CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
Deliver a secure, auditable, and gas-optimized foundation for your Web3 product in as little as 2-4 weeks.
- Full-Stack Development: From
ERC-20/ERC-721tokens to complex DeFi logic, cross-chain bridges, and DAO governance systems. - Security & Audits: Built with OpenZeppelin standards, followed by rigorous internal review and preparation for third-party audits (e.g., CertiK, Quantstamp).
- Gas Optimization: Every contract is optimized for lower transaction costs and higher throughput on mainnet.
- Compliance Ready: Architecture designed with regulatory considerations in mind, including upgradeability patterns and admin controls.

DELIVERABLES
Business Outcomes for Your ZK-Rollup
Our encrypted data availability service provides the critical infrastructure layer for your rollup, delivering measurable results for your engineering and business teams.
01
Guaranteed Data Availability
We ensure your ZK-rollup's transaction data is always accessible for verification, preventing fraud and enabling trustless withdrawals. This eliminates the single point of failure of centralized sequencers.

Uptime SLA
7 Days
Data Retention
02
Enhanced Security & Privacy
Data is encrypted at rest and in transit using industry-standard AES-256-GCM. This protects sensitive transaction details from front-running and MEV bots before batch finalization on L1.

Frequently Asked Questions on Encrypted Data Availability
Get clear, specific answers on how Chainscore Labs delivers secure, scalable, and cost-effective encrypted data availability for your ZK-Rollup.
We provide a modular, API-first integration. Our service delivers a custom Data Availability (DA) smart contract and a set of off-chain relayers. You integrate by pointing your sequencer's data submission to our API endpoint. We handle encryption, storage, and retrieval proofs. Typical integration requires modifying 50-100 lines of your existing rollup contract code and takes 1-2 developer days for our team to assist with.
