1. It all starts with this design.{"version":"1.3"}

2. Specify a list of currencies. It must consist of pairs in the format "currency code: currency number". The currency number cannot be 0 and must consist of digits from 1 to 0.
{"version":"1.3","currencies":{"list":{"1":"PMUSD","2":"BTC","3":"ETH"}}}

3. The next step is to specify the exchanges. As shown in the example, all exchanges must be listed in the following exact order: exchange -> incoming currency code -> to -> outgoing currency code.
{"version":"1.3","currencies":{"list":{"1":"PMUSD","2":"BTC","3":"ETH"}},"exchange":{"1":{"to":{"2":[],"3":[]}},"2":{"to":{"1":[]}},"3":{"to":{"1":[]}}}}

4. Every course must be a multiple of 1; that is, either 1 = X or X = 1, where X must be a number greater than or equal to 1. There are two ways to specify the exchange rate in the file: the short form and the extended form. Use the short form if no information other than the exchange rate needs to be specified. In all other cases, use the extended form.
{"version":"1.3","currencies":{"list":{"1":"PMUSD","2":"BTC","3": "ETH"}},"exchange":{"1":{"to":{"2":-57.8,"3":8625.983721}},"2":{"to":{"1":{"xr":60}}},"3":{"to":{"1":{"xr":-8594.7463}}}}}

5. Currency reserves, like currencies, are also listed in a list. The list must consist of currency code: reserve pairs. For the currency code, you must specify the code under which the currency appears in the currency list. For the reserve, specify the amount of currency available for exchange. Sometimes it is necessary to specify an individual reserve for a specific exchange; in this case, it should be specified in the amount field in the details for that exchange, as shown in the example below.
{"version":"1.3","currencies":{"list":{"1":"PMUSD","2":"BTC","3": "ETH"},"amounts":{"1":945.54,"2":12500,"3":0.67231509}},"exchange":{"1":{"to":{"2":-57.8,"3":8625.983721}},"2":{"to":{"1":{"xr":60,"amount":300}}},"3":{"to":{"1":-8594.7463}}}}
