Calculation process

  •  Basically, during the exchange, we query the USD price as a reliable common point for both source and target currencies and calculate the result based on the exchange rate between something-USD and USD-something. 
  •  So, first, we convert the source currency to USD if it is not USD. If the source currency type is COIN, we query the USD price of the respective COIN from If the source is TOKEN, we search for swap pairs on where the source TOKEN is on one side, and we take the USD exchange rate from among those pairs with the highest liquidity. If the source is a FIAT currency different from USD, we query the exchange rate for the source FIAT from 

  •   We apply the same logic for the target currency, so we get the exchange rate in USD for both the source and the target currencies, and then calculate the result from these.
