Max-deviation threshold (bps)

Liquity V1 + V2 (LUSD / BOLD)'s assessment for RD-F-058 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

v1: ~50% deviation between consecutive Chainlink rounds documented in PriceFeed.sol. v2: no bps deviation threshold configured; only staleness-based shutdown. The effective circuit breaker in v2 is the branch-shutdown mechanism (triggered on staleness, not deviation). Exact threshold value confirmed for v1 from source. v2 has no equivalent numeric threshold to report. Yellow: v1 has a configured threshold; v2 does not.
