★ Empty cToken-style market (zero supply/borrow)
Orca'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 #
RD-F-070 ★ CRITICAL — not_applicable. Orca Whirlpools is an original open-source Anchor/Rust CLMM on Solana; it is NOT a Compound V2 fork and has NO cToken-style market accounting, no totalSupply/totalBorrow market state, and no borrow-enable lifecycle. The donation-exploit vector (zero-supply cToken market + direct token donation inflating exchange rate) has no structural analog in Whirlpools' reserve-based pool accounting. Pre-marked not_applicable in the phase-2 briefing and consistent with PD-024 Compound-fork-only designation in the taxonomy.

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