Introducing

Welcome to PrimeFi, the omnichain lending and borrowing DeFi protocol.

Created with your assets in mind, PrimeFi is the omnichain platform that streamlines borrowing and lending with the most competitive terms in DeFi. Powered by LayerZero, your assets move natively across chains — no bridges, no extra risk.

Prime Numbers Labs has launched PrimeFi, the first omnichain lending and borrowing protocol on Hyperliquid EVM, and operates additional markets on Base and XDC.

Why PrimeFi?

Advantage	What it means for you
True Omnichain	Operates natively on Base, HyperEVM and XDC, with more chains coming soon.
Deposit ≠ Loan	Use your collateral where you hold it and receive liquidity where you need it.
Proven Security	Audited smart contracts and LayerZero architecture provide secure cross-chain messaging.
PRFI Rewards	Earn $PRFI tokens by providing liquidity, participating in liquidations, or holding NFTs from the PrimeFi collection.
PRFI NFT Staking	Stake $PRFI inside NFTs on Base to earn a share of a monthly reward pool, weighted by rarity and level. See PRFI NFTs.
Prime Numbers Ecosystem	Direct synergies with PrimeStaking and PrimePort that multiply returns.

Two protocol versions in the app

Inside the PrimeFi app you'll see a v2 / v3 toggle in the header:

• v2 — PrimeFi (Base, HyperEVM, XDC). The full omnichain lending experience with pLP boosts, PRFI emissions and cross-chain borrows. Most of this documentation describes v2.

• v3 — Fathom Lending (XDC only). A third-party Aave v3 fork operated by Fathom Protocol, surfaced inside the PrimeFi UI as a convenience. PrimeFi does not operate these contracts — for help with Fathom positions, see the Fathom Lending documentation.

See the Fathom v3 (XDC) page for the full explanation of the v3 toggle.
