Gauntlet

A "last man standing" survival pool for the FIFA World Cup 2026, on Sui + Walrus.

Built for the Tatum × Walrus hackathon (May 23 – June 6, 2026). Launching 5 days before kickoff.

How it works

1. Pick a player. Deposit 1 SUI. Mint a Survival Pass NFT tied to a real-world footballer.
2. Get your target. The AI Game Master assigns your player a stat target — score a goal, complete 4 tackles, keep a clean sheet, whatever fits their role. Superstars get brutal targets. Workhorses get reachable ones.
3. The match happens. Real-world stats land on Walrus. If your player hit their target, your pass survives. If not, it burns and your stake locks into the pot for the survivors.
4. Cash out or ride. Survivors choose: take a guaranteed proportional share of the pot now, or let it ride into the next matchday for a fatter multiplier.

The more passes die, the more each survivor's share grows.

Pivot history

This repo was originally Proof-of-Receipt (a tamper-proof web snapshot service). Pivoted to Gauntlet on June 1 with 5 days remaining. The original scaffold (Next.js + dApp Kit + Tailwind) carried over; the snapshotter and receipt module were deleted. See gemini-chat.txt for the brainstorm that led here.
