The Move Book

Welcome to Move, a next-generation language for secure, sandboxed, and formally verified programming. It has been used as the smart contract language for several blockchains including Aptos. Move allows developers to write programs that flexibly manage and transfer assets, while providing the security and protections against attacks on those assets. However, Move has been developed with use cases in mind outside a blockchain context as well.

Move takes its cue from Rust by using resource types with move (hence the name) semantics as an explicit representation of digital assets, such as currency.

Who is the Aptos Move Book for?

Move was designed and created as a secure, verified, yet flexible programming language. The first use of Move was for the implementation of the Diem blockchain, and it is currently used on Aptos.

This book is suitable for developers with some programming experience and who want to begin understanding the core programming language and see examples of its usage.

Where Do I Start?

Begin by working through the Move Core Language Tutorial. The Primitive Types and Basic Concepts sections then walk through the language feature by feature, including modules and scripts. For an overview of what each release of the language adds, see Language Versions.
