Wu said that the Hong Kong Securities and Futures Commission today issued a circular to all licensed virtual asset trading platforms, clarifying the minimum standards for custodian clients' virtual assets and good operating examples, covering areas such as cold wallet facilities, third-party wallet usage, real-time monitoring, and executive responsibility. This move aims to respond to recent overseas custodian loophole incidents and implement the goal of safeguarding client assets in the 'ASPIRe' roadmap.
