A proof-of-concept to transfer bitcoin sats as ecash via sound using the Cashu protocol.

Ecash can be sent digitally as text data, visually via a QR code reader, physically as a piece of paper with text or a QR printed on it. How about audibly? Can ecash be sent via sound?

There are 21 sats as a cashu/ecash token at https://crrdlx.on.fleek.co/ecashsound/ to the first person to get them. Will this be the "world's first" ecash sent via sound? I don't know. Still, is has a nice ring to it and maybe you can be a small part of ecash/bitcoin history. 😀
