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 choice to EIP-3074 to enhance the abstraction of accounts in Ethereum.
This proposal permits externally owned accounts (EOAs) to operate as good contract wallets briefly throughout a transaction, then return to their preliminary state afterward.
What’s EIP 7702 ?
EIP 7702 Goals to Enhance Safety and Compatibility
As per the Github abstract, EIP 7702 stands out as a vital different to the present EIP-3074, tackling main vulnerabilities by steering away from opcodes which might be anticipated to turn into out of date and avoiding fragmentation inside the ecosystem.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 sort that briefly transforms person accounts into good contract wallets. This innovation permits complicated operations, similar to combining a number of actions right into a single transaction, thereby boosting the community’s effectivity and adaptability.
EIP 7702 claims to streamline person interactions and decrease transaction prices on decentralized trade (DEX) platforms by eradicating the necessity for a number of transaction steps, representing a major development over present limitations. The group appears extremely on this new proposal.
A key function of EIP 7702 is its concentrate on enhancing person safety and autonomy. In keeping with the Github abstract, it permits customers to signal transactions with short-term, particular permissions, thereby minimizing dangers associated to key compromises. This facet not solely will increase person belief within the system but in addition strengthens the Ethereum community’s functionality to handle 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 group 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, decreasing the chance of funds being stolen by malicious contracts.
Comfortable Fork Compatibility
Not like EIP-3074, EIP-7702 can probably be carried out by way of a tender fork, making it a much less disruptive community improve.
Improved Compatibility
EIP-7702 is designed to be appropriate with the ERC-4337 customary, selling a extra unified method to account abstraction.
Quantum Resistance
EIP-7702 is considered extra immune to quantum computing threats than EIP-3074, providing higher future-proof safety.
How EIP-7702 Achieves These Enhancements
New Transaction Sort
EIP-7702 introduces a brand new transaction sort with fields for contract code and a signature. In the course of the transaction, the signer’s account code is briefly 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.
Perform 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 Strategy
EIP-7702 proposes a streamlined and extra built-in methodology, mixing the safety and ease of EOAs with the pliability of good contracts. Initially of the transaction, the EOA’s contract_code subject is briefly set to a particular good 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 laborious 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 present, Ethereum customers work together with the community by means of externally owned accounts (EOAs), that are easy accounts linked to non-public keys. Whereas EOAs present primary performance, they’ve a number of limitations. EOAs can solely carry out easy duties, similar to transferring tokens to different EOAs and initiating transactions that set off one other good contract transaction.
Safety Vulnerabilities
EOAs depend on non-public keys, which function a single level of failure. If the non-public key’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 non-public keys, have restricted capabilities and security measures, limiting their use in complicated transactions involving good contracts. To deal with these limitations, Ethereum launched a number of EIPs, together with EIP-4337, EIP-3074, and EIP-5003.
EIP-4337
Carried out in March 2023, EIP-4337 established a framework that enables good contracts to operate as accounts, able to validating and executing transactions.
EIP-3074
Proposed previous to EIP-4337, EIP-3074 aimed to reinforce EOAs by briefly delegating their transaction authority to good contracts.
EIP-5003
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 constraints of EOAs, EIP-3074 was proposed to reinforce their performance. This proposal launched two new opcodes: AUTH and AUTHCALL. AUTH permits EOAs to authorize particular good contracts to behave on their behalf, whereas AUTHCALL permits these approved good 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 person, thereby bettering the person expertise. Moreover, customers may mix a number of transactions right into a single one, decreasing 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 Considerations
The delegation course of raised safety points. Malicious good contracts, if approved, may probably drain person funds.
Laborious Fork Requirement
Implementing EIP-3074 required a tough fork, a serious community improve that may be disruptive.
Restricted Compatibility
EIP-3074 didn’t combine properly with the rising ERC-4337 customary for good contract wallets.
Peoples Response on this
The Ethereum group has responded favorably to EIP-7702. Many view it as a necessary development for broader adoption of good contract wallets, offering enhanced safety and elevated performance. Moreover, some spotlight its potential for higher interoperability with different blockchains, because of its compatibility with the ERC-4337 customary. 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 presents a promising future, there are a number of issues for its adoption:
Neighborhood Consensus
The Ethereum group should attain an settlement on implementing EIP-7702, which can contain discussions, testing, and doable revisions to the proposal.
Pockets Supplier Integration
Pockets suppliers, similar to MetaMask, might want to replace their software program to help EIP-7702 transactions, which is essential for person adoption.
Good Contract Safety
The safety of the good contract code utilized in EIP-7702 transactions is important. 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 way in which for superior account abstraction sooner or later.
