[Prometheum Capital, HashKey, and Velocity Sign Binding Memorandum of Understanding to Promote Tokenized U.S. Stocks in International Markets] BlockBeats News, September 16: Crypto asset market infrastructure provider Prometheum announced that its subsidiary, Prometheum Capital, has signed a binding memorandum of understanding with HashKey Digital Asset Group and Velocity Capital to jointly promote the entry of tokenized U.S. stocks into international markets. The parties plan to leverage the infrastructure of a securities broker-dealer registered with the U.S. Securities and Exchange Commission (SEC) and distribute related products to qualified international investors through HashKey's licensed trading platforms operating in multiple jurisdictions. Prometheum Capital and Velocity will provide HashKey with custody, trade execution, and clearing services for both traditional securities and crypto assets, while HashKey will handle international distribution. The tokenized U.S. stocks will serve as "digital twins" of traditional stocks, with the underlying stocks held in custody by the Depository Trust Company (DTC), rather than using synthetic assets or offshore wrapper structures. DTC's tokenization services are expected to launch in Q4 2026, with eligible assets including Russell 1000 Index constituents, ETFs tracking major indices, and U.S. Treasury bonds. The three parties will negotiate a final agreement and complete technical integration in the coming months. The related business operations remain subject to regulatory approval, with plans to initiate a pilot project thereafter.
