overview
CORE INFRASTRUCTURE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Security Audits: Every contract undergoes rigorous review using
SlitherandMythril, followed by a formal audit report. - Gas Efficiency: Optimized for cost, achieving up to 40% lower transaction fees on EVM chains.
- Compliance Ready: Built-in patterns for
ERC-20,ERC-721, andERC-1155with upgradeability viaTransparent ProxyorUUPS. - Full Lifecycle: From initial spec to deployment on
Mainnet,Arbitrum, orPolygon, including verification and monitoring setup.
We deliver battle-tested contracts that reduce your time-to-market by weeks and mitigate critical vulnerabilities before they reach production.

PROVEN PROCESS
Our 4-Phase Migration Methodology
A systematic, low-risk approach to migrating your dApp or protocol from L1 or other L2s to a custom ZK-Rollup. We de-risk your transition with clear deliverables at every phase.
01
Phase 1: Architecture & Feasibility
We conduct a comprehensive audit of your existing smart contracts and application logic to design an optimal ZK-Rollup architecture. This phase delivers a detailed migration blueprint, gas cost analysis, and a go/no-go recommendation.

Technical & Commercial Questions
ZK-Rollup Migration FAQs
Answers to the most common questions from CTOs and technical leads evaluating ZK-Rollup migration partners. Based on our experience delivering 30+ production rollups securing over $1.2B in TVL.
A standard ZK-Rollup migration for a DeFi protocol takes 6-10 weeks. This includes 2 weeks for architecture & design, 3-5 weeks for core development and integration, and 1-2 weeks for security audits and final deployment. Complex applications with custom circuits or multi-chain logic may extend to 12-14 weeks. We provide a detailed, phase-gated project plan during the initial technical assessment.
