EIP-3074 is an Ethereum Improvement Proposal (EIP) that introduces a novel approach to account management. It enables the delegation of control over regular user accounts (EOA) to smart contracts, facilitating more sophisticated transaction strategies. Proposed in 2020 by Ethereum core developers, EIP-3074 introduces two new opcodes, "AUTH" and "AUTHCALL," empowering EOAs to transform into smart contracts without the need to deploy new contracts. The implementation of EIP-3074 aims to enhance the overall user experience for wallet users by enabling gas sponsorship, batch transactions, and wallet asset recovery. While EIP-3074 presents promising advancements, it also raises some concerns such as increasing the risk of user asset theft, and possibly forming a parallel technology stack with the Account Abstraction (AA) proposal EIP-4337, which requires ensuring interoperability between the two.
