Cosmos IoT Data Marketplace Development

We build application-specific, interoperable IoT data marketplaces on Cosmos SDK chains. Our solutions enable secure, cross-chain data trading via IBC and CosmWasm smart contracts, turning sensor data into a tradable asset.

CORE ENGINEERING

Smart Contract Development

Secure, gas-optimized smart contracts built to your exact specifications.

We architect and deploy production-grade smart contracts that form the foundation of your Web3 product. Our process delivers secure, auditable, and maintainable code from day one.

  • End-to-End Development: From initial design and Solidity/Rust coding to deployment on EVM or Solana.
  • Security-First: All code follows OpenZeppelin standards and undergoes rigorous internal review before third-party audits.
  • Gas Optimization: We minimize transaction costs by 20-40% through advanced optimization techniques.

Deploy a battle-tested MVP in as little as 2 weeks, not months.

We specialize in:

  • Token Standards: Custom ERC-20, ERC-721, and ERC-1155 implementations.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators.
  • Utility Contracts: Multi-signature wallets, vesting schedules, and governance modules.

Frequently Asked Questions for Technical Decision-Makers

Technical and commercial questions we commonly receive from CTOs and engineering leads evaluating development partners.

From kickoff to mainnet launch, a typical project takes 8-12 weeks. This includes a 2-week discovery/design phase, 4-6 weeks of core development (IBC integration, custom modules, smart contracts), and 2-4 weeks for testing, security audits, and deployment. We provide a detailed Gantt chart during the proposal stage.
