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.

Deep Dive into the OpenZeppelin Library

We have been referring to the OpenZeppelin libraries in some places in Chapter 3, Control Structures and Contracts, in Chapter 4, Learning MetaMask and Remix, and in the sample Solidity code we discussed in those chapters. In this chapter, we will look into the Solidity contract files that OpenZeppelin provides. The OpenZeppelin Solidity contract files and libraries are open source. These have been tested, audited, and used in many Ethereum Decentralized Applications (DApps). The OpenZeppelin project files are maintained by the Zeppelin company, and the libraries were developed to ensure high-quality code and security standards.

After completing this chapter, you will be able to install and use the OpenZeppelin library contract files in your project. You will be able to decide which library files you want to bring in...
