Step 5: Environment Configuration

Create .env file in project root: # Required Configuration WEB3_PROVIDER_URL=https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID BACKUP_ENCRYPTION_KEY_FINGERPRINT=<generated-key> # Optional Configuration DATABASE_PATH=./secure_wallets.db LOG_LEVEL=INFO RATE_LIMIT_ENABLED=true MAX_REQUESTS_PER_MINUTE=2 MAX_REQUESTS_PER_HOUR=20 SESSION_TIMEOUT_MINUTES=15 Generate Backup Encryption Key: openssl rand -hex 32 # Copy output to BACKUP_ENCRYPTION_KEY_FINGERPRINT Get Infura Project ID: Sign up at https://infura.io/ Create new project Copy Project ID from dashboard Use in WEB3_PROVIDER_URL

Step 6: Verify Installation

python -c "from ultra_secure_wallet_v13_MAXIMUM_SECURITY import MaximumSecurityPaymentAPI; print('✅ Installation successful')"

Basic Usage Example

from ultra_secure_wallet_v13_MAXIMUM_SECURITY import MaximumSecurityPaymentAPI import getpass import os # Load environment variables from dotenv import load_dotenv load_dotenv() # Get master password securely (NEVER hardcode!) master_password = getpass.getpass("Enter master password: ") # Initialize API api = MaximumSecurityPaymentAPI(master_password) # Create new wallet wallet = api.create_wallet( wallet_id="my_ai_wallet", metadata={ "agent_name": "PaymentBot", "purpose": "automated_payments" } ) if wallet['success']: print(f"✅ Wallet created!") print(f" Address: {wallet['address']}") print(f" 📱 Setup 2FA with: {wallet['totp_uri']}") print(f" 🔑 Backup codes: {wallet['backup_codes']}") # CRITICAL: Save MFA secret and backup codes securely! # Store in password manager or encrypted vault # Check balance balance = api.get_balance("my_ai_wallet") print(f"💰 Balance: {balance['balance_eth']} ETH") # Send transaction (requires TOTP from authenticator app) totp_code = input("Enter 6-digit TOTP code: ") tx = api.send_transaction( wallet_id="my_ai_wallet", to_address="0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb", amount_eth=0.001, # Send 0.001 ETH totp_code=totp_code ) if tx['success']: print(f"✅ Transaction sent!") print(f" TX Hash: {tx['tx_hash']}") # Always cleanup sensitive data api.cleanup()

Command Line Demo

# Run built-in demo python ultra_secure_wallet_v13_MAXIMUM_SECURITY.py # Follow prompts: # 1. Enter strong master password (20+ chars) # 2. System creates demo wallet # 3. Displays active security features # 4. Shows wallet address and 2FA setup

Password Requirements

• The system enforces strict password policies:
• # Minimum requirements
• Length: 20+ characters
• Uppercase letters: 1+
• Lowercase letters: 1+
• Digits: 1+
• Special characters: 1+
• Entropy: 80+ bits
• Recommended Password Generation:
• # Generate strong password
• openssl rand -base64 32
• # Or use password manager:
• # - 1Password
• # - Bitwarden
• # - LastPass
• # - KeePassXC

Two-Factor Authentication Setup

After creating a wallet, you'll receive: TOTP Secret - Store in password manager QR Code URI - Scan with authenticator app Backup Codes - Save offline securely Compatible Authenticator Apps: Google Authenticator Authy Microsoft Authenticator 1Password (has built-in TOTP)

Rate Limiting Configuration

Edit in code or environment: # Default limits MAX_REQUESTS_PER_MINUTE = 2 # Per wallet/IP MAX_REQUESTS_PER_HOUR = 20 # Per wallet/IP LOCKOUT_DURATION = 3600 # 1 hour in seconds

Audit Logging

All operations are logged to secure_wallet.log: # View logs tail -f secure_wallet.log # Filter for specific wallet grep "my_ai_wallet" secure_wallet.log # Check for security events grep -E "SECURITY|ERROR|FAILED" secure_wallet.log

Using with AI Agents

class PaymentAgent: def __init__(self, master_password): self.wallet_api = MaximumSecurityPaymentAPI(master_password) self.wallet_id = "agent_wallet" async def process_payment(self, recipient, amount, totp): """Process automated payment""" # Check balance first balance = self.wallet_api.get_balance(self.wallet_id) if balance['balance_eth'] < amount: return {"error": "Insufficient funds"} # Execute transaction result = self.wallet_api.send_transaction( wallet_id=self.wallet_id, to_address=recipient, amount_eth=amount, totp_code=totp ) return result def cleanup(self): self.wallet_api.cleanup()

Environment-Specific Configuration

Development/Testnet: # Use Sepolia testnet WEB3_PROVIDER_URL=https://sepolia.infura.io/v3/YOUR_PROJECT_ID # Or Goerli WEB3_PROVIDER_URL=https://goerli.infura.io/v3/YOUR_PROJECT_ID Production/Mainnet: # Ethereum mainnet WEB3_PROVIDER_URL=https://mainnet.infura.io/v3/YOUR_PROJECT_ID # Enable all security features RATE_LIMIT_ENABLED=true REQUIRE_2FA=true AUDIT_LOGGING=true

Backup and Recovery

Export Wallet Backup: # Encrypted backup creation api.export_wallet_backup("my_wallet", backup_password="strong-backup-pwd") # Creates: wallet_backup_20240215_123456.enc Restore from Backup: # Import encrypted backup api.import_wallet_backup( "wallet_backup_20240215_123456.enc", backup_password="strong-backup-pwd" )

Test on Testnet First

Never test with real ETH on mainnet! # 1. Get testnet ETH # Visit: https://sepoliafaucet.com/ # Enter your wallet address # Receive free test ETH # 2. Configure testnet export WEB3_PROVIDER_URL=https://sepolia.infura.io/v3/YOUR_PROJECT_ID # 3. Run tests python ultra_secure_wallet_v13_MAXIMUM_SECURITY.py

Unit Testing

# Install test dependencies pip install pytest pytest-cov pytest-mock # Run tests (if available) pytest tests/ # With coverage pytest --cov=ultra_secure_wallet_v13_MAXIMUM_SECURITY tests/

Common Issues

Problem: "ModuleNotFoundError: No module named 'pysqlcipher3'" # Solution: Install system dependencies first sudo apt-get install libsqlcipher-dev pip install pysqlcipher3 Problem: "Web3 provider not connected" # Solution: Check Infura URL and API key echo $WEB3_PROVIDER_URL # Should output: https://mainnet.infura.io/v3/YOUR_PROJECT_ID Problem: "Argon2 too slow / system freeze" # Solution: Reduce Argon2 parameters in code # Edit MaxSecurityConfig: ARGON2_MEMORY_MB = 128 # Reduce from 512 ARGON2_ITERATIONS = 4 # Reduce from 16 Problem: "Rate limit exceeded" # Solution: Wait for cooldown or increase limits # Limits reset after 1 hour # Or edit rate limit config
