BUILD

Custom Blockchain Development

End-to-end development of secure, scalable blockchain networks and applications tailored to your business logic.

We architect and build custom blockchains and dApps from the ground up. Our full-cycle development delivers production-ready networks in 6-12 weeks, from initial PoC to mainnet deployment. We specialize in:

Layer 1 & 2 Solutions: EVM-compatible chains, app-specific rollups (Arbitrum, Optimism), and sidechains.
Smart Contract Suites: Gas-optimized Solidity/Rust contracts with formal verification and audit readiness.
Full-Stack dApps: Integrated frontends (React, Next.js) with secure wallet connectivity and indexers.

We don't just write code; we deliver audited, maintainable systems with documented APIs and a clear handoff process.

Our process ensures your core business logic is correctly encoded on-chain, resulting in:

Faster time-to-market with iterative development sprints.
Reduced long-term costs via optimized architecture and clear documentation.
Enterprise-grade security through integrated testing and audit partnerships.

COMPREHENSIVE VERIFICATION

What Our ZK Compliance Audit Covers

Our audit delivers a formal, evidence-backed verification report, giving your team and regulators confidence that your zero-knowledge circuits correctly enforce compliance rules without leaking sensitive data.

Circuit Logic & Constraint Verification

We verify that your ZK circuit's constraints and arithmetic gates correctly implement the specified compliance rules (e.g., AML checks, KYC thresholds, transaction limits). This ensures proofs are only generated for valid, rule-abiding states.

Cryptographic Soundness & Security

We audit the underlying cryptographic primitives (e.g., Pedersen commitments, Poseidon hashes) and proof systems (Groth16, Plonk) for implementation flaws, side-channel risks, and adherence to formal security specifications.

Privacy Leakage Analysis

We perform differential privacy and information leakage analysis to ensure your circuit's public outputs and proofs do not inadvertently reveal sensitive user data or business logic, preserving the core promise of ZK.

Gas & Performance Optimization Review

We analyze on-chain verifier contract efficiency and prover complexity. Our review identifies optimizations to reduce verification gas costs by up to 40% and improve prover speed for better user experience.

Regulatory Alignment Assessment

We map your circuit's logic to specific regulatory requirements (e.g., FATF Travel Rule, MiCA, OFAC sanctions) and provide a gap analysis to ensure technical implementation aligns with legal obligations.

Integration & Upgrade Safety

We verify the safety of circuit upgrades and integration points with your application's smart contracts and off-chain provers, preventing logic mismatches that could break compliance or cause financial loss.

SECURITY & REGULATORY CERTAINTY

Why a Specialized Compliance Circuit Audit is Critical

Standard smart contract audits miss the unique cryptographic and regulatory risks of ZK circuits. Our specialized audit delivers the technical rigor and compliance verification required for production-grade financial applications.

Cryptographic Soundness Verification

We perform deep mathematical analysis of your circuit's constraints, zero-knowledge proofs, and trusted setup to eliminate vulnerabilities like soundness errors, front-running, and proof forgery.

Proof Verification

Regulatory Logic Alignment

We map your circuit's business logic against specific regulatory frameworks (e.g., FATF Travel Rule, MiCA, OFAC sanctions) to ensure automated compliance is enforceable and auditable on-chain.

Technical & Commercial Clarity

Frequently Asked Questions on ZK Compliance Audits

Get specific answers on timelines, costs, and technical details for implementing zero-knowledge proofs for regulatory compliance.

A standard ZK compliance circuit audit and integration takes 4-6 weeks from kickoff to production deployment. This includes 1-2 weeks for requirements analysis and circuit design, 2-3 weeks for development and internal testing, and 1 week for external audit and final deployment. Complex multi-jurisdictional requirements can extend this to 8-10 weeks.
