PREDICTABLE & TRANSPARENT
Our Delivery Process
A structured, four-phase methodology designed for technical leaders. We deliver fully integrated ZK-Rollup upgrades with clear milestones, zero surprises, and guaranteed outcomes.
01
Phase 1: Architecture & Audit
We conduct a comprehensive audit of your existing dApp and L1 contracts, then design a custom ZK-Rollup integration blueprint. This includes selecting the optimal proof system (zkSync, StarkNet, Polygon zkEVM) and defining the data availability layer.

Technical & Commercial Details
ZK-Rollup Upgrade Integration FAQs
Get clear answers to the most common questions CTOs and technical leads ask when evaluating a ZK-Rollup upgrade partner. We focus on timelines, security, and measurable outcomes.
A standard upgrade from an existing L1 or optimistic rollup to a ZK-Rollup takes 4-8 weeks from kickoff to mainnet deployment. This includes 1-2 weeks for architecture review, 2-4 weeks for core development and integration, and 1-2 weeks for testing, security review, and deployment. Complex protocols with custom circuits or novel state transitions may extend this timeline, which we define in a fixed-scope proposal.
