Frequently Asked Questions

Get clear answers on our process, security, and support for integrating stablecoin wallets and payment rails into your platform.

A standard integration for a single stablecoin (e.g., USDC on Ethereum) with core wallet features takes 2-4 weeks from kickoff to production deployment. Multi-chain support (e.g., adding Polygon, Arbitrum) or complex payment flow logic can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones during discovery.
