Blockchain & Web3 Dev

Build decentralized applications. Master Solidity smart contracts, the EVM architecture, and dApp integration using Hardhat and Ethers.js.

Web3 is the decentralized web. This course teaches you to build Smart Contracts on the Ethereum blockchain using Solidity. You will understand the Ethereum Virtual Machine (EVM), gas optimization, and security best practices. Learn to deploy contracts using Hardhat, test them thoroughly, and build front-ends that interact with the blockchain using Ethers.js and React. Whether for DeFi, NFTs, or DAOs, this is your entry into blockchain engineering.
