LunarBase Review 2026: Prop AMM Priced Offchain, Settled Onchain

LunarBase describes itself as an onchain pool, priced offchain from the real market. It is a proactive market maker, often called a prop AMM, and the homepage says it is live on Base and BNB Chain, with Arbitrum and Robinhood Chain listed as next. Third-party tracking also lists a Monad deployment.

Most trading reaches it through aggregators and wallets rather than a dedicated trading app. The homepage names 1inch, 0x, KyberSwap, OpenOcean, Rango, LI.FI, deBridge, Across, Relay and others, plus wallets like MetaMask and Trust Wallet. It reports about $399M traded to date and a 30-day average of $2.3M a day. These are self-reported figures.

Pool depth is modest. Tracked total value locked is roughly $117K, and the project was listed on trackers from 31 March 2026. There is no token. YZi Labs is named as a backer. Roadmap items include around-the-clock quotes for tokenized stocks and an AI quoting model that currently runs only in a sandbox.

A normal AMM sets prices from a formula and the ratio of tokens in the pool, so prices lag the wider market until arbitrageurs correct them. LunarBase uses a different approach. It keeps an onchain pool but updates its quotes from an offchain pricing engine that follows the real market. The project says this produces tighter spreads for traders.

Swaps still execute onchain. Most volume arrives through aggregators and wallets that compare many venues and send an order to whichever gives the best price. LunarBase lists more than 20 such venues, including 1inch, 0x, KyberSwap and CoW Swap via solvers. A trader does not need to visit a LunarBase site to use it.

Liquidity providers are described as inventory providers who allocate capital on Base by arrangement. The project says they are paid in spread, not emissions. Because the quoting logic sits offchain, the quality of prices depends on the operator's model. The project is also testing an AI quoting model in a sandbox, though none of its quotes are executed.

The project does not publish a protocol fee table on its homepage. It says liquidity is paid in spread, not emissions, which means the cost of a trade is built into the quoted price.

For BNB/USDT, the project reports a time-weighted spread of 2.2 basis points over 28 September to 4 October. Traders also pay network gas, and any fee charged by the aggregator or wallet they route through. Users would see the final price and costs in the aggregator quote before signing.

No audits are listed for LunarBase in the tracking data, and the homepage does not point to an audit report. Contract addresses and ABIs are on GitHub, so the code can be inspected, but that is not a substitute for an independent review. The project names an investor, YZi Labs, but does not publish team names on the homepage.

The main risks are smart-contract risk, reliance on an offchain pricing system, and thin liquidity. If the quoting engine misprices or goes offline, the pool could trade at poor prices or be exploited. Swaps are non-custodial in the sense that users sign onchain transactions, but inventory providers allocate capital by arrangement and should assess counterparty terms. No incidents are described in the material reviewed. Treat balances as at risk and size trades accordingly.

LunarBase fits DeFi traders who swap through aggregators on Base or BNB Chain and care about spread. It also suits wallet and aggregator teams looking for an integration, and market makers interested in allocating inventory. Users who need audited contracts, deep liquidity or a native token should look elsewhere or wait for more information.
