Frequently Asked Questions
Get clear answers on our process, security, and outcomes for integrating biometric authentication into your EVM wallet.
Standard integrations take 2-4 weeks from kickoff to production deployment. This includes architecture review, secure key management implementation, biometric SDK integration (Face ID/Touch ID, Android BiometricPrompt), and rigorous security testing. Complex requirements like multi-chain support or custom UI/UX can extend the timeline, which we scope and agree upon upfront.
