TxODDS World Cup Hackathon

Whistly was built for the TxODDS World Cup Hackathon — a World Cup hackathon for builders who want real-time match data wired into real products. $50K across three tracks: markets, trading agents, and fan experiences — all powered by TxODDS' live football API on Solana. Whistly competes in the markets and fan experiences tracks.

The 2026 tournament — and the free World Cup API tier — have now ended. Every knockout market on the homepage was settled from real final scores while the feed was live.

Demo notice. Whistly is an independent hackathon demo. Demo tokens have no monetary value, and simulated TxLINE-compatible data may be used where live credentials are unavailable.
