Omnichain Lending & Borrowing
PrimeFi lets you open a borrow on one network and receive the borrowed asset on another, without manual bridging. Under the hood, PrimeFi uses LayerZero messaging and Stargate liquidity:
Accounting stays on the origin chain (your collateral, debt, interest accrual, health factor, and potential liquidation live there).
Delivery happens on the destination chain (the asset you borrow is sent to your wallet on the target network via Stargate).
This design removes cross-chain friction while keeping a single, consistent risk model (prices, LTVs, liquidations) anchored to the origin chain.
Key properties
One position, many networks: supply collateral on chain A, receive the loan on chain B.
Origin-anchored risk: health factor, interest, and liquidation live on the origin chain where you opened the position.
Bridging handled for you: the borrowed asset is bridged by Stargate to the destination chain, no manual bridge or wallet hop needed.
Unified pricing: Chainlink price feeds drive LTV and HF on the origin chain.
Omnichain incentives: actions from any network are synchronized to Base (PrimeFi’s incentives home chain) so rewards remain consistent.
Repay on the origin network
Repay on origin: send USDC on HyperEVM and call
repay().
Interest and HF always update on the origin.
Liquidations
If your health factor falls below 1, a liquidator acts on the origin chain:
Seizure and close-out occur only on the origin against your posted collateral.
The physical location of the borrowed asset (e.g., Base) is irrelevant to liquidation logic.
This keeps the risk model simple and predictable.
Fees & gas
Protocol fees/interest: accrue on the origin chain.
Cross-chain fees: the borrow transaction includes LayerZero and Stargate fees (quoted pre-trade).
Omnichain Gas Deposit: used for incentive synchronization when you act on non-Base networks (not required to execute the borrow itself).
Claims: lender rewards are claimable weekly from any network; pLP claims after vesting execute on Base and need a small amount of ETH on Base.
Safeguards & parameters
Slippage protection:
minAmountOutanddeadlineguard the Stargate leg on delivery.Idempotency & retries: cross-chain messages are nonce-tracked and retryable if a destination step temporarily fails.
Rate limits & caps: per-asset daily borrow caps and per-route limits can be enforced.
Pause per market: individual assets/paths can be paused if volatility or oracle anomalies are detected.
Oracles: Chainlink price feeds secure LTV and HF on the origin.
What changes versus a classic bridge?
You do not manually bridge assets or manage two legs.
Borrow is one action on the origin; PrimeFi handles delivery.
Risk, rates, and liquidation remain coherent and local to the origin chain.
