Single-pool oracle (no medianization)

Compound V3 (Comet)'s assessment for RD-F-056 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Chainlink feeds aggregate 16-31 operators internally. However, no cross-provider medianization at protocol level — single Chainlink feed per asset with no secondary source cross-validation.

Detail #

Chainlink itself is internally medianized (not a single-pool oracle). But Comet uses exactly one oracle feed per asset with no fallback or secondary source comparison. If Chainlink reports a wrong price for any asset, no protocol mechanism detects or corrects it.
