⚡ World Cup Momentum Pool — WE ARE 26

X Cup Hackathon — OKX X Layer (2026 FIFA World Cup)

Slogan: WE ARE 26

Pick the dominant team in each half. Not predictions — momentum.

---

🏆 What is it?

A real-time GameFi dApp for the 2026 FIFA World Cup, themed around the official WE ARE 26 campaign. Before each match half, users deposit into Team A or Team B. During the half, real match events (goals, shots, corners, cards) accumulate momentum points. At half-time, the team with more momentum wins. Winners split the pot.

⚽ Point System

Event	Points	Why
Goal	+5	Biggest swing — changes the game
Woodwork	+2	So close — crowd erupts
Shot on Target	+1	Pressure building
Corner	+1	Territorial dominance
Foul	-1	Breaks flow
Yellow Card	-3	Team walks a tightrope
Red Card	-5	Match-defining negative

🏗️ Architecture

Frontend (Next.js → Vercel)
  ├── Live momentum bar (polls every 15s)
  ├── Pool deposit UI (wagmi → X Layer)
  └── Event feed (real match events)

Backend (Vercel Cron → /api/cron/settle)
  └── At half-time: settles the on-chain pool

Contracts (X Layer)
  ├── MomentumPool.sol
  ├── MomentumPoolFactory.sol
  └── 10 Foundry tests passing

🚀 Deploy

1. Contracts → X Layer

cd contracts
cp .env.example .env   # set PRIVATE_KEY
bash deploy.sh testnet

Export the factory address — you'll need it for Vercel.

2. Frontend → Vercel

cd frontend
pnpm install
pnpm dev

Vercel deployment:

1. Import github.com/latest63/Latest-MomentumPool
2. Root directory: frontend/
3. Framework: Next.js
4. Add env vars:
   • PRIVATE_KEY — deployer wallet
   • FACTORY_ADDRESS — from contract deployment
   • XLAYER_RPC — https://testrpc.xlayer.tech

Vercel Cron runs /api/cron/settle every 2 min to auto-settle pools.

🧪 Tests

cd contracts
forge test -vv   # 10/10 passing
