Oracle price deviation >X% from secondary
Usual (USD0 / bUSD0 / USUAL)'s assessment for RD-F-099 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
USD0 trades at $0.9981 (CoinGecko 2026-05-17), confirming oracle reads are functioning normally for the primary stablecoin. Chainlink USDC/USD heartbeat is 82800s and USDT/USD is 86400s — the longest-heartbeat feeds in the stack, creating staleness windows relevant to a stablecoin collateral protocol. No oracle deviation events reported in public sources. This is a T-09 phase-2 signal not yet instrumented; green reflects current peg status, not live oracle monitoring.
