# What are Flash Loans?

Flash Loans are a novel concept that allows anyone to borrow any amount of funds at the beginning of a transaction without the need to deposit any collateral, as long as these funds are paid back before the same transaction is completed.

While Flash Loans have been used under the hood by DeFi Saver for a while for enabling greater leverage management or refinancing tools, the Recipe Creator now let’s anyone utilize this power for their own specific use case. 

## What you need to know:

* For technical reasons, the flash borrow action must be the first one in the recipe. 
* The available flash loan sources are:\
  \
  -> Aave\
  -> Morpho\
  -> Maker\
  -> Spark\
  -> CurveUSD<br>
* You can only have a single flash loan in a recipe. It is technically possible to loan more than one asset via Aave, but the UI does not currently support this option.

## Use-cases:

Generally speaking, flash loans can be used whenever you need a temporary loan that you know you’ll be able to pay back at the end of the transaction. Some of the potential use cases include:

* Creating a fully leveraged position
* Collateral or debt asset swaps
* Closing/unwinding a position
* Decreasing/increasing leverage within a position
