Chainlink aggregator min/max bound misconfig
Liquity V1 + V2 (LUSD / BOLD)'s assessment for RD-F-060 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Chainlink ETH/USD feed (0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419) is one of Chainlink's highest-quality, most mature feeds (live since 2019, 0.5% deviation threshold, 3600s heartbeat per cache). minAnswer and maxAnswer bounds require on-chain RPC call to verify exact values -- not directly obtainable via WebFetch. Yellow pending curator on-chain verification. High-quality feed lowers probability of misconfig but does not substitute for verification.

Methodology #
Determine whether the Chainlink aggregator's `minAnswer` and `maxAnswer` circuit-breaker bounds are misconfigured (too wide or too narrow) for the asset class.
