Greeting Cards give bitcoin using the Cashu protocol.
I wrote about creating greeting cards designed to pay people in bitcoin with Cashu. I plan on selling these, but I like the ethos of open source so I decided to open source my cards. I will still sell them, but I also want people to create cards themselves. That will get more sats in the hands of more nieces and nephews. That's the ultimate goal really.

Cashu is in the very early days. These cards are designed for small amounts of bitcoin to be given away as gifts. It is non-custodial bitcoin that can be redeemed for bitcoin onto your own wallet over the lightning network much like a check from a bank can be redeemed or cash. Please do not use this for serious money as it is in the experimental stage of development. It is not suitable for your life's savings. Never put more money into cashu than you are prepared to lose.
