HashKey Holdings Limited (3887.HK), a listed company in Hong Kong, announced the launch of XAUm on HashKey Exchange, the largest licensed virtual asset exchange in Hong Kong, and opened OTC over-the-counter trading for professional investors. The trading pairs XAUm/USD, XAUm/HKD, and XAUm/USDT will open for trading on March 31, 2026, at 14:00 (UTC+8), and the deposit and withdrawal functions are now available.

As an institutional-grade digital gold asset launched by Matrixdock, XAUm is supported by fully allocated physical gold on a 1:1 basis. Each XAUm corresponds to 1 troy ounce of physical gold with a purity of 99.99%, and the relevant gold assets are located within the LBMA ecosystem, collaborating with certified partners such as Heraeus, Metalor, Brinks, and Malca Amit. The underlying gold is stored in professional vaults in Singapore and Hong Kong, and physical redemption is supported starting from a minimum of 1 kilogram.

XAUm emphasizes high-standard transparency in product design. Its monthly vault reports are regularly published and recorded on-chain; audits are conducted semi-annually by the international certification body Bureau Veritas, which is also the auditor for the world’s largest gold ETF, GLD; simultaneously, XAUm provides a holding inquiry tool, allowing token holders to independently verify the corresponding assets based on the underlying gold bar records.

Overall, XAUm retains the attributes of physical gold assets while achieving higher liquidity and allocation efficiency of on-chain assets through fully allocated physical backing, regular audits, and independently verifiable underlying asset records.

Digital gold, while retaining the hedging attributes and store of value function of gold, can also be transferred and split on-chain, and used as collateral in certain lending and liquidity scenarios, offering professional investors a more flexible allocation method. For HashKey Exchange, this launch also signifies that the range of assets it can handle is extending from crypto-native assets further into commodity-like real-world assets, laying the groundwork for the future handling of more real-world assets.

Michelle Cheng, Director of HashKey Exchange, stated: “Gold has long been one of the core assets in global capital allocation. As the on-chain transformation of real-world assets continues to advance, the market demand for digital gold tools with transparency, verifiability, and liquidity efficiency is on the rise. The launch of XAUm enriches the asset choices available to professional investors on the platform and reflects that HashKey Exchange is evolving from a single trading scenario into a digital financial service platform that covers trading, allocation, and a wider range of asset handling capabilities.”

For HashKey Exchange, the significance of XAUm goes beyond adding a new trading target. Recently, HashKey Exchange has been continuously advancing in institutional cooperation, fiat services, and more diverse asset handling capabilities. The launch of XAUm further strengthens the platform’s ability to handle more complex asset forms and higher quality capital demands within a compliant framework, allowing HashKey Exchange to continue progressing toward a more complete digital financial infrastructure on its licensed platform in Hong Kong.
