_It’s super important to make your own crypto wallet instead of using someone else’s because your wallet is literally where your crypto keys live. Here’s why it matters:_

### 1️⃣ **You control your private keys**

*   Your private key is the “master key” to your crypto.
    
*   Whoever holds the private key can **spend your crypto**.
    
*   If you use an exchange or a third-party wallet, **they control the keys**, not you.
    
*   Famous saying in crypto:
    

**“Not your keys, not your coins.”**

### 1️⃣ Install Python

*   Make sure you have **Python 3.x** installed.
    
*   Check by running in Command Prompt / Terminal:
    
        python --version
        
    
    If not installed, download it here: [https://www.python.org/downloads/](https://www.python.org/downloads/)
    
*   **2️⃣ Install required library**
    
    Open your terminal/command prompt and run:
    

This installs the library to generate 12-word phrases.

### 3️⃣ Create the Python file

1.  Open **Notepad** (or VSCode/Notepad++).
    
2.  Paste this entire code into it:
    
        from mnemonic import Mnemonic
        
        mnemo = Mnemonic("english")
        
        wallets = []
        
        for i in range(1000):  # generate 1000 wallets
            seed_phrase = mnemo.generate(strength=128)  # 12 words = 128 bits entropy
            wallets.append(seed_phrase)
        
        # Save to a file
        with open("wallets_1000.txt", "w") as f:
            for idx, phrase in enumerate(wallets):
                f.write(f"Wallet {idx+1}: {phrase}\n")
        
        print("1000 wallets with 12-word phrases generated successfully!")
        
    
    Save the file as `generate_wallets.py`
    
    1️⃣ Open Command PromptPress **Windows + R**, type `cmd`, and hit Enter.
    
    ### 2️⃣ Navigate to the Desktop folder
    
        cd C:\Users\pappu\OneDrive\Desktop
        
    
    _Use your file path_
    
    3️⃣ Run the script
    
        python generate_wallets.py
        
    
    After a few seconds, you should see:
    
        1000 wallets with 12-word phrases generated successfully!
        
    
    ⚠️ Reminder: Keep wallets\_1000.txt safe. Anyone with this file can access all the wallets.
