Hold ZEXX.
Leave no trail.

ZEXX is a privacy token on Robinhood Chain. Payments land on one-time stealth addresses, and every trade pays the vault holders.

what anyone can traceyour address, public

A normal token. Every balance and payment is a public record, and one labelled address ties the rest to you.

Vault backing

live after launch

Every share of the vault claims part of this ZEXX. Payments move shares to one-time addresses; only their owners can find them.

Follow one payment.

Send 1,500 ZEXX to a friend and see what each part of the system learns along the way.

  1. 01Your wallet

    Sign once

    Your wallet signs one message and your stealth keys are derived from it. Nothing new to write down: same wallet, same keys, on any device.

    First time only: one small transaction registers your public stealth key, so others can pay you privately.

  2. 02Your browser

    A fresh address for your friend

    The app mixes your friend's public stealth key with a random secret and computes a one-time address only they can control. It has never appeared on-chain before.

  3. 03Relayer

    Signed, then relayed

    Stealth addresses never need ETH. You sign the transfer and anyone can relay it, taking a small fee in ZEXX from your balance. The amount you send stays public.

    The vault moves the share

    The vault checks the signature, moves the share to the new address and publishes an announcement so the recipient can find it.

    Only your friend can find it

    Their viewing key scans the announcements and recognises the payment: 1,500 ZEXX, ready to spend or sell. Anyone can still verify the transaction.

Every trade pays the vault holders.

The creator fee on every ZEXX trade, wherever it happens, buys ZEXX for the vault. Every share of the vault grows with it. Yield depends on real trading and is not guaranteed.

  1. Every trade

    On the Pons curve, on Uniswap v4 or through any aggregator, each trade pays a creator fee.

  2. Harvester

    Collects the fee and buys ZEXX at the average price. Whoever calls it keeps a 0.5% tip.

  3. Vault

    Receives that ZEXX as a donation, without issuing new shares.

  4. Every share

    Each share of the vault is worth more ZEXX. Yours included.

  1. Buy it privately

    Pay ETH in the app and ZEXX lands straight in the vault. The purchase itself is visible; where you send it next is not linked to your friend's wallet.

    Open app

  2. Trade it anywhere

    ZEXX is an ordinary ERC-20: on its Pons curve, on Uniswap v4 once it graduates, and through aggregators.

  3. Shield what you hold

    ZEXX bought elsewhere sits in your wallet in public. Shield it in the app and it becomes a vault share, where it starts earning.

No keys but yours.

No freezes, one emergency key.

The vault has no pause and cannot be upgraded, and no one can move a share without its owner's signature. The developer wallet keeps an emergency key that can drain the vault's ZEXX, so holders trust the team with it. The contracts are unaudited, so start small.

  • Owner's signature only
  • No pause
  • Emergency key

Keys made on your device.

Your stealth keys are derived in your browser from one wallet signature. They never leave the page, and no server sees them.

paid in ZEXX, from your balance

Stealth addresses never need ETH.

The owner of a one-time address signs; anyone can relay the payment and take a small fee in ZEXX. Nothing has to be funded first, so nothing links back to your wallet.

Nothing to back up.

Your keys come from one wallet signature. Same wallet, same keys, on any device.

Public, and still verifiable.

Every payment can be checked by its transaction: which one-time address was paid and how much. The sender stays visible too.Verify a payment
