Features Breakdown

🔗 Network Selection

🔗 Available chains:
1. Monad-Testnet    # Free testnet tokens
2. Arbitrum         # Lower gas fees  
3. Ethereum Mainnet # Main network
4. Base             # Coinbase L2

Common Errors

Error	Cause	Solution
PRIVATE_KEY not found	Missing environment variable	Add PRIVATE_KEY to .env
RPC URL not found	Missing RPC configuration	Add RPC URLs to .env
Invalid contract address	Wrong format	Use 0x... format
Insufficient balance	Not enough funds	Add more ETH/tokens
No mint steps found	Mint not active	Check if mint is live
Gas estimation failed	Network issues	Retry or use default gas

🔧 Insufficient Funds

💡 INSUFFICIENT FUNDS:
- Add more ETH to your wallet
- Check if you have enough for mint cost + gas fees

⚡ Transaction Issues

💡 NONCE ISSUE:
- Try again, transaction might have been replaced

🌐 Network Problems

💡 RPC CONNECTION:
- Check your internet connection
- Verify RPC URL in .env
- Try different RPC provider

Security

⚠️ Important Security Notes:

• Never share your private key
• Use testnet for testing
• Keep .env file secure
• Don't commit private keys to git

.gitignore

Make sure your .gitignore includes:

.env
node_modules/

Adding New Networks

1. Add network configuration

const networkNames = {
  10143: 'monad-testnet',
  42161: 'arbitrum', 
  1: 'ethereum',
  8453: 'base',
  // Add new network
  137: 'polygon'
};

2. Add currency symbol

const getCurrencySymbol = (chain) => {
  switch (chain) {
    case 'monad-testnet': return 'MON';
    case 'polygon': return 'MATIC';
    default: return 'ETH';
  }
};

3. Add RPC URL to .env

RPC_URL_POLYGON=

Testing

Testnet Testing

# Use Monad testnet for free testing
Select chain (1 - 4): 1

# Get testnet tokens from faucet
# Test with small amounts first

Mainnet Testing

# Start with small amounts
📦 How many to mint (default 1): 1

# Always verify contract address
# Check gas prices during high activity
