Bunni DEX Shuts Down After $8.4M Exploit

The Bunni DEX team confirmed in a statement on X that the platform is permanently shutting down due to a complete lack of funds following the September exploit. The team explicitly stated that restarting operations would require ‘six to seven figures in audit and monitoring expenses alone,’ capital they simply don’t possess. Beyond the immediate security costs, the team calculated that it would take ‘months of development and business development effort just to get Bunni back to where it was before the exploit,’ an investment they cannot afford given their current financial position.

This financial reality forced the difficult decision to shutter operations entirely, making Bunni the second major crypto project to collapse this week following Kadena’s bankruptcy announcement. The simultaneous failures highlight the precarious financial position many DeFi projects face when confronted with security breaches, where the costs of recovery often exceed available resources.

The Ethereum-based decentralized exchange suffered a critical security breach in September when one of its smart contracts was compromised. According to available blockchain data, the attackers specifically targeted the platform’s stablecoin vaults, funneling over $2.3 million worth of crypto assets through various DeFi protocols. The sophisticated attack saw hackers converting stolen assets into ETH and other stablecoins to obscure the trail.

While the Bunni team responded by deactivating all active smart contracts once they detected the breach, the damage was already substantial. In the hours following the initial detection, hackers continued swapping the stolen funds through DeFi protocols, demonstrating the challenges of containing such exploits in real-time. The total loss eventually reached $8.4 million, a devastating blow to the project’s treasury and operational viability.

Despite the shutdown, the Bunni team has implemented measures to protect remaining user assets. Users can still withdraw their assets through the protocol’s website until further notice, and the team plans to distribute treasury assets to holders of BUNNI, LIT, and veBUNNI tokens based on a blockchain snapshot. The team emphasized that ‘team members will be excluded from the snapshot’ to ensure fair distribution to the community.

The validation of the legal process is currently ongoing, with exact distribution details to be shared once the legal framework is finalized. The team also confirmed they will cooperate with law enforcement agencies to recover the stolen assets. In a positive development for the affected community, security firm FailSafe offered to assist the platform to keep its operations going, though it remains unclear if this intervention came too late to alter the shutdown decision.

In a significant move for the broader DeFi ecosystem, the Bunni team has relicensed its v2 smart contracts from the restrictive Business Source License (BUSL) to the more permissive MIT license. This strategic decision enables the entire DeFi community to reuse and build upon Bunni’s technological innovations, including Liquidity-Directed Fees (LDFs), surge fees, and autonomous rebalancing mechanisms.

The team expressed pride in their technological contributions, stating ‘We have pushed the AMM space forward by a generation, and it would be a shame if our efforts went to waste.’ This open-source approach ensures that Bunni’s advanced automated market maker technologies will continue to benefit the DeFi space despite the project’s closure. The team concluded by thanking ‘everyone who has supported us throughout our journey to push DeFi forward,’ acknowledging the community that supported their innovation efforts.

The Bunni shutdown occurred alongside Kadena’s bankruptcy announcement, creating a concerning pattern of project failures within the same week. Kadena revealed it was ‘no longer able to continue operations’ and immediately stopped all activities and maintenance on its blockchain platform, citing ‘deteriorating market conditions’ as the primary cause.

These simultaneous collapses underscore the challenging environment facing crypto projects, where security vulnerabilities combined with market pressures can quickly overwhelm even established platforms. The events highlight the critical importance of robust security audits and sufficient treasury reserves for DeFi projects operating in an increasingly complex and risky landscape.
