overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by experts for DeFi, NFTs, and enterprise applications.

We architect and deploy audit-ready smart contracts that power your core business logic. Our development process is built on security-first principles using Solidity 0.8+, OpenZeppelin libraries, and comprehensive testing suites to mitigate risks before mainnet deployment.

Deliver a secure, functional MVP in as little as 2-4 weeks, accelerating your time-to-market while ensuring long-term maintainability.

  • Custom Logic: Tailored ERC-20, ERC-721, ERC-1155, and bespoke contract development for DeFi protocols, marketplaces, and DAOs.
  • Security & Audits: Rigorous internal review, formal verification, and preparation for third-party audits from firms like CertiK or Quantstamp.
  • Gas Optimization: Expert-level code optimization to reduce transaction costs by 15-40%, directly impacting user adoption and protocol economics.
  • Full Lifecycle Support: From initial design and development to deployment, upgrade management, and ongoing maintenance on EVM-compatible chains like Ethereum, Polygon, and Arbitrum.

Frequently Asked Questions

Get clear answers on our Cairo oracle node development, deployment, and support process.

A standard, production-ready Cairo oracle node deployment takes 2-4 weeks from kickoff to mainnet launch. This includes architecture design, smart contract development, node configuration, and comprehensive testing. Complex integrations (e.g., multi-chain data aggregation, custom consensus) can extend this to 6-8 weeks. We provide a detailed project plan during the initial consultation.
