Frequently Asked Questions
Get clear answers on our framework's capabilities, security, and implementation process.
A standard deployment for a custom cross-chain messaging and asset bridge takes 4-6 weeks from kickoff to mainnet launch. This includes design, development, security audits, and deployment. More complex systems with custom consensus or multi-chain governance can extend to 8-10 weeks. We provide a detailed project plan with milestones in the first week.
