Frequently Asked Questions
Get clear answers on our specialized audit process for Cairo smart contracts, designed for CTOs and technical founders.
Cairo License Verification is a specialized audit process for StarkNet smart contracts written in Cairo. It's critical because Cairo's unique architecture (e.g., the Cairo VM, hint system, and storage model) introduces novel security risks not found in EVM-based chains. Our verification ensures your contract logic is sound, your code is free from Cairo-specific vulnerabilities, and it adheres to the intended license and access control rules, protecting your protocol's assets and users.
