Circuit breaker on price deviation
Axelar Network'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 price-deviation circuit breaker (no price oracle). However, the mintLimiter (per-symbol, per-6-hour-epoch cap) functions as a volume-based rate-limit circuit breaker on token minting. Yellow because while no price circuit breaker exists, the volume cap provides meaningful damage limitation for a bridge exploit scenario, but it is a volume cap not a price-anomaly detector.

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