An onchain prediction market on Sui. Each race opens at the live price and sets two barriers, +0.25% and -0.25%. Call the one it touches first, trade until the touch, and every winning token pays 1 USDC.

Strike. Spread. Race. Settle.

Starting line

Strike

A race opens at the live Pyth price. That number, recorded on chain, is its starting line.

±0.25% barriers

Spread

Two barriers go up the same distance away: 0.25% above and 0.25% below for Bitcoin. UP takes the upper one, DOWN the lower one.

±0.25% barriers, following the demo race
No lockout

Race

There is no clock. Buy, sell or switch sides on DeepBook's order book at any moment until a barrier is touched.

First touch wins

Settle

The first Pyth price at or past a barrier settles the race, and anyone can submit it. Winning tokens pay 1 USDC each, and the next race opens seconds later.

Try a race. Play money, real rules.

Demo BTC race #1 Time 0:00 From strike +0.000%
UP 50% Fair odds 50% DOWN

At the strike, UP and DOWN are both worth about 50¢.

A demo with play money on a simulated price, sped up and quoted at its fair odds. A real race trades on DeepBook order books, where traders set the prices and fees apply, and it can run for minutes.

One dollar. Two tokens. One winner.

  1. 01 Deposit

    USDC in, CASH out

    Deposits turn USDC into CASH one for one, inside your own Oqen account. Withdraw, and it turns back into USDC.

  2. 02 Mint

    One CASH, one of each

    After the mint fee, each CASH mints one UP and one DOWN for the current race and is locked in that race's own vault. Every pair is backed by a full dollar.

  3. 03 Trade

    Price is probability

    UP and DOWN each trade against CASH on their own DeepBook order book. UP at 62¢ means the market sees a 62% chance.

  4. 04 Settle

    The winner takes the dollar

    The first touch decides it. Each winning token pays 1 CASH from the race's vault, and each losing token pays nothing.

Bitcoin first. Four more in orbit.

Fully onchain on Sui. Deposit USDC, trade UP and DOWN on DeepBook's central limit order book, and withdraw USDC whenever you like. No sign up and no token approvals: your wallet opens an Oqen account, and only your wallet can use it.

No DeepBook trading fees on Oqen's books. Oqen's own fee is charged only when sets are minted, and the contract caps it at 1.00%.

ON THE WAY

Two answers today.
More tomorrow.

Multi-outcome markets are coming on the same rails: the same DeepBook order books, the same Pyth prices, the same rule that one winning token pays one dollar. Just more than two ways to be right.

Trade. Hold. Post. Oqen keeps an open eye.

2 outcomes

Straight answers.

What exactly am I predicting?

Which barrier the price touches first. Each race opens at the live Pyth price, the strike, and sets two barriers the same distance above and below it: 0.25% either way for Bitcoin. UP wins if the upper barrier is touched first, DOWN if the lower one is. There is no timer.

How much can I win or lose?

Every winning token pays 1 USDC and every losing token pays nothing. Buy UP at 40¢ and each token returns $1.00 if UP wins, two and a half times what you paid, or nothing if DOWN wins. Until the touch you can also sell at the current price.

Who sets the prices?

Traders. UP and DOWN trade against CASH on DeepBook, the central limit order book on Sui, so every price is a real bid from another Oqen account, not a formula. One UP and one DOWN are always minted together for one dollar, so their prices add up to about $1.

What if the price never touches a barrier?

The race keeps going: nothing expires. If the price feed ever stops, the race can be voided, and every UP and DOWN token then pays 50¢, so a full pair gets its dollar back. A race that the latest price would settle can never be voided.

Who decides the result?

The price. The first Pyth price at or past a barrier, published after the race opened, settles it, and anyone can submit that price. The Oqen keeper does it within moments, but it needs no permission and neither does anyone else.

Where is my money while I trade?

In your own Oqen account, an object on Sui that only your wallet can use, holding a DeepBook balance manager. USDC becomes CASH one for one inside it, and CASH becomes USDC again when you withdraw. UP, DOWN and CASH never leave Oqen accounts, which keeps every race separate and fully backed.

What does it cost?

DeepBook charges no trading fees on the Oqen order books. Oqen charges a fee only when sets are minted, capped at 1.00% by the contract, and every transaction pays the usual Sui network fee.

Is it safe?

No smart contract is free of risk. The Oqen contracts run more than 200 tests, including end-to-end runs against the code of DeepBook, Pyth and Wormhole themselves, and are checked by mutation testing. External audit reports will be linked on this site once they are published. Read the risk disclosure before you trade.
