Frequently Asked Questions
Answers to common technical and commercial questions about our specialized bridge development services.
For a standard, production-ready bridge connecting two ecosystems (e.g., Ethereum to a custom AppChain), the typical timeline is 6-10 weeks. This includes architecture, core development, security audits, and deployment. More complex multi-chain connectors or those requiring novel consensus mechanisms can take 12-16 weeks. We provide a detailed project plan with milestones within the first week of engagement.
