⚙️ Setup Instructions

1. Clone the repository

git clone https://github.com/Anantdadhich/fruityslice.git

2. Install dependencies

npm install

3. Create your .env file

Create a .env file in the root of your project and fill in:

PAYER_WALLET=your_base58_encoded_secret_key
JWT_SECRET=your_jwt_secret
JWT_EXPIRY=1h
AUTH_TOKEN=static_auth_token_if_applicable
VITE_BACKEND=http://localhost:3001

4. Run the Solana setup (Devnet)

Run your wallet/token setup script to generate:

• ✅ House Wallet Address
• ✅ Token Mint Address
• ✅ House Token Account

Save those and update the frontend/backend with:

const TOKEN_MINT = new PublicKey("your_token_mint");
const PAYER = Keypair.fromSecretKey(bs58.decode(process.env.PAYER_WALLET));
const HOUSE_WALLET = PAYER.publicKey;

🧠 Game Logic (Frontend)

• The frontend renders the Fruit Ninja game
• Player score is tracked
• On game over, players can claim rewards
• handleClaim() sends the score to the backend, which validates it, calculates rewards, and triggers a token transfer

---

🛠 Backend (server.js)

Handles:

• ✅ JWT authentication
• ✅ POST /api/login — returns JWT token
• ✅ POST /api/transfer-tokens — transfers SPL tokens to player’s wallet based on score

---

🎮 Reward System

export const getSliceReward = (score) => {
  if (score < 10) return 0;
  if (score < 20) return 0.005 * LAMPORTS_PER_SOL;
  if (score < 50) return 0.01 * LAMPORTS_PER_SOL;
  if (score < 100) return 0.03 * LAMPORTS_PER_SOL;
  return 0.05 * LAMPORTS_PER_SOL;
};

💡 Notes

• Everything runs on Solana Devnet, no real SOL involved.
• Make sure to fund your house wallet with devnet SOL using:
• there is error in claim rewards so anyone wants to contribute contribute there
• In future we can add leaderboard logic proper auth where the user in month have good score according to leaderboard the user can win nft
• we will shift to mainnet due to cost issues or developer friendly i try to make it in devnet
