Frequently Asked Questions
Get clear answers on implementation, security, and support for our SDK that enables trustless mobile dApps.
A standard integration takes 2-3 weeks from kickoff to production deployment. This includes environment setup, core feature implementation (like state verification), and a security review. Complex customizations or multi-chain support can extend this timeline, which we scope during the initial technical discovery call.
