According to Protos, Justin Sun's HTX exchange claimed to hold 360,949.90 USDS at a certain address in its September Proof of Reserves (PoR), but the address actually held 0 USDS at the block height corresponding to the PoR date (September 1). Additionally, HTX misrepresented its USDD holdings, claiming 44,975,772.00 USDD when the actual amount was 44,886,000 USDD. Protos noted that HTX had a similar issue in its May PoR, confusing the disclosure of different assets.
