The decentralized stablecoin market is vast, yet many projects fail prematurely. Even Terra's LUNA and UST, once valued at tens of billions, collapsed rapidly. Now, Curve—with $3.7 billion in TVL—joins the competition with its innovative stablecoin, crvUSD (Curve.Fi USD Stablecoin).
Recent GitHub updates reveal Curve's stablecoin whitepaper (finalized in October) and code. While naming isn't explicit in the document, the code confirms "crvUSD" as the official abbreviation. This move aims to address Curve's revenue challenges through stability fees and PegKeeper mechanisms, countering critiques of CRV's inflationary model.
Key innovations in crvUSD's design include:
- LLAMMA (Lending-Liquidation AMM Algorithm)
- PegKeeper stability mechanism
- Monetary policy adjustments
Smoother Liquidations with LLAMMA
Traditional protocols like Aave and MakerDAO face issues during mass liquidations—sharp price drops and bad debt. For instance, a June 2022 MakerDAO liquidation crashed ETH prices from $1,300 to under $1,000 on Uniswap due to low liquidity.
How LLAMMA Works:
- Overcollateralized Minting: Users deposit assets (e.g., ETH) to borrow crvUSD.
Continuous Liquidation Range: Instead of one-time liquidation, crvUSD uses an AMM to gradually sell collateral if prices fall into a "liquidation band."
- If ETH rebounds within this band, crvUSD buys back ETH automatically.
- If ETH drops below the band, liquidation completes fully (like traditional systems).
- Test Results: Curve's simulations show just 1% collateral loss after a 10% price dip and recovery over 72 hours.
Pros:
- Reduces abrupt market impacts.
- Recovers collateral during price rebounds.
Cons:
- Higher likelihood of partial liquidations during minor volatility.
PegKeeper: The Automatic Stabilizer
crvUSD maintains its $1 peg through PegKeeper's algorithmic adjustments:
| Scenario | PegKeeper Action | Effect |
|---|---|---|
| crvUSD > $1 | Mints crvUSD without collateral and adds liquidity to pools | Increases supply, pushing price down |
| crvUSD < $1 | Withdraws crvUSD liquidity | Reduces supply, restoring peg |
Similar to Frax's AMO, this avoids reliance on centralized stablecoins (e.g., MakerDAO’s PSM).
Monetary Policy & Debt Management
Curve’s monetary policies adjust based on:
Debt/Supply Ratio:
- If >5%, parameters incentivize borrowing (increasing dst burn).
- If low, encourages loan repayments (growing system debt).
Key Advantages for Curve
- LP Token Collateralization: Future integration with 3pool LP tokens could boost capital efficiency.
- veCRV Governance: Curve’s existing veCRV holders can direct crvUSD liquidity, easing adoption.
- Revenue Streams: Stability fees and PegKeeper profits may offset Curve’s low trading fees (0.01–0.05%).
- Native Oracle: Uses Curve’s DEX prices (e.g., tricrypto pool for ETH), reducing oracle costs.

FAQs
Q: How does LLAMMA prevent bad debt?
A: By dynamically adjusting liquidations, it minimizes scenarios where collateral can’t cover loans.
Q: Is crvUSD pegged solely algorithmically?
A: Yes, via PegKeeper’s mint/burn actions, backed by implicit liquidity pool support.
Q: Can non-Curve assets be collateral?
A: Likely no—Curve relies on its existing pools (e.g., ETH via tricrypto) for price feeds.
