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.

Chapter 10. Debugging Contracts

This is the last chapter of the book. By now, we have looked at Solidity and Ethereum from a conceptual standpoint, developed and authored Solidity contracts, and tested them. The only thing that was not discussed was troubleshooting contracts. Troubleshooting is an important skill and exercise when dealing with any programming language. It helps in finding issues and solving them efficiently. Troubleshooting is both an art and a science. Developers should learn the art of troubleshooting through experience as well as by exploring details behind the scenes using debugging. This chapter will focus on debugging coding issues related to Solidity contracts.

This chapter covers the following topics:

  • Debugging contracts
  • Debugging contracts using Remix and Solidity events
