Generate Yield
BTCFi on Rootstock means lending, borrowing, yield, and liquidity apps that use rBTC and other assets on an EVM-compatible chain anchored to Bitcoin.
This section is for builders who implement strategies and vault integrations. Who may use a live vault product depends on the program, jurisdiction, and whether access is institutional, retail, or partner-only.
Core pillars
| Pillar | Description | Where to go |
|---|---|---|
| Vaults SDK | ERC-4626 style flows for the USDRIF vault on Rootstock. | Integrate USDRIF Vault. Install and API details stay in the Vaults SDK README. |
| Stable units of account | USD-pegged assets such as USDRIF for pricing and debt. | RIF On Chain |
| Liquidity and credit | Lending and borrowing markets on top of rBTC and stable assets. | Protocol documentation for the venues you integrate (for example Tropykus, Money on Chain) |
Key Concepts
1. rBTC (Bitcoin-pegged gas and collateral)
rBTC is the native asset on Rootstock. It is pegged 1:1 with BTC through the PowPeg. When you peg in, BTC is locked on Bitcoin and rBTC is available on Rootstock. You pay gas in rBTC and use it as collateral in DeFi protocols.
2. USDRIF and stablecoins
Bitcoin is volatile, so many apps need a stable unit of account. USDRIF is a decentralized, USD-pegged asset with Bitcoin-backed collateral. Read the issuer and pool documentation before you integrate it in production.
3. Liquid staking (LSTs)
Some protocols issue receipt tokens when you stake rBTC (for example st-rBTC). Behavior, rewards, and risk depend on each protocol. Read the contract and liquidation rules before you treat an LST as collateral elsewhere.
