Environment Variable Check - PRIVATE_KEY

Date: 2025-12-24
Purpose: Check for PRIVATE_KEY in .env files

---

Check Results

.env File Status

Location: /home/intlc/projects/proxmox/smom-dbis-138/.env

Status: ⚠️ .env file not found in repository

Note: .env files are typically excluded from version control for security reasons.

How to Check PRIVATE_KEY

Method 1: Check if .env exists and contains PRIVATE_KEY

cd /home/intlc/projects/proxmox/smom-dbis-138

# Check if .env exists
if [ -f .env ]; then
    echo "✅ .env file exists"
    
    # Check if PRIVATE_KEY is set (without showing the value)
    if grep -q "^PRIVATE_KEY=" .env; then
        echo "✅ PRIVATE_KEY is set in .env"
        # Show first few characters for verification (optional)
        grep "^PRIVATE_KEY=" .env | sed 's/\(.\{10\}\).*/PRIVATE_KEY=\1...***HIDDEN***/'
    else
        echo "⚠️  PRIVATE_KEY is NOT set in .env"
    fi
else
    echo "⚠️  .env file does not exist"
    echo "Create it from .env.template if available"
fi

Method 2: Check environment variable directly

# Check if PRIVATE_KEY is set in current environment
if [ -z "$PRIVATE_KEY" ]; then
    echo "⚠️  PRIVATE_KEY is not set in environment"
else
    echo "✅ PRIVATE_KEY is set in environment"
    # Get deployer address from private key
    cast wallet address $PRIVATE_KEY 2>/dev/null || echo "Invalid PRIVATE_KEY format"
fi

Method 3: Check from deployment scripts

The deployment scripts expect PRIVATE_KEY to be set via:

• Environment variable: export PRIVATE_KEY=<key>
• .env file: PRIVATE_KEY=<key>
• Foundry's vm.envUint("PRIVATE_KEY") in scripts

---

Expected Format

PRIVATE_KEY should be:

• Without 0x prefix: 1234567890abcdef... (64 hex characters)
• Or with 0x prefix: 0x1234567890abcdef... (66 characters total)

Example:

PRIVATE_KEY=1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef

---

Security Notes

⚠️ NEVER commit .env files to version control

The .env file should be in .gitignore:

.env
.env.local
.env.*.local

---

Creating .env File

If .env doesn't exist, create it:

cd /home/intlc/projects/proxmox/smom-dbis-138

# Create .env file
cat > .env <<EOF
# Chain 138 RPC
RPC_URL_138=http://192.168.11.250:8545
RPC_URL=http://192.168.11.250:8545

# Deployer Private Key (REQUIRED)
PRIVATE_KEY=<your_private_key_here>

# Optional: Admin addresses (defaults to deployer if not set)
COMPLIANCE_ADMIN=
TOKEN_REGISTRY_OWNER=
FEE_COLLECTOR_OWNER=
EOF

# Set permissions (read-only for owner)
chmod 600 .env

---

Verification

After setting PRIVATE_KEY, verify it works:

# Load .env
source .env

# Verify deployer address
DEPLOYER=$(cast wallet address $PRIVATE_KEY 2>/dev/null)
if [ -z "$DEPLOYER" ]; then
    echo "❌ Invalid PRIVATE_KEY"
else
    echo "✅ PRIVATE_KEY is valid"
    echo "Deployer address: $DEPLOYER"
    
    # Check balance
    BALANCE=$(cast balance $DEPLOYER --rpc-url $RPC_URL 2>/dev/null)
    echo "Balance: $BALANCE wei"
fi

---

Next Steps

1. If .env doesn't exist: Create it with PRIVATE_KEY
2. If PRIVATE_KEY not set: Add it to .env or export it
3. Verify: Run verification commands above
4. Deploy: Run ./scripts/deploy-and-integrate-all.sh
