Frequently Asked Questions
Get clear answers on our ZK-Rollup circuit and smart contract development process, timelines, and security.
Our process follows a structured 4-phase methodology: 1. Discovery & Architecture (1-2 weeks): We define requirements, select the optimal ZK-SNARK/STARK framework (e.g., Circom, Halo2), and design the circuit architecture. 2. Core Development (3-6 weeks): Our team builds the custom zk-circuits and the on-chain verifier/manager contracts. 3. Audit & Testing (2-3 weeks): All code undergoes rigorous internal review, formal verification where applicable, and testing on a private testnet. 4. Deployment & Support (1 week): We assist with mainnet deployment and provide post-launch support. We provide weekly sprint demos and maintain a shared project dashboard.
