Frequently Asked Questions
Get clear answers on how our interchain KYC verification service works, from integration to ongoing support.
A standard integration takes 2-4 weeks from kickoff to production deployment. This includes smart contract development, integration with your dApp's frontend, and a full security audit. For complex multi-chain deployments or custom compliance rules, the timeline may extend to 6-8 weeks. We provide a detailed project plan within the first 3 business days.
