Frequently Asked Questions
Get clear, technical answers about integrating hardware-grade security into your mobile dApp. Based on 30+ successful integrations for DeFi, NFT, and institutional platforms.
A standard integration with a single hardware vendor (e.g., Ledger, Keystone) takes 3-5 weeks from kickoff to production deployment. This includes architecture review, SDK integration, secure transaction flow implementation, and QA testing. Multi-vendor support or complex DeFi protocol integrations can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones.
