CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts that are secure by design and gas-optimized. Our development process includes formal verification and comprehensive testing against known attack vectors to ensure your core logic is bulletproof.

  • Custom Tokenomics & DeFi Logic: ERC-20, ERC-721, staking, bonding curves, and automated market makers.
  • Multi-Chain Deployment: Deployments on Ethereum, Polygon, Arbitrum, Base, and other leading EVM chains.
  • Full Audit Readiness: Code is structured with OpenZeppelin standards and includes detailed documentation for seamless third-party audit.

We deliver a complete, battle-tested contract suite in 2-4 weeks, from specification to mainnet deployment, giving you a secure foundation to build upon.

PROVEN FRAMEWORK

Our Development & Security Methodology

Our systematic approach ensures your StarkNet-based credit scoring system is built for scale, security, and regulatory readiness from day one.

01

Architecture & Design Review

We conduct a comprehensive technical deep dive to design a modular, upgradeable Cairo architecture that isolates core logic from scoring models, ensuring long-term maintainability and flexibility.

Frequently Asked Questions

Get clear answers about our StarkNet Cairo development process, security, and support for your on-chain credit scoring system.

From initial design to mainnet deployment, a standard implementation takes 4-8 weeks. This includes 1-2 weeks for requirements & architecture, 2-4 weeks for core Cairo contract development, and 1-2 weeks for auditing, testing, and deployment. Complex integrations (e.g., multi-chain oracles, custom scoring models) can extend this timeline. We provide a detailed project plan within the first week of engagement.
