Frequently Asked Questions
Get specific answers about our development process, security, and timelines for your private payment solution.
A standard deployment, including a custom smart contract suite and integration with your frontend, typically takes 3-5 weeks. This includes 1 week for architecture design, 2-3 weeks for core development and internal testing, and 1 week for integration and deployment. Complex requirements like custom compliance modules or multi-chain support can extend this timeline, which we scope and quote for upfront.
