Collateralized Debt Position (CDP)

A collateralized debt position is a smart contract mechanism where users lock cryptocurrency assets as collateral to mint or borrow stablecoins and other assets against that collateral. The user maintains ownership of the collateral but cannot withdraw it until the debt is repaid. CDPs employ overcollateralization requirements, meaning users must deposit more collateral value than the debt they generate, protecting the protocol against price volatility and default risk. If collateral value falls below a liquidation threshold, the protocol automatically liquidates the position to maintain system stability. Example: MakerDAO's system allows users to lock Ethereum as collateral into a vault and mint DAI, a USD-pegged stablecoin, as debt against that collateral. Users pay stability fees to maintain their position and must maintain a collateralization ratio above 150% to avoid liquidation. Why it matters for DeFi: CDPs enable users to access liquidity from their crypto assets without selling them, preserving long-term holdings while funding activities. They're critical for stablecoin creation, leverage strategies, and capital efficiency in decentralized finance.
