Compiling

To compile all the contracts, run the following in the repo root:

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/workspace-optimizer:0.12.4

This will compile all packages in the contracts directory and output the stripped and optimized wasm code under the artifacts directory as output, along with a checksums.txt file.

If you hit any issues there and want to debug, you can try to run the following in each contract dir: RUSTFLAGS="-C link-arg=-s" cargo build --release --target=wasm32-unknown-unknown --locked

Creating a new contract

You can start with cosmwasm-template as a basis:

cd contracts
cargo generate --git https://github.com/CosmWasm/cosmwasm-template.git --name CONTRACT_NAME
cd CONTRACT_NAME

# remove unneeded files
rm -rf .circleci .github .git
rm .cargo-ok .editorconfig .gitignore rustfmt.toml
rm Developing.md Importing.md Publishing.md LICENSE NOTICE

# regenerate schema for CI tests
cargo schema

git add .

Then add it to CI, by editing .circleci/config.yml.

Finally, update Cargo.toml to use the current version used by all other contracts in this repo.
