Prerequisites:

• You already have some CRO

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 CRO, and the one you'll be exchanging for on the right, in this case GRT.
   
   Input the amount of CRO you want to sell for GRT, paste the receiving address for your GRT after the trade is done and click "TRADE".
   
   Finally send the amount of CRO 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.
