Collateralized Debt Positions (CDPs) are a fundamental mechanism in decentralized finance (DeFi) where users lock digital assets as collateral to generate or borrow another asset, typically a stablecoin. The collateral serves as security for the debt, ensuring that the borrowed amount is backed by sufficient value. The overcollateralization ratio is a critical parameter that determines the safety margin against price fluctuations of the underlying asset.
Debt
The debt component represents the amount borrowed against the collateral, often denominated in a stablecoin to maintain purchasing power. Users retain ownership of the collateral while accessing liquidity, creating a leveraged position. The debt accrues interest, which must be repaid along with the principal to retrieve the collateral.
Mechanism
The core risk management mechanism of a CDP is liquidation. If the value of the collateral falls below a predetermined threshold relative to the debt, the protocol automatically liquidates the collateral to repay the outstanding loan. This automated process protects the system’s solvency and ensures the stability of the stablecoin peg.
