HashKey Exchange Lists Matrixdock Gold XAUm, Enhancing Digital Gold Allocation Tools and RWA Asset Coverage

HashKey Exchange, the largest licensed virtual asset exchange in Hong Kong and a subsidiary of Hong Kong-listed HashKey Holdings Limited (3887.HK), has announced the listing of XAUm and opened over-the-counter (OTC) trading for professional investors. Trading pairs XAUm/USD, XAUm/HKD, and XAUm/USDT will go live on March 31, 2026, at 14:00 (UTC+8). Deposits and withdrawals are already available.

XAUm, an institutional-grade digital gold asset launched by Matrixdock, is fully backed 1:1 by physical gold. Each XAUm token represents one troy ounce of 99.99% pure physical gold held within the LBMA ecosystem and custodied in partnership with certified entities including Heraeus, Metalor, Brink’s, and Malca Amit. The underlying gold is stored in professional vaults in Singapore and Hong Kong, and physical redemptions are supported starting from a minimum of 1 kilogram.

XAUm emphasizes high standards of transparency in its product design. Monthly vault reports are published regularly and recorded on-chain; independent audits are conducted semi-annually by Bureau Veritas—the world’s largest gold ETF (GLD) auditor. Additionally, XAUm provides a holdings verification tool enabling token holders to independently verify their corresponding gold bar records.

Overall, XAUm preserves the intrinsic attributes of physical gold—such as store of value and safe-haven properties—while delivering enhanced liquidity and allocation efficiency through blockchain-based infrastructure, underpinned by full physical backing, periodic audits, and independently verifiable asset records.

Digital gold retains gold’s traditional risk-mitigation and value-storage functions while enabling on-chain transfer, fractionalization, and use as collateral in select lending and liquidity scenarios—offering professional investors greater flexibility in portfolio construction. For HashKey Exchange, this listing signifies an expansion beyond crypto-native assets into commodity-based real-world assets (RWAs), laying the groundwork for future integration of additional RWAs.

Michelle Cheng, Director of HashKey Exchange, stated: “Gold has long been a cornerstone asset in global portfolios. As real-world asset tokenization advances, demand is rising for digital gold solutions that combine transparency, verifiability, and efficient liquidity. The launch of XAUm enriches our suite of offerings for professional investors and reflects HashKey Exchange’s evolution—from a single-purpose trading venue toward a comprehensive digital financial services platform spanning trading, portfolio allocation, and broader asset servicing capabilities.”

For HashKey Exchange, XAUm represents more than just an additional trading pair. Recently, the exchange has advanced its institutional partnerships, fiat onboarding services, and capacity to support diversified asset classes. XAUm further strengthens the platform’s ability—within a regulated framework—to accommodate increasingly complex asset structures and higher-caliber capital requirements, reinforcing HashKey Exchange’s progression toward becoming a more complete digital financial infrastructure provider in Hong Kong.
