Oracle providers used
OpenEden's assessment for RD-F-048 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
TBILL uses a single issuer-push/attested oracle (TBillPriceOracle, OpenEden-operated) on Ethereum (0xCe9a6626Eb99eaeA829D7fA613d5D0A2eaE45F40) and Arbitrum (0xc0952c8ba068c887B675B4182F3A65420D045F46). The oracle exposes a Chainlink-compatible interface (latestRoundData()) but data is operator-attested NAV, not a DEX pool. No TWAP or spot DEX oracle used. Chainlink Proof of Reserve announced March 2025 for USDO backing verification; on-chain feed address not confirmed in public docs as of 2026-05-16. Multiple Chainlink feed addresses in the data-cache oracle_feeds block appear to be pipeline noise — none confirmed as consumed by TBILL vault logic.
