Ethereum Blockchain Development Online Course

Ethereum Blockchain Development Online Course

This course provides a complete journey into Ethereum blockchain development, focusing on building decentralized applications (DApps), smart contracts, and digital assets. It begins with blockchain fundamentals and using the Remix IDE to read and write smart contracts, then progresses through hands-on projects like Blockchain Messenger to learn core data types. You’ll work on Smart Money projects covering deposits, withdrawals, and Ethereum transactions with Metamask, followed by Smart Wallet to explore mappings, structs, and advanced Solidity functions.

The course advances into ERC20 token sales, Web3.js integration, event handling, and modifiers, before diving into NFTs using Truffle for debugging and deployment. It concludes with alternative frameworks like Hardhat and Foundry. By the end, learners will be proficient in Solidity, smart contract development, and blockchain programming, with practical experience in creating real-world projects, including DApps and NFTs.

Who should take this Course?

The Ethereum Blockchain Development Online Course is ideal for blockchain enthusiasts, software developers, and IT professionals who want to build decentralized applications (dApps) and smart contracts on the Ethereum platform. It’s also suitable for entrepreneurs, researchers, and students interested in exploring blockchain technology, token creation, and decentralized finance (DeFi) solutions. Basic knowledge of programming (preferably in Solidity or JavaScript) and blockchain concepts is recommended for effective learning.
