Verify EVM signatures offline

EIP-191 personal messages, EIP-712 typed data, and x402/EIP-3009 payment authorizations (paste a raw Payment-Signature header), recovers the signing wallet, checks it against an expected address, and reports the authorization's amount, payee and validity window. No chain reads.
