Pick your index

SPY or QQQ. The one you pick is the pair token of your coin's curve. Every trade is priced in it.

Every buy fills the vault

Buyers pay the curve in the index fund. Sells take it back out. The contract holds it, not us.

Graduation

When the curve reaches its threshold, trading moves to a Uniswap pool.

Founder fee

You keep a 2% creator fee on curve trades. Launching is paid in ZEC: one address, one amount.

Why ZIndex exists

Most new coins are backed by nothing but the next buyer. The quote asset is whatever was cheapest to pair with.

ZIndex changes the quote asset. Your coin's curve is denominated in a tokenized index fund, SPY or QQQ. You pay for the launch in Zcash, with no wallet to connect. Buys put the index fund in. Sells take it out. The contract holds it the whole time.

It is still a new coin, and a raise is never a promise. But what sits behind it is the index, and anyone can read the balance on chain.

How it works

Four steps. You pay in Zcash and the launch runs by itself. Trading afterwards happens from each trader's own wallet.

01

Pick SPY or QQQ

Name your coin and choose the index fund. It becomes the pair token of the curve, and it cannot be changed afterwards.

02

Send ZEC

You are shown one Zcash address and one amount. No wallet to connect. The coin launches by itself, usually within about 15 minutes of the payment confirming. If the payment is short or never arrives, the ZEC is returned to the refund address you gave.

03

Buys fill the vault

Buyers pay the curve in the index fund and get your coin. Sells hand the coin back and take index fund tokens out.

04

Graduate

At the threshold the curve closes and trading moves to a Uniswap pool. Until then you earn a 2% creator fee on every curve trade.

FAQ

  • ZIndex is a launchpad you pay for in Zcash. It launches coins on PONS v2 bonding curves where the quote asset is a tokenized index fund, SPY or QQQ.

    Founders name the coin, choose the index fund and send ZEC to the address shown; there is no wallet to connect, and the coin launches by itself. Buyers and sellers sign their own trades from their own wallets. ZIndex keeps a list of what launched. It never holds a trader's funds.

  • A bonding curve has two sides: the coin and the asset it is priced in. On ZIndex that asset is a tokenized index fund. When someone buys, they pay the curve in SPY or QQQ and those tokens stay in the curve contract. When someone sells, the curve pays them back out of that same balance.

    So the coin is a claim on the index fund tokens the curve holds. That is what "backed" means here. It does not mean the coin is worth a fixed amount, and it does not mean anyone guarantees the price.

  • Two, for now: tokenized SPY (S&P 500) and tokenized QQQ (Nasdaq-100). You pick one per coin. The choice is fixed at launch.

  • To buy, you approve the index fund token and send a buy to the curve from your wallet. The curve takes your SPY or QQQ and sends you the coin at the current curve price. The price moves up the curve as supply is sold.

    To sell, you send the coin back. The curve pays you in the index fund token at the current curve price, which moves back down. A 2% creator fee comes off curve trades and goes to the founder's wallet. Each trade is a transaction you sign; gas is paid in ETH on Robinhood Chain.

  • Every curve has a threshold. When enough of the supply has been bought to reach it, the curve closes and its liquidity moves to a Uniswap pool. From then on the coin trades on the pool rather than the curve.

  • You pay in Zcash. The launch page shows one Zcash address and one amount before you send anything; there is no wallet to connect and no subscription. The coin usually launches within about 15 minutes of the payment confirming. If the payment is short or never arrives, the ZEC is returned to the refund address you gave. After launch, you receive a 2% creator fee on every curve trade in your coin.

  • No. A coin on ZIndex is a new token with a bonding curve behind it. The curve holds index fund tokens, but the coin's price comes from the curve and from what other people do, and the index funds themselves move with the market. Nothing is insured, and a raise is not a promise of anything.

    The contracts are public on Robinhood Chain. Read them, read the balance, and only trade what you can afford to lose.

  • The curve contract does. Not ZIndex, not the founder. The SPY or QQQ paid in by buyers sits in the PONS v2 curve for that coin until it is paid out on a sell or moved to the pool at graduation. Anyone can check the balance on chain at any time.
