Oracle role per asset

Lombard Finance's assessment for RD-F-049 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

BTC/USD: Chainlink is primary on Ethereum; RedStone is primary on BNB/Base/Solana. No on-chain fallback declared within Lombard's own source — downstream consumer protocols are responsible for their own fallbacks. StakedLBTCOracle: primary only for LBTC/BTC rate with no fallback; reverts on proof failure. PoR: multi-provider (Lombard + RedStone) provides cross-check redundancy. Yellow because Ethereum BTC/USD has Chainlink with no on-chain fallback in Lombard source; StakedLBTCOracle has no fallback oracle.
