Vitalik Buterin, the co-founder of Ethereum, has proposed a new Ethereum Improvement Proposal (EIP) alongside Sam Wilson, Ansgar Dietrichs, and Matt Garnett. EIP-7702 aims to refine how account abstraction works on the Ethereum network, potentially shaping the future of user interactions.
Simplifying Complex Transactions: EOAs as Smart Contracts
EIP-7702 introduces a novel transaction type. This allows standard user accounts (EOAs) to temporarily act as smart contract wallets during a specific transaction. Once the transaction is complete, the EOA reverts back to its original state.
This innovation builds upon EIP-3074, a previously considered proposal for the upcoming Pectra upgrade. However, EIP-7702 offers key advantages. According to Uniswap founder Hayden Adams, it adds crucial features like quantum resistance and better compatibility with ERC-4337, a broader standard for smart contract wallets.
The End Game: Seamless User Experience
The ultimate goal of account abstraction is “endgame account abstraction.” This vision involves wallets functioning as smart contracts, enabling a range of sophisticated features. These features could include multi-factor authentication, social recovery mechanisms for lost wallets, and the flexibility to transact with any token.
EIP-7702 is designed to be compatible with this future state, paving the way for a seamless user experience. As the proposal is evaluated by the Ethereum community, it has the potential to redefine how account abstraction is implemented in future network upgrades.
Unlocking Powerful Functionality
The new transaction type proposed in EIP-7702 mirrors functionalities present in EIP-3074. This includes fields for contract code and a signature, allowing for batch transactions and transactions sponsored by another account.
By enabling EOAs to temporarily convert into contracts, they can be integrated into ERC-4337 bundles seamlessly. This compatibility ensures the new system works with existing infrastructure like the EntryPoint, a key component facilitating communication between wallets and smart contracts.
