Interesting, so this is I believe the same problem as all the Ethereum type stuff: you need to have it lives with your keys in the most horrific place in a computer, meaning a browser extension. Or put the web browser in the wallet. Either way, something like Metamask is really slow and scary.

The core Ethereum stuff is pretty elegant but once you want to build an UI you get trapped in hell to plug it to the "web".

Maybe the biggest problem of "Web3" is it was built on Web2.
