Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for your payment gateway project.
A standard, production-ready NEAR merchant gateway with core features (wallet integration, payment processing, admin dashboard) typically deploys in 2-4 weeks. Complex integrations with existing ERP/CRM systems or custom multi-chain features can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint timeline after the initial technical discovery phase.
