Brave constantly polling sites in the background, please stop.

[notoriousturtle]

Description

Brave is constantly polling:

GET /data/price?fsym=ETH&tsyms=USD HTTP/1.1
Host: min-api.cryptocompare.com

and

GET /v2/blacklist HTTP/1.1
Host: api.infura.io

Web3 provider for dapps is set to none.

If I browse to brave://wallet it loads the new wallet page, with hardware wallet connector options.

Steps to Reproduce

Intercept traffic with a web proxy.

Expected result:

To not constantly poll anything.

Brave version (brave://version info)

1.5.115 Chromium: 80.0.3987.149 (Official Build) (64-bit)

Same here, even if crypto wallet and rewards are disabled - also I can see a lot of connections to api.infura.io.

So far I've blocked it directly on PiHole and after 1 day both domains appeared in Top Blocked Domains ;)

Version 1.7.92 Chromium: 80.0.3987.163 (Official Build) (64-bit)

[notoriousturtle]

Yeah, and some of those requests to api.infura.io are big!

I have also noticed this and honestly, I don't like it. I'm not using Crypto Wallet feature.

@BrendanEich can we get some movement on this?

[bsclifton]

@bbondy @ryanml I believe these are only reached if user visits brave://wallets page, right?

Unfortunately even if you are not enabling, just visiting the page I believe causes the extension to load

[snieg]

@bsclifton Nope, it's constantly polling min-api.cryptocompare.com & api.infura.io (even if you're not visiting brave://wallets).

Almost 1k requests daily:

[bsclifton]

@snieg correct - I think just visiting the page once activates the extension (and the extension may be polling those URLs)

Looks like @bbondy has a fix coming up with brave/brave-core#5513 😄

Moving to 1.10.x Beta as brave/brave-core#5624 is uplifted
