Certified Web3 Development

About Course

Dive into the future of the internet with our Certified Web3 Developer online course. Designed for developers, entrepreneurs, and tech enthusiasts, this program equips you with the essential skills to build decentralized applications (dApps), smart contracts, and blockchain-based solutions.
Whether you’re new to blockchain or seeking to deepen your expertise, this course offers a comprehensive, hands-on curriculum covering Web3 fundamentals, Ethereum, Solidity programming, DeFi, NFTs, and emerging trends like DAOs and Layer 2 scaling.

Through a blend of video lectures, real-world projects, quizzes, and mentorship, you’ll graduate with a portfolio-ready dApp and the recognized Certified Web3 Developer credential — preparing you for roles in blockchain development, Web3 startups, consulting, and beyond.

Blockchain Basics: Understand the fundamentals of blockchain technology, consensus mechanisms, and decentralized networks.
Ethereum & Smart Contracts: Learn Solidity, build and deploy smart contracts on Ethereum, and work with token standards (ERC-20, ERC-721).
dApp Development: Build decentralized applications (dApps) with Web3.js and Ethers.js, and integrate them with wallets like MetaMask.
NFTs: Create, mint, and trade NFTs, and build an NFT marketplace.
DeFi: Explore decentralized finance (lending, borrowing, yield farming), and develop DeFi applications.
DAOs: Learn how to create and manage Decentralized Autonomous Organizations (DAOs) with governance tokens and voting mechanisms.
Layer 2 Solutions: Implement scalability solutions like Optimistic Rollups and zk-Rollups in your dApps.
Security Best Practices: Understand smart contract vulnerabilities and conduct security audits.
Real-World Projects: Build and deploy real-world blockchain applications and gain practical experience.
