Circuit breaker on price deviation
Lombard Finance'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 general-purpose price-deviation circuit breaker found in Lombard's own oracle contracts for BTC/USD. StakedLBTCOracle has an implicit ratio-change threshold (0.1% per interval) that limits the magnitude of ratio updates — acting as a mild circuit breaker for the LBTC/BTC rate oracle. Consumer-side circuit breakers (e.g. Aave's maxRatio deviation) are downstream protocol responsibility. Yellow: partial protection via StakedLBTCOracle ratio-change threshold; no protocol-level circuit breaker for BTC/USD price deviation.

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