Frequently Asked Questions
Get clear answers on how we modernize your legacy payment infrastructure with secure, real-time Bitcoin settlement.
A standard integration for a single legacy system takes 2-4 weeks from kickoff to production deployment. This includes discovery, custom gateway development, testing, and go-live support. Complex multi-system integrations or custom hardware requirements can extend this to 6-8 weeks. We provide a detailed project plan with milestones during the initial consultation.
