@k00b @ek continuing from the thread, here is one rough idea about how you could bring this to the user's attention in the UX and motivate attachment of wallets and illustrate what it means.
The "attach wallet" page is quite complex for someone who does not know much (what does NWC, LNC, and LNBITS mean to a newbie?) so there could be some useful tooltips, alerts, or recommendations in there too.
I am sure you guys are onto it, but happy to throw in some design feedback as you work through it!
