- The Solidity linters do report some security issues at the Solidity level. They also help in finding common security issues.
- No, having 100% contract coverage does not mean that testing is done efficiently. It only suggests that all the possible branches have been covered by the test cases. However, there could be more test scenarios that are not covered by the test cases; they must be included in the test suite by the developers.
- When you are trying to debug and find out the internal function traces of a specific function, function traces should be used. This will help you understand the transaction flow in the case of complex contract structures.
- It is good practice to use the Solidity linters for projects. The linters find the common issues that would improve your code quality, and sometimes also report common security issues.

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.
