Discover all Ethereum addresses using your XPUB Master key

As a large book user, you are undoubtedly familiar with the management of your balance and Ethereum transactions. However, finding all the addresses associated with your account can be a tedious task, especially when you have access to your Master XPUB key. In this article, we will show you how to use your Master XPUB key to discover all Ethereum addresses linked to your wallet.

What is a XPUB key?

Before diving into the solution, let’s quickly review what an Xpub key is. An XPUB key is a public encryption key used by large book devices to sign transactions and messages. This key is essential to create and manage private keys to your big book equipment.

Why use your Master XPUB key?

Your Master XPUB key is safely stored on the Ledger device, which makes it accessible only. Using your Master XPUB key with other tools and software, such as this article, you can:

• Unlock encrypted data or transactions on the LEDGER application

• Generate new private keys for secure storage

• Create personalized scripts to automate tasks

Find all the Ethereum addresses using your XPUB Master key

Now that we have covered the basics of the XPUB keys and their importance, let’s dive into the way you can use your Master XPUB key to discover all the Ethereum addresses associated with your wallet.

Step 1: Open the LEDGER application

First of all, make sure that your big book application is updated and running. If this is not the case, open the application and access the “Settings” menu (represented by three horizontal lines at the top left).

Step 2: Access the “Portfuille” menu

In the Settings menu, select the “Wallet” option.

Step 3: Generate a new XPUB key

To find all the Ethereum addresses associated with your wallet, you will need to generate a new XPUB key. You can do it by:

• Click on “Generate a new XPUB”

• Selection of the address type (for example, address of the large book portfolio)

• Follow the prompts to create and record the new XPUB key

Step 4: Use your Master XPUB key with a script

To find all the Ethereum addresses, you will need to use your Master XPUB button with a script. Here is an example of how you can do this:

`Python

Import the necessary libraries

Import eth_abi like AB

Popen import sub-process

Define the contract address and Abi

contract_address = "0x ... your addition of contract ..."

abi = ab.abi_ffrom_paths (["path / to / abi.json"]))

Use your Master XPUB button to generate a new private key

Private_Key = Popen (['Ledger app', '-Getaddress', '--From', 'Master', 'Xpub'], Stdout = Popen ('-o', 'Script.txt')). Stdout.Read () .Decoder ()

Write the script in a file

With open ('script.txt', 'w') like f:

F.Write (private_key)

'

This script uses your Master XPUB button to generate a new private key and writes it in a file calledscript.txt. You can then use this file to sign transactions on the LEDGER application or another device.

Step 5: Use your new private key with the LEDGER application

To find all Ethereum addresses using your new private key, follow these steps:

• Open the LEDGER application

• Select the "Portfuille" option

• Click on "Use the key"

• Enter the file name (script.txt`) and select the correct address type (for example, address of the large book portfolio)

Conclusion

Using your Master XPUB key is a practical way to find all Ethereum addresses associated with your wallet. By following these steps, you can unlock encrypted data or transactions on the LEDGER application and generate new private keys for secure storage.

Do not forget to always keep your Master XPUB key safely, as anyone who has access to it can potentially compromise the safety of your wallet.
