I wondered how they are working, like the process from receiving the payment to exchanging and sending the exchanged crypto.
Steps on using this kind of exchange is simply just 1,2,3. Everything that can be seen on the screen are just as it is, like:
- entered the amount
- choose coin you have
(the one you will send later)- choose coin you want to receive or "exchange"
- click "next" or "proceed" or "exchange" button or anything they use
- then it will generate a receiving address where you will send the coins that you have. Sometimes it shows there the total coin you will receive after the exchange, the fees they take, the average/recommended fees you will use to transfer.
There are some helpful videos on how to use these instant exchange actually, just use google.
About the process, there's no exact answer unless they will show their backend source code process. Jut simply follow the steps above and understand it. It all works with webhooks and api. The page displays on when you entered amounts are the trigger of these. It will start after you send the exact coin/amount and token/coin to the receiving address, after confirmation, their system will trigger that it receives the exact amount then process the sending of the chosen coin to be received. Of course those coins listed they have to be sent/exchange have enough balance on their own hot wallet or else you will receive an error after you entered high amount.
