overview
SECURE FOUNDATIONS
Smart Contract Development
Production-ready smart contracts built with enterprise-grade security and gas optimization.
- Full Lifecycle Support: From initial design and
Solidity 0.8+development to deployment, verification, and ongoing maintenance. - Gas-Optimized Code: We write for efficiency, reducing user transaction costs by up to 40% versus unaudited code.
- Multi-Chain Ready: Deployable on EVM chains (Ethereum, Polygon, Arbitrum) and Solana using
RustandAnchor. - Proven Security: Every contract undergoes internal review and is prepared for third-party audits from firms like CertiK or Quantstamp.
Deliver a secure, auditable, and performant smart contract foundation in as little as 3 weeks, accelerating your path to mainnet launch.

PROVEN METHODOLOGY
Our Development Process
A structured, security-first approach to delivering production-ready ZK-KYC infrastructure. We focus on rapid integration, regulatory compliance, and enterprise-grade reliability.
01
Discovery & Architecture
We analyze your compliance requirements, user flow, and chain support to design a tailored ZK-KYC architecture. This phase defines the proof circuits, data schemas, and integration points.

Frequently Asked Questions
Get clear answers on our development process, security, and support for your ZK-KYC integration.
A standard ZK-KYC SDK integration takes 2-4 weeks from kickoff to production-ready deployment. This includes customizing the proof circuits for your compliance rules, building the API layer, and implementing the frontend components. Complex multi-jurisdictional requirements or custom identity proofing logic can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones.
