A collateralized debt position (CDP) is a crypto borrowing position backed by assets locked as collateral. A protocol records the collateral and associated debt under its own rules; if the position no longer meets those rules, some or all of the collateral may be liquidated.
What the term means
CDP describes a collateral-backed debt position, but it does not name one universal implementation. Sky Protocol documents its comparable user positions as Vaults, while Liquity calls its borrower position a Trove. Each protocol sets its own accepted collateral, debt asset, fees, risk parameters, and liquidation process.
Some systems create a stablecoin when a user draws debt against collateral. Pool-based lending works differently: borrowers access assets supplied to a liquidity pool. Both designs may require collateral and permit liquidation, but the borrowed asset comes from a different part of the system.
How a CDP-style position works
- Choose an implementation: the protocol specifies which assets can be collateral, how prices are measured, and which debt assets are available.
- Lock collateral: the user deposits an accepted asset into the protocol’s smart contracts.
- Draw debt: the user borrows or generates an asset within the protocol’s limits. Fees or debt adjustments depend on the implementation.
- Manage the position: changes in collateral prices, debt, or protocol parameters can change the position’s risk.
- Repay or face liquidation: repaying the required debt and fees may allow the user to withdraw remaining collateral. If a risk threshold is crossed, liquidation rules may sell or transfer collateral to cover debt.
Risks and tradeoffs
- Market risk: a fall in collateral value can bring a position closer to its liquidation threshold.
- Oracle and liquidity risk: price feeds, market gaps, and limited liquidity can affect whether liquidation operates as intended.
- Contract and governance risk: code, authorized modules, collateral adapters, and changeable parameters can affect user funds.
- Capital efficiency: requiring collateral worth more than the debt can reduce the amount of capital available for other uses.
Social Media Sentiment
In a July 2026 r/defi discussion about overcollateralization, commenters debated the capital tied up in collateral against the buffer it can provide. A separate November 2025 discussion about borrowing risk focused on collateral quality, liquidation buffers, and monitoring. These are small, self-selected threads; they show concerns voiced by participants, not a reliable measure of DeFi users overall.
