PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to delivering production-ready cross-chain ZK fraud proof systems. We focus on rapid integration, verifiable security, and measurable outcomes.
01
Architecture & Threat Modeling
We begin with a comprehensive analysis of your cross-chain data flows and threat vectors. This phase defines the security perimeter, selects optimal ZK proving systems (e.g., zk-SNARKs, zk-STARKs), and establishes the fraud proof logic to protect your bridge or rollup.

02
Circuit Development & Optimization
Our engineers write and optimize the zero-knowledge circuits (using Circom, Halo2, or Cairo) that form the core of your fraud proof system. We prioritize gas efficiency for on-chain verification and minimal proving times for off-chain computation.
