The article is devoted to the analysis of the legal regulation of the process of introducing FinTech in the sphere of impact finance within the context of digital technologies in the newly expanded BRICS bloc. This is a crucial step in order to be able to meet the challenges of the new global digital economy and cooperate in achieving common goals. The authors come to the conclusion that although the BRICS countries are geographically located on different continents, the states that decided to form this organization share a number of key features. Firstly, the governmental role in the digital transformation of all BRICS countries is significantly greater in comparison to the Western countries. Secondly, because not all BRICS countries have developed economies, the BRICS member states, despite their strong interest in digitalization of their countries, do not always have the capacity to finance such projects from their own national budgets, which highlights the important role of the BRICS New Development Bank in the process of digitalization of the BRICS economies. Thirdly, cooperation among the BRICS countries, through their participation in the New Development Bank in the digital realm, can significantly contribute to fostering the economic growth of each country within the integration. Since the greatest effect of digital technology penetration is achieved when starting from the lowest level, harmonization of approaches in the BRICS countries and new member countries of the bloc will most likely have a synergistic effect.
