Collateral Liquidation Engine

A collateral liquidation engine is the automated system within a lending protocol that monitors the health of user positions and liquidates under-collateralized assets to protect the protocol from insolvency. When a user's collateral value falls below a specific threshold relative to their borrowed amount, the engine triggers a sale of the collateral to repay the debt.

This process must be instantaneous and reliable to ensure the protocol remains solvent during rapid market crashes. The engine relies heavily on accurate, real-time price feeds to determine when a position is eligible for liquidation.

If the price feed is inaccurate or manipulated, the engine may liquidate healthy positions or fail to liquidate underwater ones, leading to bad debt. Efficient liquidation engines are vital for maintaining the economic integrity of decentralized leverage.
