PANews reported on April 23 that, according to Blockworks, researchers Anastasiia et al., in their paper "Vault as a Credit Instrument," proposed that while DeFi lending vaults manage real user deposits, they lack a unified standard for assessing credit risk. The study proposes five core indicators to measure risk under different "mechanical loss channels" and constructs a vault credit scoring system. The paper emphasizes that on-chain execution characteristics (such as oracle bias, liquidation failure, and congestion risk) break the assumptions of traditional financial credit models, necessitating the introduction of new risk quantification methods. This framework combines on-chain data, parameter identification, and stress testing mechanisms, aiming to improve DeFi risk management and transparency standards.
