Therefore, any attempt to reduce time or cost increases credential efficiency. The purpose of this article is to explain the possibility of transferring letters of credit procedures from previous methods to the blockchain platform and creating smart contracts as model proposals, using the descriptive analysis procedure to coordinate and evaluate the steps in both procedures. Deals in this area and its compatibility with block chain technology and smart contracts. The results of this study show that implementing a Letter of credit on the block chain platform as a system that is highly secure and uses smart contracts (self-execution) increases transaction security and the likelihood of retaining provided documents, resulting in human resources involvement and the process from beginning to end credit makes documents shorter, faster and low cost. Usance LC on the block chain platform is also based on smart assets, eliminating the need to comply with Swift and FATF rules, including issues such as the lack of direct lines between banks in different countries.
