## Definition

The Ethereum standard that enables account abstraction without changing the consensus layer. Users submit UserOperations to a separate mempool; bundlers package them into transactions, and optional paymasters can sponsor gas. ERC-4337 underpins many 2025–2026 smart-wallet products that offer recovery, batching, and gas abstraction while remaining non-custodial. Also searched as: EIP-4337, account abstraction standard.
