What is Cyclone?

Cyclone Protocol is a non-custodial privacy mixer that uses zkSNARKs adapted from the Tornado Cash codebase to anonymize deposits and withdrawals across Ethereum, Polygon, BNB Chain, and IoTeX. Users deposit ETH, USDT, BTCB, and other supported assets into anonymity pools and later withdraw to fresh addresses. CYC token holders govern pool parameters and earn anonymity mining rewards proportional to how long deposits stay in the pool.
