A STRUCTURED APPROACH TO PRIVACY
Our Implementation Methodology
We deliver production-ready ZK-Rollup sandboxes through a proven, four-phase process designed for security, speed, and seamless integration.
01
Architecture & Design Sprint
We conduct a 1-week collaborative sprint to define your privacy requirements, select the optimal ZK framework (zkSync, StarkNet, Polygon zkEVM), and architect your custom sandbox environment.

Frequently Asked Questions
Get clear, technical answers about our privacy-preserving development and testing environment for ZK-Rollups.
From initial architecture to mainnet deployment, a standard ZK-Rollup with custom logic takes 6-10 weeks. The sandbox environment accelerates development, allowing for a functional testnet prototype in 2-3 weeks. Complex integrations (e.g., cross-chain bridges, custom privacy circuits) can extend the timeline.
