HashKey Exchange, Hong Kong's largest licensed virtual asset exchange under HashKey Holdings Limited (3887.HK), a Hong Kong-listed company, has announced the listing of XAUm and the opening of OTC trading for professional investors. The XAUm/USD, XAUm/HKD, and XAUm/USDT trading pairs will open for trading on March 31, 2026 at 14:00 (UTC+8). Deposits and withdrawals are now available.

As an institutional-grade digital gold asset launched by Matrixdock, XAUm is backed by a 1:1 allocation of physical gold. Each XAUm corresponds to 1 troy ounce of 99.99% pure physical gold. The related gold assets are located within the LBMA ecosystem and collaborate with certified partners such as Heraeus, Metalor, Brinks, and Malca Amit. The underlying gold is held in professional vaults in Singapore and Hong Kong, and physical redemption is supported from a minimum of 1 kilogram.

XAUm emphasizes high standards of transparency in its product design. Its monthly vault reports are published regularly and recorded on the blockchain; it is audited every six months by Bureau Veritas, an international inspection and certification agency that also audits the world's largest gold ETF, GLD; in addition, XAUm provides a holdings query tool, allowing token holders to independently verify the corresponding assets based on the underlying gold bar records.

Overall, XAUm, through its fully allocated physical assets, regular audits, and independently verifiable underlying asset records, retains the attributes of physical gold assets while also possessing higher circulation and allocation efficiency for on-chain assets.

Digital gold retains the safe-haven and store-of-value properties of gold while also allowing for on-chain transfer and splitting, and serving as collateral in certain lending and liquidity scenarios, providing professional investors with more flexible asset allocation options. For HashKey Exchange, this launch signifies that the platform's asset portfolio is expanding from native crypto assets to real-world commodity assets, laying the foundation for accepting even more real-world assets in the future.

Michelle Cheng, Director of HashKey Exchange, stated, “Gold has long been one of the core assets in global asset allocation. As the on-chaining of real-world assets continues to advance, market demand for digital gold tools that combine transparency, verifiability, and efficient circulation is rising. The launch of XAUm enriches the asset selection available to professional investors on the platform and demonstrates that HashKey Exchange is moving from a single trading scenario to a digital financial services platform that covers trading, asset allocation, and a wider range of asset acceptance capabilities.”

For HashKey Exchange, XAUm represents more than just adding a new trading instrument. Recently, HashKey Exchange has been continuously advancing its institutional partnerships, fiat currency services, and capabilities to support more diverse assets. The launch of XAUm further strengthens the platform's ability to handle more complex asset types and higher-quality funding needs within a compliant framework, allowing HashKey Exchange to continue its journey towards a more complete digital financial infrastructure as a licensed platform in Hong Kong.
