Connect your wallet

Use the wallet you already have. Next you'll sign one message — it derives your shielded keys right here in this tab. Nothing is sent to our server.

Preview every screen first — nothing to sign, nothing to install.

Viewing key

A viewing key can see but never spend. It stays in this tab.

Shield

Moves funds from your wallet into your shielded balance. This step is public (it shows your wallet depositing), which is why sends and unshields go through the relayer.

Amount

Asset

Also publish my shielded key under my 0x address, so people can pay me by 0x. Leave off to stay unlinked — share your nvs1… address instead.

Send privately

Paste a shielded address (nvs1…), a nullvisor: payment link, or a 0x address that registered its key.

Encrypted memo 0 / 512 bytes

Receive

Your shielded address. It is not tied to your 0x wallet on-chain — share it freely.

Viewing keys

Zcash-style selective disclosure. Give an accountant or auditor read access without giving them spend power.

Incoming viewing key — sees what you received + memos

Full viewing key — also sees what you spent

Anyone with these keys can read your shielded history forever. They cannot move funds.

Unshield

Pays out to any public 0x address. Recipient and amount become visible; who sent it does not.

Destination 0x address

This is the wallet you're connected with. Unshielding back to the address that deposited links the two ends together.

Amount

Asset

Release in the next wave (recommended) — leaves together with other unshields, in shuffled order.

ⓩ Exit to Zcash

Unshield straight into a Zcash wallet — Zodl/Zashi unified (u1…), Sapling (zs1…) or transparent. The relayer posts your proof, a one-purpose forwarder can only pay the swap solver, and ZEC lands on Zcash. No 0x address of yours touches it.

Zcash address

Amount

From

Refund address on Robinhood Chain (if the swap can't fill)

Leave in the next unshield wave.

ⓩ Enter from Zcash

Pay from any Zcash wallet and receive a private USDG note here. Only your browser can claim it: a one-off claim key derived from your account signs the shield, so nobody who sees the deposit can redirect it.

Your notes

Decrypted locally from the public note log. Memos are visible only to you.

Nothing yet.

Turnstile

Borrowed from Zcash: individual notes are private, but what enters and leaves the pool is public. If shielded − unshielded ever differs from the contract balance, something is wrong — anyone can check.
