Capabilities

Everything a prediction product needs, already built

01YES / NO markets
Bet on any event. The share price is the probability the market gives it.
02LMSR pricing
The market maker quotes both sides and supplies liquidity. No order book to fill.
03Cash-out
Players sell a position back at the live price any time before close.
04Limit orders
Auto-buy when a side reaches the price the player set.
05Parlays
Combine several markets into one bet and the odds multiply.
06Price alerts
Ping a player the moment a market hits a price they care about.
07Multi-outcome events
One event, many linked options — the player picks one of N.
08Live feed & leaderboard
A running bet feed and a P&L leaderboard keep players engaged.
09On-chain settlement
Price markets auto-resolve from the Pyth oracle; a hash of every outcome is sealed on Solana.
10AI analytics
A probability estimate, factor breakdown and a pick on every market — built into the UI.
01

What the engine handles

LMSR pricing
The market maker keeps prices and liquidity on its own. No order book, no counterparty to find.
On-chain settlement
A hash of every settled market is published to Solana. Rewrite a result after the fact and the root stops matching, in public.
Your money and users
Balances and accounts stay on your side. The engine is non-custodial and never touches the funds.
Revenue from fees
You take a cut of every bet. Whoever created the market earns too.

FAQ

Do players need crypto wallets?+

No. With the seamless-wallet setup they bet on their casino or app balance. No wallets, no seed phrases.

How do outcomes get settled?+

Price markets close automatically off the Pyth oracle; event markets are called by the operator. A hash of every settled market is published to Solana, so a result cannot be swapped after the fact.

How fast can we go live?+

Usually a few days: a key plus an iframe, SDK, or raw REST/WS. Message us and we'll point you at the right path.

Who holds the money?+

You do. The engine is non-custodial: balances and users stay with you, and it never holds funds.
