According to TechFlow, Hong Kong Monetary Authority Deputy Chief Executive Chen Weimin wrote in Huisi that the main application scenarios proposed by the first batch of institutions participating in the "Sandbox" include payment, supply chain management and capital market use cases. In addition, there are other use cases such as Web3, games and virtual asset trading. Entering the "Sandbox" is not a prerequisite for applying for a license in the future. If interested in obtaining a license, participating institutions need to submit a formal application after the regulatory system is implemented.
