But I was wondering if anyone has successfully switched their Brave Browser to receive BAT rewards on Metamask instead of Brave sending them to Gemini every month? does it work?
No, it doesn’t. You can only receive BAT to Uphold or Gemini at this time. They won’t pay Rewards directly to others, such as Metamask.
That article was written for people switching like from Uphold to Gemini or vice versa.
