Custom ZK Circuit Library Development
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full-Stack Development: From
ERC-20tokens to complexDeFiprotocols,NFTmarketplaces, and cross-chain bridges. - Security & Audits: Code is developed with
OpenZeppelinlibraries and undergoes rigorous internal review before third-party audits. - Gas Optimization: Every contract is optimized for minimum execution cost, a critical factor for user adoption and scalability.
We deliver battle-tested contracts with clear documentation, enabling your team to iterate and scale with confidence.
What Our ZK Circuit Libraries Deliver
We build high-performance, auditable ZK circuits that solve real-world problems, from private transactions to verifiable compute. Our libraries are designed for immediate integration and long-term scalability.
Gas-Optimized Constraint Systems
We architect circuits with minimal constraints using techniques like custom gates and lookup tables, reducing on-chain verification costs by up to 40% compared to generic implementations.
Formally Verified Core Primitives
Critical cryptographic components like hash functions (Poseidon, SHA) and signature schemes are formally verified for correctness, providing mathematical guarantees against logical bugs.
Modular & Composable Design
Our libraries are built as reusable, well-documented modules (e.g., Merkle trees, range proofs) that you can snap together, accelerating development of complex protocols like rollups or private DeFi.
Performance-Tuned for Your Use Case
We benchmark and optimize for your specific requirements: faster proof generation for user-facing apps or smaller proofs for cost-sensitive on-chain verification.
Comprehensive Audit & Documentation
Every library includes detailed technical specifications, threat models, and passes rigorous internal review. We provide the clarity needed for external audits and team onboarding.
Business Outcomes: Faster, Safer, Scalable L2 Apps
Our custom ZK circuit libraries are engineered for production, delivering measurable improvements in performance, security, and scalability for your Layer 2 application.
Accelerated Time-to-Market
Leverage our pre-verified, modular circuit components to bypass months of foundational R&D. We deliver production-ready libraries, enabling you to launch your ZK-powered L2 or feature in 6-8 weeks.
Provably Secure Architecture
Every circuit library undergoes formal verification and peer review by our in-house cryptographers. We implement industry-standard security patterns and provide comprehensive audit trails, mitigating critical risks before mainnet deployment.
Sub-Second Finality & High TPS
Optimize for performance with circuits designed for minimal proof generation time and verification gas costs. Achieve sub-second finality and scale to 2,000+ TPS on your custom L2 stack.
Cost-Efficient Scaling
Reduce operational costs with gas-optimized verification circuits and efficient proof systems. Our libraries can lower on-chain verification costs by up to 40% compared to generic implementations.

Our Development & Delivery Process
We deliver production-ready ZK circuit libraries through a structured, transparent process designed for security, speed, and seamless integration.
Architecture & Specification
We begin with a deep technical discovery to define circuit logic, constraints, and performance targets. We deliver a formal specification document and a high-level architecture diagram for stakeholder alignment.
Circuit Design & Implementation
Our cryptographers implement the logic in Circom or Halo2, focusing on constraint efficiency and proof generation speed. We follow best practices for zero-knowledge circuit security from day one.
Performance Optimization
We benchmark and optimize for prover time, verifier gas costs, and proof size. This phase ensures your application remains cost-effective and responsive at scale.
Integration & SDK Delivery
We deliver a clean, documented TypeScript/Go SDK with examples, enabling your engineering team to generate and verify proofs with minimal friction. We provide direct support during integration.
Maintenance & Upgrades
We offer ongoing support packages for circuit maintenance, dependency updates (e.g., for new proving backends), and performance tuning as your application scales.
Blockchain Infrastructure for FinTechs
Reliable, scalable node infrastructure and APIs to power your financial applications.
We provide managed infrastructure so you can focus on your product, not on node operations. Our service delivers 99.9% uptime SLAs, multi-region redundancy, and real-time monitoring for mission-critical applications.
- Full Node Suite: Dedicated
EVM(Ethereum, Polygon, Arbitrum) andSolanaRPC endpoints with archival data. - Enhanced APIs: Pre-built for common needs: transaction simulation, gas estimation, and smart contract event streaming.
- Security & Compliance: SOC 2 Type II compliant infrastructure with dedicated VPCs and IP allowlisting.
Deploy production-ready infrastructure in under 48 hours, eliminating months of DevOps overhead and capital expenditure on hardware.
Frequently Asked Questions
Get clear answers on our process, timelines, and technical approach for building custom zero-knowledge circuit libraries.
We deliver a production-ready, audited ZK circuit library in 4-8 weeks for most projects. The timeline depends on the complexity of the proving system (e.g., Groth16, Plonk, Halo2), the number of custom constraints, and the required integration depth. A standard library with 5-10 core operations typically takes 4-5 weeks from spec to audit-ready code.
