# Introducing

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](/rewards-and-tokens/prfi-staking-nfts.md). |
| **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](https://docs.fathom.fi/lending/deployments/xdc-network).

See the [Fathom v3 (XDC)](/v3-markets/fathom-v3.md) page for the full explanation of the v3 toggle.
