How it works?
EIP-7702 introduces a new transaction type called Type 4 transactions. This transaction type allows EOA owners to delegate their account's execution to a smart contract.
When sending a Type 4 transaction:
> The user signs an authorization message from their EOA
> The Ethereum network temporarily treats the EOA as a smart account
> Smart contract logic executes on behalf of the EOA and the delegated smart contract can then perform advanced actions such as batch transactions, gas sponsorship, session keys, delegated permissions.
