Thanks for the suggestion.
I've tested Minibits, eNuts, cashu.me and Nutstash - Eventually settled with 0xchat's ecash wallet backed by my own mint 😉
I was more talking about having Nostr help drive the adoption of ecash itself in the form of zaps, just as it did with Lightning. ecash could potentially make more sense given the frictionless, smaller amount nature of zapping goes hand in hand with completely feeles transactions as well.
It's not lost on me that there are still a couple concerns around how large scale ecash would actually work, hence looking to experiment at a larger scale.
