Flare Coston2

PrimeFi's XRP money market on the Flare Coston2 testnet (chain 114).

The Flare Coston2 market is PrimeFi's XRP lending market running on Flare's Coston2 testnet (chain 114). XRP enters the Flare ecosystem as FXRP (FAssets-minted XRP), which you supply as collateral to borrow against — without selling your XRP.

Reserves

All non-native reserves are mintable test mocks dispensed by the in-app Get test tokens button:

• FXRP — testnet stand-in for FAssets-minted XRP (your primary collateral)

• RLUSD — Ripple USD stablecoin

• stXRP — staked-XRP representation

• FBTC — wrapped BTC variant

• USDT0 — USD₮0 stablecoin

• WBTC

• WETH

On mainnet, FXRP is minted from real XRP via Flare FAssets — see How FXRP works. On Coston2 it's a mintable mock you get from the in-app faucet.

Rewards (rFLR)

Supplying and borrowing on Coston2 earns rFLR, streamed by the Aave v3 RewardsController. The app reads the live emission rate from the on-chain incentive data provider, so the reward APRs you see in the markets table and asset pages are live on-chain values, not estimates.

E-Mode

The market ships an XRP-correlated E-Mode category so XRP-pegged assets can be used together at higher capital efficiency (higher LTV / liquidation threshold) when borrowing within the correlated group.
