EIP-7702 lets regular Ethereum wallets execute smart contract code without moving funds to a new address, enabling features such as transaction batching and sponsored fees. But unlike a token approval, a delegation can grant a contract control over the logic of an entire account. Following the October 2026 Binance hot wallet drain, this guide explains how EIP-7702 works, why valid signatures matter, and how to check and revoke unfamiliar delegations through Etherscan and your wallet. No flaw in the Ethereum feature itself had been reported as of October 30, 2026.
