This is the code repository for Learn Ethereum, published by Packt.

Build your own decentralized applications with Ethereum and smart contracts

Learn Ethereum is ideal for anyone who wants to do an ultra-learning on Ethereum blockchain technology and build end-to-end decentralized applications using smart contract and Ethereum. The hands-on examples will help novices master blockchain and Ethereum in a quick, effective and easy way.

This book covers the following exciting features: Understand the concepts of blockchain and cryptocurrency Master Ethereum development tools such as Truffle, Remix IDE and Infura Delve into smart contract development Develop DApps frontend using Node.js, React.js, and Web3js API Learn Etherscan and other tools to secure and monitor smart contracts Develop and debug smart contracts by working with Remix Apply Truffle suite to compile, migrate, and unit test smart contracts Explore smart contracts such as ERC20 token and decentralized digital market

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

componentDidMount = async () => {
        const web3 = await getWeb3();
        const contractInstance = await getInstance(web3);
...
        this.setState({ contractInstance: contractInstance });
      } 

Following is what you need for this book: This book is for all developers and architects who want to explore Ethereum blockchain fundamentals and get started with building real-world decentralized applications. Knowledge of an object-oriented programming language such as JavaScript will be useful but not mandatory.

With the following software and hardware list you can run all code files present in the book (Chapter 1-11).
