abstraxn_account.js

abstraxn_account.js is a TypeScript library built on top of viem for deploying and managing ERC-4337 smart accounts, interacting with bundlers and paymasters, and leveraging custom signers.

Features

• High-Level Smart Account Support: We support a high-level API for deploying and managing smart accounts, including some of the most popular implementations (Safe, Kernel, Biconomy, etc.)
• Bundler Support: We support all bundler actions following ERC-4337.
• Gas Sponsorship: We support paymaster actions to allow you to easily sponsor gas fees.
• User Operation Utility Functions: We provide many low-level utility functions useful for dealing with User Operations.
• Modular and Extensible: We allow you to easily create and plug in your own smart account systems, bundlers, paymasters, and signers.
• Built on & for viem: abstraxn_account.js is designed to be a thin wrapper around viem, maintaining the same style and overall feel viem provides.
• and a lot more...
