Account Abstraction (EIP-4337)

What Account Abstraction (EIP-4337) requires

EIP-4337 (Account Abstraction Using Alt Mempool) is an Ethereum Improvement Proposal finalized in March 2023 that enables programmable smart contract wallets to replace externally owned accounts (EOAs) as the primary transaction signing mechanism, without requiring changes to the Ethereum protocol consensus layer. The standard introduces a new transaction object called a UserOperation, a permissionless Bundler network that aggregates UserOperations into standard transactions, a singleton EntryPoint contract that validates and executes UserOperations, and a Paymaster contract that enables third-party gas sponsorship. For AI agents, EIP-4337 is foundational because it enables agents to operate programmable wallets with built-in spending limits, multi-signature authorization requirements, social recovery, and gas abstraction - removing the requirement for agents to hold ETH for gas fees and enabling human-readable authorization rules enforced by smart contract logic.
