★ Empty cToken-style market (zero supply/borrow)
Babylon Protocol'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 #
NOT APPLICABLE — N/A by construction. Babylon is not a Compound V2 fork. No cToken-style markets, no totalSupply()==0 empty-market conditions, no ERC-4626 share accounting. BTC is locked in Bitcoin Taproot UTXO scripts; Genesis chain uses Cosmos SDK x/btcstaking module (delegation registry, not share minting). The classic donation-attack / share-inflation vector does not exist. ★ critical factor does not fire. Taxonomy PD-024: Compound-fork-only factor.

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