Binance Hack: EIP-7702 Linked to $2.5B Wallet Drain

| bitcoinist.com
The Binance hack reportedly drained about $2.5 billion from the exchange’s Binance 14 Ethereum hot wallet using Ethereum’s EIP-7702 authorization feature. The attacker prepared 50 authorization requests, and analysts say one was accepted, allowing a malicious contract to transfer funds without separate approval for each transaction. The incident was part of a broader breach estimated to have affected about $6.3 billion in assets across multiple networks. Binance’s preliminary investigation pointed to a potentially compromised DevOps engineer’s laptop and access to an internal service container. The exchange said it had found no evidence that wallet private keys were leaked. Binance temporarily restricted withdrawals and said it would cover customer losses through its SAFU fund and company reserves. Tether, Circle and other partners froze more than $2.3 billion in USDT and USDC; Binance reported about $3 billion in affected assets frozen overall. Arbitrum also moved linked assets to a restricted wallet. The Binance hack does not establish a flaw in EIP-7702 itself, but it highlights risks from delegated wallet permissions and weak internal access controls. Traders should monitor asset flows, recovery updates and withdrawal conditions. The freezes may hinder cash-outs, while further security disclosures could affect confidence in exchanges and wallet authorization tools.
Neutral
The direct price impact on ETH is likely to be limited and uncertain. The reported theft involved a Binance hot wallet and does not show that Ethereum or EIP-7702 itself was compromised. In the short term, security concerns and risk aversion could create some selling pressure on ETH, while traders assess whether the incident signals broader wallet risks. However, the freezes and the absence of evidence that private keys leaked may limit contagion concerns. Over the longer term, clearer investigation findings and stronger authorization controls could ease pressure; evidence of a protocol-level flaw or wider losses could instead weigh on sentiment. On the available information, a neutral ETH price outlook is most appropriate.
