteDB(addr, cert)
+	// Make sure to invoke InitRemote!
+	if err := client.InitRemote(&remotedb.Init{Name: "test-remote-db", Type: "leveldb"}); err != nil {
+	    log.Fatalf("Failed to initialize the remote db")
+	}
+
+	client.Set(key1, value)
+	gv1 := client.SetSync(k2, v2)
+
+	client.Delete(k1)
+	gv2 := client.Get(k1)
+
+	for itr := client.Iterator(k1, k9); itr.Valid(); itr.Next() {
+	    ik, iv := itr.Key(), itr.Value()
+	    ds, de := itr.Domain()
+	}
+
+	stats := client.Stats()
+
+	if !client.Has(dk1) {
+	      client.SetSync(dk1, dv1)

+// `google.api.http` annotation on the RPC method,
+// see "google/api/annotations.proto" for details.
+//
+// The mapping consists of a field specifying the path template and

+// operation on a resource collection of messages:
+//
+//
+//     service Messaging {
+//       rpc GetMessage(GetMessageRequest) returns (Message) {

+//       SubMessage sub = 2;    // `sub.subfield` is url-mapped
+//     }
+//     message Message {
+//       string text = 1; // content of the resource
+//     }
+//
+// The same http annotation can alternatively be expressed inside the
+// `GRPC API Configuration` YAML file.
+//
+//     http:
+//       rules:
+//         - selector: <proto_package_name>.Messaging.GetMessage
+//           get: /v1/messages/{message_id}/{sub.subfield}
+//
+// This definition enables an automatic, bidrectional mapping of HTTP
+// JSON to RPC. Example:
+//
+// HTTP | RPC
+// -----|-----
+// `GET /v1/messages/123456/foo`  | `GetMessage(message_id: "123456" sub: SubMessage(subfield: "foo"))`
+//
+// In general, not only fields but also field paths can be referenced
+// from a path pattern. Fields mapped to the path pattern cannot be
+// repeated and must have a primitive (non-message) type.
+//
+// Any fields in the request message which are not bound by the path
+// pattern automatically become (optional) HTTP query
+// parameters. Assume the following definition of the request message:
+//
+//
+//     service Messaging {
+//       rpc GetMessage(GetMessageRequest) returns (Message) {
+//         option (google.api.http).get = "/v1/messages/{message_id}";
+//       }
+//     }
+//     message GetMessageRequest {
+//       message SubMessage {
+//         string subfield = 1;
+//       }
+//       string message_id = 1; // mapped to the URL
+//       int64 revision = 2;    // becomes a parameter
+//       SubMessage sub = 3;    // `sub.subfield` becomes a parameter
+//     }
+//
+//
+// This enables a HTTP JSON to RPC mapping as below:
+//
+// HTTP | RPC
+// -----|-----
+// `GET /v1/messages/123456?revision=2&sub.subfield=foo` | `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo"))`
+//
+// Note that fields which are mapped to HTTP parameters must have a
+// primitive type or a repeated primitive type. Message types are not
+// allowed. In the case of a repeated type, the parameter can be
+// repeated in the URL, as in `...?param=A&param=B`.
+//
+// For HTTP method kinds which allow a request body, the `body` field
+// specifies the mapping. Consider a REST update method on the
+// message resource collection:
+//
+//
+//     service Messaging {
+//       rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+//         option (google.api.http) = {
+//           put: "/v1/messages/{message_id}"
+//           body: "message"
+//         };
+//       }
+//     }
+//     message UpdateMessageRequest {
+//       string message_id = 1; // mapped to the URL
+//       Message message = 2;   // mapped to the body
+//     }
+//
+//
+// The following HTTP JSON to RPC mapping is enabled, where the
+// representation of the JSON in the request body is determined by
+// protos JSON encoding:
+//
+// HTTP | RPC
+// -----|-----
+// `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" message { text: "Hi!" })`
+//
+// The special name `*` can be used in the body mapping to define that
+// every field not bound by the path template should be mapped to the
+// request body.  This enables the following alternative definition of
+// the update method:
+//
+//     service Messaging {
+//       rpc UpdateMessage(Message) returns (Message) {
+//         option (google.api.http) = {
+//           put: "/v1/messages/{message_id}"
+//           body: "*"
+//         };
+//       }
+//     }
+//     message Message {
+//       string message_id = 1;
+//       string text = 2;
+//     }
+//
+//
+// The following HTTP JSON to RPC mapping is enabled:
+//
+// HTTP | RPC
+// -----|-----
+// `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" text: "Hi!")`
+//
+// Note that when using `*` in the body mapping, it is not possible to
+// have HTTP parameters, as all fields not bound by the path end in
+// the body. This makes this option more rarely used in practice of
+// defining REST APIs. The common usage of `*` is in custom methods
+// which don't use the URL at all for transferring data.
+//
+// It is possible to define multiple HTTP methods for one RPC by using
+// the `additional_bindings` option. Example:
+//
+//     service Messaging {
+//       rpc GetMessage(GetMessageRequest) returns (Message) {
+//         option (google.api.http) = {
+//           get: "/v1/messages/{message_id}"
+//           additional_bindings {
+//             get: "/v1/users/{user_id}/messages/{message_id}"
+//           }
+//         };
+//       }
+//     }
+//     message GetMessageRequest {
+//       string message_id = 1;
+//       string user_id = 2;
+//     }
+//
+//
+// This enables the following two alternative HTTP JSON to RPC
+// mappings:
+//
+// HTTP | RPC
+// -----|-----
+// `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+// `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "123456")`
+//
+// # Rules for HTTP mapping
+//
+// The rules for mapping HTTP path, query parameters, and body fields
+// to the request message are as follows:
+//
+// 1. The `body` field specifies either `*` or a field path, or is
+//    omitted. If omitted, it indicates there is no HTTP request body.
+// 2. Leaf fields (recursive expansion of nested messages in the
+//    request) can be classified into three types:
+//     (a) Matched in the URL template.
+//     (b) Covered by body (if body is `*`, everything except (a) fields;

+// Protobuf library provides support to pack/unpack Any values in the form

+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;

+//     }

+//     Foo foo = ...;
+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {
+//       foo = any.unpack(Foo.class);
+//     }
+//
+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):
+//       any.Unpack(foo)
+//       ...
+//
+//  Example 4: Pack and unpack a message in Go
+//
+//      foo := &pb.Foo{...}
+//      any, err := ptypes.MarshalAny(foo)
+//      ...
+//      foo := &pb.Foo{}
+//      if err := ptypes.UnmarshalAny(any, foo); err != nil {
+//        ...
+//      }
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;
+//     }
+//
+//     {
+//       "@type": "type.googleapis.com/google.profile.Person",
+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"
+//     }
+//
+message Any {
+  // A URL/resource name that uniquely identifies the type of the serialized
+  // protocol buffer message. This string must contain at least
+  // one "/" character. The last segment of the URL's path must represent
+  // the fully qualified name of the type (as in
+  // `path/google.protobuf.Duration`). The name should be in a canonical form
+  // (e.g., leading "." is not accepted).
+  //
+  // In practice, teams usually precompile into the binary all types that they
+  // expect it to use in the context of Any. However, for URLs which use the
+  // scheme `http`, `https`, or no scheme, one can optionally set up a type
+  // server that maps type URLs to message definitions as follows:
+  //
+  // * If no scheme is provided, `https` is assumed.
+  // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+  //   value in binary format, or produce an error.
+  // * Applications are allowed to cache lookup results based on the
+  //   URL, or have them precompiled into a binary to avoid any
+  //   lookup. Therefore, binary compatibility needs to be preserved
+  //   on changes to types. (Use versioned type names to manage
+  //   breaking changes.)
+  //
+  // Note: this functionality is not currently available in the official
+  // protobuf release, and it is not used for type URLs beginning with
+  // type.googleapis.com.
+  //
+  // Schemes other than `http`, `https` (or the empty scheme) might be
+  // used with implementation specific semantics.

+# Governance
+
+This document gives an overview of how the various governance
+proposals interact with the CosmWasm contract lifecycle. It is
+a high-level, technical introduction meant to provide context before
+looking into the code, or constructing proposals. 
+
+## Proposal Types
+We have added 9 new wasm specific proposal types that cover the contract's live cycle and authorization:
+ 
+* `StoreCodeProposal` - upload a wasm binary
+* `InstantiateContractProposal` - instantiate a wasm contract
+* `MigrateContractProposal` - migrate a wasm contract to a new code version
+* `SudoContractProposal` - call into the protected `sudo` entry point of a contract
+* `ExecuteContractProposal` - execute a wasm contract as an arbitrary user
+* `UpdateAdminProposal` - set a new admin for a contract
+* `ClearAdminProposal` - clear admin for a contract to prevent further migrations
+* `PinCodes` - pin the given code ids in cache. This trades memory for reduced startup time and lowers gas cost
+* `UnpinCodes` - unpin the given code ids from the cache. This frees up memory and returns to standard speed and gas cost
+* `UpdateInstantiateConfigProposal` - update instantiate permissions to a list of given code ids. 
+
+For details see the proposal type [implementation](https://github.com/okex/exchain/blob/master/x/wasm/types/proposal.go)

+### Unit tests
+[Proposal type validations](https://github.com/okex/exchain/blob/master/x/wasm/types/proposal_test.go)
+
+## Proposal Handler
+The [wasmd proposal_handler](https://github.com/okex/exchain/blob/master/x/wasm/keeper/proposal_handler.go) implements the `gov.Handler` function
+and executes the wasmd proposal types after a successful tally.
+ 
+The proposal handler uses a [`GovAuthorizationPolicy`](https://github.com/okex/exchain/blob/master/x/wasm/keeper/authz_policy.go#L29) to bypass the existing contract's authorization policy.
+
+### Tests
+* [Integration: Submit and execute proposal](https://github.com/okex/exchain/blob/master/x/wasm/keeper/proposal_integration_test.go)
+
+## Gov Integration
+The wasmd proposal handler can be added to the gov router in the [abci app](https://github.com/okex/exchain/blob/master/app/app.go#L306)
+to receive proposal execution calls. 
+```go
+govRouter.AddRoute(wasm.RouterKey, wasm.NewWasmProposalHandler(app.wasmKeeper, enabledProposals))
+```
+
+## Wasmd Authorization Settings
+
+Settings via sdk `params` module: 
+- `code_upload_access` - who can upload a wasm binary: `Nobody`, `Everybody`, `OnlyAddress`
+- `instantiate_default_permission` - platform default, who can instantiate a wasm binary when the code owner has not set it 
+
+See [params.go](https://github.com/okex/exchain/blob/master/x/wasm/types/params.go)
+
+### Init Params Via Genesis 
+
+```json
+    "wasm": {
+      "params": {
+        "code_upload_access": {
+          "permission": "Everybody"
+        },
+        "instantiate_default_permission": "Everybody"
+      }
+    },  
+```
+
+The values can be updated via gov proposal implemented in the `params` module.
+
+### Update Params Via [ParamChangeProposal](https://github.com/okex/exchain/libs/cosmos-sdk/blob/v0.45.3/proto/cosmos/params/v1beta1/params.proto#L10)
+Example to submit a parameter change gov proposal:
+```sh
+wasmd tx gov submit-proposal param-change <proposal-json-file> --from validator --chain-id=testing -b block
+```

+# IBC specification
+
+This documents how CosmWasm contracts are expected to interact with IBC.
+
+## General Concepts
+
+**IBC Enabled** - when instantiating a contract, we detect if it supports IBC messages.
+  We require "feature flags" in the contract/vm handshake to ensure compatibility
+  for features like staking or chain-specific extensions. IBC functionality will require
+  another "feature flag", and the list of "enabled features" can be returned to the `x/wasm`
+  module to control conditional IBC behavior.
+  
+  If this feature is enabled, it is considered "IBC Enabled", and that info will
+  be stored in the ContractInfo. (For mock, we assume all contracts are IBC enabled)
+  
+Also, please read the [IBC Docs](https://docs.cosmos.network/master/ibc/overview.html)
+for detailed descriptions of the terms *Port*, *Client*, *Connection*,
+and *Channel*
+  
+## Overview
+
+We use "One Port per Contract", which is the most straight-forward mapping, treating each contract 
+like a module. It does lead to very long portIDs however. Pay special attention to both the Channel establishment 
+(which should be compatible with standard ICS20 modules without changes on their part), as well
+as how contracts can properly identify their counterparty.
+
+(We considered on port for the `x/wasm` module and multiplexing on it, but [dismissed that idea](#rejected-ideas))
+
+* Upon `Instantiate`, if a contract is *IBC Enabled*, we dynamically 
+  bind a port for this contract. The port name is `wasm.<contract address>`,
+  eg. `wasm.cosmos1hmdudppzceg27qsuq707tjg8rkgj7g5hnvnw29`
+* If a *Channel* is being established with a registered `wasm.xyz` port,
+  the `x/wasm.Keeper` will handle this and call into the appropriate
+  contract to determine supported protocol versions during the
+  [`ChanOpenTry` and `ChanOpenAck` phases](https://docs.cosmos.network/master/ibc/overview.html#channels).
+  (See [Channel Handshake Version Negotiation](https://docs.cosmos.network/master/ibc/custom.html#channel-handshake-version-negotiation))
+* Both the *Port* and the *Channel* are fully owned by one contract.
+* `x/wasm` will allow both *ORDERED* and *UNORDERED* channels and pass that mode
+  down to the contract in `OnChanOpenTry`, so the contract can decide if it accepts
+  the mode. We will recommend the contract developers stick with *ORDERED* channels
+  for custom protocols unless they can reason about async packet timing.
+* When sending a packet, the CosmWasm contract must specify the local *ChannelID*.
+  As there is a unique *PortID* per contract, that is filled in by `x/wasm`
+  to produce the globally unique `(PortID, ChannelID)`
+* When receiving a Packet (or Ack or Timeout), the contracts receives the local
+  *ChannelID* it came from, as well as the packet that was sent by the counterparty.
+* When receiving an Ack or Timeout packet, the contract also receives the
+  original packet that it sent earlier.
+* We do not support multihop packets in this model (they are rejected by `x/wasm`).
+  They are currently not fully specified nor implemented in IBC 1.0, so let us
+  simplify our model until this is well established
+
+## Workflow
+
+Establishing *Clients* and *Connections* is out of the scope of this
+module and must be created by the same means as for `ibc-transfer`
+(via the [go cli](https://github.com/okex/exchain/libs/relayer) or better [ts-relayer](https://github.com/confio/ts-relayer)).
+`x/wasm` will bind a unique *Port* for each "IBC Enabled" contract.
+
+For mocks, all the Packet Handling and Channel Lifecycle Hooks are routed 
+to some Golang stub handler, but containing the contract address, so we
+can perform contract-specific actions for each packet. In a real setting,
+we route to the contract that owns the port/channel and call one of it's various
+entry points.
+
+Please refer to the CosmWasm repo for all 
+[details on the  IBC API from the point of view of a CosmWasm contract](https://github.com/CosmWasm/cosmwasm/blob/main/IBC.md).
+
+## Future Ideas
+
+Here are some ideas we may add in the future
+
+### Dynamic Ports and Channels
+
+* multiple ports per contract
+* elastic ports that can be assigned to different contracts
+* transfer of channels to another contract
+
+This is inspired by the Agoric design, but also adds considerable complexity to both the `x/wasm`
+implementation as well as the correctness reasoning of any given contract. This will not be
+available in the first version of our "IBC Enabled contracts", but we can consider it for later,
+if there are concrete user cases that would significantly benefit from this added complexity. 
+
+### Add multihop support
+
+Once the ICS and IBC specs fully establish how multihop packets work, we should add support for that.
+Both on setting up the routes with OpenChannel, as well as acting as an intermediate relayer (if that is possible)
+
+## Rejected Ideas
+  
+### One Port per Module
+
+We decided on "one port per contract", especially after the IBC team raised
+the max length on port names to allow `wasm-<bech32 address>` to be a valid port.
+Here are the arguments for "one port for x/wasm" vs "one port per contract". Here 
+was an alternate proposal:
+
+In this approach, the `x/wasm` module just binds one port to handle all
+modules. This can be well defined name like `wasm`. Since we always
+have `(ChannelID, PortID)` for routing messages, we can reuse one port
+for all contracts as long as we have a clear way to map the `ChannelID`
+to a specific contract when it is being established.
+
+
+* On genesis we bind the port `wasm` for all communication with the `x/wasm`
+  module.
+* The *Port* is fully owned by `x/wasm`
+* Each *Channel* is fully owned by one contract.
+* `x/wasm` only accepts *ORDERED Channels* for simplicity of contract
+  correctness.
+
+To clarify:
+
+* When a *Channel* is being established with port `wasm`, the
+  `x/wasm.Keeper` must be able to identify for which contract this
+  is destined. **how to do so**??
+  * One idea: the channel name must be the contract address. This means
+    (`wasm`, `cosmos13d...`) will map to the given contract in the wasm module.
+    The problem with this is that if two contracts from chainA want to
+    connect to the same contracts on chainB, they will want to claim the
+    same *ChannelID* and *PortID*. Not sure how to differentiate multiple
+    parties in this way.
+  * Other ideas: have a special field we send on `OnChanOpenInit` that
+    specifies the destination contract, and allow any *ChannelID*.
+    However, looking at [`OnChanOpenInit` function signature](https://docs.cosmos.network/master/ibc/custom.html#implement-ibcmodule-interface-and-callbacks),
+    I don't see a place to put this extra info, without abusing the version field,
+    which is a [specified field](https://docs.cosmos.network/master/ibc/custom.html#channel-handshake-version-negotiation):
+    ```
+    Versions must be strings but can implement any versioning structure. 
+    If your application plans to have linear releases then semantic versioning is recommended.
+    ... 
+    Valid version selection includes selecting a compatible version identifier with a subset 
+    of features supported by your application for that version.
+    ...    
+    ICS20 currently implements basic string matching with a
+    single supported version.
+    ```

+# Wasm Module
+
+This should be a brief overview of the functionality
+
+## Configuration
+
+You can add the following section to `config/app.toml`:
+
+```toml
+[wasm]
+# This is the maximum sdk gas (wasm and storage) that we allow for any x/wasm "smart" queries
+query_gas_limit = 300000
+# This defines the memory size for Wasm modules that we can keep cached to speed-up instantiation
+# The value is in MiB not bytes
+memory_cache_size = 300
+```
+
+The values can also be set via CLI flags on with the `start` command:
+```shell script
+--wasm.memory_cache_size uint32     Sets the size in MiB (NOT bytes) of an in-memory cache for wasm modules. Set to 0 to disable. (default 100)
+--wasm.query_gas_limit uint         Set the max gas that can be spent on executing a query with a Wasm contract (default 3000000)
+```
+
+## Events
+
+A number of events are returned to allow good indexing of the transactions from smart contracts.
+
+Every call to Instantiate or Execute will be tagged with the info on the contract that was executed and who executed it.
+It should look something like this (with different addresses). The module is always `wasm`, and `code_id` is only present
+when Instantiating a contract, so you can subscribe to new instances, it is omitted on Execute. There is also an `action` tag
+which is auto-added by the Cosmos SDK and has a value of either `store-code`, `instantiate` or `execute` depending on which message
+was sent:
+
+```json
+{
+    "Type": "message",
+    "Attr": [
+        {
+            "key": "module",
+            "value": "wasm"
+        },
+        {
+            "key": "action",
+            "value": "instantiate"
+        },
+        {
+            "key": "signer",
+            "value": "cosmos1vx8knpllrj7n963p9ttd80w47kpacrhuts497x"
+        },
+        {
+            "key": "code_id",
+            "value": "1"
+        },
+        {
+            "key": "_contract_address",
+            "value": "0x5A8D648DEE57b2fc90D98DC17fa887159b69638b"
+        }
+    ]
+}
+```
+
+If any funds were transferred to the contract as part of the message, or if the contract released funds as part of it's executions,
+it will receive the typical events associated with sending tokens from bank. In this case, we instantiate the contract and
+provide a initial balance in the same `MsgInstantiateContract`. We see the following events in addition to the above one:
+
+```json
+[
+    {
+        "Type": "transfer",
+        "Attr": [
+            {
+                "key": "recipient",
+                "value": "0x5A8D648DEE57b2fc90D98DC17fa887159b69638b"
+            },
+            {
+                "key": "sender",
+                "value": "cosmos1ffnqn02ft2psvyv4dyr56nnv6plllf9pm2kpmv"
+            },
+            {
+                "key": "amount",
+                "value": "100000denom"
+            }
+        ]
+    }
+]
+```
+
+Finally, the contract itself can emit a "custom event" on Execute only (not on Init).
+There is one event per contract, so if one contract calls a second contract, you may receive
+one event for the original contract and one for the re-invoked contract. All attributes from the contract are passed through verbatim,
+and we add a `_contract_address` attribute that contains the actual contract that emitted that event.
+Here is an example from the escrow contract successfully releasing funds to the destination address:
+
+```json
+{
+    "Type": "wasm",
+    "Attr": [
+        {
+            "key": "_contract_address",
+            "value": "0x5A8D648DEE57b2fc90D98DC17fa887159b69638b"
+        },
+        {
+            "key": "action",
+            "value": "release"
+        },
+        {
+            "key": "destination",
+            "value": "cosmos14k7v7ms4jxkk2etmg9gljxjm4ru3qjdugfsflq"
+        }
+    ]
+}
+```
+
+### Pulling this all together
+
+We will invoke an escrow contract to release to the designated beneficiary.
+The escrow was previously loaded with `100000denom` (from the above example).
+In this transaction, we send `5000denom` along with the `MsgExecuteContract`
+and the contract releases the entire funds (`105000denom`) to the beneficiary.
+
+We will see all the following events, where you should be able to reconstruct the actions
+(remember there are two events for each transfer). We see (1) the initial transfer of funds
+to the contract, (2) the contract custom event that it released funds (3) the transfer of funds
+from the contract to the beneficiary and (4) the generic x/wasm event stating that the contract
+was executed (which always appears, while 2 is optional and has information as reliable as the contract):
+
+```json
+[
+    {
+        "Type": "transfer",
+        "Attr": [
+            {
+                "key": "recipient",
+                "value": "0x5A8D648DEE57b2fc90D98DC17fa887159b69638b"
+            },
+            {
+                "key": "sender",
+                "value": "cosmos1zm074khx32hqy20hlshlsd423n07pwlu9cpt37"
+            },
+            {

+            }
+        ]
+    },
+    {
+        "Type": "transfer",

+            },
+            {
+                "key": "sender",
+                "value": "0x5A8D648DEE57b2fc90D98DC17fa887159b69638b"
+            },
+            {
+                "key": "amount",
+                "value": "105000denom"
+            }
+        ]
+    },
+    {
+        "Type": "message",
+        "Attr": [
+            {
+                "key": "module",
+                "value": "wasm"
+            },
+            {
+                "key": "action",
+                "value": "execute"
+            },
+            {
+                "key": "signer",
+                "value": "cosmos1zm074khx32hqy20hlshlsd423n07pwlu9cpt37"
+            },
+            {
+                "key": "_contract_address",
+                "value": "0x5A8D648DEE57b2fc90D98DC17fa887159b69638b"
+            }
+        ]
+    }
+]
+```
+
+A note on this format. This is what we return from our module. However, it seems to me that many events with the same `Type`
+get merged together somewhere along the stack, so in this case, you *may* end up with one "transfer" event with the info for
+both transfers. Double check when evaluating the event logs, I will document better with more experience, especially when I
+find out the entire path for the events.
