Liquidator Competition
Liquidator Competition is the rivalry between participants in the market to be the first to identify and execute a liquidation transaction. Because liquidations are profitable, many sophisticated actors use specialized bots to monitor protocols and execute transactions as soon as a position becomes eligible for liquidation.
This competition drives efficiency, ensuring that under-collateralized positions are closed rapidly. However, it also leads to intense battles for transaction inclusion, often resulting in high gas fees and MEV issues.
The competitive nature of liquidations is a double-edged sword: it keeps protocols solvent but can also create congestion and volatility. Protocols must design their liquidation mechanisms to be accessible while still maintaining security.
The evolution of liquidator tools and strategies is a key area of study in market microstructure.
