To trade cards in Monopoly GO!, start by launching the game on your device. Once the game is open, tap the ‘Album’ symbol at the bottom right corner of the home screen. This will take you to your card collection.
Next, select the card you want to trade. If you have duplicates of a card, they will be marked with a ‘+’ sign. After choosing a card, tap the ‘Select a Friend’ option and pick the friend you want to send the card to from your friend list.
Finally, tap the ‘Send’ button to send the card to your friend. Your friend will get a notification and can claim the card when they log in. It’s important to note that you can only trade cards with friends who have accepted your friend request.
Keep in mind, you can only trade up to 5 cards each day. Also, gold cards cannot be traded unless a Golden Blitz event is active. Make sure to plan your trades wisely!
