It's the same real world use as using Wallet of Satoshi, but with significantly better privacy, distributes custodial risk, and helps decentralize the lightning network more by lessening the need for large custodial wallets.
Proving you have a claim to sats held by a mint and can tell it to send them somewhere.
I think mint+send and receive+burn (send to lightning)/receive+sweep (to preferred mint) would be helpful functions in Cashu wallets.
There is receive+burn here. But it should be front & center in the wallet, especially for merchants.
Does Alby work as a bridge between LnBits wallets and Amethyst via wallet connect? Or does that only work with a custodial Alby wallet?
Also, you can add numerous mints on that web wallet (just like) Cashu. It holds the ecash you have on each mint.
All mint tokens stay on the mint. They never move off. They are only created and burned. Only Bitcoin over lightning moves in/out of mints.
My #[0] is starting to get slow and unreliable again. Lots of force closed channels and zapping to my lightning address is unreliable. Is there anything I can do besides upgrade my VPS or start fresh?
I haven't explored other ways to run a mint, but I'm just running LNbits and connected it to my lightning node. There is an extension in LNbits to run a Cashu mint.
Do you need to run a mint? I don't know. It's early.
Probably not. Cashu is lightning-only so "mixing over lightning" is a bit more involved than just conjoining to cold storage on Sparrow.
But I think it adds some interesting privacy benefits to lightning and may make coinjoining less necessary if most of your Bitcoin income is over lightning.
Cashu adds plausible deniability to your lightning node's outgoing payments. You're no longer the only one making transactions out of it and you can't know who did.

So in LnBits I was able to create a Cashu ecash mint. Then as a user I sent myself Bitcoin over lightning and the mint credited me some ecash.
Then I was able to go into my LNbits wallet and drain the sats from it. The Cashu wallet still shows that it held the ecash and I could send it around. But when I tried to send sats out of the mint, burning the ecash it wouldn't send because there was no actual Bitcoin held by the mint. It was really easy to rugpull myself.
As a merchant, I see how someone could mint some ecash, drain the wallet, then try to buy something from me. I wouldn't know the ecash was worthless until I tried to claim the sats later. It's like writing a bad check.
So yeah, not great for stores to accept Cashu payments unless the ecash is on a mint they trust. The wallet does ask you if you trust a mint when receiving ecash so you do have a small "due diligence" step before accepting payment.
I would like to see a receiving Cashu wallet that automatically sweeps ecash onto a chosen mint or just to a lightning address immediately upon receipt to mitigate this attack.
I don't know but it's pretty interesting to mess with. I think it will be great for family wallets. There's a lot of trust involved.
Testing Cashu. Someone can take these 10 sats, right?

What if they buy ordinals because their mouses only have left buttons?
I've never played either with Bitcoiners. Normally just beers and conversation is plenty to make the night fly by.
