★ Oracle source = spot DEX pool (no TWAP)
BlackRock USD Institutional Digital Liquidity Fund (BUIDL)'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 #
BUIDL does not use a spot DEX pool oracle. RedStone TSSO is a push-oracle with authorized publisher (Securitize Fund Services), not a DEX pool spot price read. The $1.00 NAV is maintained off-chain by regulated fund accounting. F053 trigger condition does not apply.
