Frequently Asked Questions
Get clear answers on how our Bitcoin Decentralized Identity Attestation SDK integrates with your project, from timelines and security to pricing and support.
For a standard integration with a single application, we typically see clients go live in 2-3 weeks. This includes initial setup, custom attestation logic development, and end-to-end testing. More complex deployments involving multiple systems or custom cryptographic schemes can take 4-6 weeks. We provide a detailed project plan during the discovery phase.
