The article tackles the emergence and spreading of digital agroinstumental-start-ups (such as "grain" tokens in Latin America and other countries, as well as unions, such as EAEU and BRICS) in the international economy, and explores key parameters of the so-called tokenomy. It expounds on the broad spectrum of start-up companies, evaluates the feasibility of their transformation into "unicorns" and looks into the legal basis and regulations which may serves as the foundation for application of similar approach within the institutional expertise of the EAEU and BRICS members. The Eurasian track-record is revealed on the outcome of "grain" token application in Kazakhstan and Belarus, with particular emphasis on the peculiarities of token operational effectiveness in Kazakhstan. The article also considers the original pilot project of grain tokenization in Russia, launched by the Rosselkhozbank start-up. The authors outline the importance of digitalization in the agro-industrial complex, as it leads to greater opportunities for its structural development and broader capitalization. The following conclusion is derived: utilization of tokens in the current environment plays a crucial role not only in the mobilization of additional resources, but as a natural substitute for fiat foreign currencies in the international payments between the BRICS members. The presented line of research appears essential for the implementation of the national agricultural food security of the population of the Russian Federation.
