NutZaps got overhauled in Nostr back in February, and I couldn't find a client that works according to the revised spec. So I built NutZapMe.
It lets you create a NIP-60 compliant Cashu Wallet, a backup wallet, and a NIP-61 NutZap informational event to tell people how to send you ecash.
Once setup, you can also use your NIP-60 wallet to NutLock tokens, and unlock them using any regular Nostr signer extension.
I built it because I wanted to add NIP-60 support to Cashu Witness, and needed to set up my own NutZap wallet for testing.
