Account Abstraction


This page includes providers that meet specific inclusion criteria, as outlined below. Please visit the community account abstractions page (opens in a new tab) for an additional listing of third-party account abstraction tools.

ERC-4337 (opens in a new tab), also known as Account Abstraction, enables more opportunities for apps and wallet developers to innovate on user experiences, including the ability to:

  • Batch transactions together (e.g. approve and execute a swap in one go)
  • Offer wallets with easy recovery and no seed phrase
  • Sponsor the gas fees for transactions
  • Enable users to pay gas in the token(s) of their choice

Superchain Paymaster

The Superchain paymaster is an ERC-4337 verifying paymaster that sponsors transactions for smart accounts on the Superchain. Use the Superchain Paymaster to get your transactions sponsored to remove friction from your app experience. View the implementation guide and tutorials here. (opens in a new tab)
