Collateral Liquidation

Definition

Collateral liquidation occurs in decentralized finance lending protocols when the value of a borrower’s collateral falls below a predetermined threshold, often due to market price fluctuations. To protect the lender, the protocol automatically sells a portion of the collateral to repay the loan and maintain solvency. This automated process is a core risk management mechanism in many DeFi applications. It ensures the stability of lending platforms by managing loan-to-value ratios.
