Cross-Platform API Gateway Development

We build unified API gateways that abstract the complexity of multiple blockchain protocols, providing enterprises with a single, consistent interface for all their on-chain operations.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts for your protocol or dApp.

We architect and deploy audit-ready smart contracts that form the foundation of your product. Our development process is built on security-first principles using Solidity 0.8+, OpenZeppelin libraries, and rigorous internal testing to prevent costly vulnerabilities before the first line of audit.

Deliver a secure, functional MVP in as little as 2-4 weeks with our streamlined development sprints.

  • Custom Logic & Architecture: Design for ERC-20, ERC-721, ERC-1155, or bespoke standards.
  • Gas Optimization: Write efficient code to minimize user transaction costs.
  • Integration Ready: Built with clear interfaces for easy frontend and backend connection.
  • Full Documentation & Testing: Comprehensive NatSpec comments and test coverage exceeding 95%.
