According to Wu, Ethereum founder Vitalik proposed Ethereum Improvement Proposal (EIP) 7702, which aims to optimize Ethereum's account abstraction function. This proposal allows externally owned accounts (EOA) to temporarily act as smart contract wallets during transactions and restore their original state after the transaction is completed. In addition, EIP-7702 also proposes a new transaction type that contains contract code and signature fields. These functions are similar to the batch and sponsored transactions proposed by EIP-3074.
