Here at ZBD, your Gamertag is the same as your Lightning Address. Here's how to find it:
Open your ZBD App.
Your Gamertag and Lightning Address is in the gray box above your balance.
Tap on the gray box to edit your Gamertag or copy it to use elsewhere. When you edit your Gamertag, it will automatically change your Lightning Address to match it.
ZBD Tip: If you tap it, you can easily copy it for use anywhere you need.✨
