I was going to say something similar
Zeus imo is way ahead of the game.
They have NWC, ecash, your own self custody lightning channels, and on chain.
All in one easy to use app. And when your ecash stack gets too big it automatically prompts you to sweep sats into self custody
Imo ecash is more private and offline payments is a big deal. Zeus is leading the way!!!!!
I love ecash
It’s just sats
You can send ecash sats to a lightning wallet- and you can send lightning sats to an ecash wallet… it’s just sats
