Oracle price deviation >X% from secondary
OpenEden's assessment for RD-F-099 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Oracle price deviation signal (T-09 phase 2, tier-B). Partially applicable: TBILL Price Oracle at 0xCe9a6626Eb99eaeA829D7fA613d5D0A2eaE45F40 (Ethereum) is an issuer-push/attested NAV feed — not a DEX spot price. A secondary-source comparison for T-bill NAV is structurally difficult (no DEX liquidity for T-bill NAV; no canonical alternative NAV feed). Chainlink PoR (announced March 2025) covers backing attestation but not real-time price deviation. Signal architecture partially non-applicable for RWA issuer-push NAV. Issuer-push model provides lower oracle-manipulation risk than DEX-spot model. Yellow: signal applicable in principle but secondary-source mapping requires curator work and the architecture reduces risk versus a typical lending oracle.
