Perena Dex Review 2026: Solana Stablecoin AMM and USD*

Perena is a decentralized finance protocol on Solana that focuses on stablecoins. It began with Numéraire, an AMM designed for stablecoin swaps, and says it wants to act as a neutral layer that brings liquidity to stablecoin issuers. It was listed on DeFi trackers in January 2025.

The product line has since grown. Perena offers USD* (USD Star), a yield-bearing asset, along with a transparency dashboard and a Proof of Reserve feature for checking its backing. It has also launched vaults, such as a JLP Delta Neutral strategy, aimed at stable yield.

At roughly $568,000 in total value locked, it is a small protocol, and the tracked data lists no audits and no token. Its homepage is minimal, so users should rely on the in-app dashboards and documentation to understand each product. One investor write-up and press coverage describe backing and a mission to manage stablecoin liquidity and risk, but terms are not detailed here.

Perena is built around stablecoin liquidity on Solana. Its Numéraire AMM is a liquidity pool design tuned for assets that should trade near the same price. Liquidity providers deposit stablecoins into a pool, and traders swap between them for a fee. That fee goes to providers.

On top of the AMM, Perena issues USD*, a yield-bearing asset, and runs vaults that deploy deposits into strategies. One example is a JLP Delta Neutral strategy, which aims to earn yield while offsetting price exposure. Another idea discussed by the founder is tranched yield, where returns are split into different risk levels.

All of this runs through smart contracts on Solana, and users interact with them from their own wallets. Yield depends on market conditions and the underlying strategy, so it can fall or turn negative.

Swap fees, vault performance fees and any fees on USD* are not published on its homepage available for this review. Users would see the cost of a trade and any vault fee in the app at the point of transaction, and in the project's documentation.

You will also pay standard Solana network fees, which are usually small. Quoted vault yields are estimates, so check whether they are shown before or after fees.

No audits are listed for Perena in the tracked data, and the project's homepage does not publish audit reports. As with any DeFi protocol, funds are exposed to smart-contract bugs, oracle or pricing issues, and stablecoin depegs. Vault strategies add market and counterparty risk beyond the base AMM.

Perena promotes Proof of Reserve for USD*, which lets users check backing, but that is not a substitute for an independent audit. The project does not publish a licence or regulatory status. Check that using such products is permitted where you live, and never deposit more than you can afford to lose.

Perena is for Solana users who hold stablecoins and want to swap them or earn yield on them, and who understand smart-contract and strategy risk. It is less suited to people who want audited, battle-tested protocols with deep liquidity, or who need to trade large sizes.
