★ Oracle source = spot DEX pool (no TWAP)

Superstate'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 DEX spot price used anywhere. USTB and USCC pricing is issuer-attested NAV via SuperstateOracle (linear interpolation of checkpoints submitted by NAV Calculation Agent) and Chainlink EACAggregatorProxy (same underlying data routed via Chainlink). No slot0(), no getReserves(), no Uniswap/Curve AMM price read in any oracle path. RWA NAV oracle pattern is immune to flash-loan AMM price manipulation. Green: all oracles use push-oracle with issuer-attestation, no DEX spot price.

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