Getting rBTC and back to BTC with FastBTC
This guide refers to the integration of FastBTC implemented by MOC
Money On Chain has implemented an integration of FastBTC Relay developed by Sovryn.
FastBTC is a quick and easy way to obtain the rBTC you are going to need to operate the Money On Chain protocol. It lets you exchange your BTC for rBTC inside Money On Chain's dApp to mint the token of your preference.

What is FastBTC?

According to Sovryn: "FastBTC allows the bi-directional exchange between BTC and RBTC. The FastBTC Relay is not fully decentralized. There is a very brief custodial process where the user entrusts the FastBTC operator to receive the user's BTC and exchange it for RBTC. The exchange is facilitated quickly."

To use FastBTC integration in the Money On Chain app follow these steps:

Go to the web app and connect your wallet. Click on the Bitcoin button on the left sidebar and then you will see this page.
