I've read the whitepaper, and I'm not convinced. They're working on UX because they have funding from a foundation and are issuing a token. Of course, it's easier to do anything when you're a company that can hire people because you did a premine.
Another point is using the browser as a node. I'm pretty skeptical about this, and we have a bunch of examples like IPFS that show it won't work at scale for verification, at least not today. Maybe in the future, but not now.
Suggesting Bitcoin needs a middleman is a lie and unethical. People can choose to use a middleman, but they can also run everything themselves. And the tech is evolving to improve usability, like Phoenix, Zeus, Mutiny, etc. Soon we'll even have a Bitcoin Core mobile app.
Their integration with Bitcoin is just an app doing swaps. They don't work with the native BTC token either.
So, I really think they're just another project trying to gain traction in the market by misleading people about a problem that is not real.
