Ethereum EIP-7702 lets accounts run contract code, enabling features but risking permanent control by attackers.

Ethereum's EIP-7702 upgrade allows ordinary accounts to delegate execution of contract code without changing their address or keys, enabling convenient wallet features like bundled transactions and fee sponsorship. However, this delegation acts as a power of attorney, giving the contract full control over the account until revoked. A recent analysis found thousands of such delegations, including some linked to malicious contracts that can permanently drain accounts. Users should check their account's code field for the delegation marker (0xef0100) and verify the target contract to avoid losing funds. If compromised, setting up a new account and seeking help from whitehat services is advised rather than just revoking the delegation, as attackers can immediately drain any funds sent to the compromised address.
