Banks play an essential role in the economies of countries. They attract customers' financial resources and provide them to applicants in various ways in the form of financial facilities. In this regard, the bank adjusts its financial relationship based on its ability and accreditation of facility applicants. However, the limitations of the bank in financing, as well as the complexity of banking relations and the risk of providing facilities to applicants have led to the design of a model to adequately fund and distribute the relevant risks. One of these financing methods is the provision of facilities in the form of a syndicate in which more than one bank is involved in providing facilities. syndicated Loans is done in the form of one of the bank contracts, so understanding the nature of bank contracts "subject to the law of interest-free banking operations" has a significant impact on determining the provisions related to this type of facility. In addition, the scope of review and the existence of various contracts and the volume of banking operations to pay for syndicated facilities doubles the need to use new financial technologies. High-potential blockchain technology can make a huge difference in a variety of areas, including financing, payment settlement, asset management, and even virtual assets. This application of blockchain is closely related to digital currencies and their use in exchanges. In fact, this platform not only plays an effective role in eliminating paper documents, but also improves the security of bank documents.
