Soft liquidation is a broad label for liquidation designs that reduce a borrower’s collateral exposure gradually or in stages instead of closing the entire position at one threshold. There is no single rulebook behind the term: protocols can implement different mechanisms, and the label does not mean liquidation is harmless or loss-free.
Curve LLAMMA as One Specific Example
Curve’s LLAMMA is a protocol-specific example used with certain crvUSD lending markets. It places collateral across price bands. As the relevant market price moves through a position’s liquidation range, arbitrage activity can exchange some collateral for the borrowed asset; if the price moves back, the mechanism can exchange some of that asset back into collateral.
This is a gradual change in the position’s asset mix, not a promise that the borrower can always avoid a loss. Curve’s documentation says soft-liquidation and de-liquidation can incur losses. Interest and other position costs can also affect health. The details depend on the market, collateral, price path, fees, liquidity, and the number and placement of bands.
Soft and Hard Liquidation
A soft-liquidation phase may change what backs a loan without immediately closing it. A hard liquidation is a separate process in which the position becomes eligible for a more direct debt repayment and collateral transfer under that protocol’s rules. In Curve’s documented design, the liquidation range and the health condition for hard liquidation are distinct concepts.
Other protocols may use “soft liquidation” for a different staged or partial mechanism. Compare the protocol’s own rules for trigger conditions, how collateral is sold, fees, and whether a later price recovery can restore collateral.
What Borrowers Should Check
Review the liquidation threshold or range, how the protocol determines prices, the current debt and interest, and the effects of market depth and trading costs. A move back into a safer price range may not reverse every cost already incurred. A position can still deteriorate enough to face hard liquidation.
Treat “soft” as a description of the liquidation path, not as a safety rating. Smart-contract risk, oracle design, collateral volatility, liquidity, and protocol-specific parameters remain relevant.
