Merchant Moe Review 2026: Mantle's Liquidity Book DEX

Merchant Moe is a decentralized exchange on Mantle Network. It describes itself as the cornerstone DEX of that ecosystem, and the project is described as built by LFJ, formerly Trader Joe. Its pitch is low-cost trading, yield farming and revenue sharing for MOE stakers.

The DEX went live in early January 2024, when users could start depositing liquidity and trading. A December 2024 guide called it the largest DEX on Mantle, with about 140 million USD in TVL and roughly 20,000 USD in daily fees at that time. A later exchange listing shows a v2.2 deployment with about 16.7 million USD in total liquidity and about 140,000 USD in 24-hour spot volume. Those figures come from different dates and sources, so they should be read as snapshots.

MOE is the governance token, with a fixed supply and a decaying emission model. The project's own tagline frames Merchant Moe as a liquidity hub for Mantle, which makes it most relevant to people who already use that chain.

Merchant Moe is an automated market maker. Instead of matching buyers and sellers in an order book, traders swap against pools of tokens that liquidity providers have deposited. The price comes from the pool's pricing design, and liquidity providers earn a share of trading fees.

The platform uses Liquidity Book, a pool design that splits liquidity into discrete price bins. Liquidity providers choose where to place their funds, and trades move through the bins as the price changes. This can concentrate liquidity near the current price, which may improve trading depth, but it asks more of providers than a plain pool.

MOE is the governance token. It has a fixed supply with decaying emissions, and staking it gives holders a way to take part in protocol revenue sharing. The details of the revenue split and emission schedule are in the project's documentation.

Merchant Moe's fee schedule is not set out in the material reviewed. As with other AMMs, you should expect a swap fee that goes to liquidity providers and, in this case, partly to the protocol, plus the network gas cost on Mantle.

The exact fee for a pool is shown in the trading or pool interface before you confirm a transaction. Check it, along with price impact and slippage, before swapping or adding liquidity. How the protocol's revenue is split with MOE stakers is described in the project's own documentation.

Merchant Moe is a non-custodial DEX, so trades happen from your own wallet and the platform does not hold your funds in an account. The main risks are smart-contract bugs, token price swings, impermanent loss for liquidity providers and a possible fake-site scam. The core contracts are published on a public repository, but audit reports and details of the team's security practices are not covered in the material reviewed, so read the project's own documentation.

No incidents are mentioned in the material reviewed, and the DEX appears to be live with ongoing liquidity. Regulatory status is not stated. Depending on where you live, trading, staking or governance tokens may carry legal or tax implications, so check your local rules. Only risk money you can afford to lose.

Merchant Moe suits Mantle users who want to swap tokens, farm yield or stake MOE for revenue sharing. Liquidity providers who are comfortable managing price bins will get the most from Liquidity Book. Newcomers can use it for simple swaps, but should read about impermanent loss before providing liquidity.
