The cost to develop a crypto payment gateway is highly variable, generally ranging from $10,000 to over $30,000 depending on the development path: a quick, cost-effective launch using a white-label solution typically falls in the lower end, while a fully custom, enterprise-grade system with complex features like multi-chain support, instant fiat conversion, and robust KYC/AML compliance demands a budget exceeding $50,000. Key cost drivers include the number of supported cryptocurrencies and blockchain integrations, the need for advanced security audits, the integration of third-party financial APIs for real-time off-ramping, and the geographic location and hourly rates of the development team; furthermore, businesses must account for ongoing maintenance, infrastructure fees, and crucial regulatory and legal compliance costs beyond the initial build.
