Star Chain, a cryptocurrency concept stock, announced it will suspend trading on the Hong Kong Stock Exchange starting November 26, following concerns over its ability to meet continuous listing requirements. The announcement led to a 73% drop in its stock price on November 17. The exchange cited Star Chain's failure to maintain sufficient operational levels and lack of substantial assets as reasons for the suspension under Listing Rule 13.24. Formerly known as Leading Pharma Biotech, Star Chain rebranded in September 2025. In October, the company signed a memorandum with Starcoin Foundation to issue Starcoin tokens, planned for deployment on Conflux eSpace. Notably, Conflux founders Long Fan and Wu Ming previously served as executive directors at Leading Pharma.
