RIF (Rootstock Infrastructure Framework) is designed to accelerate adoption of Bitcoin DeFi on Rootstock, the longest running and largest Bitcoin sidechain. RIF powers incentives, interoperability and infrastructure for building BTCFi applicatios on Rootstock. This include powering the RootstockCollective DAO which supports new builders and pays members rewards in RIF and BTC. RIF also powers a range of protocols for payments, stablecoins (USDRIF) and domaining (RNS). The Rootstock Infrastructure Framework is a full tech-stack for building on Bitcoin where the $RIF token is required to interact with these services.
