What Is a ‘Vault’ or ‘CDP’ in a Decentralized Stablecoin System?
A Vault, or Collateralized Debt Position (CDP), is a smart contract that holds a user's locked collateral and allows them to mint a corresponding amount of the stablecoin (debt) against it. It is the core mechanism for over-collateralized stablecoin creation, managing the collateralization ratio and liquidation process.
