Can you elaborate more @VirajRana? I’m still unclear about your issue.
Did you mean that your channel is not shows verified status when you see it via Rewards panel (BAT triangle icon at URL bar)?
Basically, once you finish adding your site/channel and you can see it’s listed under your publisher account, then it’s verified.
Your Brave require 24-48 hours to sync with latest publishers list. If it’s still shown unverified see Solutions for “not yet verified” bug
