zhongfu commented Dec 1, 2022

There are functions in the contracts that are declared with the virtual specifier. These functions are not expected to be overridden, so the use of the virtual specifier is redundant.

Path

./src/Funnel.sol : computeDomainSeparator(), permit(), permitRenewable(), _checkOnTransferReceived(), _checkOnApprovalReceived(), supportsInterface(), _fallback()

Recommendation

Consider removing redundant code.
