On August 7, Curve Finance, a prominent player in the decentralized finance (DeFi) landscape, made a significant announcement. The protocol has put forth a $1.85 million bounty to apprehend the hacker responsible for a major security breach.
This move comes after an exploit that saw over $61 million drained from Curve Finance’s pools on July 30. The exploit targeted several stable pools on Curve Finance, leading to a ripple effect across the DeFi ecosystem.
#PeckShieldAlert A total of ~$73.5M worth of cryptos on #Ethereum were stolen in the #Curve Reentrancy exploit. So far, ~73% of them (~$52.3M) have been returned.

The attacker exploited a reentrancy vulnerability in the Vyper programming language, causing significant losses for multiple DeFi projects. This incident has exposed vulnerabilities across DeFi projects and ignited a race to recover the stolen funds.
The aftermath and the community’s response
The fallout from the attack sent shockwaves through the crypto world. All Wrapped Ether (WETH) pools may be vulnerable to attack due to this flaw. In addition, the exploit resulted in a reward block with an MEV of 584.05 Ether, making it one of the biggest MEV rewards ever.
As a result of the crisis, the DeFi group came together to support Curve Finance. In all, 2,879 ETH (around $5.4 million) were recovered from the exploiter and returned to Curve Finance by white hat hackers.
Initial Bounty and the Hacker’s Response
On August 3, Curve, Metronome, and Alchemix launched a cooperative effort to retrieve the missing cash. They offered a 10% reward in exchange for the return of the remaining 90% of the stolen money. This offer includes the promise of no additional legal action or law enforcement participation.
We are extremely happy to announce that all funds stolen by the hacker of the Alchemix @CurveFinance pool have now been returned.
Full post mortem coming.

In a surprising turn of events, the original attacker accepted the bounty offer and began returning the stolen funds on August 4. The hacker returned funds to Alchemix and JPEGd but did not complete refunds to other affected pools.
The extended bounty
As the deadline for the voluntary return of funds passed, Curve Finance decided to extend the bounty to the public. The protocol now offers a reward valued at 10% of the remaining exploited funds, currently standing at $1.85 million, to the person who can identify the exploiter in a way that leads to a conviction in the courts.

This move by Curve Finance underscores the seriousness of the situation and the lengths the protocol is willing to go to ensure justice. It’s a call to arms for the DeFi community, highlighting the need for collective action to safeguard the integrity of the ecosystem.
The road ahead for the DeFi community
The Curve Finance exploit has been a stark reminder of the risks inherent in the rapidly evolving world of decentralized finance. As the hunt for the hacker continues, the DeFi community watches with bated breath, hoping for a resolution that reinforces trust and security in the ecosystem.
The incident has also sparked a broader conversation about the need for robust security measures in DeFi protocols. It has highlighted the importance of continuous security audits, using secure programming languages, and implementing effective reentrancy guards.
The extended bounty offer by Curve Finance is a testament to the protocol’s commitment to its users and the broader DeFi community. It sends a strong message to potential attackers about the consequences of exploiting vulnerabilities in DeFi protocols.
As the DeFi ecosystem continues to grow and evolve, incidents like the Curve Finance exploit serve as valuable lessons. They underscore the importance of security, transparency, and community collaboration in navigating the challenges and risks of the DeFi landscape.
