XAUa, a tokenized gold regulated in Hong Kong, has been launched on Sui. The token is minted based on Sui's Permissioned Asset Standard (PAS), issued by AlphaToken, and distributed by TBook. Each XAUa is backed by physical gold stored in Hong Kong, and holding and purchasing it are subject to eligibility requirements. In accordance with PAS rules, issuers incorporate compliance rules into their policies, and each transaction must pass policy verification before settlement. TBook has migrated its vault issuance platform to PAS, allowing RWA issuers to subsequently issue vaults with similar compliance controls on Sui.
