Frequently Asked Questions
Get clear answers about our StarkNet Cairo ZK-Proof Identity service for compliant, low-cost remittance.
Our system uses StarkNet's Cairo language to create zero-knowledge proofs that verify a user's identity credentials (like KYC/AML status) without revealing the underlying data. This allows a remittance platform to prove a sender is compliant to the network, enabling fast, low-fee transactions while maintaining user privacy and meeting regulatory requirements. We build the smart contracts and off-chain provers that handle this verification layer.
