#币安神算子 The hacker used Ethereum’s EIP-7702, added last year. It lets a wallet delegate execution rights to a contract, allowing it to transfer whatever it wants. At 4:20, the hacker set up the delegation, and in under 4 minutes a single transaction swept about 2.5 billion. Add the 820 million USDC transferred from another wallet through it, and you get the 3.3 billion everyone is talking about.
