Eleven AI Agents Running Live Football Prop Markets On-Chain

What it does The Eleven fields eleven autonomous AI personas that watch live football matches—possession swings, shot patterns, foul counts—and open binary prediction markets in real time on X Layer mainnet. Each market is a custom Uniswap v4 hook called PropMarketHook that pools OVER and UNDER stakes in USDT0, then pays winners proportionally from the losing side. Users enter gaslessly with a single EIP-712 signature, relayed by an in-app facilitator so they never handle gas tokens.

The interesting bit The hook rejects liquidity provision by construction—this is a stake aggregator, not an AMM—and binds the v4 pool lifecycle to a commit-reveal flow so agents cannot frontrun their own market parameters. The factory salt-mines a CREATE2 address to hit the exact 0x2A80 permission bitmap Uniswap v4 demands, verified in roughly 16K iterations on commodity hardware. It is a very specific marriage of prediction-market mechanics and pool hooks.

Key highlights

• Eleven BIP-44-derived agent wallets each adopt a tactical role—striker, sweeper, playmaker—and fire 2–4 markets per match within their assigned window.
• PropMarketHook enforces commit-reveal, dual-pool pari-mutuel settlement, and refund paths for voided markets; the contract suite reports 67/67 tests with full line, branch, and function coverage.
• Gasless entry via EIP-3009 transferWithAuthorization on USDT0; the README bills this as the first documented X Layer dapp using that flow.
• Tournament markets are designed to resolve through a Flap WorldCupResolver relay on BNB Chain with a guardian veto window, though the current live deployment uses an admin resolver.
• The Next.js 15 frontend renders the agents in a 3D stadium, supports Farcaster Mini App sharing, and exposes an MCP integration for external agent runtimes.

Caveats

• Live match data depends on third-party football APIs, and the README notes the team has already had to swap sources mid-hackathon to dodge free-tier rate limits.
• Farcaster native signing inside a cast is blocked until Farcaster hosts add X Layer to their supported chains; the frame currently launches the app but cannot settle stakes natively inside the feed.
• The 2026 tournament resolution pipeline is described as “planned” and “designed to anchor” to Flap’s BNB Chain resolver, while the current deployment relies on a centralized admin resolver.

Verdict Study this if you are building Uniswap v4 hooks, onchain prediction markets, or agentic DeFi workflows; give it a pass if you want a production-grade sportsbook—the tournament resolution plumbing is still on the drawing board and the oracle pipeline is not yet live.
