Frequently Asked Questions
Get clear answers on how our real-time FX data and cross-chain settlement library accelerates your payment product development.
A standard integration for a single chain with core FX pairs (e.g., EUR/USD, GBP/USD) takes 2-3 weeks. Complex deployments supporting multiple chains (e.g., Ethereum, Polygon, Arbitrum) with custom settlement logic typically require 4-6 weeks. We provide a detailed project plan during the initial technical scoping call.
