✅ Build a Free Crypto Token on Polygon or BNB Testnet
🚀 Create your own custom crypto token on testnets – no fees, no real money required!
🔍 About the Task
This task gives you real-world blockchain development experience — without spending a single rupee! You’ll create a smart contract for a crypto token using Solidity, then deploy it on Polygon Mumbai or BNB Chain Testnet, both of which use free test tokens (not real money).
This is a perfect first step into DeFi, DAOs, and Web3 careers.
✅ What You’ll Do
- ✅ Write a custom ERC-20 or BEP-20 token using Solidity and OpenZeppelin.
- ✅ Deploy it on Polygon Mumbai Testnet or BNB Chain Testnet using free test crypto from faucets.
- ✅ Host your smart contract code and logo on GitHub.
- ✅ Share your testnet token in MetaMask and on a blockchain explorer.
- ✅ Optional: Document the token’s use-case or future roadmap as if it were a real project.
🧠 Skills You’ll Gain
- Smart contract development with Solidity
- Working with Ethereum Virtual Machine (EVM) chains
- Using developer tools like Remix, MetaMask, and faucets
- Deploying to testnets and viewing results on explorers
- Building a personal Web3 GitHub portfolio
