Lombard Finance'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 BTC/USD (0xF4030086522a5bEEa4988F8cA5B36dbC97BeE88c) is a mature Tier-1 Chainlink feed unlikely to have default type(int192).max bounds given its market maturity and Chainlink's established deployment practices. However, no direct on-chain RPC call to read minAnswer/maxAnswer was performed in this assessment. Yellow: established Tier-1 feed (low effective risk); min/maxAnswer values not directly verified via on-chain read in this assessment pass.
