Bunni DEX to Shut Down Following $2.3M September Exploit

Bunni’s closure after a multi-million dollar exploit underscores persistent security issues in DeFi, with remaining assets to be distributed and smart contracts open-sourced for public use.

Fact Check
The statement makes two primary claims: 1) Bunni DEX was exploited for $2.3 million, and 2) it is shutting down as a result. The first claim is overwhelmingly supported by the evidence. Multiple credible sources, including Yahoo Finance (Source 1), crypto.news (Source 4), CoinCentral (Source 6), GetFailsafe (Source 7), and altfins.com (Source 9), all consistently report that Bunni DEX suffered a smart contract exploit resulting in a loss of approximately $2.3 million. The second claim, regarding the shutdown, is strongly supported by the most authoritative and relevant source provided. The Yahoo Finance article (Source 1) explicitly states that "Bunni DEX halted its smart contracts following an exploit." For a decentralized exchange, halting smart contracts is a critical operational stoppage, functionally equivalent to shutting down its core services. This source directly links the halt (the shutdown) to the exploit, establishing the causal relationship asserted in the statement. While several other sources confirm the hack, they are silent on the operational status of the DEX. This is an absence of corroborating evidence, not a contradiction. No source claims that Bunni DEX continued to operate normally after the exploit. Therefore, based on the strong, direct evidence from a high-authority source, the statement is assessed as likely true with a high degree of confidence.
Summary

Bunni, a decentralized exchange built on Uniswap v4, announced its permanent shutdown after an $8.4 million exploit in September depleted resources needed for recovery. The attack targeted the BunniHub smart-contract system across Ethereum and Unichain. The team stated that relaunch costs for audits, monitoring, and development would run into six to seven figures, which it cannot afford. Withdrawals remain open, and remaining treasury funds will be distributed to BUNNI, LIT, and veBUNNI holders, excluding the team, pending legal compliance. Bunni has open-sourced its v2 smart contracts under the MIT license and will continue working with law enforcement to pursue the exploiter.
