The team behind voltz define it as

Now let’s break that down
<aside> 💡 Simply put, voltz is a de-fi protocol that allows you to trade a financial instrument called interest rate swaps.
</aside>
What interest rate swaps allow you to do is basically swap a [floating interest rate](https://www.investopedia.com/terms/f/floatinginterestrate.asp#:~:text=freelancers%2C and individuals.-,What Is a Floating Interest Rate%3F,or with general market conditions.) for a fixed interest rate and vice versa. The person with the floating interest rate doesn’t want the volatility associated with the variable interest rate. The person who’s getting the floating interest rate payment looks to make a profit when the floating interest rate decreases.

One side is called as Fixed Takers (FTs), where you swap a variable rate and end up with a fixed rate of return. This provides traders with the ability to de-risk their portfolio by ‘locking in’ a fixed interest rate.
For example, you may own an asset that has a variable rate of return, such as cDAI. If you don’t want the uncertainty of a variable interest rate on your DAI, but instead would like a fixed rate of return, you can initiate a swap on Voltz.
Let’s illustrate this with an example:
