The Critical Deposit Phase

Initiating a transaction with Tornado Cash starts with the deposit phase. After connecting a compatible Web3 wallet, you select an asset and amount to send to the protocol’s smart contract. Upon confirmation, your funds are locked in the pool, and you receive a unique secret note. This note is your sole key to accessing these funds later and must be guarded meticulously. The Tornado Cash guide 2025 emphasizes that losing this note will result in the permanent and irreversible loss of your deposited capital.
