Vitalik Buterin Suggests EIP-7702 to Enhance Account Abstraction on Ethereum

Ethereum would possibly quickly expertise a major enhancement with the introduction of EIP-7702. Proposed by co-founder Vitalik Buterin, this improve focuses on bettering “account abstraction” on the blockchain platform.

  • Vitalik Buterin and his co-authors launched EIP-7702 as an alternative to EIP-3074 to enhance the abstraction of accounts in Ethereum.
  • This proposal permits externally owned accounts (EOAs) to operate as sensible contract wallets quickly throughout a transaction, then return to their preliminary state afterward.

EIP 7702 Goals to Enhance Safety and Compatibility

As per the Github abstract, EIP 7702 stands out as a vital various to the present EIP-3074, tackling main vulnerabilities by steering away from opcodes which can be anticipated to change into out of date and avoiding fragmentation inside the ecosystem. It’s designed to be forward-compatible with future quantum computing developments and goals for seamless integration with EIP 4337, which is more and more vital as quantum know-how progresses.

Authored by Vitalik Buterin, Sam Wilson, Ansgar Dietrichs, and Matt Garnett, the EIP presents a novel transaction kind that quickly transforms consumer accounts into sensible contract wallets. This innovation permits advanced operations, equivalent to combining a number of actions right into a single transaction, thereby boosting the community’s effectivity and suppleness.

EIP 7702 claims to streamline consumer interactions and decrease transaction prices on decentralized change (DEX) platforms by eradicating the necessity for a number of transaction steps, representing a major development over present limitations. The neighborhood appears extremely on this new proposal.

A key function of EIP 7702 is its focus on enhancing consumer safety and autonomy. In accordance to the Github abstract, it permits customers to signal transactions with momentary, particular permissions, thereby minimizing dangers associated to key compromises. This facet not solely will increase consumer belief within the system but in addition strengthens the Ethereum community’s functionality to tackle each current and future safety challenges successfully.

When Buterin and his co-authors offered their EIP, it garnered vital consideration for its quantum resistance, addressing long-standing issues within the cryptocurrency neighborhood about the specter of quantum computing. This proposal is seen as a proactive measure to mitigate potential quantum threats.

Key Enhancements Launched by EIP-7702

Enhanced Safety

EIP-7702 eliminates the everlasting delegation facet seen in EIP-3074, lowering the danger of funds being stolen by malicious contracts.

Smooth Fork Compatibility

Not like EIP-3074, EIP-7702 can probably be carried out by way of a comfortable fork, making it a much less disruptive community improve.

Improved Compatibility

EIP-7702 is designed to be suitable with the ERC-4337 commonplace, selling a extra unified method to account abstraction.

Quantum Resistance

EIP-7702 is considered extra resistant to quantum computing threats than EIP-3074, providing higher future-proof safety.

How EIP-7702 Achieves These Enhancements

New Transaction Kind

EIP-7702 introduces a brand new transaction kind with fields for contract code and a signature. In the course of the transaction, the signer’s account code is quickly changed with the supplied contract code, which dictates how the transaction is executed. After the transaction is accomplished, the account code reverts to its unique empty state.

Operate Calls As a substitute of Opcodes

As a substitute of introducing new opcodes like EIP-3074, EIP-7702 defines features to be known as inside the transaction. This method supplies extra flexibility and eliminates the necessity for a tough fork.

Built-in Method

EIP-7702 proposes a streamlined and extra built-in methodology, mixing the safety and ease of EOAs with the flexibleness of sensible contracts. At the beginning of the transaction, the EOA’s contract_code subject is quickly set to a particular sensible contract required for the transaction. As soon as the transaction is full, the contract_code is cleared, and the EOA reverts to its unique state. This methodology avoids the necessity for brand spanking new opcodes and the related onerous forks by utilizing callable features that may seamlessly combine with Ethereum’s present infrastructure. Jarrod Watts, developer relations engineer at Polygon, remarked.

Limitations of Externally Owned Accounts (EOAs)

Restricted Capabilities

At the moment, Ethereum customers work together with the community by way of externally owned accounts (EOAs), that are easy accounts linked to personal keys. Whereas EOAs present primary performance, they’ve a number of limitations. EOAs can solely carry out easy duties, equivalent to transferring tokens to different EOAs and initiating transactions that set off one other sensible contract transaction.

Safety Vulnerabilities

EOAs rely on personal keys, which function a single level of failure. If the personal secret’s compromised, hackers can achieve entry to and steal all of the funds related to the account. This makes EOAs notably weak to safety breaches.

Account Abstraction on Ethereum

Ethereum employs two account fashions: externally owned accounts (EOAs) and contract accounts. EOAs, managed by personal keys, have restricted capabilities and safety features, limiting their use in advanced transactions involving sensible contracts. To deal with these limitations, Ethereum launched a number of EIPs, together with EIP-4337, EIP-3074, and EIP-5003.


Carried out in March 2023, EIP-4337 established a framework that enables sensible contracts to operate as accounts, able to validating and executing transactions.


Proposed prior to EIP-4337, EIP-3074 aimed to improve EOAs by quickly delegating their transaction authority to sensible contracts.


Constructing on EIP-3074, EIP-5003 launched the AUTHUSURP opcode, enabling the everlasting conversion of an EOA into a sensible contract account.

Recap of EIP-3074

To beat the restrictions of EOAs, EIP-3074 was proposed to improve their performance. This proposal launched two new opcodes: AUTH and AUTHCALL. AUTH permits EOAs to authorize particular sensible contracts to act on their behalf, whereas AUTHCALL permits these licensed sensible contracts to execute transactions for the EOA.

The proposal additionally launched the idea of third-party transaction sponsorship, the place another person may pay transaction charges on behalf of a consumer, thereby bettering the consumer expertise. Moreover, customers may mix a number of transactions right into a single one, lowering transaction charges. This aimed to make Ethereum extra accessible to customers unfamiliar with fuel charges or with out entry to ETH.

Nonetheless, EIP-3074 had a number of drawbacks:

Safety Issues

The delegation course of raised safety points. Malicious sensible contracts, if licensed, may probably drain consumer funds.

Exhausting Fork Requirement

Implementing EIP-3074 required a tough fork, a significant community improve that may be disruptive.

Restricted Compatibility

EIP-3074 didn’t combine nicely with the rising ERC-4337 commonplace for sensible contract wallets.

Peoples Response on this

The Ethereum neighborhood has responded favorably to EIP-7702. Many view it as an important development for broader adoption of sensible contract wallets, offering enhanced safety and elevated performance. Moreover, some spotlight its potential for higher interoperability with different blockchains, thanks to its compatibility with the ERC-4337 commonplace. This implies that EIP-7702 may successfully tackle long-standing limitations and contribute to a safer and versatile Ethereum ecosystem.


Future Outcomes

Whereas EIP-7702 affords a promising future, there are a number of concerns for its adoption:

Group Consensus

The Ethereum neighborhood should attain an settlement on implementing EIP-7702, which can contain discussions, testing, and potential revisions to the proposal.

Pockets Supplier Integration

Pockets suppliers, equivalent to MetaMask, will want to replace their software program to assist EIP-7702 transactions, which is essential for consumer adoption.

Sensible Contract Safety

The safety of the sensible contract code utilized in EIP-7702 transactions is significant. Customers want to make sure the code they execute is from a trusted supply.

Regardless of these challenges, the potential advantages of EIP-7702 are substantial. If efficiently carried out, it may herald a brand new period for Ethereum, offering customers with a safer and versatile expertise whereas paving the best way for superior account abstraction sooner or later.
