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.

Contract architecture design

Once you have the system specification written, the first thing is to find the right tools and libraries that should be used to build the project from scratch. It is always recommended that you look for existing libraries that are battle tested and easy to maintain in the project. The OpenZeppelin Solidity contract libraries provide many battle-tested contracts and libraries that are readily available to use in your project.

Our project requires ERC20 and crowdsale-related libraries, which are readily available in the OpenZeppelin library package. We have learned about these ERC20 and crowdsale-specific libraries in Chapter 9, Deep Dive into the OpenZeppelin Library.

There are many ERC20 and crowdsale-related libraries in the OpenZeppelin library package. Now, let's walk through how we can choose and use these libraries from the OpenZeppelin...
