- Security First: Development with OpenZeppelin libraries, followed by third-party audits from firms like CertiK or Quantstamp.
- Full Lifecycle: From initial design and testing on
Hardhat/Foundryto deployment and verification on mainnet.
Deliver a secure, audited, and gas-efficient contract suite in 2-4 weeks, ready for production launch.
Our ZK Circuit Engineering Capabilities
We architect and implement zero-knowledge circuits that deliver verifiable computation with enterprise-grade performance and security. Our focus is on practical applications that reduce costs and unlock new product capabilities.
Custom Circuit Design & Implementation
From concept to compiled R1CS, we build custom zk-SNARK and zk-STARK circuits for privacy, scalability, and compliance. We specialize in complex business logic for DeFi, identity, and gaming.
Gas & Performance Optimization
We engineer circuits for minimal on-chain verification costs and prover efficiency. Our optimizations target constraint count reduction and strategic use of lookup tables and custom gates.
Security Audits & Formal Verification
Every circuit undergoes rigorous review using manual audit techniques and symbolic execution tools. We provide a verifiable security report to ensure soundness and correctness.
Recursive Proof & Rollup Integration
Build scalable L2s and privacy layers. We implement recursive proof aggregation and seamless integration with rollup frameworks like Scroll, zkSync, and Polygon zkEVM.
Trusted Setup Ceremony Coordination
We manage secure Powers of Tau and circuit-specific trusted setup ceremonies using best practices for contributor anonymity and toxic waste disposal.
End-to-End Prover/Verifier Systems
We deliver complete systems, including high-performance provers (WASM/Rust) and lightweight on-chain verifiers, ensuring your application is production-ready.
Business Outcomes of Bespoke Circuit Design
Our custom zero-knowledge circuit development translates directly into measurable business advantages, from cost reduction to market leadership. We architect circuits that solve your specific problem, not generic ones.
Substantial Cost Reduction
Bespoke circuits are optimized for your specific use case, dramatically reducing on-chain gas fees and operational overhead. We target a 50-80% reduction in transaction costs compared to generic or poorly-optimized implementations.
Unmatched Scalability
We design circuits with computational efficiency as a first principle, enabling your application to handle thousands of private transactions per second (TPS). This future-proofs your infrastructure against user growth and network congestion.
Proven Security & Compliance
Every circuit undergoes a rigorous security review following industry standards. We provide formal verification reports and work with leading auditors like Trail of Bits to ensure your logic is bulletproof and compliant with regulatory requirements for data privacy.
Faster Time-to-Market
Leverage our battle-tested development frameworks and reusable libraries for common primitives (e.g., Merkle trees, signature schemes). We deliver production-ready circuits in 4-8 weeks, accelerating your product launch and competitive edge.
Unique Product Differentiation
Move beyond standard privacy features. We engineer novel cryptographic constructs—like custom proof systems or privacy-preserving oracles—that become your application's defensible moat and primary selling proposition.
Future-Proof Architecture
Our designs are modular and upgradeable, allowing you to seamlessly integrate new proof systems (e.g., moving from Groth16 to PLONK) or scale to new chains. Avoid vendor lock-in and technical debt with forward-compatible circuit logic.

Our End-to-End Delivery Process
We deliver production-ready ZK circuits with rigorous security and performance guarantees. Our structured process ensures predictable timelines, transparent communication, and auditable results.
Architecture & Specification
We collaborate to define the precise computational statement for your zero-knowledge proof. This includes selecting the optimal proving system (e.g., Plonk, Groth16), circuit architecture, and performance requirements.
Circuit Development & Optimization
Our engineers implement the circuit logic in Circom or Halo2, focusing on constraint efficiency and prover performance. We apply advanced optimization techniques to minimize proof generation time and verification gas costs.
Security Audit & Formal Verification
Every circuit undergoes a multi-layered security review. This includes automated analysis with tools like Picus and manual review by our senior cryptographers to eliminate logical flaws and side-channel vulnerabilities.
Prover Infrastructure & Integration
We deploy and configure high-performance proving servers (CPU/GPU) and deliver a seamless integration package. This includes client SDKs, API endpoints, and comprehensive documentation for your engineering team.
Performance Benchmarking
We provide detailed benchmark reports comparing proof times, verification gas costs, and trusted setup requirements against industry standards. This data validates the economic viability of your ZK application.
Production Deployment & Support
We manage the final deployment to your mainnet environment, including any required trusted setup ceremonies. Post-launch, we offer ongoing support and maintenance plans to ensure long-term reliability.
ZK Circuit Development FAQs
Get clear answers to the most common questions about our custom zero-knowledge circuit development process, timelines, and security standards.
Our standard development cycle is 6-10 weeks from specification to audit-ready circuit. This includes 2 weeks for design & specification, 3-5 weeks for circuit implementation in Circom or Halo2, and 1-3 weeks for internal testing and optimization. Complex protocols with custom cryptographic primitives may extend to 12-14 weeks. We provide a detailed project plan with weekly milestones.
