How Tornado Cash Works
Deposit
A user generates a random key (a secret note) and deposits Ether or an ERC20, along with submitting a hash of the secret note to the Tornado Cash smart contract.
Wait
After depositing, users should wait some amount of time before withdrawing to improve their privacy.
Withdraw
A user submits proof of having the valid key to one of the deposited secret notes, and the contract transfers the funds to a specified recipient.

Start TutorialHow Tornado Cash Achieves Privacy
Tornado Cash improves transaction privacy by reducing public on-chain linkage between source and destination addresses. It uses a smart contract that accepts ETH deposits that can be withdrawn by a different address. To preserve privacy, a relayer can be used to withdraw to an address with no ETH balance. Users should still manage wallet, timing, network, and compliance risks carefully.
Status of Tornado Cash Decentralization
The Tornado Cash protocol is fully decentralized and owned by the community: the initial developers have no control over it and are not running any servers.
Tornado Cash smart contracts, circuits, and toolchain are fully open-sourced.
Tornado Cash smart contracts are unstoppable: there are no admins and no upgradeability. Nobody, including the initial developers, can change or shut it down.
The user interface is hosted by the community on IPFS. It is accessible as long as at least one user in the world is hosting it.
Tornado Cash governance and mining smart contracts are deployed by the community in a decentralized way; there is no single deployer.
Protocol parameters and token distribution are controlled by the community via governance.

Yes. The protocol is non-custodial and immutable. Smart contracts have been heavily audited by experts like ABDK and Pessimistic. Audit reports:
Relayers enable gas-free withdrawals to addresses with no ETH balance, preserving anonymity. The relayer pays the gas fee and takes a small compensation from the deposit. Relayers cannot alter transaction data or steal funds.
Making your ETH transactions private is a straightforward process. We've prepared a detailed, step-by-step guide with screenshots to walk you through it safely.
Yes, the protocol supports various ERC-20 tokens, including USDT, USDC, and BNB. The process is very similar to handling ETH but requires an additional token approval step. To ensure you follow all the steps correctly, please refer to our dedicated guides.
