## Collateral Liquidation Buffer

A collateral liquidation buffer is a risk management mechanism in margin trading and decentralized finance protocols designed to prevent insolvency. It acts as a safety margin, requiring borrowers to maintain collateral value significantly higher than the value of their borrowed assets.

When the value of the collateral drops or the debt rises to a specific threshold, the protocol triggers a liquidation process. This buffer ensures that even if market prices move rapidly, there is enough remaining value to cover the debt and pay for the liquidation costs.

It protects the protocol's liquidity pools from bad debt and systemic failure. By enforcing this cushion, platforms ensure that lenders can always withdraw their funds.

This mechanism is essential for maintaining the stability of under-collateralized or over-collateralized lending markets. It effectively mitigates the risk of rapid price volatility inherent in digital assets.

Without this buffer, the protocol would be vulnerable to sudden market crashes. It is a fundamental component of decentralized margin engines.
