I'll provide you with a basic structure for the frontend, backend, and Telos Solidity smart contract code for the "Galaxy Miners: Quest for Telos" game. This will be a simplified version to get you started, and you can expand on it as needed.

Let's break this down into three main parts:

1. Frontend (React with Phaser.js)
2. Backend (Node.js with Express)
3. Smart Contract (Solidity for Telos)

Let's start with the frontend and backend:

Now, let's create the Solidity smart contract for the Telos blockchain:

This smart contract provides the basic functionality for the Galaxy Miners game, including:

1. Claiming planets
2. Creating and upgrading ships
3. Mining resources
4. Withdrawing resources as TLOS tokens

To use this contract, you'll need to deploy it on the Telos blockchain and interact with it using a Telos-compatible wallet like Scatter or Anchor.

Remember, this is a basic implementation and would need further development, security audits, and optimizations before being production-ready. You'd also need to integrate the frontend with the smart contract using a library like ethers.js or web3.js, and implement proper error handling and user feedback throughout the application.

I'll provide you with a step-by-step guide to set up the "Galaxy Miners: Quest for Telos" project in your local folder. This guide will cover setting up both the frontend and backend, as well as preparing for smart contract integration.

Here are the steps to set up the "Galaxy Miners: Quest for Telos" project in your folder:

1. Create the project folder:

   mkdir galaxy-miners cd galaxy-miners

2. Set up the frontend (React) project:

   npx create-next-app@latest frontend --typescript cd frontend

3. Install additional frontend dependencies:

   npm install phaser react-router-dom @types/react-router-dom ethers

4. Set up the backend (Node.js) project:

   cd .. mkdir backend cd backend npm init -y npm install express cors dotenv npm install --save-dev typescript @types/express @types/cors @types/node ts-node nodemon

5. Create a tsconfig.json file in the backend folder:

   { "compilerOptions": { "target": "es6", "module": "commonjs", "outDir": "./dist", "strict": true, "esModuleInterop": true }, "include": ["src/**/*"] }

6. Create the backend folder structure:

   mkdir src touch src/server.ts

7. Update the package.json in the backend folder to include start scripts:

   "scripts": { "start": "node dist/server.js", "dev": "nodemon src/server.ts", "build": "tsc" }

8. Copy the provided frontend code into the appropriate files in the frontend/src folder:

   • App.tsx
   • components/Game.tsx
   • components/Marketplace.tsx
   • components/Wallet.tsx
9. Copy the provided backend code into backend/src/server.ts.

10. For the smart contract:

    • Install Truffle (if not already installed):

      npm install -g truffle

    • Create a new folder for the smart contract:

      cd .. mkdir smart-contract cd smart-contract truffle init

    • Install OpenZeppelin contracts:

      npm install @openzeppelin/contracts
    • Copy the provided GalaxyMiners.sol contract into the contracts folder.

11. Update the frontend to connect with the backend:

    • In the frontend folder, create a .env.local file:

      NEXT_PUBLIC_API_URL=http://localhost:3001
    • Update API calls in components to use process.env.NEXT_PUBLIC_API_URL.

12. Set up environment variables for the backend:

    • In the backend folder, create a .env file:

      PORT=3001 TELOS_RPC_URL=https://testnet.telos.net/evm

13. Install dependencies for Telos integration (in the backend folder):

    npm install @eosio/eosjs

14. To run the project:

    • Start the backend:

      cd backend npm run dev

    • In a new terminal, start the frontend:

      cd frontend npm run dev

15. To deploy the smart contract (when ready):

    • Configure Truffle for Telos deployment (update truffle-config.js).

    • Run:

      cd smart-contract truffle migrate --network telos

Remember to replace placeholder values (like API endpoints and contract addresses) with actual values as you develop and deploy your project.

This setup provides a basic structure for your "Galaxy Miners: Quest for Telos" project. You'll need to expand on this foundation, implementing game logic, integrating with the Telos blockchain, and adding more features as outlined in your game description.
