ENTERPRISE-GRADE SECURITY
Core Capabilities of Our Biometric Pallet
Our Substrate-native biometric pallet delivers production-ready, secure identity verification for your Polkadot parachain wallet. We handle the cryptographic complexity so you can focus on user experience and compliance.
01
On-Chain Biometric Verification
Integrate fingerprint, face, or iris recognition directly into your wallet's transaction signing flow. Our pallet securely processes biometric data on-device, generating a zero-knowledge proof for on-chain verification without exposing raw data.
