Swash is a microrewards service through an extension, with which you can offer your data while browsing, to be sold on the Streamr network for DATA tokens (they live on the Ethereum network, just like BAT). You can set up the level of privacy:
- sending a bit more personal, but not personally identifiable data, including full URL, exact access time, etc
- turning some of that into hashed values, masking some, while opting out others
- opting out everything, except the root URL, and obfuscating the access date.
The default setting upon the installation and configuration of the extension is the mid-level privacy. The lower, the more valuable the metadata. I have it set to high level privacy. Less DATA earned, but hey, I want to control it, ok?
You can also specify the collected info for various websites and services, like Amazon, search (it includes Google, obviously, Bing, even Baidu, and even DDG), Facebook, Twitter, Spotify, YouTube.
You get a wallet created by the extension, and you get to have the private key (not the seed phrase). You can import your wallet into any other wallet that does that via the private key (eg. Brave, and its fork-parent Metamask).
You can read more about them on their website, I think it’s a neat idea: https://swashapp.io/
