Account abstraction

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

Providers

It offers modular smart accounts, as well as paymasters and bundlers as a service for sponsoring gas and executing transactions at scale.
