FAQ
🔐 What is GothamCash?
GothamCash is a decentralized, non-custodial mixer that allows you to anonymize your crypto transactions. It uses a system of commitments and zero-knowledge principles to unlink your deposit from your withdrawal.
💸 Why would I use a mixer?
Every transaction on the blockchain is public and traceable — anyone can view your balance or who you interact with. GothamCash helps protect your financial privacy by breaking the on-chain link between sender and recipient. For example, you can receive a donation and later withdraw it to a new, unlinked wallet.
🪙 What currencies and chains are supported?
GothamCash currently supports BNB on the Binance Smart Chain (BSC). We plan to support Ethereum (mainnet) and possibly additional chains like Solana or Layer 2 networks in upcoming versions.
🧾 How much can I deposit?
There are currently three fixed deposit amounts:
0.1 BNB
1 BNB
10 BNB
Each pool operates independently.
You can only deposit and withdraw the exact amount of each pool. Partial withdrawals are not supported.
🧠 What is a "commitment" and a "note"?
A commitment is a cryptographic hash of two secrets (called nullifier and secret), proving ownership of a deposit — without revealing it. A note is like a receipt containing those secrets, allowing you to later withdraw the funds.
Keep your note secure and private — if someone else obtains it, they can withdraw your funds.
🧾 Is there a fee?
No fees during the initial launch phase (first month).
After that, a 1% deposit fee and a 1% withdrawal fee will be enabled to support sustainability.
Note that those 1% fees are hardcoded, and cannot be modified.
🕒 How long should I wait before withdrawing?
There’s no enforced delay. However, for optimal privacy, it’s best to wait a few hours or days — until more deposits have occurred.
The larger the anonymity set, the harder it is to trace your withdrawal. Just make sure your deposit does not sleep for more than 1 year to avoid expiration.
🎭 Can I withdraw to any address?
Yes! You can withdraw to:
A new wallet connected to the dApp.
Or, specify a custom beneficiary address (without connecting it).
Never withdraw to the same address you used to deposit — this defeats the purpose of mixing.
🧾 What if I lose my note?
⚠️ We cannot recover lost notes — and no one else can. GothamCash is non-custodial and doesn’t store any user data. The note is your only proof of deposit. If it’s lost, the funds are unrecoverable.
🧪 Is GothamCash audited?
The initial version is based on well-understood principles and a minimal, auditable codebase. A full third-party audit is planned for the next release cycle. In the meanwhile, the source code is public and open-source, published on GitHub.
🦇 Is GothamCash affiliated with Batman or TornadoCash?
No. GothamCash is a community project, inspired by the ideals of financial freedom and privacy. It is not affiliated with DC Comics, TornadoCash, or any other entity.
⚠️ Is this legal in my country?
Laws vary depending on your jurisdiction. GothamCash is a decentralized tool and does not promote illegal activities. You are responsible for understanding and complying with local laws.
GothamCash is a permissionless smart contract — a neutral tool that anyone can use. Like any financial tool, its legality depends on your local laws and how you use it.
