# ButtonZero User Guide

***ButtonZero*** is an overcollateralized borrowing platform created by [PRL.one](https://www.prl.one/). It offers users the ability to borrow cash (USDT), using their cryptocurrency holdings as collateral (ETH, wBTC, AMPL), at a fixed rate with **zero** coupon payments, **zero** liquidations, and **zero** margin calls. 

This pages to follow will serve as a user guide, including a how-to guide and explanation about the protocol.

Note: Terminology in fixed-income finance can trip users up. To clarify:

* The "Borrower" of a bond = Bond Seller = Bond Issuer = Debtor&#x20;
