# Flash Loan

The flash loan operation will allow users to borrow from reserves in a single transaction, as long as the user returns more of the liquidity that has been tied up.

The Keep protocol  implements a solution that can use Flash Loans in combination with any other features of the protocol, thus powering many new possibilities:

* Collateral trading. Change the risk from one or more collateral to another without closing the debt position.
* Repay a loan with the collateral. Use the collateral deposit in the protocol to pay down debt positions.
* Margin trading. Create margin positions that can be traded later.
* Debt swaps. Change the risk of debt from one asset to another.
* Margin deposits
