Galactic Invaders — Play-to-Earn Arcade Game with BEP-20 Token | Full Source Code

Launch Your Own Blockchain Arcade Game on BNB Smart Chain

Galactic Invaders is a complete, ready-to-deploy Play-to-Earn retro arcade game built on BNB Smart Chain (BSC). Players connect their wallets, battle waves of alien invaders in a 90-second timed round, and compete on a weekly leaderboard for token rewards. Comes with a custom BEP-20 token, smart contracts, React frontend, and full documentation — everything you need to go live.

This is not a template or a boilerplate. It's a finished product with working smart contracts, a real game engine, wallet integration, and a token economy. Deploy the contracts, upload the frontend, and you have a live Web3 game.

What You Get

• 2 Smart Contracts — BEP-20 token (mintable, ownable) and game contract (sessions, leaderboard, weekly rewards)
• Full React Frontend — Arcade-style UI with animated home screen, live gameplay preview, leaderboard, how-to-play guide, and mute toggle
• HTML5 Canvas Game Engine — Space Invaders-style gameplay with pixel art sprites, parallax starfield, particle explosions, screen shake, 8-bit synthesized sound effects, and power-ups (shield, rapid fire, bomb)
• Multi-Wallet Support — Reown AppKit integration supporting MetaMask, TrustWallet, WalletConnect, Coinbase Wallet, and 300+ wallets
• Mobile Ready — Touch controls with on-screen buttons that appear automatically on mobile devices
• Anti-Tamper System — SHA-256 game hash submitted with every score to verify gameplay integrity
• Documentation Page — Built-in HTML documentation accessible at /documentation.html covering installation, deployment, customization, and troubleshooting
• No Backend Required — Fully static frontend + on-chain logic. Host anywhere: Vercel, Netlify, cPanel, any static host

How the Game Economy Works

1. Players connect a wallet and start a game session — 1 free play per day, or pay a set amount of your token for extra plays
2. Players play a 90-second arcade round, earning points by destroying aliens and clearing waves
3. After the round, the score is submitted on-chain with a tamper-proof hash
4. The top 50 scores appear on a public leaderboard
5. Every week, the contract owner distributes the reward pool to the #1 player
6. Leaderboard resets weekly — keeping players coming back

All values are configurable before deployment: token name, symbol, initial supply, play cost, weekly reward amount, game duration, difficulty settings, and more.
