Ethereum & Smart Contracts

Account Abstraction

Also: AA, ERC-4337, Smart Wallet

Giving a wallet account smart-contract features that a plain key-only account lacks: recovering access through trusted contacts, letting someone else pay the gas, batching several actions into one, or setting spending limits. It can be done with dedicated smart-contract accounts (ERC-4337) or, since Ethereum's May 2025 Pectra upgrade, by letting an ordinary account delegate to smart-contract code (EIP-7702).
