EIP-7702 Enabled Faster Token Transfers in Binance Hack
ZeroDev founder and EIP-7702 contributor Derek Chiang said EIP-7702 itself has no vulnerability, but its transaction-batching feature helped attackers move assets during the Binance hack. The feature lets an externally owned account use a smart contract to combine actions, such as approvals and transfers, into one transaction. Chiang said the attacker moved ETH, USDT and 62 other tokens in a single transaction, avoiding the need to submit a separate transaction for each asset. This made the theft faster, although Binance’s legitimate withdrawals were competing for the wallet’s transaction nonce and could have caused some attacker transactions to fail. To use EIP-7702, the attacker would have needed either the wallet’s private key or a signed 7702 authorization. Chiang said the latter seemed unlikely, but could not be ruled out before Binance publishes its postmortem. He stressed that EIP-7702 is not itself defective, while acknowledging that its greater account capabilities can also benefit attackers.
Bearish
The report is short-term bearish for crypto market confidence because a major exchange-related theft and the use of EIP-7702 to accelerate asset transfers may prompt traders to reassess wallet security and exchange custody risks. Similar exchange hacks have often triggered immediate risk aversion, scrutiny of exchange reserves and outflows, and short-lived selling pressure, especially in assets directly involved. However, the article does not establish that EIP-7702 contains a vulnerability or explain how the attacker obtained the necessary private key or authorization. That distinction limits the case for a broad protocol-level sell-off. In the near term, price effects are likely to depend more on the stolen amount, recovery prospects, Binance’s response and any evidence of wider exposure than on EIP-7702 alone. Over the longer term, the incident could increase demand for stronger authorization controls, clearer wallet warnings and safer implementation practices. If the postmortem confirms compromised credentials rather than a protocol flaw, the impact on Ethereum and the broader market may fade; evidence of a systemic authorization weakness could prolong security concerns and weigh more heavily on sentiment.
