How Liquidation Works
Liquidation is a key safety feature in LNDfi, triggered when a user's collateral value falls below a certain threshold. This ensures loans are repaid and keeps the liquidity pool stable, even in volatile market conditions.
Liquidation Threshold
The liquidation threshold defines when a loan becomes undercollateralized. For example, if the threshold is 90%, any position where borrowed value exceeds 90% of collateral value is at risk of liquidation.
Understanding the Health Factor (HF)
The Health Factor (HF) measures the risk of liquidation:
HF > 1 → Safe position
HF < 1 → High risk of liquidation
If the Health Factor drops below 1, the protocol may liquidate collateral to cover outstanding debt.
Liquidation Examples
Scenario 1:
Alice deposits 800 S as collateral and borrows 500 S worth of USDC.
If her Health Factor drops below 1, liquidation can occur.
A liquidator repays 250 S worth of USDC (50% of the debt) and receives 262.5 S as a reward (including a 5% liquidation bonus).
Scenario 2:
Alice deposits 400 S + an equivalent amount of stS, then borrows 400 S worth of USDC.
If liquidation is triggered, a liquidator repays 200 S worth of USDC and claims stS due to its higher 12% liquidation bonus, receiving 224 S worth of stS.
Liquidation Bots & Permissionless Liquidation
Anyone can act as a liquidator if the process is profitable. To ensure smooth operations, LNDfi will initially deploy automated liquidation bots to manage liquidations efficiently.
Liquidation Penalty
Each collateral type has a liquidation penalty, which incentivizes liquidators to participate while maintaining protocol stability. The penalty varies based on asset risk.
