Breakage analysis per dependency
Liquity V1 + V2 (LUSD / BOLD)'s assessment for RD-F-052 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Breakage analysis: (1) Chainlink ETH/USD failure v2: WETH branch shuts down permanently; other branches unaffected; (2) Chainlink ETH/USD failure v1: Tellor fallback, then lastGoodPrice if both fail; (3) LST rate provider failure: branch shutdown; (4) Lido/Rocket Pool rate provider failure: branch shutdown. No cross-branch contagion in v2. BOLD stablecoin continues while at least one branch is live. Yellow: analysis covers major dependencies but no formal simulation; curator-derived.
