★ Oracle source = spot DEX pool (no TWAP)
Ondo 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 #
**Neither custom oracle uses a spot DEX pool.** Pricer.sol is an off-chain-calculated NAV posted daily. RWADynamicOracle.sol is a time-range interpolation formula with admin-set interest rates. Chainlink feeds (Flux) are not DEX pools. The custom oracle design is a *different* risk class (centralized trust, not DEX manipulation), addressed primarily in F051 and F059. Literal ★ RD-F-053 criterion (spot DEX source) not met.
