BindowsCash is a decentralized, non-custodial mixer that allows you to **anonymize your crypto transactions**. It uses a system of commitments and double-hashing methods 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. BindowsCash 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? BindowsCash currently supports **BNB** and **USDT** on the **Binance Smart Chain** (BSC).\ **$BINDOWS** token will follow next.\ We plan to allow any BEP20 token to integrate our ecosystem (as a paid service, paid in $BINDOWS). *** #### 🧾 How much can I deposit? There are currently **six fixed deposit amounts** for BNB on BSC: * 0.001 BNB * 0.01 BNB * 0.1 BNB * 1 BNB * 10 BNB * 100 BNB And four fixed deposit amounts for USDT on BSC: * 10 USDC * 100 USDC * 1000 USDC * 10k USDC 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, and we cannot do anything on our side. *** #### 🧾 Is there a fee? * BindowsCash takes **1% fee on any deposit** to support sustainability (taken between the deposit and withdrawal) and to fund the staking pool. * The fee is **hardcoded** in the smart contract, as well as the address receiving the fees.\ They 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 (= active deposits), the harder it is to trace your withdrawal.\ Just make sure that some deposits are made after yours, even if some time passed, if no deposit was made after yours, it's better to wait for another deposit being stacked on top of yours. *** #### 🎭 Can I withdraw to any address? Yes! You can withdraw to: * A **new wallet** that you connect to the dApp. It can be a fresh one, or a wallet that you previously used. * The best practice is to generate a new address, and withdraw with the gasless option, so what you don't have to fund the wallet from a CEX the first time. 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. BindowsCash 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. To avoid this, always keep your note safe and hidden and never share it, no one should ask you to provide it. *** #### 🧪 Is BindowsCash 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. Our project is still experimental and some bugs may appear, even if a lot of tests have been performed on testnet and mainnet prior to launch. Obviously, if you have any question, issue or feedback to submit, you are welcome to join or Telegram group ([t.me/bindowscash](https://t.me/gotham_cash)), where the administrator or community members will help you. *** #### 🦇 Is BindowsCash affiliated with TornadoCash? No. BindowsCash is a **community project**, inspired by the ideals of financial freedom and privacy. It is **not** affiliated with TornadoCash or any other entity. *** #### ⚠️ Is this legal in my country? **Laws vary** depending on your jurisdiction. BindowsCash is a decentralized tool and does not promote illegal activities. You are responsible for understanding and complying with local laws. BindowsCash 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.
