InactiveBunni Review 2026: Uniswap v4 DEX That Shut Down After an Exploit

Our verdict on Bunni
1.5/10Bunni is a closed decentralized exchange that was built on Uniswap v4 and offered automated liquidity management. It is not a product to use now. Its main lesson is that a single exploit can end a protocol when the team lacks the capital to recover, and users should check audits and reserves before providing liquidity anywhere. The strongest point of its design was the use of a widely used exchange framework, but that framework could not prevent the losses.

What is Bunni?
Bunni was a decentralized exchange built on Uniswap v4. It aimed to maximise returns for liquidity providers through automated management of their positions and a liquidity incentive token called LIT.
The protocol shut down after an exploit in September 2025 drained about $8.4 million across Ethereum and Unichain. In an announcement in October 2025, the team said the exploit had halted growth and that it did not have the resources to recover.
Public sources describe Bunni as operating on seven chains, including Ethereum, Arbitrum, OP Mainnet, Polygon and Base. Ethereum held the largest share of its activity. The project does not give audit reports, team member names or a funding history.
How Bunni works
A decentralized exchange lets people trade tokens directly from pools of funds that other users deposit. Those depositors are called liquidity providers, and they earn a share of trading fees. Uniswap v4 added hooks, which are small pieces of custom code that can change how a pool behaves.
Bunni was built on that framework. Public sources describe it as a liquidity engine that managed positions automatically to aim for better returns for liquidity providers in changing markets. It also used a liquidity incentive token, LIT, distributed through a vetokenomics system.
Because the contracts held user funds, any flaw in their code or hooks could be exploited. That is what happened in September 2025, when the protocol lost about $8.4 million.

Pros and cons
What we like
- Built on Uniswap v4, a widely used exchange framework with a well-known hook system.
- Aimed to automate liquidity management for providers.
- Spread across several major Ethereum layer-2 networks and sidechains.
- Clear public shutdown notice, so users have a definitive status.
Watch out for
- The protocol shut down after an exploit, so it can no longer be used for new liquidity or swaps.
- The team said it lacked the capital to recover from the $8.4 million loss, so affected users have no clear path to repayment.
- The project does not show an audit report, bug bounty or insurance cover for the contracts.
- Its reliance on Uniswap v4 hooks added smart-contract complexity on top of the base exchange code.
- Public reporting includes an unrelated site, bunni.lol, that a forum user flagged as suspicious, which shows how easily impersonation sites appear.
Bunni fees
The project does not give a current fee schedule for Bunni. Since the protocol has shut down, no active trading or liquidity fees apply. Users who want historical fee data can check the protocol's past TVL and fee pages on public data trackers.
Is Bunni safe?
Bunni is shut down. Its contracts were drained in an exploit of about $8.4 million, and the team said it could not cover the losses. The project does not show a completed audit, a bug bounty, insurance or a recovery plan.
Decentralized exchanges are non-custodial in the sense that users hold their own keys, but they depend on smart contracts. A flaw in one contract can expose all deposited funds, and a shutdown does not return them automatically.
Public reporting includes a separate site, bunni.lol, that a forum user described as malware. The project does not connect that site to the Bunni protocol, so users should avoid downloads or wallet approvals from unfamiliar pages with this name.

Who Bunni is for
Bunni is no longer relevant for new users. It may be of interest to researchers, historians of DeFi failures, and anyone who still holds a position and needs to understand the shutdown.
Bunni FAQs
Is Bunni still operating?
Bunni shut down after an exploit in September 2025 drained about $8.4 million from its contracts on Ethereum and Unichain. The team announced the shutdown in October 2025 and said it lacked the capital to cover the losses. Users should treat the protocol as closed.
What was Bunni?
Public sources describe Bunni as a decentralized exchange built on Uniswap v4 that used automated liquidity management to aim for higher returns for liquidity providers. It also had a liquidity incentive token called LIT that was tied to an improved vetokenomics system. Its contracts were deployed across several chains, with Ethereum holding most of the activity.
Can I still withdraw money from Bunni?
The project does not describe a safe way to recover funds from Bunni. The team said it lacked capital to cover the exploit losses. Anyone with a position should check the project's official announcements and their own wallet records, and be wary of any message that asks for a wallet connection or a private key.
Is Bunni legal to use?
Bunni is a DeFi product, not a gambling service, so no age-based gambling rules apply to it. Anyone using DeFi should still check the legal status of crypto activity where they live. Losses from exploits can be total, so only put in what you can afford to lose.
