TBook Documentation Lists XAUa on Sui as a Token Representing One Gram of Gold
Key Facts
TBook has listed the XAUa token in its asset catalogue on the Sui network, providing a digital channel for the gold product Yunfeng Financial launched in Hong Kong for professional investors in May 2026. The platform’s documentation identifies Sui as the token’s native chain and says the catalogue displays the assets enabled for each institution. XAUa transactions require the wallet to be whitelisted, according to TBook documentation. The documentation does not say access is restricted to institutions, nor does it describe the product as licensed or regulated by a Hong Kong regulator. The listing comes as authorities work to expand gold-trading infrastructure and develop rules for tokenized real-world assets.
Each unit of Yunfeng’s product represents one gram of physical gold with a purity of 99.99%, held in vaults in Hong Kong, according to Caixin Global’s coverage of the launch in May 2026. TBook documentation defines XAUa’s physical unit as the gram, linking the token to a specified quantity of metal. Caixin said the product was not available for trading on a secondary market at launch. The product as offered in Hong Kong is therefore distinct from an asset freely tradable on a secondary market, while TBook documentation confirms its availability in an institutional catalogue on Sui. AlphaToken provided the blockchain infrastructure for Yunfeng’s product, Caixin reported; the sources do not establish that AlphaToken launched a new token issuance when it was listed on TBook.
The product reflects a broader push to develop tokenized commodities. Caixin’s summary reported that the tokenized commodities market reached $5.5 billion in the first quarter of 2026, while trading in tokenized spot gold reached $90.7 billion over the same period. These figures place Yunfeng’s product within wider market activity in gold and digital commodities, but do not measure XAUa’s size or trading. In Hong Kong, the government began a pilot operation of a central clearing and settlement system for over-the-counter gold transactions on July 7, 2026. The system was presented as part of initiatives to build an integrated gold-trading ecosystem, including the infrastructure needed to settle transactions. This follows Yunfeng’s product launch in May, while XAUa’s listing on TBook enables its use through digital infrastructure based on Sui.
On policy, a Hong Kong government official said the Securities and Futures Commission would improve the regulatory framework to facilitate the issuance and trading of gold products and other suitable tokenized real-world assets on licensed platforms. The government announcement links this work to trading on licensed platforms, without establishing that Yunfeng’s product or the XAUa token is licensed under a new framework. The government aims to formally launch the central clearing and settlement system for over-the-counter gold transactions in the first quarter of 2027, following its pilot operation and connection to the real-time gross settlement system. That target sets the next step in developing the infrastructure whose pilot began in July 2026. Regulatory improvements and the planned clearing system would form part of Hong Kong’s efforts to build a broader tokenized-gold market, while secondary-market trading in Yunfeng’s product remains unavailable according to the description at launch.
