Smart City Infrastructure Oracle Consulting

Strategic consulting and system design for municipalities and enterprises to integrate secure, reliable blockchain oracles with public infrastructure data streams like traffic, utilities, and air quality.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contract systems built to your exact specifications.

We architect and deploy production-ready Solidity/Rust smart contracts that are secure by design. Every line of code is built with OpenZeppelin standards, undergoes rigorous internal audits, and is optimized for gas efficiency and upgradability.

From tokenomics to complex DeFi logic, we deliver contracts you can stake your business on.

Our development process is tailored for speed and safety:

  • Custom Logic: Build ERC-20, ERC-721, staking pools, oracles, and bespoke DeFi primitives.
  • Security-First: Multi-stage review using Slither/MythX and adherence to Consensys best practices.
  • Full Lifecycle: Development, testing on Hardhat/Foundry, deployment, and verification on-chain.

We ensure your contracts are future-proof and maintainable. This includes implementing upgrade patterns like Transparent Proxy or UUPS, comprehensive documentation, and clear handover for your team.
