The authors have carried out an analysis of the main e-commerce categories, the content of which is standardized in regulatory legal acts, including the elements of the purchase and sale process, the concept of types of trading activities, electronic signature, digital assets, digital currency, smart contracts, digital transactions, etc. The article defines the categories, the concept of which is absent in the regulatory legal acts of Russia: the concept of digital goods, e-commerce infrastructure, electronic trade services, delivery channels in online stores, the concept of a courier/courier service, the concept of smart applications, definition of online stores varieties, and so on. Conclusions have been made that the digitalization process has a significant impact on the dynamics of the legal support for the development of electronic commerce, but currently its level is not sufficiently high and requires improvement (by making additions to GOST on trade, the Strategy for the development of electronic commerce and other regulatory legal acts).
