Overview of how Abstract is using Account Abstraction

What is Account Abstraction (AA) ?

Account abstraction (AA), from EIP-4337, enables the use of smart contracts as wallets, as opposed to EOAs like Metamask (EOA: External Owned Account : public/private key pair ). It provides a standardized way for smart contracts to act as a wallet and handle transactions.

It was implemented with ERC-4337 on Ethereum in March 2023, but got different "upgrades" like the EIP-7702 from May 2024.

Currently, AA is used to improve onboarding experience and UX, like paymasters functionalities (free gas fees or payment using ERC-20 tokens other than ETH).

How does Abstract use AA ?

Even though Abstract's AA and Ethereum's EIP-4337 both aim to enhance accounts' flexibility and user experience, they differ on 4 critical aspects :

  • Implementation Level - Abstract's approach to AA is to build it natively to the protocol which can be called Native Account Abstraction (NAA), whereas EIP 4337 avoids the implementation at the protocol level.

  • Account Types - On Abstract all accounts (even EOAs) behave like smart contract accounts; all accounts support paymasters.

  • Transaction Processing - On Abstract, there is a single mempool (waiting areas for transactions) and transaction flow.

  • Paymaster Support - Abstract allows both EOAs and smart contract accounts to benefit from paymasters thanks to its single transaction flow

To put it simply :

The main goal is to make the onboarding flow better for users and easier for devs.
