In cross-border trade financing, problems such as difficulty in authenticity verification, low efficiency in business handling, repeated financing, and difficulty in supervision will eventually increase the financing cost of enterprises. The lack of substantive verification of the authenticity of the trade background and the neglect of risk control have led to an endless stream of trade financing fraud cases and even financial crimes
