## Over-Collateralization Mechanisms

Over-collateralization Mechanisms are design features in decentralized finance that require borrowers to provide more value in collateral than the amount of debt they are taking on. This provides a buffer against the volatility of the underlying assets.

By ensuring that the value of the collateral is significantly higher than the debt, the protocol minimizes the risk of default. This is the foundation of many stablecoin and lending protocols in the ecosystem.

It creates a trustless environment where participants do not need to rely on the creditworthiness of others. The specific ratios required are determined by the volatility of the collateral assets.
