# 🔐 Security Guide - Private Key Management

## ⚠️ CRITICAL SECURITY WARNING

**NEVER share, commit, or expose your private keys or seed phrases!**

## 🛡️ Safe Private Key Handling

### Option 1: Secure Environment Setup (Recommended)
```bash
# Run the secure setup script
node setup-secure-env.cjs
```

This will:
- ✅ Prompt for your private key securely
- ✅ Create a .env file with proper security
- ✅ Never log or store your key in plain text
- ✅ Provide security checklist

### Option 2: Manual .env Setup
```bash
# Create .env file manually
echo "PRIVATE_KEY=your_private_key_here" > .env
```

## 🔒 Security Best Practices

### ✅ DO:
- Use **testnet wallets only** for development
- Keep private keys in `.env` files
- Add `.env` to `.gitignore`
- Delete `.env` after deployment if needed
- Use hardware wallets for mainnet
- Verify network before deployment

### ❌ DON'T:
- Never commit private keys to version control
- Never share private keys in chat/email
- Never use mainnet wallets for testing
- Never store keys in plain text files
- Never use the same key for multiple purposes

## 🚨 Emergency Procedures

### If Private Key is Compromised:
1. **Immediately transfer all funds** to a new wallet
2. **Revoke any permissions** granted to the compromised key
3. **Generate a new wallet** with new private key
4. **Update all systems** with new key
5. **Monitor for unauthorized transactions**

## 🔐 Wallet Security Levels

### Level 1: Testnet (Development)
- ✅ Use any testnet wallet
- ✅ Private key can be in .env files
- ✅ No real value at risk

### Level 2: Mainnet (Production)
- ✅ Use hardware wallets only
- ✅ Multi-signature wallets
- ✅ Never store keys in code
- ✅ Use secure key management services

## 📋 Security Checklist

Before deployment:
- [ ] Using testnet wallet only
- [ ] Private key in .env file
- [ ] .env in .gitignore
- [ ] Network verified (Base Sepolia)
- [ ] Sufficient ETH for gas
- [ ] Backup wallet created
- [ ] Security guide reviewed

## 🛠️ Secure Deployment Commands

```bash
# 1. Setup secure environment
node setup-secure-env.cjs

# 2. Run secure deployment
node secure-deploy.cjs

# 3. Verify deployment
node verify-deployment.cjs
```

## 🔍 Verification Steps

After deployment:
1. **Check contract addresses** on BaseScan
2. **Verify contract code** is correct
3. **Test all functions** work properly
4. **Monitor for issues** in first 24 hours
5. **Document deployment** details
