Card Network API Bridge
Frequently Asked Questions
Common questions from CTOs and product leads about integrating traditional card networks with blockchain via our API bridge.
Standard deployments take 2-4 weeks from kickoff to production-ready integration. This includes design, development, testing, and deployment of the core bridge infrastructure. Complex multi-chain or custom settlement logic can extend this to 6-8 weeks. We provide a detailed project plan within the first 48 hours of engagement.
