Prometheum Capital, HashKey, and Velocity Capital have signed an MOU to support qualified overseas investors in trading US stocks, ETFs, and government bonds in tokenized form through the HashKey exchange. According to The Block, these tokens are securities held at the DTC (Depository Trust Company) and will connect Prometheum's regulated custody and trading infrastructure with overseas cryptocurrency market distribution networks and the upcoming DTCC tokenization service. The project must undergo final contract signing, regulatory approval, and technical integration processes. The DTCC tokenization service is expected to launch in Q4 2026.
