EXPERTISE & DELIVERABLES
Core Capabilities of Our ZK Circuit Design Service
We architect and implement zero-knowledge circuits that enable secure, scalable, and private attestation for IoT ecosystems. Our service delivers production-ready circuits optimized for your specific hardware and business logic.
01
Custom Circuit Architecture
We design ZK circuits from the ground up using Circom or Halo2, tailored to your IoT device's unique attestation logic and constraints. This ensures minimal proof size and verification cost for your specific use case.
Circom 2.1+
Primary Framework
Halo2
Alternative Framework
02
Hardware Constraint Integration
Our circuits are built with your IoT hardware (TPMs, HSMs, Secure Elements) in mind. We model hardware signatures and attestation reports as private inputs, creating efficient proofs of legitimate device state.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy audit-ready smart contracts that form the foundation of your protocol. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and formal verification patterns to mitigate risks before the first line of code is written.
From custom tokenomics to complex DeFi logic, we translate your business requirements into immutable, gas-efficient code.
- End-to-End Development: Full lifecycle from architecture and
Solidity/Rustcoding to testing, deployment, and mainnet launch. - Security as Standard: Every contract undergoes internal review and is structured for seamless third-party audits by firms like
CertiKorQuantstamp. - Protocol Specialization: Expertise in
ERC-20,ERC-721,ERC-1155, staking systems, automated market makers (AMMs), and cross-chain bridges.

Frequently Asked Questions
Get clear answers on how our Zero-Knowledge Circuit development secures your physical IoT infrastructure.
From requirements to production-ready circuit, typical delivery is 4-8 weeks. This includes a 2-week discovery and design phase, 3-5 weeks of development and internal testing, and a final week for integration and deployment support. Complex multi-device ecosystems or novel cryptographic primitives may extend this timeline, which we scope during the initial assessment.
