Tornado Cash

Tornado Cash is a non-custodial privacy protocol on Ethereum: users deposit fixed amounts of ETH or tokens into immutable pool contracts and later withdraw to a different address with a zero-knowledge proof, breaking the on-chain link. The US sanctions imposed in 2022 were lifted in March 2025; the interface is published on IPFS under tornadocash.eth.
