Smart Contract Development with blocApps

COURSE OVERVIEW

Master smart contract development through practical blocApp integration. This developer-focused course teaches you to build, test, and deploy blockchain applications using pre-built blocApps as building blocks. Learn Solidity fundamentals, smart contract patterns, and how to create production-ready dApps by combining modular blocApps. Whether you’re a web developer entering Web3 or an experienced blockchain developer looking to accelerate development with modular components, this course provides hands-on training with real smart contracts on blocLabs’ HyperLedger Besu network.

WHAT YOU’LL LEARN

• Solidity Fundamentals: Variables, functions, modifiers, events, and inheritance
• Smart Contract Patterns: Factory, proxy, upgradeable contracts, access control
• blocApp Architecture: Understanding modular smart contract design
• Contract Integration: Combining multiple blocApps into cohesive dApps
• Testing & Security: Hardhat testing, security best practices, auditing
• Deployment: Deploy to HyperLedger Besu via blocLabs infrastructure
• Frontend Integration: Connect React/Next.js apps to smart contracts
• Gas Optimization: Reduce transaction costs and improve efficiency
