Rules & Resolution
Draft · Updated 20 October 2026
Event contracts
Each market lists its resolution condition and oracle source. The specified official publication determines the final outcome.
Buy and hold
Positions remain open until settlement. Early selling and opposing positions on the same market are unavailable.
60-second rounds
A round compares its final observed price with the lock price. Trading closes in the final 15 seconds and quoted multipliers freeze at that lock, so payouts can never exceed the net distributable pool after the platform rake. Only one position per round is permitted. Flash multipliers start at 1.90x and incorporate the platform rake (currently 5%), set in the admin trading rules.
Feed availability
Backup prices are indicative only. Flash trading pauses while the live feed is unavailable. Real-money settlement requires a trusted, durable price source.
Payouts
Projected payout equals trade size multiplied by the quoted multiplier. An out-of-the-money outcome returns zero.
