In brave browser BAT you can sync settings & bookmarks saved in the browser that claims to be decentralized non custodial so how is that possible then?
Just so you know, brave browser isn't decentralized. If you want to prove this, just try claiming the BAT rewards they send you and see if they won't ask for KYC.
Brave lost its credibility a long time ago when they became too greedy for money and got acquired by Binance.
