Bug: The package.json is updated to use hardhat@2.28.0, a version that does not appear to exist on the public npm registry, which will cause installation failures.
_{Severity: CRITICAL | Confidence: High}

🔍 Detailed Analysis

The pull request updates the hardhat dependency to version 2.28.0. However, this version is not available on the public npm registry, where the latest v2 release is 2.27.1. Consequently, any attempt to install project dependencies using package managers like bun install or npm install will fail because the specified version cannot be resolved. This will block development environment setup and break CI/CD pipelines.

💡 Suggested Fix

Revert the hardhat version back to a known, stable, and publicly available version, such as 2.27.1. If a specific pre-release or private version is intended, ensure the package manager is configured with the correct registry to resolve it.
