crvUSD

crvUSD is a collateralised stablecoin whose distinguishing feature is what happens when your collateral falls in value. Instead of a liquidation that closes the position at once, it converts collateral gradually through an automated market maker — and can convert back if the price recovers.

Conventional liquidation is all or nothing

On most lending protocols, crossing a threshold triggers a liquidation that sells collateral and charges a penalty. A brief wick can destroy a position that would have been fine minutes later, and cascading liquidations amplify moves precisely when markets are thinnest.

Soft liquidation converts continuously

crvUSD's LLAMMA mechanism places collateral into an AMM across a price range. As the price falls the collateral is progressively sold into the stablecoin; as it rises the process reverses. There is no single liquidation event, and a recovery genuinely undoes part of the conversion rather than leaving you closed out at the bottom.

The cost is continuous, not sudden

Passing back and forth through the range means repeatedly buying high and selling low relative to the eventual outcome — the same divergence loss that liquidity providers experience. A borrower in a choppy market pays a steady toll instead of a one-off penalty. It is a smoother cost, not an absent one.

Why this matters beyond one stablecoin

Liquidation design is where most DeFi lending losses originate, and cascades during volatility have caused far more damage than contract bugs. A mechanism that degrades gradually rather than discontinuously is a genuine contribution to that problem, whatever one thinks of the stablecoin itself.

What secures it

crvUSD is overcollateralised, with parameters and accepted collateral set by governance of the protocol that issues it. Its backing is on-chain and verifiable, and its risks are the risks of its collateral set and its novel liquidation mathematics.
