Ethereum co-founder Vitalik Buterin, together with collaborators Sam Wilson, Ansgar Dietrichs, and Matt Garnett, has proposed a brand new Ethereum Enchancment Proposal (EIP) numbered 7702, designed to considerably improve the performance of Ethereum’s externally owned accounts (EOAs). EIP-7702 goals to combine sensible contract functionalities quickly into EOAs, a transformative idea which may redefine person interactions on the Ethereum community.
Evolution Of Account Abstraction On Ethereum
Ethereum’s account mannequin contains two major sorts: externally owned accounts (EOAs) and contract accounts. EOAs are managed by private keys and have restricted capabilities and security measures, which limit their use in additional advanced transactions sometimes reserved for sensible contracts.
To handle these limitations, a number of EIPs have been launched:
- EIP-4337: Carried out in March 2023, it established a framework permitting sensible contracts to behave as accounts that may validate and execute transactions, often called Consumer Operations (UserOps). This proposal considerably enhanced person expertise by integrating superior functionalities like biometrics, particularly in purposes developed by platforms resembling Polygon and Coinbase.
- EIP-3074: Proposed earlier than EIP-4337, it aimed to empower EOAs by permitting them to delegate their transaction authority to sensible contracts quickly. This proposal included two new opcodes, AUTH and AUTHCALL, to facilitate this delegation, though it raised safety considerations concerning potential misuse by malicious contracts.
- EIP-5003: Constructing on EIP-3074, this proposal launched the AUTHUSURP opcode to allow a everlasting transformation of an EOA into a sensible contract account, addressing some compatibility points with EIP-4337 but additionally creating potential fragmentation in account abstraction methodologies.
Progressive Elements of EIP-7702
The introduction of EIP-7702 is a response to the advanced panorama formed by its predecessors. It proposes a leaner, extra built-in strategy by permitting EOAs to quickly undertake sensible contract code throughout transactions, thereby combining the safety and ease of EOAs with the flexibility of smart contracts.

Right here’s how EIP-7702 works: Initially of a transaction, the EOA’s contract_code subject is quickly set to a particular sensible contract code obligatory for the transaction. This code executes the transaction, leveraging sensible contract functionalities. Upon completion of the transaction, the contract_code is cleared, reverting the EOA to its unique state.
This course of bypasses the necessity for brand new opcodes and the related arduous forks, because it makes use of callable features (confirm for AUTH and execute for AUTHCALL) as a substitute, which might combine seamlessly with the prevailing Ethereum infrastructure.
Jarrod Watts, a developer relations engineer at Polygon, highlighted the importance of EIP-7702, remarking, “Vitalik simply proposed EIP-7702. It’s one of the vital impactful adjustments Ethereum goes to have… EVER.” The group’s response underscores the transformative potential of EIP-7702 in bridging the hole between conventional EOAs and extra dynamic sensible contract accounts.
“EIP-7702 represents a fusion of the pliability of sensible contracts with the foundational safety mannequin of EOAs,” Watts commented. “It’s a major stride in the direction of making Ethereum extra accessible and safe for on a regular basis customers.”

So, this is every thing you must learn about the way it works and the way we received right here:

If adopted, EIP-7702 might essentially change how customers work together with decentralized purposes (dApps) and handle digital property on the Ethereum community. By enabling EOAs to quickly function with the superior options of sensible contracts, EIP-7702 guarantees a seamless, safer person expertise that would speed up the adoption of Ethereum’s extra refined capabilities.
Nevertheless, the success of EIP-7702 will depend on thorough testing, group consensus, and cautious consideration of safety implications, notably how short-term sensible contract codes are managed and revoked.
At press time, ETH traded at $2,997.
