I’m sure it says somewhere but i could not find out what version of chrome(chromium?) brave is based on while trying to find this out for maybe 5 minutes. So, just to be sure i am not installing an browser with known vulnerability I’ll stick with chrome for now.
If you look at README in the repo [1], it says that the Chromium version can be found in `package.json`, currently 90.0.4430.61, released 4 days ago [2].
It does. Brave adds it's own code on top. Like injecting affiliate id's on some links. The affiliate programs (Binance, Coinbase, Ledger, Trezor) allow Brave to view a detailed overview of purchases made.
