Frequently Asked Questions
Get clear answers on integrating secure, seamless biometric authentication into your Web3 gaming wallet.
A standard integration with a single biometric modality (e.g., Face ID) takes 2-3 weeks from kickoff to production deployment. Multi-modal integrations (Face ID + fingerprint + passkeys) or complex game-specific logic can extend this to 4-6 weeks. We provide a detailed sprint plan upfront.
