Objective: to assess the Russian legislation for its compliance with the international-legal approaches to shaping symmetrical regulation of crypto-assets and possibility to complement it with new internationallegal categories reflecting the in-depth changes in the global economy and structure of international finance, determined by the broad introduction of new financial technologies based on distributed ledger technologies.Methods: the methodological basis of the research is a set of general scientific methods of scientific cognition, among which of utmost importance are special-legal (formal-legal and comparative-legal) methods, complemented with risk-oriented approach, legal modeling and juridical forecasting. Applied integrally, they allowed comprehending the architecture, “letter and “spirit” of the modern international financial law and national legislation in their conceptual-terminological correlation and to forecast further development and adjustment of the legal regulation of crypto-assets turnover.Results: it was found that there appears a stable trend in the crypto-assets turnover regulation, according to which “soft” law dominates among the law sources (this is especially notable in the sphere of international financial law compared, for example, with conventions or international treaties); at the same time, there is a strengthening trend of “fragmentation” of international law with regard to crypto-assets turnover; the authors mark inconsistency of the conceptual framework contained in international acts and in the Russian legislation, as well as the gaps in the regime of crypto-assets turnover at the level of national law; the trends and forecasts are presented referring to the development of international-legal regulation of the sphere of crypto-assets.Scientific novelty: consists, first of all, in a complex comparison, based on, among other aspects, the fundamentally new concepts of regulation of such progressive international-legal categories as cryptoasset, virtual asset, cryptocurrency, stablecoin, etc., some of them rarely used in the Russian legal discourse and actually never applied in legislation.Practical significance: the scientifically grounded proposals are formulated, aimed at improving the conceptual-terminological framework of the Russian legislation in the sphere of crypto-assets turnover, implementation of which will allow constructing a common legal space with the technologically most advanced states, will help to improve investment climate and financial attraction of the state; will improve the national-legal regime of crypto-assets turnover from the viewpoint of not only actual market demands, but also state security interests and improving competitiveness of the Russian legislation.
