Frequently Asked Questions
Get specific answers about our development process, security, and support for your payment gateway project.
A standard, production-ready Payment Oracle API Gateway deployment takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, off-chain relayers, API integration, and a full security audit. Complex multi-chain deployments or custom settlement logic may extend this to 6-8 weeks. We provide a detailed sprint-by-sprint timeline during the initial scoping call.
