Although ecash could make sense for use cases like stacker news. Stackers could zap each other ecash non custodially
You can use ecash with SN already: #752528

Ah I meant using ecash instead of cowboy credits to avoid custody legal issues

If the receiver isn't online, who custodies the ecash when you send it to them?
The best you can do is bind the notes to a receiver's keypair, but that requires the receiver to trust the sender's mint until they come online (a delayed, possibly fraudulent promise of settlement) ... unless you send to the receiver via lightning which is #752528.

Yep that's what I was thinking. Sender encrypts bearer ecash with receivers pub key. Stacker news stores that encrypted blob. No custody issues for you as you can't get the money.
Yep, the tradeoff is you have to trust the sender/zapper not to double spend that ecash. Think that's ok in the zapping situation.

It's not just that. The receiver also has to trust the mint to let them redeem real money and without KYC.
For Stacker, it's also important for us to be able to verify the payment is real and what the sat value is.
