Mechanics

Three steps to a position

01

Pick a market

Choose an asset, a strike, and an expiry from 15 seconds to four hours. The strike is the price your position is measured against.

BTCstrike $64,00060s
02

Choose above or below

Bet the price finishes above or below the strike. Your payout is fixed and quoted up front — the pool prices each side off its current skew.

03

Settles itself, onchain

At expiry, the first Pyth price decides the outcome. Winners are paid the fixed amount automatically. No oracle discretion, no counterparty to chase.

Transparency

Settlement you can verify, not trust

Every position is collateralised in full and resolved by code. The contract reads one specific Pyth price — the first published at or after your expiry — so no one, including us, chooses the number that decides your trade.

Items marked pending are not yet live and are shown honestly. STRIKE is in preview; nothing here is a production claim.
