Circuit breaker on price deviation

Evidence summary #

Circuit breaker at Scope level: MostRecentOf enforces max_divergence_bps (source divergence triggers error not price acceptance). Price-band protection for stable assets referenced. Specific bps thresholds not confirmed. freeze_price is manual admin tool, not automatic.

Detail #

Scope most_recent_of.rs: if (greater - smaller) / smaller > max_divergence_bps, the composite returns error. This is a divergence circuit breaker at the aggregator level. Exponential.fi references price-band for stable/soft-pegged assets. Individual feed staleness causes freeze (manual via freeze_price, v0.35.0). No automatic protocol-level halt confirmed beyond Scope-level divergence rejection.

Methodology #

Determine whether the protocol halts or reverts if the oracle-reported price deviates by more than X% from a reference within Y blocks.
