RIF On Chain is evolving, introducing multi-collateral support for USDRIF on Rootstock.
With V3, USDRIF can be issued using both RIF and DOC as collateral. RIF remains the protocol’s primary growth asset. DOC, a Bitcoin-backed stablecoin on Rootstock, adds a stable collateral layer that gives USDRIF more room to scale.
Why this upgrade
As USDRIF adoption grows, relying on a single collateral asset can limit how efficiently supply scales and adapts to market conditions.
V3 addresses this by combining two complementary assets:
- RIF → drives growth and absorbs volatility
- DOC → adds stability and capital efficiency
Together, they support a single USDRIF supply while enabling more consistent expansion and improved market responsiveness.
Two collateral sources, one USDRIF
V3 introduces a dual-collateral architecture built around two coordinated buckets:
RIF bucket
- Uses RIF as collateral
- Supports USDRIF issuance
- Issues RIFPRO, the residual token that absorbs volatility and captures upside from RIF
DOC bucket
- Uses DOC as collateral
- Supports capital-efficient USDRIF issuance
- Issues ROCR, the residual token of the DOC bucket
Both buckets contribute to a single, fungible USDRIF supply.
Users can deposit RIF or DOC into their respective buckets and choose to mint:
- USDRIF (stablecoin)
- The bucket’s residual token (RIFPRO or ROCR)
- Or both, depending on their preferred exposure
This allows the system to dynamically balance stability and growth without changing its core mechanics.
Stronger stability by design
Adding DOC introduces a stable collateral layer that reduces reliance on RIF price movements and improves overall system resilience. To coordinate this dual-collateral model, V3 introduces a Multi-Collateral Guard, a core component that manages collateral across buckets, redistributes risk when needed, and helps maintain system-wide balance. The result is a protocol better equipped to handle volatility and perform under market stress.
Seamless upgrade for users
This upgrade is fully non-disruptive. Users are not required to migrate funds, adjust positions, or take any manual action. All changes are implemented through proxy contract upgrades, ensuring a smooth transition while preserving full access to funds and protocol functionality.
No changes to core protocol rules
V3 does not alter the fundamental mechanics of RIF On Chain. Minting and redemption logic remain the same, collateralization rules are unchanged, and the fee structure continues as before. Rather than modifying existing behavior, this upgrade extends the protocol by introducing new capabilities on top of a proven foundation.
Improved user experience
A redesigned RIF On Chain dApp will launch alongside V3.
It brings a cleaner interface, improved navigation, and better visibility into collateral and positions. Multi-collateral interactions will be easier to understand, with clearer data and more responsive performance.
Users will also benefit from greater flexibility:
- Ability to choose between RIF and DOC
- Better risk management depending on market conditions
- More efficient capital allocation
Joint operations are also enhanced, allowing users to combine actions like minting, redeeming, and adjusting positions in a single transaction.
Governance and rollout
As with all upgrades, V3 went through governance. The process included proposal submission, community vote, and execution via a changer contract. A coordinated dApp update followed the approval.
The bigger picture
RIF On Chain V3 makes USDRIF a multi-collateral stablecoin built natively on Rootstock, combining:
- RIF-backed growth
- Bitcoin-backed stable liquidity through DOC
- On-chain transparency
- Automated stabilization mechanisms
- A single fungible USDRIF supply
This upgrade also arrives at a moment when stablecoin activity on Rootstock is accelerating.
Over the last year, the ecosystem has expanded with the arrival of assets such as USDT0, bringing omnichain Tether liquidity into Bitcoin DeFi on Rootstock, and more recently USDb, a Bitcoin-aligned stablecoin built for enterprise payments and treasury operations.
Together, these developments point in the same direction: Bitcoin is no longer just a passive reserve asset. Stablecoins, lending markets, payments, and on-chain financial infrastructure are increasingly being built directly around Bitcoin and secured by Bitcoin-linked systems.
Rootstock is uniquely positioned for this shift.
Unlike standalone L1s that bootstrap their own security, Rootstock is merge-mined with Bitcoin, inheriting security from Bitcoin’s proof-of-work network while supporting EVM-compatible smart contracts. That combination allows protocols like RIF On Chain to build decentralized financial infrastructure with Bitcoin-aligned security guarantees and fully programmable on-chain execution.
V3 strengthens USDRIF’s role inside that ecosystem.
By combining RIF and DOC in a coordinated multi-collateral architecture, RIF On Chain expands the capacity, resilience, and utility of a decentralized stablecoin designed specifically for the Bitcoin economy.
