In contemporary commerce, digital currencies and related trademarks have become an integral part of economic life and are increasingly subject to international legal scrutiny. The global community, therefore, requires comprehensive legal frameworks to ensure transparency, accountability, and effective regulation of transactions in this domain. International organizations, as key actors in the international legal order, bear a crucial responsibility in shaping these frameworks. Their role in developing new rules and standards is essential to address the emerging challenges posed by digital currencies and cryptographic technologies. Adopting a descriptive-analytical approach, this article examines the regulatory efforts of international organizations in the field of digital currencies and seeks to answer the central question: What role do international organizations play in the formulation of rules governing digital currencies and cryptographic transactions? By analyzing founding documents and the existing practices of international organizations, the study concludes that these institutions possess both the mandate and the capacity to establish rules regulating digital transactions. Such regulation is indispensable not only for maintaining the integrity of international commercial exchanges but also for safeguarding the political and institutional legitimacy of international organizations themselves.
