overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that form the backbone of your decentralized application. Our development process is built on security-first principles and proven patterns from day one.

  • Audit-Ready Code: Built with Solidity 0.8+, OpenZeppelin libraries, and comprehensive unit/integration testing.
  • Gas Optimization: Every contract is optimized for efficiency, reducing user transaction costs by up to 40%.
  • Full Lifecycle Support: From initial design and development to deployment, verification, and post-launch maintenance.

We deliver contracts you can trust, with a typical 2-3 week delivery cycle for an MVP core.

PROVEN METHODOLOGY

Our Development & Audit Process

A rigorous, multi-stage process designed to deliver secure, high-performance StarkNet Cairo contracts with predictable timelines and zero surprises.

01

Architecture & Specification

We begin with a collaborative deep-dive to define your privacy logic, data flow, and Cairo 1.0 architecture. This phase establishes clear requirements and a technical blueprint, ensuring alignment and preventing costly scope changes later.

StarkNet Privacy Contracts: Key Questions

Get clear, specific answers to the most common questions about our Cairo privacy contract development process, security, and delivery.

A complete StarkNet privacy contract deployment typically takes 2-4 weeks from kickoff to mainnet. This includes a 1-week design and scoping phase, 1-2 weeks of Cairo development and unit testing, and 1 week for security review and deployment. Complex protocols with custom ZK-circuits may extend to 6-8 weeks. We provide a detailed project plan with weekly milestones.
