Tailored Groth16 and Plonk circuits for your specific device attestation logic, ensuring proofs are generated and verified in under 2 seconds. We implement industry-standard security patterns from day one.
Integrate with TPMs, Secure Enclaves, and Hardware Security Modules (HSMs) to generate unforgeable attestation proofs. We bridge the gap between physical device security and on-chain verification.
Deploy optimized, gas-efficient verifier smart contracts on Ethereum, Polygon, and other EVM chains. Our contracts are audited and include upgrade patterns for long-term security.
Managed infrastructure for high-throughput proof generation with 99.9% uptime SLA. Auto-scaling node clusters handle spikes in verification demand without service degradation.
Implement selective disclosure protocols. Prove device ownership or specific attributes (e.g., OS version, location) without revealing the underlying raw data, ensuring user privacy.
From SDKs for mobile/web apps to monitoring dashboards. We provide full-stack integration kits and documentation to get your verification flow live in weeks, not months.
ZK-Proof Device Verification delivers concrete, measurable value beyond just technical implementation. Here's what our clients achieve.
Immutable, cryptographically verified data streams from edge devices. Eliminate fraud and data tampering risks for supply chain, energy, and sensor networks.
Replace expensive centralized trust models with lightweight ZK proofs. Slash operational costs for data verification and reconciliation by over 70%.
Automated, auditable proof of origin and data lineage. Meet stringent requirements for financial reporting, carbon credits, and secure hardware attestation.
Onboard millions of devices without trust bottlenecks. Our verification layer scales independently, enabling exponential DePIN growth with sub-second proof verification.
Transform verified device data into high-value, tradable assets. Create new revenue streams through oracle networks, prediction markets, and data marketplaces.
Built with modular circuits and multi-chain compatibility (EVM, Solana, Cosmos). Adapt to new consensus mechanisms and hardware standards without platform lock-in.

We deliver production-ready ZK-proof device verification systems using a structured, security-first approach that ensures reliability, scalability, and auditability from day one.
We design your system architecture and select the optimal ZK protocol (e.g., Plonk, Groth16, Halo2) based on your specific trust assumptions, proving time requirements, and hardware constraints.
Our engineers write and optimize zero-knowledge circuits in Circom or Noir, focusing on minimizing constraints and proof size to reduce operational costs and latency.
We implement high-performance provers (in Rust/C++) and lightweight on-chain verifier smart contracts (Solidity), ensuring gas efficiency and compatibility with your target chain.
Every component undergoes rigorous review. Circuits are checked for soundness, and verifier contracts are audited internally and by partners like Spearbit or Code4rena before deployment.
We handle end-to-end integration with your hardware/backend, deploy the verifier to mainnet/testnet, and set up monitoring for proof generation success rates and system health.
Post-launch, we provide support, performance monitoring, and iterative optimizations to reduce proving costs and integrate new ZK advancements as the ecosystem evolves.

Get clear answers on how our ZK-Proof Device Verification service secures your hardware and onboards users.
We integrate a lightweight SDK into your device firmware or mobile app. This SDK generates a unique, cryptographically secure identity for each device using a combination of hardware fingerprints and our proprietary ZK circuits. The device can then generate zero-knowledge proofs that attest to its authenticity and integrity without revealing the underlying sensitive data. These proofs are verified on-chain by your smart contracts, enabling secure, permissioned actions.
