The decentralized finance (DeFi) landscape is continually evolving, with new methodologies for assessing and mitigating risks. Traditional financial models often fall short in addressing the unique challenges posed by the volatile and permissionless nature of blockchain-based assets. In response, several DeFi protocols have developed smart risk assessment techniques that leverage on-chain data and advanced mathematical models. Among these, B Protocol's smart Loan-to-Value (LTV) ratio, Gauntlet's Value at Risk (VaR), and Morpho's risk layer stand out for their novel approaches to managing risk. This blog post delves into these methodologies, assessing their strengths, applications, and determining which metric might be best suited for different types of users or platforms.
