overview
SECURE FOUNDATIONS

Smart Contract Development

Production-ready smart contracts built with enterprise-grade security and gas optimization.

We architect and deploy custom smart contracts that form the core logic of your dApp. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and comprehensive audit practices to mitigate risk before deployment.

  • 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 Rust and Anchor.
  • 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.

CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications.

We architect, develop, and deploy production-grade smart contracts that power your Web3 application. From custom tokenomics and decentralized logic to gas-optimized execution, we ensure your on-chain foundation is robust and reliable.

Every contract is built with security-first principles, undergoing rigorous internal review before external audit.

  • Custom Development: ERC-20, ERC-721, ERC-1155, and bespoke protocols.
  • Security & Audits: Pre-audit code review, integration with firms like CertiK or OpenZeppelin.
  • Gas Optimization: Reduce user transaction costs by up to 40% through efficient code patterns.
  • Full Lifecycle Support: Development, testing, deployment, and upgrade management via Transparent Proxies.

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.
