Save your note securely

After making a deposit, you will receive a unique note — this is the only proof that you are the owner of the deposited funds. You’ll need this note later to withdraw anonymously.

The note looks like this:

gothamcash-1:0x<nullifier>:0x<secret>

This note contains two essential secrets:

  • The nullifier, which prevents double spending

  • The secret, which protects your privacy and ensures uniqueness

🛑 If you lose this note, you lose access to your funds. There is no way to recover it.


✅ Tips for storing your note safely:

  • Store it in a secure password manager (e.g. 1Password, Bitwarden, KeePass)

  • Back it up offline: write it down on paper and store it in a safe location

  • Do not take a screenshot or store it in plain text on your computer or phone

  • Avoid cloud storage unless encrypted (e.g. use a GPG-encrypted file or vault)

  • Do not share the note with anyone — anyone who holds it can withdraw your funds

  • Never paste it into a public chat or online form, even for support or administrators


Optional: Encrypt your note

For added protection, you can encrypt your note with a passphrase using tools like:


Treat your note like a private key. It’s your anonymous ticket to reclaim your funds — once lost, the funds are locked forever.
