Gnosis Launches Hard Fork to Recover Funds After Balancer Exploit

Gnosis Chain Executes Hard Fork to Recover Funds from $116 Million Balancer Exploit

In a decisive move to address a significant security breach, Gnosis Chain has implemented a hard fork aimed at recovering assets lost in a $116 million exploit targeting Balancer. The event marks a notable effort by the community and developers to mitigate the impact of one of the largest DeFi hacks in recent history.

Following a community notice on X (formerly Twitter), Gnosis announced that the hard fork was executed on Monday after a majority of validators had already adopted a soft fork in November. The initial soft fork was enacted in response to the exploit that compromised “Balancer-managed contracts on Gnosis Chain,” which led to the unauthorized transfer of millions of dollars worth of digital assets. The recent hard fork appears to have successfully placed some of these stolen funds “out of the hacker’s control,” indicating a partial recovery of assets.

“Discussions are ongoing on how users will be able to claim back their funds, as well as how contributors involved in the rescue efforts may be recognized or compensated,” stated Philippe Schommers, Gnosis’ head of infrastructure, in a Dec. 12 forum post. “Our immediate focus is on enabling the safe recovery of funds by Christmas. Once secured in a DAO-controlled wallet, we will address the next steps.”

On Nov. 3, Balancer disclosed that hackers exploited its platform for more than $116 million through a sophisticated attack on its decentralized exchange and automated market maker. Onchain data revealed that the hacker transferred a significant amount of staked Ether to a newly created wallet. Although white hat hackers recovered approximately $28 million of the stolen assets, the majority remain unaccounted for.

Despite rigorous security audits—11 in total conducted by four different firms—the breach occurred specifically within Balancer’s V2 Composable Stable Pools. The platform’s security measures failed to prevent the exploit, raising questions about the effectiveness of these audits. Balancer responded by offering a 20% bounty to white hat hackers who helped recover some of the stolen funds, but the loss underscores the ongoing challenges in securing complex DeFi protocols.

The incident highlights the persistent vulnerabilities in DeFi infrastructure and demonstrates how community-led security measures, such as forks and bounty programs, are critical tools in defending digital assets against increasingly sophisticated threats. As Gnosis continues its recovery efforts, the broader ecosystem remains vigilant against future exploits.
