Very cool.

I am doing something similar with @openbalance.app. If you send to a lightning address, it will DM Cashu tokens of corresponding amount to the npub holder. The safebox component I am building will check for DMs and redeem the tokens into its own balance. nostr:note1sht02zmr7ep4c29dpkeajzjswyy9tmw02n0kla4x843y9e0vpasqyq7k4a
