Bunni Review: Why You Should Avoid This DEX

Bunni was a decentralized exchange, and its listed chain coverage included Ethereum, Arbitrum, Optimism, Polygon, Base and Unichain. DEXes generally let users swap tokens or supply liquidity through smart contracts rather than placing trades with a central exchange. But Bunni announced that it was shutting down on October 22, 2025, so those former capabilities are not a reason to use it today. The announcement followed an exploit reported at about $8.4 million. Don’t assume a surviving app, token page or old contract is still supported. Bunni’s present trading and liquidity functions should be treated as unavailable unless the project publishes verifiable, official instructions for a specific remaining action.

There is no reliable current fee schedule to use for a Bunni trade, and the exchange’s shutdown means you should not estimate costs from old interface details. On a functioning DEX, a swap can involve a protocol fee, a price impact from the available liquidity and a network transaction fee. Providing or removing liquidity can also involve transaction costs and exposure to changes in token prices. Those general DEX costs do not establish what Bunni charged. More importantly, sending a transaction to an old contract can cost gas without producing a successful or recoverable action. Don’t deposit funds to test whether Bunni still works, and don’t rely on historical fee claims as a guide to any current service.

The key trust issue is the reported exploit: about $8.4 million was lost in an incident affecting Ethereum and Unichain, according to reporting. Bunni subsequently cited financial constraints as it announced its shutdown. That history makes it especially important not to treat old smart contracts, liquidity pools or interface copies as safe or maintained. Current audit, licence, custody and support details are not established, and a past audit—if one existed—would not prove that affected contracts are safe today. A DEX normally leaves users interacting with smart contracts rather than a bank-like custodian, but that general model does not confirm where any Bunni funds now sit or whether they can be recovered. If you have an outstanding position, look for official, verifiable withdrawal guidance and avoid signing unfamiliar transactions.

Bunni’s listed networks were Ethereum, Arbitrum, Optimism, Polygon, Base and Unichain. That describes its historical reach, not a guarantee that its app or contracts are currently usable on those networks. The homepage is unavailable, and there is no established current onboarding, wallet support, mobile experience or transaction speed to recommend. Don’t connect a wallet to a site using the Bunni name unless you can independently establish that it is an official, current service; lookalike interfaces can imitate inactive projects. The token identity also needs care: the project classification names LIT, while search results show a BUNNI ticker. A ticker alone is not proof of a token’s connection to the DEX. Confirm the exact contract and network from trustworthy project communications before considering any token interaction.

The decisive limitation is that Bunni has shut down, so it is not a suitable choice for routine swaps, liquidity provision or a first DEX experience. Its reported exploit and the uncertainty around any remaining contracts add risks beyond the ordinary price and smart-contract risks of decentralized trading. There is no current fee schedule, supported-wallet list, customer-support route or recovery process established here for users to rely on. If you already used Bunni, don’t send more assets to an old pool or approve a new transaction simply because a page or token listing remains visible. Verify any withdrawal or claim instructions through official communications and check transaction details carefully. If no verifiable instructions exist, consider getting help from a qualified security professional before signing anything.
