Robinhood Chain · zero-knowledge · zcash inside

the chain remembers everything. you don't have to show it.

Every swap, every payment, every balance sits in a ledger any stranger can read — indexed, searchable, permanent. nullvisor gives your funds somewhere to disappear: provable to the contract, invisible to everyone else, and one step away from Zcash.

00 · the film

A short film about being watched.

01 · read by strangers

What they see. What you see.

The same private payment, from both sides of the visor. The explorer gets a relayer and a proof. You keep the rest.

No witnesses.

shield

Sign once to unlock your shielded account, then deposit ETH or USDG. It becomes an encrypted note only your keys can open.

send

Pay any nvs1… address with an encrypted memo. A relayer posts the proof — your address never touches it.

unshield

Leave in waves: withdrawals gather and go out together, shuffled, so timing gives nothing away.

03 · the exit
ZCASH
robinhood chainzero-knowledgezcash shielded
exit

Leave straight into Zodl.

Unshield to a unified u1… address. A one-purpose forwarder can only pay the swap solver; real shielded ZEC lands on Zcash in minutes.

enter

Arrive from any Zcash wallet.

Pay a QR in ZEC and it arrives here as a private dollar note. A one-off claim key signs the shield, so nobody who sees it can redirect it.

keys

Zcash-grade viewing keys.

Spend key → nullifier key → address. Hand an auditor a viewing key that sees everything and spends nothing.

memos

512 bytes, sealed.

Every note carries a fixed-size encrypted memo — readable by one person, invisible to everyone else.

04 · trust nothing

Built so you don't have to trust us.

Privacy that depends on an operator behaving is a promise. These are properties of the code.

Keys stay in your tab.

Derived from a wallet signature, held in memory only. The server never sees them and cannot read your balance.

No upgrade switch.

The pool is not a proxy. Nobody can swap its logic; only a valid proof moves pooled funds.

Exits can't be frozen.

The guardian can only cap new deposits. Unshielding always works — even if this site disappears.

Turnstile in the open.

Notes are private, totals are not. In minus out equals the contract balance, per asset, for anyone to check.

Disappear.

Privacy isn't hiding. It's deciding who gets to look.

Read this first. nullvisor is new and has not been externally audited. Deposits are capped per transaction and in total while it matures. The circuit uses the public Perpetual Powers of Tau (phase 1) with a single-party phase 2. Deposits are public on-chain; privacy grows with the number of people using the pool. The Zcash leg relies on third-party NEAR Intents solvers. Not financial advice.
