About Cairo Programming Language

 

Cairo is a Rust-inspired programming language designed for building scalable decentralised applications using validity proofs. 

 

As the native language of Starknet, Cairo enables developers to create STARK-provable smart contracts efficiently. 

 

Starknet is a permissionless decentralised zkRollup that utilises zk-STARKs technology to achieve scalability. As a Layer 2 (L2) solution for Ethereum, Starknet aims to provide fast, secure, and low-cost transactions. 

 

The latest version, Cairo v2.6.0, was released in March 2024, bringing new enhancements and features to the language. 

The Hashlock Security Rating System

Our Blockchain audits are based on our consistent rating system, in which code is qualified based on its quality, vulnerability, future risk, and complexity. We advise that projects with a rating less than secure should not be deployed, and the Hashlocked rating is reserved for projects that value and invest in ongoing security efforts after the audit to protect their stakeholders.
