Your Technical Questions, Answered
Blockchain Migration FAQs for NeoBank Leaders
Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating a blockchain migration partner.
Our standard migration process takes 4-8 weeks from kickoff to mainnet deployment. This includes 1-2 weeks for architecture review and planning, 2-4 weeks for core development and testing, and 1-2 weeks for security audits and final deployment. For complex, multi-chain neobank architectures with custom DeFi modules, timelines may extend to 12 weeks. We provide a detailed, phase-gated project plan in our initial proposal.
