Cashu NutZapMe

Cashu NutZapMe lets you create a NIP-60 compliant Cashu Wallet and advertizes the public key so you can receive NIP-61 NutZaps. It also makes a backup of the wallet so you never lose the private key.

Choose the NUT-11 compliant mints you are comfortable using.
These are the Nostr relays where your ecash will be stored (max recommended 2-4). Use the button to fetch your relays if using a NIP-07 extension.

About this tool

This tool creates the following Nostr events:

NIP-60 Wallet (kind:17375) – this creates a Cashu wallet stored in Nostr, which means it is accessible across applications. It contains the mints you use and a random private key (separate to your Nostr nsec).

NIP-60 Wallet Backup (kind:375) – this is a backup of your NIP-60 wallet, and is exactly the same as the kind:17375 event, with the addition of a tag containing your public key to allow easy retrieval if needed.

NIP-61 NutZap informational event (kind:10019) – this tag tells other people how to send ecash to you. It contains the mints you use, the relays you’ll read NutZaps from, and the pubkey they should P2PK lock your ecash to. The pubkey corresponds to the private key in your kind:17375 wallet.

Once created, your NIP-60 Wallet private key and NIP-61 NutZap public key can be used to NutLock tokens too.
