Poem

A change for the chains, a hop for the code,
Now chain IDs as strings on the legacy road.
No more number confusion, just clear bunny logic,
With a version hop forward—how methodic!

3-3: LGTM! Correct semantic versioning for bugfix.

The patch version bump from 4.1.0 to 4.1.1 correctly follows semantic versioning conventions for a bugfix release.

backend/src/paymaster/index.ts (4)

64-64: LGTM! Correct type definition for string-based chain ID handling.

The interface change from number[] to string[] properly reflects the intended usage of chain IDs as strings in the configuration.


82-82: LGTM! Property type updated consistently.

The class property type correctly matches the interface definition.


96-96: LGTM! Simplified constructor assignment.

The constructor now directly assigns the string array without unnecessary number conversion, which aligns with the corrected type definition.


1133-1133: LGTM! Consistent string comparison fix applied across all usage sites.

All five locations where skipType2Txns is checked now correctly convert chainId to string before comparison using chainId.toString(). This ensures consistent behavior and fixes the type mismatch that was causing the bug.

The fix is comprehensive and addresses:

  • whitelistAddresses method (line 1133)
  • removeWhitelistAddress method (line 1186)
  • deposit method (line 1250)
  • deployVp method (line 1313)
  • addStake method (line 1360)

Also applies to: 1186-1186, 1250-1250, 1313-1313, 1360-1360

Fix markdown formatting issues.

The changelog entry correctly documents the bugfix, but there are formatting issues that should be addressed:

🤖 Prompt for AI Agents
In backend/CHANGELOG.md around lines 2 to 4, the markdown formatting of the
changelog entry is incorrect. Fix the formatting by ensuring the version header
is properly formatted as a markdown heading (e.g., starting with ## and a
space), and the bullet point describing the fix is correctly indented and uses a
hyphen followed by a space. Remove any trailing spaces or formatting
inconsistencies to comply with standard markdown syntax.
