- Curve Finance experienced a major security breach, losing millions.
- Trading of Curve Finance’s token has been temporarily halted.
- Ethical Hackers managed to recover a portion of the funds.
Curve Finance, a widely used decentralized finance platform, was targeted in a devastating cyber attack that sent shockwaves through the DeFi community. The attack, which came to light in the early hours of Sunday, July 30th, left Curve Finance users reeling as several stable pools were infiltrated and exploited by malicious actors.
The severity of the breach saw trading of Curve Finance’s token halted on multiple exchanges, as concerns mounted over the safety of users’ funds.
What Happened to Curve?
The attackers managed to breach Curve Finance’s security measures using a re-entrancy bug in the programming language used for smart contracts—Vyper. A re-entrancy bug allows hackers to interrupt and compromise a smart contract before it is executed to steal assets.

Vyper subsequently made an official statement on Twitter, confirming that versions including 0.2.15, 0.2.16, and 0.3.0 were affected and vulnerable. Curve Finance acknowledged the severity of the situation and stated that an investigation is currently underway to assess the extent of the hack, which has led to major losses for both the platform and its users.
This sabotage provided the attackers with unauthorized access to sensitive data and assets, draining over $42 million from the swap pool and putting as much as $100 million at risk, according to research done by CoinDesk. The Curve Finance platform and the larger DeFi community have both been significantly impacted by the news of the attack.
The value of CRV, Curve Finance’s native token, significantly dropped in the immediate wake of the breach, with a heavy price drop of 13% in less than 24 hours. This decline could indicate the waning of investor trust and cast doubt on the resilience of DeFi platforms in the face of cyber threats.
Community Response
But there is a bright spot amidst the chaos. According to a tweet by PeckShieldAlert, an ethical hacker has managed to recover a total of 2,879 ETH worth around $5.4 million of the drained assets to the Curve deployer, offering a ray of hope in the aftermath of the breach.

As expected, there were immediate reactions from platform users, investors, and enthusiasts alike. In a Twitter thread, Vyper contributor “fubuloubu” expressed concerns that the attack may have been planned.
Fubuloubu opined that such a hack would have required deep research into the protocol’s version history and the changes made therein to find an exploit. Regardless, users believe this is not the end for Vyper or Curve.
On the Flipside
- The market has remained largely unaffected following the hack. Leading cryptocurrencies Bitcoin and Ethereum have only witnessed a decline of 0.53% and 0.59%, respectively, over the last 24 hours.
Why This Matters
The incident raised broader questions about the security practices of DeFi protocols as a whole. As the DeFi ecosystem continues to grow, attracting more users and funds, the need for robust security measures becomes paramount.
