Circuit breaker on price deviation
Chainlink CCIP'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 fee price deviation. Per-lane token-bucket rate limits act as outflow circuit breakers (capacity exhausted -> transfer reverts until refill). FeeQuoter has no deviation-from-reference check. Rate limits cap per-window outflow (example: 100,000 USD capacity, 167 USD/sec refill).
