Liquidation Incentive
The liquidation incentive is a fee or bonus paid to the party who executes a liquidation, encouraging them to monitor and close under-collateralized positions. When a user's position becomes under-collateralized, it is vulnerable to liquidation.
A liquidator steps in to repay the debt and takes a portion of the collateral as a reward for their service. This process ensures that the protocol is cleaned of bad debt and remains solvent.
The size of the incentive must be balanced; it needs to be high enough to attract liquidators even during volatile times, but low enough to minimize the impact on the borrower. This mechanism is a key driver of market efficiency in decentralized lending.
It effectively outsources the monitoring of risk to a decentralized network of participants.
