"Cryptocurrency" (Ramzpul) is a term that entered the country's economic and legal literature with the implementation of the Central Bank of the Islamic Republic of Iran Act in 2024. With the emergence of the concept of cryptocurrency, disagreements arose regarding its definition, scope, the institution in charge of its supervision and regulation, as well as its relationship with concepts like crypto-asset, digital currency, and the digital Rial. This has led to the failure to establish an efficient regulatory system in practice. This article, adopting a descriptive-analytical approach, aims to examine the concept of cryptocurrency and its relationship with other similar concepts. By referring to the text of the country's current laws and regulations, it seeks to answer the question of how the legal system of our country has been organized in the field of regulation and supervision of cryptocurrencies. Ultimately, the finding of this article is that the definition of this concept in the Central Bank Act is a broad definition that encompasses the majority of today's recognized crypto-assets. Consequently, all of these fall under the supervision and regulation of the Central Bank and the provisions and rules of the Central Bank Law; a matter that is entirely consistent with the inherent function of these cryptocurrencies in Iran's current economy and the Central Bank's missions. Accordingly, the intervention of other bodies in this area and the Central Bank's refusal to perform its legal duties lack legal justification.
