Zero-knowledge payments on Robinhood Chain

Ask AI anything.Leave no nameat the gate.

Private Park lets you pay for AI with a zero-knowledge proof on Robinhood Chain. No account, no email, no name on the receipt.

Open dashboard Walk the trail

Right now, every prompt wears your name.

Your API key points to an account. The account points to a card. Every question you ask gets filed under you, and the file only grows.

Step 1 of 3

Buy one ticket.

Deposit ETH into the park vault on Robinhood Chain. One transaction. Tickets come in fixed sizes, so every visitor looks the same at the gate.

Unused balance stays yours. Withdraw it any time, to any address you choose.

Step 2 of 3

Change skin on every request.

Your browser proves you hold a paid ticket without showing which one. Each request gets a fresh key that lives for seconds, then it is gone.

Nothing links one question to the next. Parker is showing you how it looks.

Step 3 of 3

Disappear into the crowd.

Your prompt goes straight from your device to the model. The model answers it and has no idea who paid.

A hundred questions could be a hundred people, or just you. Nobody can tell.

Park rules.

Six rules come with every ticket.

  1. No name tagsNo email, no phone number, no account. A wallet is all you need.
  2. No name on the receiptA zero-knowledge proof pays for you. It never says which ticket is yours.
  3. New skin every requestEach request gets a fresh key, so one question does not lead to the next.
  4. Your prompt skips our serverIt travels straight from your device to the model.
  5. Pay only for what you useMetered by the request. The rest of your balance waits for you.
  6. Your exit is always openWithdraw to any address. The vault pays out even without our server.

$PrivaP burns when the park is busy.

Usage you cannot see. Burn you can verify.

Every settled session pays a 5% service fee. Half of that fee buys $PrivaP from the open pool and sends it to the burn address. More usage means more burn, and every burn is a public transaction.

Burns run in batches, so no single session can be traced through one. Money in and out of the vault stays on the public record. Only what you do inside is private.

Questions at the gate.

What is Private Park?

A way to pay for AI without an account. You deposit ETH once, then every request is paid with a zero-knowledge proof instead of your identity.

Do I need to sign up?

No. There is no sign up, no email and no password. Bring a wallet and buy a ticket.

What can I do inside?

Chat with AI from the dashboard, paid from your ticket balance. Every request goes out under a fresh key.

How does $PrivaP fit in?

Every settled session pays a 5% service fee. Half of it buys $PrivaP from the open pool and burns it. The busier the park, the bigger the burn.

Can I take my ETH back?

Yes. Withdraw your unused balance at any time, to any address. The vault also has an exit that works without our server.

Where is the contract address?

It will be published on this page at launch. This page is the only official source.

Where are the technical details?

In the docs. They cover the protocol, the trust model, limits and risks.
