Our verdict on Koi Finance AMM
5.8/10Koi Finance AMM suits DeFi users already on zkSync Era who want swaps, farming and bonds in one place and accept small-protocol risk. Its main strength is the broad feature set on a low-cost rollup. The main caveat is the lack of listed audits and modest liquidity of about $1.2 million, so keep positions small and read the documentation first.

What is Koi Finance AMM?
Koi Finance AMM is a decentralized exchange and yield platform on zkSync Era. Its own description calls it a fast DEX, yield and bond platform, and its documentation lists swaps, liquidity pools, farming, bonds and veDAO governance.
The project has been tracked since March 2023 and holds about $1.2 million in total value locked. That puts it among smaller DEXs, with limited liquidity compared with major venues. It has its own token, KOI, and a public GitHub organization with many repositories.
The tracked data lists no audits, and the team behind the project is not named on the homepage. Those gaps matter for anyone weighing smart-contract risk.
How Koi Finance AMM works
Koi Finance AMM uses an automated market maker. Instead of matching buyers and sellers, traders swap against pools of two tokens, and the price shifts as the balance in the pool changes.
Liquidity providers deposit tokens into those pools and earn a share of trading activity. The platform also offers farming, where providers can receive additional rewards, and bonds, where the protocol offers tokens in exchange for assets or liquidity.
Governance follows a veDAO model described in the documentation, in which token holders take part in decisions about the platform. All of this runs through smart contracts on zkSync Era, so users keep custody of their funds in their own wallet.

Pros and cons
What we like
- Combines swaps, pools, farming, bonds and governance in one platform.
- Runs on zkSync Era, which offers faster, cheaper transactions than Ethereum mainnet.
- Non-custodial: users trade from their own wallet.
- Active documentation and a public GitHub organization with many repositories.
- TVL has been tracked since 2023, showing the protocol has been live for some time.
Watch out for
- TVL is about $1.2 million, so liquidity is shallow and larger trades may see noticeable slippage.
- No audits are listed in the tracked data, so smart-contract risk is unverified from public sources.
- Fee levels, team details and governance specifics are not published on the homepage.
- It depends entirely on zkSync Era, so chain-level problems or low activity there affect it directly.
- The KOI token trades at a very small price and thin volume, which makes it volatile and hard to exit in size.
- Bonds and veDAO governance add complexity that beginners may find hard to evaluate.
Koi Finance AMM fees
Fees are not published on the homepage or in the tracked data. Users would see swap fees, pool fees and any gas costs in the app when they preview a transaction.
On zkSync Era, network fees are paid in ETH and are generally lower than on Ethereum mainnet. Check the quoted price impact and fee before confirming, especially in smaller pools.
Is Koi Finance AMM safe?
No audits are listed for Koi Finance AMM in the tracked data, and the homepage does not publish audit reports or team details. Users should look for audit information in the documentation and GitHub before depositing.
As a non-custodial DEX, funds stay in your wallet until you interact with a pool or farm, but deposited funds are exposed to smart-contract bugs, impermanent loss and token price swings. Small TVL and a low-priced token increase volatility and exit risk. No hacks or incidents are stated.

Koi Finance AMM FAQs
What is Koi Finance AMM?
Koi Finance is a DeFi platform on zkSync Era that combines a DEX, liquidity pools, yield farming, bonds and veDAO-style governance. The AMM part is the swap and liquidity side of that platform.
Which blockchain does Koi Finance use?
It runs on zkSync Era, a zkRollup network that settles to Ethereum. You need a wallet that supports zkSync Era and a small amount of ETH on that network for transaction costs.
What is the KOI token used for?
KOI is the platform's own token. Documentation describes veDAO governance, which in this model usually means locking tokens to gain voting power, though the exact lock terms should be checked in the docs.
Is Koi Finance audited?
The tracked data lists no audits, and the team does not publish audit reports on its homepage. As with any small DeFi protocol, treat it as higher risk and only commit what you can afford to lose.
How much liquidity does Koi Finance have?
Total value locked is roughly $1.2 million according to DeFi tracking data, with a small weekly rise of about 2.6 percent. That is small compared with major DEXs, so slippage can be high on bigger trades.
What fees does Koi Finance charge?
Fees are not stated on the homepage. Swap fees and pool-specific fees are normally shown in the app before you confirm a trade, so check there.
