Zero-Knowledge Oracle Circuit Design

We design and implement custom zero-knowledge circuits that enable oracles to deliver cryptographically verifiable off-chain data to smart contracts, with optional confidentiality for data sources and logic.

overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production at scale.

We architect and deploy custom smart contracts that power your core business logic, from ERC-20 tokens and ERC-721 NFTs to complex DeFi protocols. Every line of code is written for gas efficiency, security, and upgradability using established patterns like OpenZeppelin.

  • Full Lifecycle Development: Strategy, architecture, coding, testing, deployment, and maintenance.
  • Rigorous Security: Multi-stage audits, formal verification, and automated testing to prevent exploits.
  • Production-Ready: Built for mainnet with considerations for gas optimization and upgrade paths via proxies.

Deliver a secure, audited MVP in as little as 2-3 weeks, with a 99.9% uptime SLA post-launch.

Frequently Asked Questions

Common questions from CTOs and technical founders about our zero-knowledge oracle circuit design and implementation services.

A standard zero-knowledge oracle circuit for a single data feed (e.g., price feed with privacy) takes 4-6 weeks from specification to audit-ready circuits. Complex multi-source oracles with custom logic can take 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial scoping call.
