Frequently Asked Questions

Get clear answers about our specialized service for building secure, interoperable identity bridges on Polkadot.

A Polkadot Parachain Identity Bridge is a custom-built, cross-chain messaging module that securely transfers verifiable identity credentials (like KYC status, reputation scores, or access tokens) between a parachain and an external blockchain (e.g., Ethereum, Polygon). You need one to unlock new user bases, enable seamless multi-chain dApps, and leverage identity data from other ecosystems without rebuilding your KYC/AML stack, reducing development time by 6-12 months.
