Collateral Valuation

Definition ∞ Collateral valuation is the process of determining the monetary worth of assets pledged to secure a loan or other financial obligation within decentralized finance protocols. This assessment is crucial for calculating loan-to-value ratios and managing liquidation thresholds. Accurate and timely valuation helps protect lenders from market volatility and ensures borrowers maintain sufficient backing. Oracles often provide external price data for these calculations.
Context ∞ The state of collateral valuation involves continuous advancements in oracle network reliability and the use of sophisticated pricing models to handle diverse digital assets. A key discussion addresses the challenges of valuing illiquid or novel tokens accurately and preventing oracle manipulation attacks. Critical future developments include the adoption of more robust decentralized oracle solutions and the integration of real-time market data analytics to enhance valuation precision and security.
