PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to deliver a production-ready ZK payment gateway in weeks, not months. We focus on rapid integration and enterprise-grade reliability.
01
Discovery & Architecture Design
We analyze your payment flows and design a custom ZK circuit architecture. This phase defines the cryptographic proofs, token standards (ERC-20, ERC-4337), and integration points for your mobile app.

Frequently Asked Questions
Get clear, technical answers about our Zero-Knowledge Mobile Payment Gateway development and deployment process.
A production-ready gateway with core features (wallet integration, ZK proofs for privacy, fiat on/off-ramps) typically deploys in 6-10 weeks. This includes 2 weeks for architecture and design, 3-5 weeks for core development and smart contract auditing, and 1-2 weeks for integration and testing. Complex features like multi-chain support or custom compliance logic can extend the timeline, which we scope and agree upon upfront.
