Ethereum co-founder Vitalik Buterin, together with collaborators Sam Wilson, Ansgar Dietrichs, and Matt Garnett, has proposed a brand new Ethereum Improvement 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 briefly into EOAs, a transformative idea which may redefine consumer interactions on the Ethereum community.
Evolution Of Account Abstraction On Ethereum
Ethereum’s account mannequin contains two main sorts: externally owned accounts (EOAs) and contract accounts. EOAs are managed by private keys and have restricted capabilities and safety features, which prohibit their use in additional complicated transactions usually reserved for sensible contracts.
To tackle these limitations, a number of EIPs have been launched:
- EIP-4337: Implemented in March 2023, it established a framework permitting sensible contracts to behave as accounts that may validate and execute transactions, often called User Operations (UserOps). This proposal considerably enhanced consumer expertise by integrating superior functionalities like biometrics, particularly in purposes developed by platforms comparable to 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 briefly. This proposal included two new opcodes, AUTH and AUTHCALL, to facilitate this delegation, though it raised safety issues relating to potential misuse by malicious contracts.
- EIP-5003: Building on EIP-3074, this proposal launched the AUTHUSURP opcode to allow a everlasting transformation of an EOA into a wise contract account, addressing some compatibility points with EIP-4337 but additionally creating potential fragmentation in account abstraction methodologies.
Innovative Aspects of EIP-7702
The introduction of EIP-7702 is a response to the complicated panorama formed by its predecessors. It proposes a leaner, extra built-in method by permitting EOAs to briefly undertake sensible contract code throughout transactions, thereby combining the safety and ease of EOAs with the flexibility of smart contracts.

Here’s how EIP-7702 works: At the beginning of a transaction, the EOA’s contract_code discipline is briefly set to a selected sensible contract code crucial 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 authentic state.
This course of bypasses the necessity for brand spanking new opcodes and the related exhausting forks, because it makes use of callable features (confirm for AUTH and execute for AUTHCALL) as an alternative, which may combine seamlessly with the prevailing Ethereum infrastructure.
Jarrod Watts, a developer relations engineer at Polygon, highlighted the importance of EIP-7702, remarking, “Vitalik just proposed EIP-7702. It’s one of the most impactful changes Ethereum is going 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 flexibility of smart contracts with the foundational security model of EOAs,” Watts commented. “It’s a significant stride towards making Ethereum more accessible and secure for everyday users.”

So, here is every thing it’s essential learn about the way it works and the way we acquired right here:

If adopted, EIP-7702 may basically change how customers work together with decentralized purposes (dApps) and handle digital belongings on the Ethereum community. By enabling EOAs to briefly function with the superior options of sensible contracts, EIP-7702 guarantees a seamless, safer consumer expertise that would speed up the adoption of Ethereum’s extra subtle capabilities.
However, the success of EIP-7702 is dependent upon thorough testing, group consensus, and cautious consideration of safety implications, significantly how momentary sensible contract codes are managed and revoked.
At press time, ETH traded at $2,997.
