> TOOLCHAIN FOR PROVABLE APPLICATIONS

Dojo helps developers build provable games and applications on Starknet by providing a toolkit and framework for onchain development.

Dojo is a toolchain designed for building provable games and applications. It extends Cairo, allowing developers to create applications that are natively composable, extensible, permissionless, and persistent. The framework reduces complexity in developing provable applications that can be deployed to and verified by blockchains, particularly Starknet.
