Liquidation Bonus
A liquidation bonus is a reward provided to a liquidator for successfully closing an under-collateralized position. This bonus is paid out from the liquidated collateral and serves as an incentive to maintain the protocol's health.
By rewarding liquidators, the protocol ensures that there is always a competitive market of actors ready to perform the necessary task of removing bad debt. The size of the bonus is a key parameter that influences how quickly liquidations occur.
If the bonus is too small, liquidators may not be incentivized to act during volatile markets, potentially leading to system failure. If the bonus is too large, it may unnecessarily erode the borrower's remaining collateral.
Balancing this incentive is a central challenge in tokenomics and protocol design. The liquidation bonus effectively crowdsources the risk management function of the lending platform.
It turns the task of monitoring and liquidating positions into a profitable activity for sophisticated market participants.
