🚀 Quick Start Guide

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

🔒 Security Configuration

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:

1. TOTP Secret - Store in password manager
2. QR Code URI - Scan with authenticator app
3. 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

🎓 Advanced Usage

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

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"
)

🐛 Troubleshooting

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
