A collateralized debt position is an on-chain borrowing position that locks cryptoassets against stablecoin or other protocol debt.
A collateralized debt position (CDP) is an on-chain borrowing position in which a user locks approved cryptoassets in a smart-contract system and incurs stablecoin or other protocol-denominated debt against them. The position must remain above the protocol’s required collateral ratio or health threshold; otherwise, some or all collateral can be liquidated under the protocol rules.
CDP is a DeFi term and is unrelated to a collateralized debt obligation (CDO), despite the similar initials.
Exact mechanics differ across protocols and can change through governance or software upgrades.
A 200% ratio means the oracle value of collateral is twice the debt. It does not mean the user has a 100% safety margin after liquidation penalties, price gaps, fees, and transaction costs.
A user locks 10 tokens valued at $3,000 each and borrows $15,000 of stablecoin debt.
| Measure | Calculation | Result |
|---|---|---|
| Initial collateral value | 10 x $3,000 | $30,000 |
| Debt | $15,000 | |
| Initial collateralization ratio | $30,000 / $15,000 | 200% |
| Assumed liquidation ratio | 150% | |
| Collateral value at threshold | $15,000 x 150% | $22,500 |
| Token price at threshold | $22,500 / 10 | $2,250 |
Under these simplified assumptions, a decline from $3,000 to $2,250 per token reaches the 150% threshold. Accrued debt fees would raise the debt and move the threshold price higher. Oracle methodology, liquidation incentives, and price gaps can cause realized outcomes to differ from the simple calculation.
Users may borrow stablecoins without selling collateral, obtain liquidity for trading or payments, refinance another on-chain position, or build leveraged exposure. These uses can create taxable, legal, and financial consequences that vary by jurisdiction.
Retaining collateral exposure cuts both ways. If collateral rises, the user still benefits after debt and fees. If it falls, leverage accelerates equity loss and can trigger forced liquidation.
| Feature | CDP | Traditional secured loan |
|---|---|---|
| Underwriting | Primarily collateral and protocol rules | Borrower cash flow, credit, collateral, and legal documentation |
| Collateral custody | Smart contract or protocol-controlled address | Borrower, custodian, lender, or control arrangement |
| Valuation | On-chain oracle inputs | Appraisal, market price, borrowing base, or lender valuation |
| Margin enforcement | Automated or protocol-triggered | Contractual and legal process, sometimes discretionary |
| Borrower identity | Can be pseudonymous | Usually identified through legal and compliance processes |
| Legal recourse | Often limited or uncertain beyond on-chain collateral | Defined by contract, security law, and jurisdiction |
The economic similarity is collateralized borrowing; the enforcement, identity, governance, and legal frameworks are materially different.
Protocols can use auctions, automated market makers, direct transfers, keeper networks, or other mechanisms. A liquidator may receive a discount or penalty-funded incentive. The borrower can lose more collateral than the amount needed to repay principal because fees, penalties, slippage, and gas costs also matter.
During sharp market moves, many positions can liquidate together. Forced sales may push collateral prices lower, triggering additional liquidations and creating procyclical leverage.
Crypto collateral can gap lower before a user can act. Oracles can lag, fail, or be manipulated. Smart contracts can contain defects, governance can change risk parameters, and blockchains can become congested. Stablecoin depegging can make repayment or collateral accounting more expensive than expected.
