Frequently Asked Questions
Get clear answers on how we deliver secure, auditable, and scalable compliance layers for your StarkNet applications.
A ZK-Rollup compliance layer is a smart contract system built on top of StarkNet that enforces regulatory and business logic (like KYC/AML, transaction limits, jurisdiction rules) using zero-knowledge proofs. You need one to operate in regulated markets, partner with traditional finance, or implement complex gated access while preserving user privacy and maintaining StarkNet's scalability. We've built layers securing over $200M in TVL for DeFi and gaming protocols.
