Dai Stablecoin (DAI) Smart Contract Risk

Permit No-Op / Non-Standard Permit

⚡ MEDIUM severity

Vulnerability

DAI implements a non-standard permit function (using nonces differently and with a different signature format than EIP-2612). Protocols assuming standard EIP-2612 permit may encounter unexpected behavior.

Safe integration

If using permit with DAI, use DAI-specific permit parameters (holder, spender, nonce, expiry, allowed). Do not assume EIP-2612 compatibility.
