Oracle role per asset
crvUSD (Curve Stablecoin)'s assessment for RD-F-049 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
crvUSD/USD: AggregatorStablePrice (Primary, for rate-setting only). All collateral markets: CryptoWithStablePriceAndChainlink class (Primary, for LLAMMA price bands). Chainlink is a ±1.5% safety limit within the primary oracle contract, not an independent fallback oracle — simultaneous EMA+Chainlink failure leaves no further recourse.
