Protocol Solvency

Definition ∞ Protocol solvency refers to a decentralized protocol’s ability to meet its financial obligations and maintain the integrity of its asset reserves. This is particularly relevant for lending platforms and stablecoins, ensuring that collateral or backing assets are sufficient to cover liabilities. It signifies the economic health and reliability of a blockchain-based system. Transparent on-chain data often supports the assessment of this metric.
Context ∞ Concerns about protocol solvency frequently surface in DeFi news, especially during periods of market volatility or following significant liquidations. Regular audits and transparent reporting of reserve assets are crucial for building user trust. The robustness of collateralization ratios and risk models is a continuous area of focus for protocol developers and the broader crypto community.
