We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our focus is on security-first development, utilizing audited libraries like OpenZeppelin and implementing gas-optimized patterns.
Privacy-Preserving State Synchronization
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Lifecycle Support: From initial design and
Solidity/Rustdevelopment to deployment, verification, and ongoing maintenance. - Comprehensive Audits: Every contract undergoes internal review and is prepared for third-party audits from firms like
CertiKorQuantstamp. - Key Deliverables:
ERC-20,ERC-721,ERC-1155tokens, DeFi protocols (DEX/AMM, staking), NFT marketplaces, and custom business logic.
Deliver a secure, auditable foundation for your Web3 product, reducing time-to-market and mitigating critical vulnerabilities.
Core Technical Capabilities We Deliver
We build production-ready, audited privacy infrastructure that scales. Our engineering team delivers battle-tested solutions with clear SLAs, not just theoretical concepts.
Zero-Knowledge Proof Integration
Design and implement custom zk-SNARKs and zk-STARKs circuits for private state transitions. We handle the full stack from circuit design in Circom/Halo2 to on-chain verifier deployment, ensuring optimal gas costs and proof generation times.
Secure Multi-Party Computation (MPC) Networks
Deploy robust MPC protocols for threshold signatures and distributed key generation. Our architecture ensures no single party can compromise user privacy, with nodes distributed across trusted, compliant entities.
Encrypted State Management
Engineer systems for homomorphic encryption and secure enclave (TEE) operations to process data without decryption. We implement best practices for key lifecycle management and data-in-use protection.
Regulatory-Compliant Design
Architect systems with selective disclosure and auditability features built-in. We implement privacy-preserving KYC/AML rails and transaction monitoring that satisfy regulatory requirements without breaking user anonymity.
Performance-Optimized Relayers
Develop high-throughput relay services with sub-second latency for submitting private transactions. Our infrastructure is load-balanced, auto-scaling, and monitored 24/7 to handle enterprise-grade volume.
Business Outcomes for Your Project
Our Privacy-Preserving State Synchronization service delivers measurable improvements to your application's security, performance, and compliance posture.
Regulatory Compliance by Design
Deploy applications that meet GDPR, MiCA, and other data privacy regulations by default. Our zero-knowledge proofs and selective disclosure mechanisms ensure user data is never exposed on-chain, eliminating compliance risk.
Enhanced User Trust & Adoption
Gain a competitive edge by offering users true data sovereignty. By proving state transitions without revealing sensitive inputs, you build applications users trust with their financial and personal data, driving higher engagement and retention.
Enterprise-Grade Security Posture
Integrate with confidence. Our architecture is built on audited ZK circuits (e.g., Circom, Halo2) and secure multi-party computation (MPC) protocols, providing cryptographic guarantees that sensitive business logic and user states remain confidential.
Scalable, Cost-Effective Architecture
Reduce on-chain gas costs by up to 90% by moving complex state logic off-chain. Our system batches and proves state transitions, submitting only a single cryptographic proof to the blockchain, optimizing for both L1 and L2 networks.
Faster Time-to-Market
Accelerate development with our production-ready SDKs and APIs. We provide the complex privacy infrastructure, so your team can focus on application logic. Go from concept to mainnet in weeks, not months.
Future-Proof Interoperability
Synchronize private state across EVM chains (Ethereum, Polygon, Arbitrum) and non-EVM environments. Our protocol-agnostic design ensures your application isn't locked into a single blockchain, protecting your long-term infrastructure investment.
Build vs. Buy: Implementing Private State Sync
A detailed comparison of the total cost, risk, and time investment required to build a privacy-preserving state synchronization system in-house versus partnering with Chainscore.

Annual Maintenance & Ops | $150K - $300K | Optional SLA from $50K |
Security & Audit Burden | High (custom, unaudited code) | Low (pre-audited, battle-tested modules) |
Team Expertise Required | Specialized cryptography & ZK engineers | Your existing Web3 devs |
Protocol Flexibility | Locked to initial design | Modular, upgradeable architecture |
Time to First Valid Proof | Months of R&D | Days to weeks |

Our Development & Integration Process
A structured, four-phase approach designed for enterprise-grade security and rapid deployment. We manage the technical complexity so you can focus on your product roadmap.
Phase 1: Architecture & Threat Modeling
We design your privacy-preserving sync architecture, selecting optimal ZK frameworks (e.g., zk-SNARKs via Circom, zk-STARKs) and defining data flow. Includes a formal threat model to identify and mitigate risks before a single line of code is written.
Phase 2: Core Protocol Development
Implementation of the zero-knowledge proof circuits and state synchronization logic. We deliver production-ready, auditable code with comprehensive unit and integration tests, ensuring correctness and gas efficiency.
Phase 3: Security Audit & Formal Verification
Rigorous third-party audit by firms like Spearbit or Code4rena, supplemented by our internal review. We apply formal verification tools for critical circuit logic to mathematically guarantee security properties.
Phase 4: Integration & Production Deployment
Seamless integration with your existing backend and frontend. We handle mainnet deployment, monitoring setup (e.g., Tenderly, OpenZeppelin Defender), and provide detailed documentation for your team.

Frequently Asked Questions
Get clear answers on how we deliver secure, scalable, and compliant state synchronization for your Web3 application.
We deliver a production-ready, audited solution in 4-8 weeks for most projects. The timeline depends on the complexity of your data model and the number of chains involved. A standard single-chain DApp with basic private state requirements can be deployed in as little as 4 weeks, while multi-chain enterprise applications with complex logic may take 6-8 weeks. We provide a detailed project plan within the first week of engagement.
