I have seen most blockchain teams not be very good at “classic web” technologies.

How many CRYPTOPROJECT.herokuapp.com sites are there for Slack invites, where seemingly the team can’t get it together to map a domain name to the Heroku platform? (takes maybe 5 minutes)

But that’s a digression. I don’t think building desktop apps fixes security at all.

Random apps – without knowing if they’re secure or not – downloaded to your Mac or Windows desktop? Where they have full access to everything on your machine? No, that’s not more secure.

For less technical end users, a mobile app on iOS or Android downloaded from the official App Store is likely the most secure.
