Create ERC20 Token (Final Part – Part 7) | Approval, Transfer, Time & Edge Case Helper Tests

Description

🧠 Learn How to Test Solidity Smart Contracts Using Hardhat (ERC20 Token Testing Guide) In this tutorial, you’ll master how to test Solidity smart contracts with Hardhat — the most popular and powerful Ethereum development framework. This lesson covers testing ERC20 token functions such as approve, allowance, transfer, transferFrom, events, name, symbol, and more. If you want to build secure, production-ready Web3 applications, understanding smart contract testing is essential. Whether you’re creating ERC20 tokens, DeFi protocols, NFT projects, or full-stack blockchain dApps, this video will help you write reliable, bug-free, and fully tested Solidity smart contracts. --------------------------------------------- 🔥 What You’ll Learn: ✅ How to set up and run a Hardhat testing environment ✅ Write unit tests for ERC20 name, symbol, approve, allowance, and transfers ✅ Test Transfer and Approval events the correct way ✅ How transferFrom works and how to validate token behavior ✅ Debugging and automating test workflows ✅ Best practices for Solidity + Hardhat testing --------------------------------------------- 🌐 OFFICIAL WEBSITE (Tutorials, Source Code, Courses): 👉 VISIT: https://webdevlab.org Your hub for Web3, Blockchain, and Full-Stack Development guides, code samples, and real-world projects. --------------------------------------------- 📦 Source Code: GitHub – Hardhat ERC20 Testing Example https://github.com/web-dev-lab-official/web3-journey/tree/master/01-ethereum-erc20-token --------------------------------------------- 📚 Related Tutorials: NFT Rental Marketplace with Python APE + Solidity https://www.youtube.com/playlist?list=PLDbgPtNOy-yDXHi5i0oK4Zq6SdH8jlauu FastAPI and Vue.js CRUD https://www.youtube.com/playlist?list=PLDbgPtNOy-yD4rDHFWwqw0v3dHY4s5TBy FastAPI, Socket.io, Redis – Real-Time Football Insights https://www.youtube.com/playlist?list=PLDbgPtNOy-yBWtZ-zG91wUd-3YqerdJdL --------------------------------------------- 🔗 Follow Me for More Web3 & Blockchain Dev Content: X (Twitter): https://x.com/shayon_md LinkedIn: https://linkedin.com/in/md-samsuzzoha --------------------------------------------- 💬 Don’t forget to LIKE, COMMENT, and SUBSCRIBE for weekly tutorials on Web3, Solidity, Hardhat, Blockchain Development, and Full-Stack Engineering! #Hardhat #Solidity #ERC20 #SmartContractTesting #TokenTesting #EthereumDevelopment #Web3Developer #BlockchainDevelopment #CryptoDeveloper #SmartContracts #HardhatTesting #SolidityTesting #WebDevLab #webdevlab
