Design should capture and express the essential properties of a product/technology. If users can't tell the difference between self-custodial and custodial bitcoin apps, then we're doing it wrong.
Especially open-source community-led projects are well-positioned to provide unique user experiences that companies and custodial solutions cannot offer due to their different goals, structure and incentives.
What do you think of bitkey app if you’ve tried it.
I like it, it's really well done (tested the beta app thoroughly). Just have to keep in mind who it's for. It costs $150, so it's only economically worth it above certain amounts. Screenshots on the site show balances of over $7,000 and transactions of $50+, which seems appropriate for an on-chain only product (assuming you don't want fees to be above a certain percentage of amounts). You get a really well-thought out security model and recovery service, and a nicely executed UX that doesn't bother you with technical stuff. So if that fits your needs, it's a great product.
