If you have Uphold and go to link your account, you need to go to your Profile in Uphold and provide all of your information. Like I said, instead of a generic “New York” or “Shanghai, China” or whatever, you’d need your entire house address. Such as 123 Happy Ave Somewhere, IN 12345
So it means putting your “full name” (First and Last anyway), your Date of Birth (month/day/year), SSN/TIN (complete number), entire address (like if I wanted to send you something in the mail, all the details needed), and your email address.
If that’s not all filled out, then it won’t appear to Brave you’ve been verified. Uphold can be content because they’ll ask you to send documentation to them, such as a copy of your ID that has your address and all. But if the Profile doesn’t have all that info, then it won’t communicate that with Brave and they’ll say you haven’t done all that yet. Thus you wouldn’t be able to successfully link your Uphold with Brave until it’s done.
