PR Review Analysis

Todo List:

• Read and analyze hardhat.config.ts changes
• Read and analyze src/addresses.ts changes
• Identify critical issues and necessary improvements
• Provide focused feedback

Critical Issues Found

hardhat.config.ts:25 - Security Risk

Issue: Hardcoded dummy API key 'abc123abc123abc123abc123abc123abc1' in etherscan configuration.

Risk: While this is labeled as a "dummy key", having predictable/hardcoded values in configuration can create security issues if this pattern is replicated elsewhere or if the dummy key is accidentally used in production environments.

Recommendation: Use environment variable with fallback:

apiKey: {
  shapeSepolia: process.env.ETHERSCAN_API_KEY || 'verification-disabled',
}

src/addresses.ts:15 - Incomplete Contract Configuration

Issue: nftMinter contract uses zeroAddress for mainnet deployment.

Risk: This creates a potential runtime issue where mainnet operations would fail silently or cause unexpected behavior when interacting with the zero address.

Recommendations:

1. Add validation in tools that use this address to check for zero address
2. Consider throwing an error or warning when accessing undeployed contracts
3. Add a deployment status flag to track which contracts are actually deployed

Minor Issues

hardhat.config.ts:20 - Missing validation for PRIVATE_KEY format. Consider adding basic validation to ensure it's a valid private key format.

Summary

Main concerns are the hardcoded API key (security) and zero address usage (runtime reliability). The hardhat verify configuration appears functional but needs better security practices.
