CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We deliver battle-tested contracts, not just code. Every line is written for security, auditability, and long-term maintainability.
- End-to-End Development: From initial spec and
Solidity/Rustdevelopment to deployment and verification onEVM,Solana, orCosmoschains. - Security-First Approach: All contracts follow OpenZeppelin standards and undergo internal review before external audit.
- Measurable Outcomes: Achieve 99.9% uptime SLAs, gas cost reductions up to 40%, and deployment-ready code in as little as 2 weeks.

Smart Contract Upgrade & Migration
Build In-House vs. Partner with Chainscore
A direct comparison of the time, cost, and risk involved in managing complex smart contract upgrades internally versus leveraging our specialized service.
| Key Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to First Upgrade | 3-6 months | 2-4 weeks |
Upfront Development Cost | $150K - $300K+ | $25K - $75K |
Security & Audit Overhead | High (Manual, variable quality) | Low (Automated + expert review) |
Protocol-Specific Expertise | Must be hired/developed | Included (EIP-2535, UUPS, Beacon) |
Post-Migration Monitoring | Your team's responsibility | Included for 30 days |
Risk of Downtime / Bugs | High (Single point of failure) | Low (Tested migration paths) |
Total Cost of Ownership (Year 1) | $200K - $500K | $50K - $150K |
Access to Latest Patterns | Requires constant R&D | Built into service (EIPs, security best practices) |
