Liquidator Profitability Modeling
Liquidator profitability modeling is the quantitative analysis used to determine if the financial gain from executing a liquidation exceeds the associated costs. Costs include transaction fees, gas prices, and the potential market impact of selling the liquidated collateral.
Liquidators must calculate the expected bonus against the risk of the asset price moving against them during the liquidation process. This model often incorporates volatility metrics, expected slippage, and the latency of the blockchain network.
If the model shows negative expected value, liquidators will abstain from acting, potentially leaving the protocol vulnerable. Advanced liquidators use automated bots to execute these calculations in milliseconds to capture arbitrage opportunities.
It is a fundamental component of maintaining healthy market microstructure in decentralized lending.
