Learn Ethereum Dapp in this full tutorial for beginners. This course teaches how to build decentralized applications on the Ethereum Blockchain. We are going to build 5 Ethereum Dapps. For each of them, we will:
- Develop smart contracts
- Test smart contracts
- Build a web frontend to interact with the smart contract
The course covers:
- The architecture of Dapps
- Solidity, the programming language for Ethereum smart contract
- Remix, the online IDE for Solidity
- Truffle, the framework for Solidity smart contracts
- Ganache, the local development Blockchain
- Web3, the JS library to integrate a Dapp frontend
- Metamask, the Ethereum wallet used by most Dapps (browser extension)
- Deployment to public testnet (Ropsten) and mainnet, using Infura API
Requirements:
- NodeJS v10
- Works on both Windows, Linux and Mac
