overview
SECURE FOUNDATIONS

Smart Contract Development

Enterprise-grade smart contracts built with security-first development and comprehensive audit support.

We deliver production-ready smart contracts for ERC-20, ERC-721, and custom protocols, built on Solidity 0.8+ with OpenZeppelin standards. Our process includes formal verification and gas optimization to ensure cost-efficiency and security from day one.

  • Security Audits: Multi-stage review process culminating in a final audit report from leading security firms.
  • Gas Optimization: Achieve up to 40% lower transaction costs through optimized contract logic and storage patterns.
  • Upgradeability: Implement secure upgrade paths using Transparent Proxy or UUPS patterns for future-proof dApps.

We don't just write code; we engineer resilient systems. Every contract includes comprehensive test suites with >95% coverage and deployment scripts for mainnet and testnets.

The Infrastructure Decision for Your Bitcoin Subscription Business

Build vs. Buy vs. Chainscore

Choosing the right foundation for your Bitcoin-powered recurring billing is critical. Compare the time, cost, and risk of building from scratch, using a generic off-the-shelf API, or partnering with Chainscore for a purpose-built solution.
