ZK-Rollup Privacy Key Infrastructure Development | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built by engineers who have deployed over $1B+ in on-chain value.

We architect and deploy production-grade smart contracts that power your core business logic. Our team specializes in Solidity 0.8+ and Vyper, leveraging battle-tested libraries like OpenZeppelin and implementing advanced patterns for gas optimization and upgradeability via Transparent or UUPS proxies.

Security-First Development: Every contract undergoes rigorous internal review and formal verification before submission to top-tier auditors like CertiK or Trail of Bits.
Full Lifecycle Support: From initial architecture and Hardhat/Foundry testing suites to mainnet deployment and post-launch monitoring.
Protocol Specialization: Custom implementations for ERC-20, ERC-721, ERC-1155, staking systems, multi-signature wallets, and bespoke DeFi primitives.

We deliver audited, gas-optimized contracts in 2-4 weeks, enabling you to launch with confidence and mitigate catastrophic financial risk.

ZK-PKI ENGINEERING

Core Technical Capabilities We Deliver

We architect and deploy production-ready Zero-Knowledge Privacy Key Infrastructure, delivering cryptographic guarantees and enterprise-grade reliability for your Web3 applications.

Custom ZK Circuit Design

We design and implement custom zk-SNARK and zk-STARK circuits for your specific privacy logic, using Circom, Halo2, and Plonky2. This enables selective data disclosure and confidential transactions without compromising on-chain verifiability.

Key Management & Custody

Secure, auditable key generation, storage, and lifecycle management for ZK proof signing keys. Our solutions include MPC (Multi-Party Computation) setups, HSM integration, and automated rotation policies to eliminate single points of failure.

Rollup Integration & Proving

Seamless integration of your ZK-PKI layer with leading rollup frameworks like Starknet, zkSync Era, and Polygon zkEVM. We handle the full proving pipeline, from witness generation to on-chain verification, ensuring data availability and finality.

Security Audits & Formal Verification

Our ZK systems undergo rigorous security audits by firms like Trail of Bits and Quantstamp, supplemented by in-house formal verification of circuit logic using tools like Picus and VeriSolid to eliminate cryptographic vulnerabilities.

Gas-Optimized Verifier Contracts

Deployment of highly gas-optimized Solidity verifier smart contracts for your custom circuits. We reduce on-chain verification costs by up to 40% using techniques like batch verification and optimal field arithmetic.

Monitoring & Alerting Dashboard

A dedicated observability dashboard providing real-time metrics on proof generation success rates, latency, key health, and system uptime. Get instant alerts for anomalies to maintain 99.9% SLA for your privacy layer.

DELIVERABLES

Business Outcomes for Your Product

Our ZK-Rollup Privacy Key Infrastructure delivers measurable results for your application, from enhanced security to accelerated time-to-market.

Zero-Knowledge Identity Verification

Implement private user authentication and KYC/AML compliance without exposing sensitive data. Users prove eligibility without revealing personal information, enabling regulatory compliance with user privacy.

Private Transaction Signing

Enable users to sign transactions with keys secured within a ZK-Rollup. Signatures are generated off-chain with cryptographic proofs, keeping wallet addresses and transaction patterns private on the mainnet.

Reduced On-Chain Gas Costs

Batch thousands of private key operations into a single ZK proof submitted to L1. Drastically lower the gas fees associated with secure, verifiable authentication and signing for your user base.

Enterprise-Grade Security Audit

Receive a deployment backed by formal verification and audits from leading security firms. Our infrastructure uses battle-tested cryptographic libraries and undergoes regular penetration testing.

Rapid Integration & Deployment

Leverage our SDKs and APIs to integrate ZK privacy features in weeks, not months. We provide full documentation, developer support, and a staging environment for seamless testing.

Scalable User Onboarding

Support millions of users with a horizontally scalable key management layer. Our architecture ensures low-latency proof generation and verification as your application grows.

Frequently Asked Questions

Get clear answers about our specialized service for building secure, scalable private key management for ZK-Rollups.

ZK-Rollup Privacy Key Infrastructure is a specialized system for generating, storing, and managing the private keys that sign zero-knowledge proofs and authorize state transitions on your rollup. You need it to ensure the security and liveness of your chain. A compromised key can halt the network or allow fraudulent state updates. Our PKI provides enterprise-grade key management with hardware security modules (HSMs), multi-party computation (MPC), and automated key rotation, eliminating single points of failure.
