Paste a private key to automatically sign the P2PK proofs. Keys are processed locally in your browser only. Your private key is NEVER sent to our server or the mint. For maximum security, however, we recommend using a signString() compatible Nostr extension like Alby, or AKA Profiles. If you have a NIP-60 Cashu Wallet, like NutSack, you may be able to unlock your token using a regular NIP-07 signer. Your name will not appear above in this case.

About this tool
Cashu Witness lets you unlock a locked Cashu token by signing it with your private key (Nostr NSEC or P2PK). This tool supports multi-signature (multisig) tokens, and will show you whose signature(s) are required to unlock. You can send a partially signed token to other signatories to sign to complete a multisig unlock. Once all signatories have signed, you can swap the token with the mint for an unlocked one you can spend anywhere.
You can create locked tokens in many Cashu wallets, and advanced multisig tokens using Cashu NutLock.
