Walkthrough

Added a supportsInterface method override to the ERC7984ERC20Wrapper contract that returns true for the wrapper's own interface ID and delegates other interface queries to its superclass implementation.

Changes

Cohort / File(s)	Summary
Interface Detection Override contracts/token/ERC7984/extensions/ERC7984ERC20Wrapper.sol	Added public view supportsInterface(bytes4 interfaceId) override that checks if the queried interface ID matches the wrapper's own interface and defers to superclass for other IDs

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~5–10 minutes

• Verify that the wrapper's interface ID is correctly identified and returned
• Confirm proper delegation to superclass supportsInterface for non-matching interface IDs
• Check that the override signature aligns with EIP-165 and parent class expectations

Poem

🐰 A wrapper so clever, now speaks for itself,
Detecting its interface with proper finesse—
What am I? it whispers, then defers with good grace,
To ancestors wiser in protocol's place.
Hopping through standards, one method at a time!

66-69: Align supportsInterface with the ERC7984Rwa pattern and fix NatSpec.

The supportsInterface implementation should follow the established pattern in ERC7984Rwa and the base ERC7984 contract:

1. NatSpec correction (line 66): Change /// inheritdoc IERC165 to /// @inheritdoc ERC165 (missing @ prefix and incorrect interface reference).

2. Pattern consistency (line 68): To expose a wrapper-specific ERC-165 interface ID idiomatically, introduce an IERC7984ERC20Wrapper interface describing the wrapper's public API, have this contract implement it, and use type(IERC7984ERC20Wrapper).interfaceId instead. This mirrors the approach used in ERC7984Rwa with IERC7984Rwa and makes the intent explicit.

Once IERC7984ERC20Wrapper exists:

-    /// inheritdoc IERC165
+    /// @inheritdoc ERC165
     function supportsInterface(bytes4 interfaceId) public view virtual override(ERC7984) returns (bool) {
-        return interfaceId == type(ERC7984ERC20Wrapper).interfaceId || super.supportsInterface(interfaceId);
+        return interfaceId == type(IERC7984ERC20Wrapper).interfaceId || super.supportsInterface(interfaceId);
     }
