Bunni DEX Ceases Operations After $8.4M Hack

Bunni DEX officially shut down after an $8.4 million hack in September 2025, citing unaffordable relaunch costs and a complete operational capital loss, announced via their X account.

The closure of Bunni DEX highlights vulnerabilities in the DeFi sector, with $3.1 billion in hacks by October 2025, shaking investor confidence and impacting liquidity providers.

The sudden shutdown of Bunni DEX follows a crippling $8.4 million exploit in September 2025. The team announced the closure, citing unaffordable costs for a secure relaunch and the complete loss of operational capital.

The Bunni team is collectively responsible, operating under their official X account. They stated that significant auditing and monitoring expenses have halted potential recovery efforts, rendering the relaunch financially impossible.

The closure’s direct impact includes a total value locked collapse, significantly affecting users reliant on Bunni DEX. It also resulted in a treasury depletion, limiting options for reimbursing affected parties.

Without external funding or rescue, and stolen assets laundered via Tornado Cash , the protocol faces severe financial constraints, affecting its ability to resume operations or compensate stakeholders effectively.

This event aligns with several high-profile DeFi protocol closures due to similar smart contract exploits. The industry recorded losses exceeding $3.1 billion by October 2025, reflecting vulnerabilities in decentralized finance systems.

The technological and regulatory outcomes remain uncertain, with reliance on community-driven solutions as intellectual property becomes open-source. This transition could foster innovation under the MIT license, but effective security measures are essential.
