# Parallel Rate Carry

> Run XLM and BLUSDC carry legs side by side in one margin account using Dual Borrow.

Borrow **XLM** and **BLUSDC** together with **Dual Borrow**, then supply each to its matching Blend pool. Both legs live in one margin account.

**1. Dual Borrow**

On **Margin → Leverage your Assets**, deposit collateral, switch to **Dual Borrow**, and pick XLM and BLUSDC. See [Borrow](https://docs.vanna.finance/stellar/guides/margin/borrow.md).

**2. Supply each leg**

On **Farm**, supply XLM to the Blend XLM pool and BLUSDC to the Blend BLUSDC pool.

**3. Monitor both spreads**

Compare each Blend supply APY with its Vanna Borrow APY. Rates, amounts and debt are tracked per asset.

**4. Exit both legs**

Withdraw each asset from Blend and repay its own loan. Then check for leftovers.

## Good to know

* **Shared risk.** The two legs share one health factor. They are not two isolated loans.
* **Several transactions.** Opening and closing take several transactions. If one fails after another confirms, check the account before retrying.
