Secure, audited smart contracts built to your exact specifications and deployed on-chain.
We architect and deploy production-ready smart contracts for tokens, DeFi protocols, NFTs, and DAOs. Our development process ensures gas optimization, security-first design, and compliance with standards like ERC-20, ERC-721, and ERC-1155.
Deploy a custom, audited contract suite in as little as 2-4 weeks.
Solidity 0.8+ development to deployment and on-chain verification.We build production-ready ZK-rollup identity layers with battle-tested components, ensuring security, scalability, and seamless integration for your FinTech or Web3 application.
Custom-built zero-knowledge circuits for identity attestations (KYC, credentials, reputation) that generate succinct proofs, preserving user privacy while enabling on-chain verification.
Gas-optimized Solidity verifiers deployed on your target L1 (Ethereum, Arbitrum, etc.) with sub-100k gas costs per proof verification, ensuring low operational expenses.
A resilient, decentralized network for ordering transactions and generating ZK proofs, providing censorship resistance and 99.9% uptime for your rollup's liveness.
Secure, non-custodial bridges (using LayerZero or Axelar) to port verified identity states across EVM and non-EVM chains, enabling a unified identity layer.
Integration with EigenDA or Celestia for secure, cost-effective off-chain data storage of identity transaction data, ensuring data availability without compromising privacy.
Comprehensive TypeScript/Go SDKs and REST APIs for easy integration, allowing your team to issue credentials, verify proofs, and manage the rollup in < 2 weeks.
Our ZK-Rollup Identity Layer development delivers concrete, measurable results that accelerate your product roadmap and build user trust.

A structured, security-first methodology to deliver a production-ready ZK-rollup identity layer in 8-12 weeks, from initial design to mainnet launch.
We design a custom ZK-rollup architecture (zkEVM, zkSync, StarkEx) tailored to your identity use case. This includes defining the state transition logic, data availability strategy, and sequencer/prover infrastructure for optimal performance and cost.
Our team builds the core zero-knowledge circuits (Circom, Halo2) for identity proofs and the L1/L2 smart contracts for rollup management. All code follows OpenZeppelin standards and is optimized for gas efficiency and security.
Every component undergoes rigorous internal review followed by an external audit from a top-tier firm like Trail of Bits or Quantstamp. Critical circuits are formally verified to eliminate logical flaws before deployment.
We deploy the complete stack to a public testnet (Sepolia, Holesky, zkSync Sepolia) and conduct end-to-end integration testing. This includes stress testing the prover, validator nodes, and frontend SDKs under realistic load.
We manage the mainnet deployment, including contract verification, initial sequencer/prover setup, and monitoring dashboard configuration. We provide full documentation and training for your team to assume operational control.
Post-launch, we offer SLA-backed maintenance packages covering node operation, performance optimization, security patches, and protocol upgrades (EIPs, hard forks). We ensure your layer remains secure and up-to-date.
A detailed comparison of the cost, time, and risk profile for developing a custom ZK-Rollup identity layer in-house versus partnering with Chainscore Labs for a dedicated, production-ready solution.

Custom Privacy & Compliance Logic | Full flexibility | Limited by platform constraints | Fully customizable to spec |
Ongoing Node Operation & Maintenance | Your DevOps team (2+ FTEs) | Managed by platform (shared) | Fully managed by Chainscore SLA |
Annual Operational Cost (Year 1) | $250K+ (team + infra) | $60K - $120K (platform fees) | $40K - $100K (managed service) |
Settlement Finality & Throughput | Customizable (Target: <2 sec) | Platform-dependent (Variable) | Guaranteed (<2 sec, 10k+ TPS) |
Integration with Existing KYC/AML Stack | Custom development required | Limited pre-built adapters | Pre-built adapters + custom connectors |
Exit Strategy & Data Portability | Full control | Vendor lock-in risk | Full sovereignty & data portability |
Answers to the most common questions CTOs and founders ask when evaluating a custom ZK-rollup identity layer development partner.
Our standard engagement follows a 6-8 week delivery cycle for a production-ready ZK-rollup identity layer. We use a phased approach: Week 1-2 for architecture & smart contract design, Week 3-5 for core development and integration with your dApp, and Week 6-8 for security audits, testing, and mainnet deployment. For complex integrations (e.g., cross-chain identity), timelines extend to 10-12 weeks. We provide weekly sprint demos and maintain a shared Jira/GitHub project for full transparency.
