Ethereum’s EIP-7702 lets ordinary wallets group steps such as token approvals and swaps, while moving assets through a delegation still requires access to the account’s private key or signed authorization.
A wallet can put permission for a token to be spent and its swap into one operation, rather than sending each step separately. EIP-7702 covers externally owned accounts (EOAs), Ethereum wallets controlled by a private key. Ethereum added the standard in its 2025 Pectra upgrade, allowing an EOA to authorize code to act through the account and giving a regular wallet some smart-contract functions.
Derek Chiang, founder of wallet developer ZeroDev, said the security question is how an attacker could obtain the authorization needed to use a delegation.
A Binance hot-wallet incident illustrated how bundled transfers can work: one operation moved Ether (ETH) along with funds held in 63 tokens, as covered in EconoTimes’ earlier report. Each account’s nonce sets the order of its transactions; Chiang said grouping the balances kept individual token transfers from vying with Binance withdrawals for those sequence numbers, and some separate transfers might have failed during the activity.
Binance said its initial inquiry had not identified a compromise of the hot wallet’s private key. Chiang also pointed to EIP-8141 as a draft that might add rules to transaction approval. His example was a second-signer requirement for transfers above 1,000 ETH. The proposal remains in draft form.
