PREDICTABLE, AUDITABLE, SCALABLE
Our Proven Delivery Methodology
Our systematic approach to building with validity proofs ensures predictable costs, auditable progress, and scalable outcomes—giving your team complete financial clarity from day one.
01
Phase 1: Architecture & Proof Design
We design a custom validity proof architecture (zk-SNARKs, zk-STARKs) tailored to your use case, defining the precise computational statements to be proven. This upfront clarity prevents scope creep and establishes the fixed-cost baseline for your project.
