🏀 Flow Fantasy Fusion ⚡

AI-powered cross-ecosystem fantasy sports dApp on Flow blockchain with automated settlements

🌟 Overview

Flow Fantasy Fusion is an AI-powered, cross-ecosystem fantasy sports decentralised application (dApp) built entirely on the Flow blockchain.
It introduces a fully transparent, automated, and composable fantasy league experience that unites blockchain technology, AI-driven lineup optimization, and Forte’s automated transaction scheduling — delivering a next-generation fantasy sports experience without centralized intermediaries.

Players can create custom leagues, stake Flow tokens or NFTs (like NBA Top Shot moments), and let an AI system suggest the optimal team lineup based on player performance data, NFT values, and risk preferences.
Once the game concludes, Forte Scheduled Transactions automatically trigger on-chain settlements and payouts, eliminating manual intervention and ensuring full transparency.

💡 Problem Statement

Fantasy sports platforms today suffer from several core issues:

• Centralized and opaque scoring systems that reduce trust and transparency.

• Manual settlements that delay payouts and cause friction between participants.

• Ecosystem fragmentation — tokens and NFTs cannot coexist within a single fantasy system.

• Limited automation, requiring human oversight at every step.

These limitations create inefficiencies, bias, and a poor user experience for Web3 enthusiasts.

🚀 Our Solution

Flow Fantasy Fusion redefines fantasy gaming through a trustless, automated, and AI-assisted design powered by Flow and Forte.

Key Innovations:

1. AI-Driven Lineup Recommendations

   • A rule-based AI engine that evaluates player stats, NFT value, and performance consistency to recommend optimal lineups with explainable reasoning.

   • Three strategy modes: Balanced, High-Risk, and Conservative.

   • Outputs include expected score, confidence score, and rationale.

2. Cross-Ecosystem Asset Staking

   • Players can stake FLOW, FUSD, or USDC tokens — or even NBA Top Shot NFTs — as their entry assets.

   • Smart contracts handle escrow management, token validation, and stake limits.

3. Automated Settlements via Forte

   • Forte Actions allow the creation of composable workflows such as “Stake and Schedule Settlement.”

   • Forte Scheduled Transactions automatically trigger settlements and distribute winnings without human action.

4. On-Chain Transparency

   • All league operations, transactions, and prize distributions are executed on the Flow testnet, viewable in Flowscan.

   • Contracts emit events for every major state change (stake, settlement, payout).

🧱 Technical Architecture

Flow Fantasy Fusion is composed of three major layers:

Frontend (React + FCL) → Backend (Node.js + Express) → Blockchain (Flow + Cadence) → AI Service (Python + Flask)

Components

• Frontend: React + Tailwind CSS + Flow Client Library (FCL) for wallet integration (Blocto, Lilico).

• Backend: Node.js + Express API with rate limiting, caching (NodeCache), and security middleware (Helmet).

• AI Engine: Flask service executing a rule-based algorithm trained on fantasy scoring metrics.

• Smart Contracts (Cadence):

  • LeagueFactory — handles league creation and configuration.

  • StakingManager — manages token and NFT stakes securely.

  • Settlement — executes prize distribution using scheduled transactions.

Forte Integration

• Forte Actions: Composite JSON-defined actions (e.g., stake and schedule).

• Scheduled Transactions: Time-based settlement triggers that execute autonomously on the blockchain.

✨ Core Features

🏆 League Management

• Create and manage leagues with custom parameters (2–100 players).

• Define entry fees, start/end times, and supported assets.

💰 Multi-Asset Staking

• Supports FLOW, FUSD, USDC, and NFTs.

• Enforced stake limits and on-chain escrow validation.

🤖 AI Lineup Suggestions

• Rule-based model scoring players using multiple weighted factors:

  • 45% — Recent performance

  • 30% — NFT market value

  • 15% — Consistency metrics

  • 10% — Trending data

• Generates transparent and explainable lineup recommendations.

⚡ Automated Settlements

• Forte’s Scheduled Transactions execute at the game end.

• Smart contracts calculate final scores and distribute payouts automatically (60% / 25% / 15%).

🔒 Security Features

• Reentrancy protection and access control mechanisms.

• Token whitelisting (FLOW, FUSD, USDC only).

• Admin-only functions for contract management.

• Escrow validation before payouts.

📊 Dashboard

• Real-time stats: active leagues, total stakes, winnings.

• Live wallet balance and participation history.

🔗 Ecosystem Integration

🧠 AI Algorithm Details

Rule-Based Model:

• Uses performance datasets and NFT values to rank available players.

• Produces a lineup with an expected total score and confidence coefficient.

• Supports three optimization modes:

  • Balanced: Moderate risk/reward.

  • High-Risk: Targets high-upside players.

  • Conservative: Focuses on stable performers.

📜 Judging Criteria Alignment

🧩 Example Workflow

1. User connects Flow wallet via FCL.

2. User creates or joins a fantasy league.

3. User stakes tokens/NFTs (escrowed by StakingManager).

4. AI generates optimized lineup suggestion.

5. Forte Action “Stake and Schedule Settlement” schedules automatic payout.

6. After game end, Forte Scheduled Transaction triggers settlement.

7. Smart contract distributes winnings on-chain to top 3 players.

Everything — from staking to payout — happens transparently, on-chain, and automatically.

🔮 Future Enhancements

Phase 2 – Post-Hackathon:

• 🔗 Data Oracles: ESPN or Chainlink for live score feeds.

• 🧠 Machine Learning Models: LSTM and reinforcement learning for lineup prediction.

• 💬 Social Features: League chats, XMTP messaging, and Lens Protocol sharing.

• 💸 Advanced Staking: Dynamic entry fees, liquidity pools, and yield-based prize pools.

• 📱 Mobile App: React Native version with push notifications.

• 🌉 Cross-Chain Expansion: Polygon and Arbitrum compatibility.

Phase 3 – Production:

• Smart contract audit (CertiK, Trail of Bits).

• Legal compliance and licensing.

• DAO-based governance for league management.

• Partnerships with Flow-based sports ecosystems.
