A Cost-Benefit Analysis
Build vs. Buy: The Cost of In-House Upgrade Testing
Compare the total cost of ownership and risk profile of building a custom upgrade testing framework versus using Chainscore's proven suite.
| Factor | Build In-House | Chainscore Suite |
|---|---|---|
Development Timeline | 6-12 months | 4-8 weeks |
Initial Security Audit | High Risk (Unaudited) | Low Risk (Pre-Audited) |
Coverage of Edge Cases | Limited (Team Knowledge) | Comprehensive (500+ Test Vectors) |
Maintenance & Updates | Ongoing Team Burden | Handled by Chainscore |
Integration Complexity | High (Custom Tooling) | Low (Standardized SDK) |
Total Year 1 Cost | $250K - $600K+ | $75K - $200K |
Time-to-Market Delay | Significant (6+ months) | Minimal (< 2 months) |
Auditor Confidence | Variable | Consistently High |

A PROVEN PROCESS
Our Methodology: From Audit to Automated Regression
Our systematic approach to upgradeability testing ensures your smart contracts remain secure, functional, and compliant through every iteration. We move beyond one-time audits to establish a continuous security posture.
01
Comprehensive Initial Audit
We perform a deep-dive security audit of your existing upgradeable architecture (e.g., UUPS, Transparent Proxy) and governance mechanisms. Our experts identify critical vulnerabilities in initialization, storage collisions, and access control before deployment.
100%
Code Coverage

Custom Test Suite Development
We build a bespoke, automated test suite in Hardhat or Foundry tailored to your specific upgrade logic and business rules. This includes invariant testing, fuzzing for edge cases, and simulation of complex upgrade scenarios.

03
CI/CD Pipeline Integration
We integrate the automated test suite directly into your GitHub Actions or GitLab CI pipeline. Every pull request triggers a full regression test, preventing breaking changes from being merged and ensuring upgrade safety.
