Solidity Programming Essentials. - Second Edition

Overview of this book

Solidity is a high-level language for writing smart contracts, and the syntax has large similarities with JavaScript, thereby making it easier for developers to learn, design, compile, and deploy smart contracts on large blockchain ecosystems including Ethereum and Polygon among others. This book guides you in understanding Solidity programming from scratch. The book starts with step-by-step instructions for the installation of multiple tools and private blockchain, along with foundational concepts such as variables, data types, and programming constructs. You’ll then explore contracts based on an object-oriented paradigm, including the usage of constructors, interfaces, libraries, and abstract contracts. The following chapters help you get to grips with testing and debugging smart contracts. As you advance, you’ll learn about advanced concepts like assembly programming, advanced interfaces, usage of recovery, and error handling using try-catch blocks. You’ll also explore multiple design patterns for smart contracts alongside developing secure smart contracts, as well as gain a solid understanding of writing upgradable smart concepts and data modeling. Finally, you’ll discover how to create your own ERC20 and NFT tokens from scratch. By the end of this book, you will be able to write, deploy, and test smart contracts in Ethereum.

Summary

There was a lot of substance covered in this chapter. To give you a quick recap, we saw how Ethereum nodes implement JSON-RPC endpoints that can be connected using WS, IPC, and RPC. In this chapter, we discussed various forms of networks – public, main, test, and private. The chapter also discussed and implemented a private network. We followed steps to create a development environment that will be used in subsequent chapters. We also focused on deploying multiple tools and utilities on a Windows operating system. While each tool has its own workings and functionality, some tools might eventually do the same thing – for example, a Geth-based private chain and ganache-cli are essentially Ethereum nodes but with differences. The deployment of Geth, the Solidity compiler, ganache-cli, the web3 framework, and MetaMask were covered in this chapter. While some of you will like working with ganache-cli, others will be interested in using a private Geth-based Ethereum...
