Peridot Finance Goes Live on Stellar Mainnet

Peridot Finance launched on Stellar mainnet on May 22nd, opening lending and borrowing markets for the first time on the cross-chain money market protocol. The Peridot V2 app shipped alongside the launch, adding fiat on/off-ramps (IBAN, bank transfer, credit card), a streamlined dashboard, and split easy/expert flows. Boosted markets opened with around 10% APY from day one.

What shipped

Peridot's Hub & Spoke architecture centralizes lending logic in Soroban smart contracts on Stellar, with lightweight spoke contracts on other chains. Users deposit collateral on one chain and borrow on another without bridging tokens or juggling wallets. The mainnet release puts that architecture into production for the first time. The Soroban contracts are audited by Halborn and open source at github.com/peridotfinance/peridot-soroban.

Peridot V2 is the user-facing layer. The launch package includes:

• Boosted lending markets targeting around 10% APY at open
• Borrowing against deposited collateral, exposed through both an easy mode and an expert mode in the dashboard
• Fiat on/off-ramps wired in: IBAN, bank transfer, and credit card
• Freighter wallet integration for Stellar-native account flow

Peridot has flagged perpetuals as the next addition.

DeFindex integration

A week before mainnet, Peridot and DeFindex announced a native integration that treats DeFindex's automated USDC vault yield as collateral inside Peridot's cross-chain lending markets. USDC parked in a DeFindex vault earns vault yield and can then serve as collateral for borrowing on Peridot across chains, a composition that is new to Stellar this month.

Background

Peridot Finance received a $91,750 SCF Build award in SCF #38 for "DeFi UX & Cross-Chain Lending on Soroban." Mainnet marks the close of the funded work: the project completed its SCF tranches and shipped to production, a milestone not every SCF awardee reaches.

Why it matters

Stellar already has lending. Blend Capital and Templar Protocol are the dominant lenders on the network today: Peridot brings multi-asset cross-chain lending to Stellar mainnet, with fiat on/off-ramps integrated into the app itself. The DeFindex tie-up extends that surface: yield-bearing USDC vault positions on Stellar can serve as collateral for borrows routed to other supported chains. For end users, that means moving fiat into a yield-earning vault and then borrowing against it inside one Stellar-native app, rather than coordinating across multiple wallets, bridges, and onboarding flows.
