# Flux

Flux is a decentralized borrowing protocol that allows users to deposit various collateral types and mint the stablecoin **fUSD**.

It serves three main purposes:

* Existence of the decentralized stablecoin **fUSD**
* Borrowing of **fUSD** through **Flux Generators**
* Generating yield when depositing **fUSD** into **Flux Reservoirs**

Flux is the spiritual successor to the STAB Protocol, greatly improving upon it. It is heavily inspired by Liquity V2, and allows users to choose **their own interest rate**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ilikeitstable.com/introduction/protocol-overview/flux.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
