Voice Authentication Development FAQs
Get clear answers on timelines, security, and process for implementing voice-based wallet authentication.
A standard implementation takes 2-4 weeks from kickoff to production. This includes integration of our SDK, custom voice model training, and on-chain smart contract deployment. Complex multi-chain deployments or custom biometric logic may extend this to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
