Welcome to the community.

I’d like to follow this conversation, and I’d like to identify why these connections are being created and where these connections originate in the source code.

Do these connections generate a large amount of network traffic for you?

I have just started looking at this browser on Linux Mint (Ubuntu Xenial version) and notices that upon startup it downloads 15 - 20 MB of data without loading a page. Closing the browser and bringing it up again produces the same result.

At first I thought it was just downloading a Safe Browsing database but that should go to cache. For me this happens every time I restart the browser so it must only exist in RAM.

I’m on a slow connection so this is problematic for me.

I tried to find the domain names of the IP addresses you provided and most of them did not resolve. I did find that 40.115.22.134 belongs to cryptocompare.com, so I’m guessing it has something to do with the crypto-wallet. I wonder if you still get the connection if you don’t sign up for brave rewards?
