Onchain fixed-outcome trading
Binary options without trusting a broker.
Trade whether crypto finishes above or below your entry. Your stake, payout, entry and settlement are recorded onchain and verified with Pyth — not decided in a broker’s private database.
No wallet needed for the demo · the testnet uses valueless tUSDC, never real funds.
BTC / USD$64,111.29−0.25%BTC / USDFixed maximum loss
Your stake is the most you can lose. No leverage, no margin calls, nothing to liquidate.
Payout fixed before entry
You see the exact return before you commit. The payout is locked into the position when you open it.
Non-custodial
You connect your own wallet. Collateral sits in the contract — the operator cannot withdraw it.
Pyth-settled outcomes
A Pyth price update decides above or below — not an internal broker database.
Public settlement proof
Every position and its settlement is a transaction anyone can open on a block explorer.

INJInjectivePrices stream live from Pyth. Every pair trades all six expiry clocks — 15 seconds, 1, 5, 15 minutes, 1 and 4 hours. Payout shown is the current quote and is locked into your position when you open it.
How a trade works
Three steps to a position.
Choose market, expiry and amount
Pick UP or DOWN
You see the exact payout before you commit. It locks into the position.
Pyth settles it at expiry
Your wallet confirmation determines the next valid Pyth price used as your strike. The entry is recorded from the first valid price published after confirmation — so no one can pick a favourable historical price, and there is no entry timing to game.
While the position is open
Watch it move against the strike.
Above the strike the position is in the money; below, out. The outcome is fixed the moment the expiry price prints.
Where the result comes from
Your result is not decided inside a private broker database.
STRIKE records the trade onchain and settles it on a valid Pyth price update. The transaction, the settlement price, and the outcome can all be inspected publicly — by you, or by anyone.
