727 FinancePANews October 31 news, according to The Defiant, Ethereum developer nicolashw submitted a draft core EIP proposal on October 30 titled "Permanent Exit from EOA Delegation," which aims to allow key-controlled wallets to permanently disable EIP-7702 delegation, enabling account owners to reject smart contract execution at their existing addresses. The proposal number has not yet been assigned, and it remains open and unmerged; activation requires a network upgrade. The draft will use a currently invalid EIP-7702 type 4 transaction to install a non-executable three-byte marker in the account, causing future delegation authorizations to be skipped. The account will still retain its address, ordinary transfers, and contract call capabilities, but incoming calls will not execute code.
The draft points out that this feature can only block EIP-7702 delegation and cannot guard against other risks after a private key is stolen. If the private key is leaked, an attacker can still transfer funds, grant token approvals, or sign contract authorizations, and existing approvals will not be revoked. Exiting delegation may also disable recovery functions that depend on delegation, or make assets that require the old delegated code inaccessible.
