Circuit breaker on price deviation
mETH Protocol's assessment for RD-F-057 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Oracle.sol _sanityCheckUpdate() acts as circuit breaker: protocol auto-pauses if Beacon Chain balance loss exceeds maxConsensusLayerLossPPM=1000 (0.1% per report), or gain is outside [minConsensusLayerGainPerBlockPPT, maxConsensusLayerGainPerBlockPPT], or validator count decreases abnormally. Failed sanity checks pause the protocol and mark the update as pending for resolver review.
