Abstract: This article attempts to systematize all currently existing at the EU level areas of supranational regulation of public relations in the digital sphere. An appropriate systematization can be useful both from the point of view of further theoretical understanding of supranational regulation at the present stage, and from the point of view of using the EU experience to harmonize the regulation of the digital space within the EAEU. Despite the fact that, individually, almost all areas of supranational regulation have become the subject of research, their cumulative, systemic effect has not been analyzed. This predetermines the scientific novelty of the present study. In addition, the scientific novelty of the article is also manifested in the fact that the author involves in scientific circulation the most relevant areas of supranational legal regulation of social relations arising in the digital sphere (in particular, we are talking about supranational regulation of artificial intelligence and crypto assets). In this article, based on an analysis of the EU experience, a general conclusion is made that supranational regulation of social relations in the digital sphere today has significantly expanded (and continues to expand) due to the inclusion of fundamentally new areas of public life that have arisen in connection with the development of information and communication technologies. In addition, the article carried out a detailed systematization and classification of the key areas of supranational regulation of social relations arising in the digital sphere.
