★ Oracle source = spot DEX pool (no TWAP)

Circle USYC'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] No spot DEX pool oracle. USYC NAV oracle (GenericNextPriceAggregator) is an issuer-controlled push oracle where a designated reporter pushes values via transmit(uint256 _answer, uint256 _updatedAt). No slot0(), no getReserves(), no DEX pool dependency. Not manipulable via flash loan. Confirmed via Etherscan source of oracle implementation contract.
