FIFA WORLD CUP 2026 · TRUSTLESS SETTLEMENT

Bet the match.
The whistle settles it.

Two people wager on a verifiable World Cup stat. Funds lock in a Solana escrow. When the match ends, a TxLINE Merkle proof · not an admin · releases the money to the winner.

How settlement works

01

Create a pact

Pick a fixture and a verifiable stat · goals, corners, cards, or a margin like “corners diff > 3”. Stake USDC; it locks in a program escrow.

02

Someone takes it

A counterparty stakes the matching side. Terms are committed on-chain. Now both stakes sit in a PDA neither side controls.

03

The proof settles it

At full time, anyone (or our keeper agent) submits TxLINE’s Merkle proof. The program CPIs validate_stat and pays the winner. No oracle, no admin.
