Privacy
🕵️ Privacy
Privacy is not a crime — it's a right. GothamCash is designed to restore your transactional privacy on public blockchains, without requiring accounts, trust, or surveillance.
🔗 Breaking the On-Chain Link
Public blockchains (like BNB Chain or Ethereum) expose every transaction, letting anyone trace funds between wallets.
GothamCash uses commitments, nullifiers, and off-chain notes to break this traceability:
Your deposit and withdrawal are fully unlinked.
No addresses are stored during deposit.
Withdrawals can be sent to any address — even one with no prior activity.
The note string is never submitted to the blockchain.
Observers cannot correlate your input and output.
🔐 Privacy-Preserving Authorization
Although GothamCash does not use zk-SNARKs, it provides a simplified zero-knowledge-like model through:
Off-chain note generation (
nullifier + secret)Withdrawal authorization via signed message, proving:
You own the note
You consent to a specific recipient
No other party can reuse your note
This method allows any recipient address to receive funds without revealing who originally deposited them. The signature is verified on-chain, but does not leak your address.
🧑💻 No Accounts. No Logins. No Surveillance.
GothamCash operates without:
Centralized servers
User registrations or accounts
Emails, logins, or KYC
Blockchain analytics tools or IP tracking
All interactions occur directly between your wallet and the smart contract, with full self-custody and anonymity.
🛡️ Withdraw to Cold or New Wallets
For maximum unlinkability, you can withdraw to a wallet that:
Has never interacted with GothamCash
Has no prior blockchain activity
Ideal for:
Cold storage / hardware wallets
Freshly generated wallets
Sensitive addresses
This completely breaks any observable link between deposit and withdrawal.

💡 Tips for Maximum Privacy
To stay fully anonymous, we recommend:
🆕 Use a new wallet to make your deposit.
⏳ Wait before withdrawing — several hours or days helps mix with other users.
🧼 Withdraw to a clean recipient address / fresh wallet with no previous on-chain activity.
🔐 Store your note offline (e.g. encrypted USB, password manager, or printed + locked).
🌐 Use a VPN and private browsing tools.
📱 Always interact from a secure device (no malware, no screen recorders).
Remember: privacy depends as much on the tool as on how you use it.
