An Ethereum standard for account abstraction, enabling smart contract wallets to function as user accounts.
ERC-4337 is an Ethereum standard that introduces account abstraction, allowing smart contract wallets to behave like externally owned accounts (EOAs). This enables features such as gas payments in any token, batch transactions, and more flexible security models, all managed by a smart contract rather than a private key. It aims to significantly improve the user experience and flexibility for interacting with the Ethereum network.
