Discover the advanced features of Solidity that will help you write high-quality code and develop secure smart contracts with the latest ERC standards
Delve into Solidity and understand control structures, function calls, and variable scopes
Explore tools for developing, testing, and debugging your blockchain applications
Learn advanced design patterns and best practices for writing secure smart contracts
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.
What you will learn
Test and debug smart contracts with Truffle, Ganache, Remix, and MetaMask
Gain insights into maintaining code quality with different tools
Get up to speed with ERC standards such as ERC-20 and ERC-721
