Frequently Asked Questions
Get clear answers on our development process, timelines, security, and support for your EVM-based identity wallet project.
A production-ready MVP for an EVM-based mobile identity wallet typically takes 6-10 weeks. This includes core features like MPC/SSI key management, a user-friendly interface, and integration with 2-3 target EVM chains. Complex integrations (e.g., custom biometrics, multi-protocol DeFi dashboards) can extend the timeline. We provide a detailed project plan with weekly milestones from day one.
