Hardware Wallet Integration FAQs
Get specific answers to the most common questions CTOs and product leads ask when evaluating a Hardware Wallet as a Service (WaaS) provider.
A standard integration for a single protocol (e.g., EVM-based DApp) takes 2-4 weeks from kickoff to production deployment. Complex multi-chain integrations or custom transaction flows may extend this to 6-8 weeks. We provide a detailed project plan with milestones during the initial scoping call.
