★ Empty cToken-style market (zero supply/borrow)
dYdX v4 (dYdX Chain)'s assessment for RD-F-070 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
dYdX v4 is a sovereign Cosmos-SDK perpetuals DEX, not a Compound V2 fork. No cToken-style lending markets exist. No share-based vault accounting of the Compound/cToken pattern is present. The empty-market donation-exploit attack surface does not exist on this protocol architecture. Per PD-024 (Compound-fork-only applicability) and taxonomy §Cat4 note. Two distinct-domain sources confirm non-Compound architecture.

Methodology #
Determine whether any listed Compound V2-fork market has `totalSupply == 0` and `totalBorrow == 0`, the precondition for a donation-exploit.
