The Brave Team just announced they will be integrating Uphold wallet into the android app with a new launch coming this week.

What does this mean?
Android users can finally sync and transfer their BAT(Basic Attention Token) tokens earned through Brave Rewards with an Uphold wallet account. Holding BATs in an Uphold wallet allows you to reap the full benefits of all the tokens you earned via ads and tips. With a verified Uphold account users can then withdraw their BATs to an external wallet or convert it into 23 different fiat currencies and ultimately withdraw it to their bank accounts. Up until now only desktop users had that luxury. With Brave Rewards being completely separate on desktop and mobile, android and iOS users had very little use for the BAT tokens they earned aside from tipping content creators.
Until now...
Not only will android users be able to connect to an uphold wallet to withdraw their BAT earnings but they will also be able to sync their wallet from 3 different devices(including already verified desktop accounts). Meaning that if you have Brave Rewards enabled on 3 devices, all of the BATs you earn will be transferred to your Uphold wallet.
However, there is a slight change coming to Brave Rewards which will be implemented into the android version right off the bat(no pun intended). In order for users to verify their wallets and have their BAT balance transferred to their Uphold account, they must obtain a minimum 25 BATs in rewards. This will be effective immediately on android upon the launch and the change will come to the desktop version soon thereafter.
Fear not iOS users...
