Risk Oracle
B. Protocol’s risk oracle is an on-chain decentralized system that provides objective risk-related information about different assets, protocols, or platforms within the DeFi ecosystem. The oracle assesses objective risk-related parameters, such as liquidity and volatility of assets, borrowing and lending caps, liquidations at risk, existing bad debt, smart contract audits, and updates, etc.
Platforms and users can utilize the data provided to make informed decisions regarding listing and managing their lending markets, setting risk parameters that are aligned with the platform’s subjective risk appetite. More information about the risk oracle can be found in B. Protocol’s
LTV Ratio
LTV is an acronym for Loan-To-Value ratio. It is a measure of the ratio of a user’s loan to the value of their collateral, and it is the DeFi equivalent of a credit score in traditional finance. LTV is a vital metric for gauging the risk and security of loans in the DeFi ecosystem, and loans are often overcollateralized to reduce the likelihood of losses due to defaults, market volatility, or sudden declines in collateral value.
LTV ratio is typically expressed as a percentage and calculated using:
When a user’s LTV rises above a predefined threshold,
Risk Appetite
Risk Appetite is commonly defined as the amount and type of risk that an organization is willing to accept or assume. This appetite can vary from platform to platform and from DAO to DAO as they each have their perspective on what is to be considered as risky. Currently, most risk assessment frameworks in DeFi combine and mash this subjective, qualitative risk appetite with objective and measurable risk-related data feeds.
B.Protocol separates the two through its SmartLTV formula that calculates the LTV based on objective data together with a risk level factor that represents the subjective risk appetite. The risk level factor is a single numerical value that aims to represent a desirable safety margin by accounting for potential deviations from previously observed stats to anticipated values in black swan events. For instance, it considers scenarios where volatility could be three times higher than what was previously recorded.
Ultimately, this factor enables lending protocols to tailor their risk management strategies to their specific goals and tolerances while empowering users with the transparency necessary to make informed decisions.
Circuit Breakers
Circuit breakers are mechanisms that temporarily halt or limit specific activities or trading within a protocol or platform to manage extreme market volatility or prevent sudden crashes. The mechanism is triggered by predefined conditions, such as rapid price declines, high volatility, or abnormal trading volumes. Once activated, circuit breakers halt activities like trading, lending, borrowing, or other relevant operations to prevent insolvency, protect users from losses, and offer time for the market to stabilize.
