StarkNet Cairo Compliance Verifier Development
We engineer custom Cairo-based verifiers for StarkNet ZK-Rollups. Our verifiers cryptographically prove transaction compliance (e.g., accredited investor status, jurisdiction) within a validity proof, enabling private, on-chain regulatory checks for institutional DeFi.

Technical & Commercial Details
Frequently Asked Questions on Compliance Verifiers
Get clear answers on our StarkNet Cairo compliance verifier development process, timelines, security, and support.
A compliance verifier is a zero-knowledge proof circuit that validates on-chain transactions against a predefined rulebook (e.g., sanctions lists, jurisdictional limits, KYC status). On StarkNet, written in Cairo, it enables automated, trustless, and private compliance for DeFi protocols, exchanges, and institutional platforms. It moves compliance logic from centralized servers to the validity layer, ensuring rules are enforced without exposing sensitive user data, reducing operational risk, and enabling global scale.
