Zero-Knowledge Compliance Vault Development

We develop custom zero-knowledge circuits using Circom, Halo2, and Noir to encode your specific compliance logic (e.g., sanctions screening, transaction limits) into verifiable proofs. This ensures privacy is preserved without sacrificing auditability.

Every component undergoes rigorous security review. Our development follows OpenZeppelin standards, and final systems are audited by leading firms like Trail of Bits or Quantstamp before mainnet deployment.

Deploy your compliance logic seamlessly across Ethereum, Polygon zkEVM, zkSync Era, Starknet, and other EVM/L2 networks. We handle the cross-chain state synchronization and proof verification infrastructure.

Automated, off-chain proof generation service that produces verifiable attestations for transactions. Provides regulators with cryptographic proof of compliance without exposing sensitive user data.

Highly efficient Solidity/Yul verifier smart contracts that minimize on-chain verification costs. Critical for maintaining low transaction fees while adding ZK proof verification.

We provide and manage the scalable backend infrastructure for proof generation, including secure key management, high-availability provers, and monitoring dashboards, so you can focus on your core product.

We define your vault's compliance logic and design the optimal ZK circuit architecture. This phase delivers a functional PoC demonstrating core privacy and verification flows, validating feasibility before major investment.

Deliverables: Technical specification, circuit design document, working PoC on testnet.

Our team builds the production-grade zkSNARK/STARK circuits for your compliance rules and the associated smart contracts for vault management and verification. All code follows OpenZeppelin standards and is documented for your team.

Deliverables: Auditable circuit code (Circom/Halo2), Solidity smart contracts, comprehensive documentation.

We subject the entire system—circuits and contracts—to rigorous internal review and partner with leading firms like Spearbit or Zellic for external audits. We then implement all recommendations and perform final gas and proof generation optimization.

Deliverables: Internal audit report, external audit certification, optimized final codebase.

We integrate the vault with your existing front-end and back-end systems, conduct end-to-end testing on a staging environment, and manage the secure, phased deployment to mainnet. We provide full operational runbooks for your team.

Deliverables: Integration support, deployment scripts, mainnet launch, operational documentation.
