HashKey Group said Sept. 2 that it had joined the Depository Trust & Clearing Corporation’s Digital Assets Advisory Services Industry Working Group as its first Asian digital asset service provider. The Hong Kong-based company will contribute Asia Pacific regulatory and operational experience to discussions on standards for issuing, transferring, settling and safeguarding tokenized securities. HashKey said the group now includes more than 100 financial institutions, asset managers and digital asset companies, naming JPMorgan Chase, Goldman Sachs, Nasdaq and the New York Stock Exchange among its participants. DTCC’s own May announcement identified more than 50 organizations; the higher figure appears to reflect later additions, although DTCC has not published an updated complete membership list. DTCC formed the advisory group to help develop a tokenization service that would let DTC participants create blockchain-based representations of eligible securities already held in custody, transfer them to approved wallets and convert them between conventional and tokenized formats. DTCC completed production transactions in July involving equity transfers, collateral pledges, securities lending and delivery versus payment transactions for U.S. Treasuries and repurchase agreements across a private blockchain based on Hyperledger Besu and the public Canton Network. The tests involved securities including Microsoft and Circle shares, the Invesco QQQ Trust, the SPDR S&P 500 ETF and a BlackRock Treasury exchange traded fund. DTCC plans to introduce standardized tokenization services in October 2026, initially with compliance and distribution controls. HashKey’s participation is advisory and does not constitute regulatory approval, DTC membership, guaranteed commercial access or a separate integration or commercial agreement.
