Circuit breaker on price deviation
USDD (Decentralized USD)'s assessment for RD-F-057 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
No circuit breaker on price deviation documented in available sources. The OSM delay is designed to provide some protection (price changes don't propagate instantly), but: (1) the governance delay is currently disabled per ChainSecurity Jan-2025 audit; (2) no explicit circuit-breaker threshold that halts the protocol on price deviation is documented. Operational monitoring is required per the audit — no automated on-chain protection.
