Common Questions on SDK Development
Answers to the most frequent questions from CTOs and product leads evaluating a mobile payment SDK partner.
Standard SDK integration takes 2-4 weeks from kickoff to production. This includes core wallet connection, payment flow, and initial testing. Complex features like multi-chain swaps or custom UI/UX can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones during scoping.
