The article analyzes the challenges facing regulators, financial organizations - participants in foreign economic activity and fintech enterprises. Approaches to the development of the cross-border payment industry have been systematized. The authors proposed a classification of models of cross-border payment infrastructure based on blockchain and ways to solve problems when making such payments by decentralizing the elements of this infrastructure. Recommendations are given to minimize the number of financial intermediaries in such payments and digitize their role using distributed ledgers, smart contracts and central bank digital currencies.
