Blockchain-Agnostic Identity Layer

A standardized API suite that abstracts chain-specific complexity, providing a single interface for KYC, identity verification, and compliance operations across EVM, Solana, and Cosmos ecosystems.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built for production by expert Solidity engineers.

We architect and deploy production-ready smart contracts on EVM chains like Ethereum, Polygon, and Arbitrum. Our development process is built for security and efficiency from day one.

  • Security-First Architecture: Code is built with OpenZeppelin standards, undergoes rigorous internal audits, and is prepared for third-party review.
  • Gas Optimization: Every function is profiled to minimize transaction costs, a critical factor for user adoption and protocol sustainability.
  • Full-Stack Integration: We deliver contracts with comprehensive testing, deployment scripts, and documentation for your front-end team.

Move from concept to a secure, audited mainnet deployment in as little as 4-6 weeks.

Our deliverables are built for the long term:

  • Upgradeable Contracts: Using transparent proxy patterns (UUPS) for seamless future improvements.
  • Comprehensive Test Suite: Unit and integration tests achieving >95% coverage.
  • Technical Documentation: Clear NatSpec comments and integration guides for your developers.
