Signature phishing check before an agent signs: decodes EIP-712 typed data (ERC-20 permit, Permit2 allowance or transfer, Seaport order, transfer authorization) or an x402 payment request, says in one sentence what signing would allow, screens every spender and payee for sanctions and scams, and catches drainer patterns (permits to plain wallets, sell-for-nothing orders, fake USDC domains, over-priced x402 payments). Verdict proceed/caution/avoid. Category: security.
