Signature verify, EIP-191
Signature verify, EIP-191. Verify an Ethereum personal_sign (EIP-191) signature: recover the address that signed a message and, given an expected address, say whether it matches. Works for ordinary wallets (EOAs); smart-contract wallets sign by ERC-1271, which this offline check does not cover. Use for sign-in-with-wallet, proving wallet ownership or checking a signed order. A malformed signature is 400, uncharged.
