★ Oracle source = spot DEX pool (no TWAP)
Yearn Finance's assessment for RD-F-053 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
CRITICAL CHECK PASSED. V2 Vault.vy: pricePerShare derived from _shareValue(shares) = shares * freeFunds / totalSupply where freeFunds = token.balanceOf(self) + totalDebt - lockedProfit(). No DEX pool read, no slot0(), no getReserves(), no latestAnswer(). V3 VaultV3.vy: pricePerShare() returns _convert_to_assets(10**decimals, ROUND_DOWN) where _total_assets() = self.total_idle + self.total_debt. Confirmed oracle-free by raw source inspection. Strategy-level Chainlink feeds are inputs to strategy profit/loss accounting (not vault pricePerShare). No spot DEX price in vault share-price path.

Methodology #
Determine whether the primary oracle for any asset/market reads spot price from a single DEX pool without a TWAP window or secondary source.
