METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to building and deploying privacy-preserving payment protocols that scale. We deliver production-ready systems, not just prototypes.
01
1. Protocol Design & Architecture
We architect your payment protocol using Zero-Knowledge Proofs (zk-SNARKs/STARKs) or confidential assets, ensuring regulatory compliance (e.g., FATF Travel Rule) and optimal gas efficiency from day one.

Frequently Asked Questions
Get clear, technical answers on how we build secure, compliant, and scalable private payment systems.
For a core protocol with standard features (private transfers, shielded pools, basic compliance hooks), development and audit typically takes 8-12 weeks. Complex deployments with custom compliance logic, multi-chain support, or novel cryptographic primitives can extend to 16-20 weeks. We provide a detailed project plan with milestones after the initial discovery phase.
