Frequently Asked Questions
Get clear answers on implementation timelines, security, and support for your cross-chain payment system.
For a standard cross-chain payment system connecting 2-3 major chains (e.g., Ethereum, Polygon, Arbitrum), we deliver a production-ready MVP in 4-6 weeks. Complex deployments with 5+ chains, custom bridging logic, or advanced features like gas abstraction may take 8-12 weeks. We follow a phased approach: Discovery & Design (1 week), Core Development & Smart Contracts (2-4 weeks), Integration & Testing (1-2 weeks), and Security Audit (1 week).
