ZeroDev founder and EIP-7702 developer Derek Chiang said EIP-7702 has no vulnerability but helped the hacker in the Binance incident steal funds faster and more extensively. Chiang said the hacker transferred ETH, USDT and 62 other tokens through a single transaction. Chiang said using EIP-7702 required either obtaining the private key or deceiving Binance into signing a 7702 authorization. Chiang considered the second possibility highly unlikely but said an official postmortem was needed before that possibility could be excluded entirely.
