Single-pool oracle (no medianization)
dYdX v4 (dYdX Chain)'s assessment for RD-F-056 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Slinky performs medianization across multiple CEX price feeds per market. GetValidMedianPrices() in the index price cache computes a median across exchange prices. The minimum number of exchanges parameter (per market config) ensures multi-source coverage — a market is only valid if enough exchanges have provided fresh prices. Not a single-pool oracle.
