Google can trackers on defi sites can see your wallet addresses and track all of your transactions. Brave blocks this.

56% of defi sites have Google trackers that can see your crypto wallets and tie them to your Google accounts (and therefore your tx history if you aren't using Monero and Secret Network for all of your defi).

Brave has an elaborate method of blocking that by default. Don't let Google have your financial records for free. They don't need your data donations. Download Brave and tell Chrome to get a job. Brave has all of the same extensions available, but is a faster browser because it isn't bloated with trackers. Also, it let's you listen to YouTube videos with the screen off- just like you used to be able to do before Google started paying browsers to disable that so they could sell you crap.
