The Cairo Book

By the Cairo Community and its contributors. Special thanks to StarkWare through OnlyDust, and Voyager for supporting the creation of this book.

This version of the text assumes you’re using the Cairo Compiler version 2.8.3 and Starknet Foundry version 0.31.0. See the Installation section of Chapter 1 to install or update Cairo and Starknet Foundry.

If you want to play around with Cairo code and see how it compiles into Sierra (Intermediate Representation) and CASM (Cairo Assembly), you can use cairovm.codes playground.
