H2 Finance V3 Review 2026: A Small Uniswap V3 Fork on Cronos zkEVM

H2 Finance V3 is a decentralized exchange on Cronos zkEVM. It is described as a Uniswap v3 fork, which means it uses concentrated-liquidity pools where users swap tokens and liquidity providers earn fees.

The project has its own token, $H2, and runs farms that pay extra rewards to liquidity providers. It has been tracked since August 2024. Total value locked is about $18,000, down roughly 7% over the past week, which makes it a very small venue.

The homepage carries little detail beyond the name, so most of what is known comes from the project's terms, farm and token documentation and third-party price pages. No audits are listed for the protocol.

H2 Finance V3 is an automated market maker. Instead of an order book, traders swap tokens against pools of funds supplied by liquidity providers. A pricing formula adjusts the rate as the pool's balance changes, so larger trades relative to pool size move the price more.

The v3 design, which this project copies, lets liquidity providers place funds within a chosen price range. This can make capital work harder near the current price, but it also means a position stops earning fees if the market moves out of its range. Providers also face impermanent loss when the relative prices of the two pool assets change.

On top of trading fees, H2 Finance runs farms. These offer extra rewards, described as additional to the fees providers already collect. The project's terms refer to two protocol versions, v2 and v3, built from open-source or source-available smart contracts.

The homepage does not publish fee tiers. As a Uniswap v3 fork, swap fees are normally set per pool and paid to liquidity providers, but the exact tiers here are not stated.

Users will see the pool fee and estimated price impact in the swap interface before they sign. Network gas costs on Cronos zkEVM apply on top. Farm reward rates are shown on the farms page, not.

No security audits are listed for H2 Finance V3. Because it is a fork of widely used code, the core logic may be familiar, but forks can still carry deployment or configuration errors, and the project does not publish audit reports. Users keep custody of their funds in their own wallets, but deposits into pools and farms are exposed to smart-contract risk.

Liquidity is very thin, so large trades can face heavy slippage and liquidity providers can find it hard to exit without moving prices. Anyone considering it should check the contract addresses against the project's documentation and start small. The project does not publish team details or regulatory status. Check the rules for DeFi use in your own jurisdiction.

This is for experienced DeFi users who already use Cronos zkEVM or want to try a small Uniswap v3-style exchange and farms. It is a poor fit for beginners, anyone moving large amounts, or people who need audited, deeply liquid venues.
