What is EIP-7702? The Ethereum Upgrade Behind the $6.4B Binance Hack
什么是 EIP-7702？64 亿美元 Binance 黑客事件背后的以太坊升级
EIP-7702 gives ordinary Ethereum wallets smart-contract powers, but the Binance hack shows users must weigh batched, sponsored transactions against a widened attack surface.
Judgment
Ethereum wallet users and wallet providers must decide whether to enable EIP-7702 delegation, trading batched and sponsored transactions for a wider attack surface tied to the $6.4B Binance hack.
Basis
Decrypt's explainer says EIP-7702 was activated in May 2025 and lets standard Ethereum wallets temporarily take on smart-contract abilities. That enables batched transactions and gas sponsorship: a wallet can execute contract-style logic and let a third party cover fees. The same explainer's headline ties the upgrade to the $6.4B Binance hack, so the practical tradeoff is convenience and new transaction patterns versus a broader contract-like attack surface for ordinary wallets.
Unclear The source does not specify how the $6.4B Binance hack actually exploited EIP-7702, nor which wallet or contract details were involved.
Next Watch whether major Ethereum wallets publish EIP-7702 delegation controls—such as allowlists, revocation, or sponsorship limits—and whether Binance releases a postmortem naming the exploited mechanism.
