Frequently Asked Questions
Get specific answers about our SDK development process, security, and support.
A standard POS wallet SDK integration takes 3-5 weeks from kickoff to production-ready delivery. This includes core wallet features (key management, transaction signing), POS-specific modules (QR scanning, NFC tap-to-pay), and merchant dashboard integration. Complex requirements like multi-chain support or custom loyalty programs may extend the timeline, which we outline in a detailed project plan before engagement.
