Frequently Asked Questions
Get clear answers on our process, security, and timelines for integrating seamless wallet solutions into your game.
A standard integration for 2-3 target chains takes 3-5 weeks from kickoff to production deployment. This includes architecture, core wallet SDK integration, chain-specific RPC/API connections, and comprehensive testing. Complex projects with custom token standards or 5+ chains may extend to 8-10 weeks. We provide a detailed sprint-by-sprint timeline in our initial proposal.
