New · ZEROTRACE Shield
Shield your ETH, unshield it
Put ETH in from one wallet, take it out to another with a private note. Nobody can link the two, and the new wallet needs no ETH for gas.

Fixed amounts make every deposit look the same.

Proofs are made on your device. The relayer only sees a zero-knowledge proof, never your note.
How Shield works
- 1
Shield
Pick 0.5, 1, 2 or 5 ETH and confirm in your wallet. The deposit is public, like walking into a crowded room.
- 2
Keep your note
Your browser creates a private note, one line of text. It is the only key to the ETH. Copy it or download it.
- 3
Wait a little
The more deposits arrive after yours, the harder it is to tell which one is yours. Patience is privacy.
- 4
Unshield anywhere
Paste the note on any device, pick a fresh address and withdraw. A zero-knowledge proof shows you own one of the deposits without saying which.
What makes it different
- Instant. Every deposit is approved automatically in seconds. No waiting hours for a review.
- Nobody can exclude you. The approved set is posted by a contract that can only post "every deposit, in order". Not even ZEROTRACE can leave a deposit out.
- Nobody can change the rules. Ownership was renounced at launch: no upgrades, no pause, no new fees, ever.
- Battle-tested cryptography. Built on the audited Privacy Pools contracts, using the same verifiers and trusted-setup ceremony as the 0xbow pools on mainnet.
- No gas on the new wallet. The ZEROTRACE relayer sends the withdrawal and takes a small fee from it (about 0.25% plus gas). Shielding itself is free.
Honest limits
- Deposits and withdrawals are public. What stays private is which deposit paid which withdrawal.
- Privacy grows with the number of deposits. Withdrawing 1 ETH a minute after depositing 1 ETH is easy to pair. Wait, and split amounts.
- Lose the note and the ETH is gone. Nobody, including us, can recover it. You can always take your own deposit back publicly with the deposit wallet.
- The pool contracts are audited code, but this deployment and the approval contract are new. Start with small amounts.
