PRIVATE PREDICTION POOLS · SETTLED BY TXLINE

Pick with friends.
Not the crowd.

Veil is built for fan groups to lock match picks before kickoff so nobody can copy the crowd. TxLINE proves the final score, Solana settles the pool, and losing tickets can stay sealed.

Your choice is sealed, not your wallet.

Before reveal, Solana records your address, fixed test stake, timing, market, and a SHA-256 commitment—but not your choice or nonce. A winning reveal publishes both. A losing ticket can remain unopened forever.

Historical replay.This demo uses a real historical TxLINE proof whose result was already knowable. It demonstrates Veil's commitment and proof-settlement path; it is not a live prediction-privacy test.
