# 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**.
