Could cashu or fedimint also be used to issue stable coin tokens? I'm trying to think of a way to use this tech for festivals.

Ideally..

* festival goers buy cashu tokens (could just be SATs, but to get agreement from stallholders festival management, sat to dollar ratio would need to be locked for length of festival).

* NFC chips in wristbands could be used for purchasing food etc at stalls.

* mobile phone app used to check balance of NFC band, lock it, unlock it, set spend limits.

* tokens could be redeemed for bank deposits at end of festival.

They had this at last festival I went to (no phone app though).
