Poem

I nibble bytes and hash each name at play,
ENS and WASM make my whiskers sway.
Five quick links hop, profiles bloom in rows,
CI and docker hum as the pipeline grows.
A tiny rabbit patch — into the meadow I go. 🐇✨

Pre-merge checks and finishing touches

❌ Failed checks (1 inconclusive)
Check name Status Explanation Resolution
Title Check ❓ Inconclusive The title "chore: first sketch" is too generic and does not describe the primary change in the changeset; the PR actually adds a substantial initial scaffold including the Linketh WASM contract (with ENS namehashing and tests), CI and security workflows, Docker support, licensing, and documentation. As written the title doesn't help a teammate scanning history understand the main purpose of this PR. Please update the PR title to a concise, descriptive summary of the main change (initial project scaffold and Linketh contract). Examples: "feat(linketh): add Linketh WASM contract with ENS namehash, tests, CI and Docker" or "chore: initial project scaffold — Linketh contract, CI, Docker, README".

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

  • Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
  • Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).

1-5: Tighten links and align naming.

  • Avoid bare URLs; make them proper Markdown links.
  • Optional: Rename link labels from LICENSE-APACHE/ LICENSE-MIT to match actual filenames or keep as-is but consistent.

Apply:

-Except as otherwise noted (below and/or in individual files), this project is licensed under the Apache License, Version 2.0 ([`LICENSE-APACHE`](Apache-2.0) or http://www.apache.org/licenses/LICENSE-2.0) or the MIT license, ([`LICENSE-MIT`](MIT) or http://opensource.org/licenses/MIT), at your option.

1-5: Ensure repo-level license discoverability and crate metadata.

  • Add a top-level LICENSE (or dual-license notice) so GitHub can auto-detect.
  • In Cargo.toml, set: license = "Apache-2.0 OR MIT" and include files under license-file(s) if needed.
licenses/DCO.txt (1)

1-34: LGTM — standard DCO text.

No changes needed. Consider enabling a DCO/sign-off check in CI.

.github/pull_request_template.md (1)

5-10: Optional: expand checklist.

Consider adding items for tests, docs, and CI passing for consistency.

Apply:

 ## Checklist
 - [ ] I have documented these changes where necessary.
+- [ ] I added/updated tests and docs as needed.
+- [ ] CI is green for this PR.
 - [ ] I have read the [DCO][DCO] and ensured that these changes comply.
 - [ ] I assign this work under its [open source licensing][terms].
.idea/.gitignore (1)

1-8: Workspace-specific ignores are good; consider excluding more IDE artifacts

Nice catch ignoring workspace.xml, httpRequests, dataSources. Recommend also ignoring IntelliJ module files and VCS mappings to avoid churn:

 # Default ignored files
 /shelf/
 /workspace.xml
 # Editor-based HTTP Client requests
 /httpRequests/
 # Datasource local storage ignored files
 /dataSources/
 /dataSources.local.xml
+*.iml
+vcs.xml

Also ensure the repo root .gitignore ignores .idea/ (not /idea). If you meant to keep only a curated subset, please confirm and we’ll adjust accordingly.

.idea/vcs.xml (1)

1-7: Avoid committing IDE VCS mappings

This file is user/machine-specific and tends to cause noisy diffs. Prefer ignoring it (see suggested addition vcs.xml in .idea/.gitignore) or remove it from VCS.

rust-toolchain.toml (1)

1-2: Pin to Rust 1.87.0 looks correct; released May 15, 2025

The pin is valid and helps reproducibility. Consider specifying components/targets to keep CI/dev aligned for WASM builds.

 [toolchain]
 channel = "1.87.0"
+components = ["rustfmt", "clippy"]
+targets = ["wasm32-unknown-unknown"]
+profile = "minimal"

(Rust 1.87.0 was released on May 15, 2025.) (blog.rust-lang.org, doc.rust-lang.org)

.env.example (1)

1-4: Reorder keys to satisfy dotenv-linter; add minimal context hints

Ordering is cosmetic but keeps CI linters green. Also, consider adding comments and a CHAIN_ID to avoid mainnet/testnet confusion.

-RPC_URL=
-STYLUS_CONTRACT_ADDRESS=
-PRIV_KEY_PATH=
-ENS_REGISTRY_ADDRESS=0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e
+# Network and RPC
+CHAIN_ID=
+RPC_URL=
+
+# Contract addresses
+STYLUS_CONTRACT_ADDRESS=
+ENS_REGISTRY_ADDRESS=0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e  # Ethereum mainnet
+
+# Local signing
+PRIV_KEY_PATH=

Please confirm which network(s) you target (Arbitrum One/Sepolia vs Ethereum mainnet). The provided ENS registry address is the Ethereum mainnet registry; using it on L2 may require different handling.

.idea/vidalpaul-arb.soul.wasm.iml (1)

1-12: Do not version .iml module files

These are per-IDE/per-user and will churn. Ignore *.iml (see suggested change in .idea/.gitignore) and remove from VCS unless you have a team policy to keep them.

.idea/modules.xml (2)

1-8: Remove IDE metadata from VCS; ignore .idea/ instead.

Committing .idea/* makes builds non-reproducible across dev machines and clutters PRs. Prefer ignoring and regenerating locally.

Apply in .gitignore (see .gitignore comment for exact diff) and purge existing files:

git rm -r --cached .idea

5-5: Module name mismatch with repo; consider renaming for consistency.

vidalpaul-arb.soul.wasm.iml doesn’t reflect the repo linketh-contracts. Recommend aligning module name to the project.

.cargo/config.toml (2)

8-18: macOS dynamic_lookup can hide unresolved symbols.

These flags ease local builds but may mask linkage issues. Consider moving them to a local-only config (.cargo/config.local) or documenting why they’re necessary.


1-6: WASM size/perf tuning belongs in Cargo profiles.

For smaller/faster artifacts, add release profile settings in Cargo.toml instead of relying solely on linker flags.

Example (add to Cargo.toml):

[profile.release]
opt-level = "z"
lto = true
codegen-units = 1
panic = "abort"
.gitignore (1)

6-6: Consider ignoring more local env variants.

Add .env.* to cover .env.test, .env.ci, etc.

-.env
+.env
+.env.*
.github/BRANCH_PROTECTION.md (2)

60-64: Avoid hard-coding test counts.

“All 20 unit tests must pass” will drift. Prefer “All unit tests must pass.”

-- All 20 unit tests must pass
+- All unit tests must pass

75-85: Fix markdownlint: remove trailing colons in headings.

Cleans MD026 violations.

README.md (3)

25-31: Specify a language for the “Project Structure” code fence (MD040).

Add a language hint to silence markdownlint and improve rendering.

`236-243`: **Clarify whether “export-abi” requires a cargo feature.**

If ABI export needs a feature flag, call it out to prevent confusion.

```diff
-cargo stylus export-abi
+# If required in your setup:
+# cargo build --features export-abi
+cargo stylus export-abi

463-466: Use a heading instead of emphasized text (MD036).

Dockerfile (2)

32-38: Dependency caching stub shouldn’t use println! for the wasm target.

Avoid std I/O in the dummy lib to reduce risk of wasm target linkage issues.

 RUN mkdir src && \
     echo "fn main() {}" > src/main.rs && \
-    echo 'fn main() { println!("dummy"); }' > src/lib.rs
+    echo 'pub fn _dummy() {}' > src/lib.rs

28-31: Copy .cargo config early so dependency builds use the same flags/targets.

 COPY Cargo.toml Cargo.lock ./
+COPY .cargo/ ./.cargo/

99-127: Secret scan should cover the whole repo and ignore common directories.

Broaden scope and cut false positives.

20-377: Trim trailing spaces and add a newline at EOF (yamllint).

There are many trailing spaces flagged; please run yamllint/pre-commit to auto-fix.

Cargo.toml (1)

25-30: Feature wiring looks correct; consider documenting default “mini-alloc” tradeoffs

Defaulting to mini-alloc is fine for WASM size, but note fragmentation/throughput tradeoffs. A brief README note would help future contributors.

src/ens.rs (2)

8-12: Mark ENS interface function as view

The registry owner lookup is read-only. Marking it view documents intent and may enable tooling optimizations.

 sol_interface! {
     interface ENS {
-        function owner(bytes32 node) external returns (address);
+        function owner(bytes32 node) external view returns (address);
     }
 }

1-1: Fix fmt failure

CI shows cargo fmt issues in this file. Please run cargo fmt.

src/tests.rs (3)

1-3: Nested tests module inside tests module; flatten to avoid awkward tests::tests::* paths

lib.rs already declares mod tests;. This file then defines another mod tests { ... }, nesting the module. Flatten by removing the inner module wrapper.

-#[cfg(test)]
-mod tests {
-    use super::*;
+// This file is compiled as `mod tests;` from lib.rs. Define tests directly here.
+use super::*;
@@
-}

10-21: Consider adding tests for contract methods (create_profile, delete_profile, transfer_profile, set_quick_links)

Current tests exercise storage directly, not the public API. Add at least one happy-path and one failure-path (e.g., ENS registry not initialized) per method.

I can scaffold stylus-test friendly tests that mock ENS.owner and assert events. Want me to add them?


1-1: Fix fmt failure

CI reports cargo fmt issues in this file. Please run cargo fmt.

src/lib.rs (3)

138-147: Clearing vector by repeated shrink is fine; consider while len > 0 for clarity

Equivalent behavior, slightly clearer and avoids re-reading len in the range.

-        for _ in 0..quick_links_vec.len() {
-            quick_links_vec.shrink();
-        }
+        while quick_links_vec.len() > 0 {
+            quick_links_vec.shrink();
+        }

165-175: Filter quick links on both title and url

Currently only empty titles are filtered. Also skip entries with empty URLs to avoid broken links.

-            let title = link.title.get_string();
-            if !title.is_empty() {
-                result.push((title, link.url.get_string()));

.cargo/config.toml (1)

1-6: Confirm WASM feature flags against Stylus requirements.

Disabling reference-types and enabling bulk-memory seems intentional for engine compat, but please confirm these are required for Arbitrum Stylus and won’t constrain future toolchains.

.github/BRANCH_PROTECTION.md (2)

50-55: Verify stated WASM limits and commands.

“WASM binary size limits (must be under 128KB)” and cargo stylus check usage should be confirmed against current Stylus tooling; the limit may differ.


9-15: Required status check names match actual check-run contexts – the names listed in .github/BRANCH_PROTECTION.md exactly align with the output of gh api …/check-runs (CI Success, Stylus Compatibility Check, Build and Test, Code Validation, Docker Build Test). No update needed.

.dockerignore (1)

72-76: If examples are part of CI or docs, consider keeping them.

Ignoring examples/ may break Docker-stage builds that compile examples. If not needed, ignore is fine; otherwise, remove.

Dockerfile (1)

98-104: Healthcheck and default CMD are good. Consider adding a simple “cargo stylus --version” smoke check.

.github/workflows/ci.yml (1)

175-183: WASM size limit confirmed
Stylus enforces a 128 KiB uncompressed (131 072 bytes) limit and cargo stylus check automatically validates the 24 KiB compressed threshold.

Cargo.toml (1)

17-24: No change needed for Tokio version constraint. The version = "1.12.0" in Cargo.toml uses caret semantics (^1.12.0), allowing any 1.x ≥1.12.0 (Cargo.lock shows it resolved to 1.47.1), so you’re already getting a modern runtime without duplicate pinning.

⚠️ Potential issue

Incorrect protection item: GitHub doesn’t offer “Restrict pushes that create files >100MB” as a branch protection toggle.

Large-file limits are enforced by GitHub globally (100MB) or via Repository Rulesets/LFS, not classic branch protection. Adjust wording or move this to a Ruleset section.

-- ✅ Restrict pushes that create files larger than 100MB
+// Enforce large-file policies via Repository Rulesets or Git LFS (GitHub blocks >100MB by default).

🤖 Prompt for AI Agents
In .github/BRANCH_PROTECTION.md around lines 16 to 26, the document incorrectly
lists "Restrict pushes that create files larger than 100MB" as a branch
protection toggle; update the wording to reflect that GitHub enforces the 100MB
file limit globally or via Repository Rulesets/LFS rather than classic branch
protection, and either remove that bullet or move it into a new "Repository
Rulesets / LFS / Large file limits" section with a brief note explaining where
to configure or enforce large-file restrictions.

⚠️ Potential issue

Anyone can (re)initialize the ENS registry; add a one-time guard

init is publicly callable and can be invoked multiple times to change the registry address. This is a critical security issue.

Apply a one-time initialization guard (minimal change):

 pub fn init(&mut self, ens_registry_address: Address) {
-    self.ens_registry.set(ens_registry_address);
+    assert!(
+        self.ens_registry.get().is_zero(),
+        "Already initialized"
+    );
+    self.ens_registry.set(ens_registry_address);
 }

Optionally, add an admin field set on first call to restrict future admin ops.

In src/lib.rs around lines 69 to 73, the public init allows repeated
reinitialization of the ENS registry; change it to enforce one-time
initialization by checking whether the stored ens_registry is still the
default/zero value and returning an error or panicking if it's already set, and
only set the address on the first successful call; optionally capture and store
the caller as an admin during that first call to gate future admin-only
operations.

namehash to pass a &str (e.g. call ens::namehash(&ens_name) rather than cloning
the String) and replace the blind unwrap on the ENS owner call with proper error
handling that surfaces the underlying call error (use expect with a clear

returned error details), then keep the ownership check against sender as before.

Transfers can exceed the 5-link limit and do not emit an event

set_quick_links enforces max 5 links, but transfer_profile copies all links, bypassing the cap. Also consider emitting an event for observability.

Cap to 5 and emit QuickLinksUpdated:

-            let mut new_links = self.quick_links.setter(new_owner);
+            let mut new_links = self.quick_links.setter(new_owner);
             // Clear existing links

-                new_links.shrink();
-            }
-            for (title, url) in link_data {
+            while new_links.len() > 0 {
+                new_links.shrink();
+            }
+            for (idx, (title, url)) in link_data.into_iter().enumerate() {
+                if idx >= 5 { break; } // enforce same cap as set_quick_links
                 let mut new_link = new_links.grow();
                 new_link.title.set_str(&title);
                 new_link.url.set_str(&url);
             }

Optionally after all copies:

log(self.vm(), QuickLinksUpdated { owner: new_owner });
🤖 Prompt for AI Agents
In src/lib.rs around lines 179 to 234, transfer_profile currently copies all
quick links from sender to new_owner (bypassing the 5-link cap) and doesn’t emit
an event; fix by limiting copied links to a maximum of 5 (e.g., iterate only up
to old_links.len().min(5)) when building link_data and when populating
new_links, ensure you clear existing target links safely (shrink until length ==
0) then grow exactly for the capped items; after finishing the copy, emit the
QuickLinksUpdated event (log(self.vm(), QuickLinksUpdated { owner: new_owner }))
so observers see the change.

In src/main.rs around lines 7 to 10, the conditional main references an
undeclared crate stylus_hello_world which breaks builds; replace this leftover
template call by either making the export-abi main a no-op (e.g., an empty
function body) or invoking the actual ABI export path from this crate (call your
crate's function/module instead). Update the #[cfg(feature = "export-abi")] fn
main to remove the stylus_hello_world::print_from_args() call and either leave
it empty or call the correct function from your crate that performs the ABI
export.

118-123: Codecov input key and token.

codecov-action v4 expects "files" (plural). Also verify whether a CODECOV_TOKEN is required for this repo visibility.

-        file: ./cobertura.xml
-        fail_ci_if_error: false
+      with:
+        files: ./cobertura.xml
+        fail_ci_if_error: false
+        # token: ${{ secrets.CODECOV_TOKEN }}  # if repository is private

114-117: Ensure tarpaulin emits cobertura.xml at repo root.

Tarpaulin’s format flag is case-sensitive in some versions; safer to use Xml and set output dir.

-        cargo install cargo-tarpaulin
-        cargo tarpaulin --lib --out xml --timeout 120
+        cargo install cargo-tarpaulin
+        cargo tarpaulin --lib --out Xml --output-dir . --timeout 120

216-220: Confirm cargo-stylus exists in runtime image.

These commands will fail if the runtime stage doesn’t install cargo-stylus.

Do you want a quick Dockerfile patch to ensure cargo-stylus is present in runtime?

76-76: step must run script with "run" section or run action with "uses" section

(syntax-check)

🤖 Prompt for AI Agents
.github/workflows/ci.yml around lines 76 to 82: there are two steps with the
exact same name "Setup Rust toolchain" causing an actionlint duplicate-name
error; remove the duplicate entry (or rename one if both are required for
different actions) so each step name is unique, ensuring you keep the step that
includes the dtolnay/rust-toolchain action with the toolchain and targets fields
and delete the redundant step, then validate the YAML to ensure indentation and
sequence are preserved.

112-116: Make coverage output deterministic for upload.

Explicitly set output format and path so the subsequent upload step can find it.

-        cargo install cargo-tarpaulin
-        cargo tarpaulin --lib --out xml --timeout 120
+        cargo install --locked cargo-tarpaulin
+        cargo tarpaulin --lib --out Xml --output-dir . --timeout 120

117-123: Codecov: use correct input key and align path.

codecov-action expects “files”, not “file”. Also ensure the filename matches tarpaulin output.

-      uses: codecov/codecov-action@v4
-      with:
-        file: ./cobertura.xml
-        fail_ci_if_error: false
+      uses: codecov/codecov-action@v4
+      with:
+        files: ./cobertura.xml
+        fail_ci_if_error: false

If this is a private repo, set CODECOV_TOKEN in repo secrets. Please confirm the coverage file exists in CI logs after the tarpaulin step.


30-48: Simplify and harden cargo caching.

Replace manual registry/build caches with Swatinem/rust-cache for correctness and less churn.

-    - name: Cache cargo registry
-      uses: actions/cache@v4
-      with:
-        path: |
-          ~/.cargo/registry/index
-          ~/.cargo/registry/cache
-          ~/.cargo/git/db
-        key: ${{ runner.os }}-cargo-registry-${{ hashFiles('**/Cargo.lock') }}
-        restore-keys: |
-          ${{ runner.os }}-cargo-registry-
-          
-    - name: Cache cargo build
-      uses: actions/cache@v4
-      with:
-        path: target
-        key: ${{ runner.os }}-cargo-build-${{ hashFiles('**/Cargo.lock') }}
-        restore-keys: |
-          ${{ runner.os }}-cargo-build-
+    - name: Cache cargo (build + registry)
+      uses: Swatinem/rust-cache@v2
+      with:
+        cache-on-failure: true

Apply similarly to other jobs that build Rust (81-99, 142-160, etc.).


161-166: Pin CLI install for reproducibility.

Pin versions and use --locked to avoid upstream breakages.

-    - name: Install Stylus CLI

+    - name: Install Stylus CLI
+      run: |
+        cargo install --locked --force cargo-stylus@<version>
+        cargo install --locked --force cargo-stylus-check@<version>

Replace with known-good versions.


297-298: Repeat: pin Stylus CLI installs here too.

-    - name: Install Stylus CLI
-      run: cargo install --force cargo-stylus cargo-stylus-check
+    - name: Install Stylus CLI
+      run: |
+        cargo install --locked --force cargo-stylus@<version>
+        cargo install --locked --force cargo-stylus-check@<version>

170-179: Harden WASM size check against missing file.

Guard for absent artifact to produce a clearer failure.

-        WASM_SIZE=$(stat -c%s target/wasm32-unknown-unknown/release/linketh.wasm)
+        WASM=target/wasm32-unknown-unknown/release/linketh.wasm
+        [ -f "$WASM" ] || { echo "❌ $WASM not found"; exit 1; }
+        WASM_SIZE=$(stat -c%s "$WASM")
         echo "WASM size: $WASM_SIZE bytes"
         if [ $WASM_SIZE -gt 131072 ]; then  # 128KB limit

55-59: Pin cargo-audit install.

Use --locked and a version to reduce CI flakiness.

-        cargo install cargo-audit
+        cargo install --locked cargo-audit@<version>

373-373: Add newline at end of file.

YAMLlint warning.

-        fi
\ No newline at end of file

75-81: Fix duplicate step and avoid @master ref.

Two consecutive “Setup Rust toolchain” step names; first has no run/uses (actionlint error). Also, avoid using the action’s @master ref.

135-141: Update to maintained Rust toolchain action.

actions-rs/toolchain@v1 is too old on GHA. Switch to dtolnay/rust-toolchain and adjust inputs.

-    - name: Setup Rust toolchain

195-219: Confirmed: runtime image provides cargo and cargo-stylus.
Runtime stage (FROM rust:1.78-slim) runs RUN cargo install --force cargo-stylus cargo-stylus-check and uses the Rust image (cargo present), so the CI commands should succeed.
