Prerequisites:

• You already have some IOTX

Steps

1. Open the exchange website

   In this guide we'll be using Intercambio.app.
   
   Simply click on "Intercambio.app" to open it.

2. Perform the exchange

   Select the currency you'll be exchanging from on the left, so in this case IOTX, and the one you'll be exchanging for on the right, in this case FIS.
   
   Input the amount of IOTX you want to sell for FIS, paste the receiving address for your FIS after the trade is done and click "TRADE".
   
   Finally send the amount of IOTX to the address that shows up on the screen by either copy-pasting the address shown on the page into your wallet or scanning the QR code on the right.

3. Sit back and wait

   Make sure to note down the Trade ID shown on the page in case of issues with the trade.
   
   Transactions can take a while to complete (often as long as an hour) so be patient.
   
   If you encounter any issues contact Intercambio.app customer support with your Trade ID.
