EIP-7702
An Ethereum upgrade (Pectra) letting any EOA temporarily delegate execution to a smart-contract implementation — native account abstraction without losing EOA UX.
EIP-7702 activated on Ethereum mainnet in May 2025 as part of the Pectra hard fork. It adds a new transaction type where the signer attaches a list of addresses whose code will be temporarily set on their EOA for the duration of the transaction.
The mechanism gives every existing EOA on-demand smart-contract capabilities — batched calls, paymaster gas sponsorship, custom signature schemes — without migrating to a new address. Combined with ERC-4337, EIP-7702 is the first concrete step toward native account abstraction at the protocol level.
