Oracle role per asset
Yearn Finance'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 #
Oracle role breakdown: (1) Vault pricePerShare: no oracle — internal accounting only. (2) Strategy-level Chainlink feeds: primary price source for yield-source token accounting per strategy; no documented secondary/fallback per asset at framework level. (3) AprOracle (0x1981AD9F44F2EA9aDd2dC4AD7D075c102C70aF92): APY estimation only, not used in pricePerShare or any settlement path. (4) baseFeeOracle in V2 BaseStrategy: harvest gating (gas cost check), not asset pricing. Yellow: each asset has a primary only, no fallback documented at strategy framework level.
