Ethereum Upgrade Helped Limit Part of Binance Loss
The attack used 50 valid signatures from Binance’s own wallet; EIP-7702 also shows how smart contract features can bring new risks.
Key Takeaways
- An Ethereum upgrade from 2025, based on the available information, helped limit part of Binance’s $6 billion loss.
- The attacker used 50 signatures from Binance’s own wallet, pointing to abuse of access or authorization.
- After the news, Bitcoin fell below $79,000, while Binance took a reputational hit from the attack.
An Ethereum upgrade from 2025, according to the available information, helped siphon off part of Binance’s $6 billion (€5.4 billion) loss. The attacker used 50 signatures from Binance’s own wallet. That shows how vulnerable large crypto wallets can be when access or authorization is abused.
What EIP-7702 Made Possible
The upgrade in question is EIP-7702. That change makes regular wallets smarter by letting them run smart contract code. In practice, that gives a wallet more functions than just storing and sending crypto. Those extra capabilities can also be abused by attackers if they gain access to valid authorizations.
The attack fits into a broader pattern where large crypto exchanges and their wallets remain an attractive target. Binance was not the only party to face major security incidents before, and the industry has long seen attackers increasingly look for weak spots in wallet management and approval processes. A previous attack on reserve wallets also showed how quickly an incident at Binance can spill over into the broader debate about wallet security.
Why This Matters for the Market
The hack came alongside fresh concerns about the security of major trading platforms. The North Korean Lazarus Group had previously been linked to major crypto thefts, including the 2025 attack on Bybit. Incidents like these keep the focus on crypto exchange security sharp, especially when large sums are involved.
The crypto market itself can also feel the impact of an incident like this in sentiment. After the news, Bitcoin fell below $79,000 (€71,000), showing that investors react quickly to signals about safety and trust at major players in the sector.
Binance Remains Under Pressure
For Binance, the damage is not just financial, but also reputational. An attack that uses signatures from its own wallet directly hits trust in how an exchange protects access and authorization. That makes this incident relevant for anyone following the security of the broader crypto market.
