TANGIBLE RESULTS
Business Outcomes for Your Wallet Product
Integrating biometric authentication with CosmWasm delivers more than just a feature—it creates measurable advantages for your wallet's security, user base, and market position.
01
Enhanced Security Posture
We implement FIDO2/WebAuthn standards directly into your CosmWasm contracts, replacing seed phrases with hardware-backed biometrics. This reduces private key exposure risk and meets enterprise-grade security requirements.

Accelerated User Onboarding
Remove the friction of 12-24 word mnemonics. Our integration enables one-tap wallet creation and login via fingerprint or face ID, cutting sign-up time from minutes to seconds and boosting conversion rates.
