Preface

Rust is one of the most widely used languages in blockchain systems and many popular blockchains including Solana, Polkadot, Aptos, and Sui are built with Rust. Rust frameworks such as Foundry are also highly preferred by developers of established chains including Ethereum.

Learning how decentralized apps work on popular Rust chains and also how to build your own blockchains – whether from scratch or using frameworks such as Substrate – is an important skill to have since all big dApps, at some point, end up moving to their own chains, also referred to as application chains.

This book is for developers who want to go deep and understand how Rust is used for building dApps and blockchains and add a new dimension to their Rust skills.
