End-to-end workflow

Scenario

You have ETH collateral on HyperEVM and want to borrow USDC on Base.

What you do (single flow)

1. In PrimeFi (still on HyperEVM), choose:

   • Borrow asset: USDC

   • Destination chain: Base

   • Amount: e.g., 5,000 USDC

2. Confirm the transaction on HyperEVM. Review the variable borrow rate, Health Factor estimate, protocol fee, and quoted Stargate/LayerZero messaging cost before signing.

What happens on-chain

1. Origin checks (HyperEVM)

   • LendingPool validates your health factor, LTV, reserve state, borrowing configuration, and available liquidity.

   • Your variable debt is minted on HyperEVM for the borrowed amount.

2. Cross-chain delivery

   • StargateBorrow deducts any configured cross-chain borrow fee.

   • It asks Stargate for the expected received amount and uses that quote as minAmountLD.

   • It quotes the native messaging fee and calls the configured Stargate router's sendToken.

3. Destination delivery (Base)

   • If messaging and destination execution succeed, Stargate delivers the quoted USDC amount to your wallet on Base.

   • Your collateral and debt remain on HyperEVM.

Result after successful delivery: you hold USDC on Base while your debt accrues on HyperEVM against your origin-chain collateral.

PrimeFi submits the Stargate delivery leg from the origin transaction. This reduces manual steps but does not guarantee delivery or remove messaging, liquidity, configuration, or destination-execution risk.
