Frequently Asked Questions
Get answers to common technical and commercial questions about building secure, scalable cross-chain data availability layers.
A standard implementation for a production-ready cross-chain data availability layer takes 4-8 weeks. This includes design, core development, integration with your existing stack, and initial testing. Complex multi-chain ecosystems or novel consensus mechanisms can extend this to 12+ weeks. We provide a detailed project plan with milestones within the first week of engagement.
