BEP-20 Play-to-Earn en BNB Chain

Most Web3 tutorials show you how to deploy a token. Few show you how to build a game around it with real users playing and earning.
I built PlayMidas — a live Play-to-Earn game on BNB Chain with a BEP-20 token (MIDAS/MDS), Firebase auth, 4 minigames, wallet registration, and an admin panel. Then I packaged the entire foundation into a starter kit.
The stack

BEP-20 token on BNB Chain — verified on BSCScan
Solidity smart contract — 30M token supply
Firebase Auth — user authentication
Firestore — game state, scores, wallet registry
Vanilla JavaScript — frontend, no heavy framework
4 minigames — ready to extend or replace
Admin panel — manage users, balances, rewards

Why BNB Chain and not Ethereum?
Gas fees. Ethereum mainnet makes microtransactions in a game unviable. BNB Chain gives you EVM compatibility with fees low enough to actually reward players without burning the treasury.
What's inside
A verified BEP-20 smart contract ready to deploy, complete Firebase Auth and Firestore integration, 4 working minigames connected to the reward system, wallet registration flow so users link their BNB wallet to their game account, an admin panel to manage the economy, and full setup documentation.
The hardest part
Connecting Web2 (Firebase user accounts) with Web3 (on-chain wallets) cleanly. Users shouldn't need to understand blockchain to play — the starter kit abstracts this with a wallet registration flow that links Firebase UID to wallet address. Simple for the user, solid on the backend.
Who this is for

Web3 devs who want a working Play-to-Earn foundation without starting from zero
Developers building token-based games or reward systems
Anyone who wants a verified BEP-20 token with a real use case attached

Get it
PlayMidas is live at playmidas.xyz with real players and a verified contract on BSCScan.
