Solidity Programming Essentials

Overview of this book

Solidity is a contract-oriented language whose syntax is highly influenced by JavaScript, and is designed to compile code for the Ethereum Virtual Machine. Solidity Programming Essentials will be your guide to understanding Solidity programming to build smart contracts for Ethereum and blockchain from ground-up. We begin with a brief run-through of blockchain, Ethereum, and their most important concepts or components. You will learn how to install all the necessary tools to write, test, and debug Solidity contracts on Ethereum. Then, you will explore the layout of a Solidity source file and work with the different data types. The next set of recipes will help you work with operators, control structures, and data structures while building your smart contracts. We take you through function calls, return types, function modifers, and recipes in object-oriented programming with Solidity. Learn all you can on event logging and exception handling, as well as testing and debugging smart contracts. By the end of this book, you will be able to write, deploy, and test smart contracts in Ethereum. This book will bring forth the essence of writing contracts using Solidity and also help you develop Solidity skills in no time.

Development with Truffle


Using Truffle is quite simple. Truffle provides lots of scaffolding code and configuration by default. Developers need only to reconfigure some of the out-of-the-box configuration options and focus on writing their contracts. Let's take a look at the following steps:

  1. The first step is to create a project folder that will hold all projects- and Truffle-generated artifacts.
  1. Navigate to that folder and enter the init command. The init command refers to the initiation and initialization of Truffle within the folder. It will generate appropriate folders, code files, configuration, and linkage within the folder as shown in the following screenshot:

The preceding code results in a generated folder structure as shown in the following screenshot:

Let's take a look at the following folders shown in the preceding screenshot: 

  • The contracts folder contains a single file named migrations.sol. It contains a contract responsible for deploying custom contracts to an Ethereum network...
