- Ethereum is a public blockchain, hence all account addresses and transaction data are visible to everyone. There has been some research going on regarding the use of zk-SNARK (zero-knowledge succinct non-interactive argument of knowledge) to perform private transactions on the Ethereum blockchain.
- The delegatecall function should not be used at first. If it is required, then it should be used with extra care to ensure that delegatecall does not allow unauthorized code execution.
- To prevent your contracts from re-entrancy attacks, you must ensure that the state variables are updated before sending ether using the <address>.transfer() function. In other words, the transfer function should be called at the last step in the function.
- The Solidity language uses the intX and uintX data types. Both of these data types are prone to integer overflow...

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.
