1. Go to the non-Everex wallet address that you want to add in Everex wallet's contact. Copy it.
2. Then you go to Everex app. Tab "Send" and you can add it by tabbing “Add New Contact” then paste the copied wallet address.
Remark: The system will show "Not Everex address" which is fine. The system just warns you that the wallet address that you provided isn't address of Everex user.
