Infinitism (ERC-4337)

Infinitism maintains the documentation and reference implementation for ERC-4337, the Ethereum standard that enables Account Abstraction (AA) without protocol-level changes. It provides technical resources for developers building or integrating smart contract wallets, paymasters, and bundlers.

Infinitism (ERC-4337) - Account Abstraction

Project Links

Description

ERC 4337 is an account abstraction proposal that avoids the need for consensus-layer protocol changes by introducing a higher-layer pseudo-transaction object called a UserOperation. This allows users to send UserOperation objects into a new separate mempool, which are then packaged by bundlers into a single transaction for inclusion in a block. The proposal aims to improve wallet designs and reduce complexity for end users by shifting from EOAs to smart contract wallets with arbitrary verification logic.
