Interpreting Vitalik’s latest proposal EIP-7702: The ultimate prescription for account abstraction?

1. EIP-7702 is a new proposal by Vitalik Buterin to improve Ethereum's account abstraction and make it more efficient and secure.
2. The implementation of EIP-7702 requires the understanding of three other proposals: EIP-4337, EIP-3074, and EIP-5003, which have the common goal of improving the account system on Ethereum.
3. EIP-4337 allows smart contracts to execute transactions like accounts, improving the user experience, but most smart contract accounts are still controlled by a single EOA.
4. EIP-7702 proposes a new transaction type that accepts both contract_code and signature fields, implements the temporary delegation function of EOA to smart contracts, and is highly compatible with EIP-4337.
5. Through EIP-7702, users' existing EOAs can execute any smart contract code, which may completely change the way we interact with Web3 applications in the future.
