Privacy-Preserving Data Query Marketplace

We build secure marketplaces that allow third parties to run analytical queries on encrypted DePIN and IoT datasets. Extract insights without ever exposing the underlying sensitive data, using MPC and homomorphic encryption.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles, utilizing OpenZeppelin libraries, formal verification, and multi-stage audits to mitigate risk.

  • Token Standards: ERC-20, ERC-721, ERC-1155, and custom implementations.
  • DeFi Protocols: DEXs, lending/borrowing platforms, yield aggregators, and staking contracts.
  • Enterprise Logic: Multi-signature wallets, DAO governance, and asset tokenization frameworks.
  • Audit-Ready Code: Comprehensive documentation, test coverage >95%, and gas optimization reports.

From initial concept to mainnet deployment, we ensure your contracts are secure, efficient, and maintainable, reducing time-to-market from months to weeks.
