enuts also has a sweet "swap mint" function under mint management that allows you to move funds to a different mint in enuts. All ecash can be "melted" to your self custodial lightning wallet if you choose. 

minibits functions as a custodial lightning wallet where the balance is kept as ecash - the ln bridge is both ways

you can receive ln payments as ecash
you can pay ln invoices from ecash balance

your note can get zapped to your minibits address if it is in your ln address of your nostr profile and it automatically arrives in minibits wallet as ecash

you can zap in nostr client and approve automtically in minibits, two clicks 

Amethyst also has slick redemtion of ecash tokens that are dm'd via nostr contacts as you can send ecash to any npub via minibits
 

 Lots of good information here. Thanks. 

 The most important question is always ultimately "who controls the keys to the lightning channel that holds the sats backing the ecash tokens?" I know you know this, but just inserting this here for others who may not, and maybe that's part of what you were getting at with your initial post in this thread. Cashu is useful but it is 100% ruggable by whoever runs the node that backs the mint. People have to understand this. 

 100%. I'm starting to view it as a privacy layer for temporary sat storage. I don't know if I'd feel comfortable using it for large zaps either. As @kidwarp mentioned in this thread somewhere, you get in and you get out. Which, if you're doing that, telling people to constantly move their sats from nuts to sats, then it becomes extra steps that need to be done and not a good user experience for noobs. We're just replacing one custodian with another on a temporary basis in the same of privacy.
