Frequently Asked Questions
Get clear answers on our wallet integration service, from timelines and security to pricing and support.
A standard integration for a single platform (e.g., web) typically takes 2-3 weeks. A full cross-platform deployment (Web, iOS, Android) with custom UI/UX usually completes in 4-6 weeks. Timeline depends on the number of target chains and required custom features like social login or multi-signature support.
