PROVEN PROCESS
Our Delivery Methodology
Our structured, four-phase approach ensures your encrypted mempool is delivered on time, on budget, and to the highest security standards. We focus on measurable outcomes, not just features.
01
Architecture & Threat Modeling
We begin with a comprehensive security-first design, analyzing your specific use case to model threats and define the optimal encryption scheme (e.g., ZK-SNARKs, FHE, or secure enclaves). This phase establishes the technical blueprint and security guarantees.
