PROVEN PROCESS
Our Development Methodology
Our systematic approach to ZK-Rollup privacy layer development ensures secure, scalable, and production-ready solutions. We deliver predictable outcomes with transparent communication at every stage.
01
Privacy Architecture Design
We design custom privacy layers using zk-SNARKs or zk-STARKs, selecting the optimal proving system (e.g., Plonk, Groth16) based on your throughput and trust assumptions. This ensures efficient proof generation and verification for your specific use case.

Circuit Development & Optimization
Our team writes and optimizes zero-knowledge circuits in Circom or Cairo, focusing on minimizing constraints and proof generation time. We implement custom privacy logic for transactions, identity, or data validation.

Frequently Asked Questions
Get clear answers on our development process, timelines, and security for your private rollup solution.
Our process follows a structured 4-phase methodology: 1. Discovery & Design (1-2 weeks): We analyze your use case, define privacy requirements, and architect the system. 2. Core Development (3-6 weeks): We build the custom circuits, smart contracts, and sequencer logic. 3. Testing & Audit (2-3 weeks): Rigorous internal testing followed by a third-party audit from firms like Spearbit or Zellic. 4. Deployment & Support (1 week): We deploy to your chosen testnet/mainnet and provide 90 days of post-launch support. We provide weekly demos and maintain full transparency via a shared project dashboard.
