DELIVERABLES & METRICS
Business Outcomes for Your Product
Our biometric Web3 login development delivers measurable improvements in user acquisition, security, and operational efficiency. Here are the concrete outcomes you can expect.
01
Frictionless User Onboarding
Replace seed phrases and password managers with face or fingerprint authentication. We deliver a seamless login flow that reduces new user activation time from minutes to seconds, directly increasing conversion rates.
< 10 seconds
First-time login
40%+
Higher activation
02
Enterprise-Grade Security
Implement FIDO2/WebAuthn standards with on-device biometric storage. We build systems where private keys never leave the user's secure enclave, eliminating phishing and credential theft vectors common in Web2.

Frequently Asked Questions
Common questions from CTOs and product leads about integrating secure, user-friendly biometric authentication.
A standard integration takes 2-4 weeks from kickoff to production deployment. This includes requirements analysis, SDK integration, custom UI/UX development, smart contract deployment, and security review. Complex multi-chain or custom biometric modalities can extend the timeline, which we scope and quote upfront.
