A contract implements isValidSignature to verify that a signature is valid according to its logic. Applications call this method instead of assuming an EOA signature. This lets contracts participate in signing flows.
ERC-1271 lets smart wallets sign messages and transactions, enabling recovery and multisig verification. It is essential for account abstraction and on-chain identity. It is a foundational standard.
