About Resupply Fi
Resupply Fi is a decentralized lending protocol built on Ethereum, enabling users to supply crvUSD and frxUSD across Curve Lend and Fraxlend markets and borrow reUSD — a stable, yield-bearing stablecoin designed for the DeFi ecosystem.
Our Mission
Resupply Fi was founded with a clear mission: to make decentralized lending more efficient, transparent, and rewarding for participants across the DeFi ecosystem. By bridging Curve Lend and Fraxlend markets under a unified protocol, Resupply Fi eliminates the fragmentation that has historically made yield optimization complex and inaccessible.
We believe in a future where stable assets can be put to work seamlessly — where supplying collateral earns meaningful yields, where borrowing costs are competitive and transparent, and where governance is fully on-chain and community-driven. Resupply Fi is built to realize that future, one block at a time.
The protocol is entirely non-custodial. Users retain full control of their assets at all times, and all protocol parameters are governed by RSUP token holders through on-chain proposals.
Protocol Overview
Resupply Fi operates as a meta-lending layer built on top of the most trusted stablecoin infrastructure in DeFi. Users deposit crvUSD or frxUSD into one of the supported lending markets and receive the ability to borrow reUSD — a native stablecoin minted by the Resupply Fi protocol.
The borrowed reUSD can be deployed across a growing set of yield-bearing opportunities including the reUSD Insurance Pool, Savings reUSD (sreUSD), and various RSUP/reUSD liquidity pools. This composable architecture allows users to stack yields and optimize capital efficiency.
Revenue generated by the protocol is distributed to RSUP stakers, insurance pool providers, and sreUSD holders, aligning incentives across all participant classes and ensuring sustainable growth.
Core Features
Lending Markets
Supply crvUSD or frxUSD to Curve Lend and Fraxlend markets as collateral and borrow reUSD at competitive rates. Choose from markets backed by WBTC, WETH, wstETH, sfrxETH, sUSDe, scrvUSD, sfrxUSD, and sreUSD.
reUSD Stablecoin
reUSD is Resupply Fi's native stablecoin. It is minted when users borrow against their collateral and can be deployed into yield-bearing positions throughout the ecosystem for additional returns.
Insurance Pool
Deposit reUSD into the Insurance Pool to earn protocol revenue and serve as a backstop for the system. Insurance pool providers receive a share of borrowing fees distributed by the protocol.
Savings reUSD (sreUSD)
sreUSD is a yield-bearing wrapped version of reUSD. Holding sreUSD means your balance compounds over time as protocol revenue accrues automatically to sreUSD holders.
Liquidity Pools
Provide liquidity to RSUP/reUSD pools to earn trading fees and liquidity mining rewards. Deep liquidity pools ensure efficient price discovery and low-slippage trades for reUSD and RSUP.
RSUP Governance
RSUP is the governance token of Resupply Fi. Holders can submit and vote on proposals to adjust protocol parameters, add new markets, allocate revenue, and shape the future development of the protocol.
Supported Tokens
| Token | Role | Description |
|---|---|---|
| reUSD | Protocol Stablecoin | Native stablecoin minted by Resupply Fi against supplied collateral. Used across insurance pools, savings products, and liquidity pairs. |
| RSUP | Governance Token | Controls protocol parameters through on-chain governance. Stakers receive a share of protocol revenue. |
| crvUSD | Collateral | Curve Finance's native stablecoin. Accepted as collateral across multiple Curve Lend markets on Resupply Fi. |
| frxUSD | Collateral | Frax Finance's USD stablecoin. Accepted as collateral across Fraxlend markets integrated with Resupply Fi. |
| sreUSD | Yield Wrapper | Interest-bearing wrapper for reUSD. Balance compounds automatically as the protocol generates revenue. |
| WBTC / WETH | Collateral Asset | Blue-chip crypto assets that can be used as underlying collateral within Curve Lend and Fraxlend markets supported by Resupply Fi. |
| wstETH / sfrxETH | Yield-Bearing Collateral | Liquid staking tokens that earn staking rewards while also serving as collateral in Resupply Fi lending markets. |
| sUSDe / scrvUSD / sfrxUSD | Yield-Bearing Collateral | Savings-wrapped stablecoins that accrue yields from their respective protocols while being deployed as collateral in Resupply Fi. |
How It Works
Step 1 — Choose a Market. Browse the Resupply Fi Lending Markets and select the collateral type and protocol (Curve Lend or Fraxlend) that best matches your strategy and risk profile.
Step 2 — Supply Collateral. Deposit crvUSD, frxUSD, or another supported collateral asset into your chosen lending vault. Your collateral begins earning the base lending vAPR immediately.
Step 3 — Borrow reUSD. Against your deposited collateral, borrow reUSD. The borrowing cost is partially or fully offset by borrow rewards paid in RSUP and other incentive tokens, making your effective borrowing rate very competitive.
Step 4 — Deploy reUSD. Put your borrowed reUSD to work. Deposit into the Insurance Pool, wrap into sreUSD for passive compounding, or provide liquidity in RSUP/reUSD pools to earn additional yields on top of your collateral returns.
Step 5 — Participate in Governance. Acquire RSUP tokens to participate in protocol governance. Vote on proposals, suggest new markets, and help shape the future of Resupply Fi.
Security & Audits
Resupply Fi is built with security as a first principle. The protocol's smart contracts have been developed by experienced DeFi engineers with deep roots in the Curve and Frax ecosystems, drawing on battle-tested contract patterns and rigorous internal review processes.
The protocol is non-custodial by design — users hold their own assets and no single entity can access user funds. All protocol logic is executed deterministically on-chain, and contract upgrades are subject to governance approval with appropriate time-locks.
Full source code is available on GitHub for community review. We encourage developers, auditors, and security researchers to examine the codebase and report any findings through our official channels.
Team & Community
Resupply Fi is built by a team of DeFi-native developers and researchers with deep experience across the Curve, Convex, and Frax ecosystems. The team is pseudonymous, in line with the ethos of decentralized finance, and fully committed to long-term protocol development.
