Given the importance and modernity of electronic money, and the legal and technical challenges it poses in the monetary and electronic field, this study shed light on the legal regulation of electronic money and related provisions and issues in accordance with Omani law and a number of European, Asian and African legislations. To achieve this goal, the researcher relied on the descriptive approach by dealing with legal texts and jurisprudential efforts related to electronic money, as well as using the analytical method to review the contents of legal provisions in Oman and a number of countries around the globe. The study starts with an introductory chapter dealing with a review of the historical aspects of money till to the stage of electronic money. The introductory chapter consists of two sections: the first section describes money in general, and the second is devoted to money in the Sultanate of Oman and the development of payment systems. Chapter one comprises four sections of the legal and jurisprudential provisions of electronic money regarding its nature, distinguishing from other payment systems and the obligations of the electronic money institution regarding this money. And the second chapter consists of two sections: one of which is devoted to electronic money issuance institutions, and the other explores the international experiences of central bank digital currencies. At the end, several results were reached, in addition to a number of recommendations that would contribute to strengthening the legislative structure in the Sultanate of Oman by fundamentally amending the National Payment System Law and its executive regulations, as well as a number of commercial laws.
