Warn		Potential code anomaly (AI signal): npm @metamask/transaction-controller is 75.0% likely to have a medium risk anomaly Notes: The code performs straightforward signature verification using ethers.js, returning true when the recovered signer matches the provided publicKey. While generally safe, the silent catch and potential mismatch between data formatting and signing process should be addressed to avoid silent failures. Overall, a benign utility with moderate input-format sensitivity.
