★ Empty cToken-style market (zero supply/borrow)
USDD (Decentralized USD)'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 #
USDD is not a Compound V2 fork. It is an original CDP stablecoin issued on TRON (TVM). No cToken market architecture exists. The empty-market/donation-attack pattern is specific to Compound V2 fork lending protocols with share-based accounting. The USDD PSM and CDP mechanism use 1:1 fixed-rate conversion, not share-price accounting. PD-024 Compound-fork-only N/A confirmed.
