Getting rBTC and back to BTC with FastBTC

This guide refers to the integration of FastBTC implemented by ROC
RIF 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 RIF On Chain protocol. It lets you exchange your BTC for rBTC inside RIF On Chain's dApp to be able to pay Gas with rBTC.

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 RIF 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.
