Solidity 0.8+orRustusingOpenZeppelinlibraries and battle-tested patterns. - Comprehensive Audits: Every contract undergoes internal review and optional third-party audits from firms like
CertiKorQuantstamp. - Gas Optimization: We minimize transaction costs, targeting up to 40% gas reduction versus unoptimized implementations.
- Full Deployment Suite: We handle everything from local testing to mainnet deployment with
Hardhat/FoundryorAnchor.
We don't just write code; we deliver audited, gas-efficient contracts that form the secure backbone of your Web3 application.
Technical & Commercial Details
ZK-Rollup Data Availability FAQs
Get clear, expert answers to the most common questions about building and deploying a custom ZK-Rollup Data Availability (DA) layer with Chainscore Labs.
A production-ready ZK-Rollup Data Availability layer typically deploys in 4-8 weeks from kickoff. This includes architecture design, smart contract development, integration with your chosen proving system (e.g., zkSync, StarkEx, Polygon zkEVM), and comprehensive security audits. The timeline varies based on complexity: a standard Celestia/EigenDA integration can be faster, while a custom validity proof scheme with novel data sharding will take longer. We provide a detailed project plan within the first week of engagement.
