This has also been in my line of thoughts:
@trab
Thank you, these are the kind of use case I think we should be collecting. Lets brainstorm a bit about these use cases.
Use Case 1: Venmo/Cash App experience
I also was thinking about the IOU kind of situations. As long as the creditor is online, this should not be a problem. Meaning that mobile phone wallets are key for these kind of use cases. Also I would love it, if you could for example let your buddies pay you their share of drinking money in Grin - not by owning it, but by them b…
Alternatively you have this Grin Pi project by @mcm-mike ,
