Currency in accounting

Accounting in the system is always performed within one Currency. If several USD are created in the system as different currencies they are considered different currencies because they have different IDs. So, if it is required to move issued electronic money between different Currencies, top-up/withdrawal or exchange operations are used. 

For this purpose, the currency exchange rate can be set up as 1. 

Another example, if it is required to perform a transfer from wallet 1 in currency USD with ID 1 to wallet 2 in currency USD with id 2, the following operations should be done: 

  • exchange operation if both wallets belong to the same user 
  • exchange – transfer – exchange if wallets belong to different users
  • or withdraw – top-up if wallets belong to different users
