# Borrow

> Pull reserve cash into the margin vault and open a debt-share position.

## Steps

1. Deposit recognized collateral first (or use deposit-and-borrow).
2. Choose the borrow asset and amount.
3. Review health after borrow. The app refuses a preview that would land at or below 1.1.
4. Confirm. `user_open_debt_position` runs once per (margin, reserve); later borrows reuse it.

Borrowed tokens land in the **same margin vault**. They can be swapped, supplied to Kamino, or held. They are not withdrawn to the wallet unless you transfer them out.

## What limits a borrow

* Post-borrow health must stay **> 1.1**
* Asset `borrow_enabled` and reserve status
* Reserve cash and borrow cap
* `max_assets_per_margin` (24)
* Operating mode (borrow pause / halt)
