Mastering Blockchain Programming with Solidity

By: Jitendra Chittoda

Overview of this book

Solidity is among the most popular and contract-oriented programming languages used for writing decentralized applications (DApps) on Ethereum blockchain. If you’re looking to perfect your skills in writing professional-grade smart contracts using Solidity, this book can help. You will get started with a detailed introduction to blockchain, smart contracts, and Ethereum, while also gaining useful insights into the Solidity programming language. A dedicated section will then take you through the different Ethereum Request for Comments (ERC) standards, including ERC-20, ERC-223, and ERC-721, and demonstrate how you can choose among these standards while writing smart contracts. As you approach later chapters, you will cover the different smart contracts available for use in libraries such as OpenZeppelin. You’ll also learn to use different open source tools to test, review and improve the quality of your code and make it production-ready. Toward the end of this book, you’ll get to grips with techniques such as adding security to smart contracts, and gain insights into various security considerations. By the end of this book, you will have the skills you need to write secure, production-ready smart contracts in Solidity from scratch for decentralized applications on Ethereum blockchain.

Setting up the Truffle project

We learned about Truffle in Chapter 5, Using Ganache and the Truffle Framework. To set up a new Truffle project, we have to do the following:

  1. Execute the following command in an empty folder:
$ truffle init

This will initialize the Truffle project-related files and folders under the current directory.

  1. Initialize the npm packages in the Truffle project. To enable the project to install npm packages, you will need to execute the following command:
$ npm init

The command will ask for certain details related to your package that you can provide, and it will create a package.json file under the current folder.

  1. Next, we need to install the dependencies of the project that we are going to use. As we have designed the contract's architecture, looking at that, we would need libraries from OpenZeppelin.
