How it works

  1. 01
    Tap in the feed

    The Blink unfurls wherever links unfurl. Pick a side — one tap, no app, no install. The feed is the venue.

  2. 02
    Sign on devnet

    Your pick is a real Solana transaction: a 0-lamport SPL memo referencing the public board account. That memo IS the database.

  3. 03
    Streak grows

    The fixture resolves the round. Call it right and the streak ticks up — then share your card straight back into the feed.

What's real, what's replayed

Real

Every prediction is a signed Solana transaction — devnet for the demo game, mainnet for the live Final. Streaks and the leaderboard are reconstructed purely from chain history against one public board account — nothing else. There is no database.

Replayed

Demo match events come from a recorded, TxLINE-shaped synthetic fixture on a compressed 90-second loop — labeled SYNTHETIC everywhere it appears. A live TxLINE stream plugs in at one seam and nothing downstream changes; the Final market already runs on it.

Streak board

Every wallet, ranked from chain state.

Live odds

TxLINE consensus 1X2, ~60s delay.
