I can help you with that. Here’s a step-by-step guide on how to retrieve the number of confirmed transactions from a Bitcoin-QT (Bitcoin-Qt) node with an empty wallet using the QRpc API:

Prerequisites

• You need to have a Bitcoin-QT node set up and running.

• You need to install the bitcoin-qt-rpc package in your project. If you don’t have it installed, you can do so by running pip install bitcoin-qt-rpc (on Linux/Mac) or conda install -c conda-forge bitcoin-qt-rpc (on Windows).

Getting the QRpc API URL

To connect to the QRpc API, you need to get its URL. You can do this by running the following command:

bitcoin-qt-rpc --list-wallets

This will list all available wallets on your node, including those with empty wallets. Take note of the URL for the wallet you want to retrieve information from.

Retrieving Confirmation Count

Once you have the QRpc API URL, you can use it to retrieve the confirmation count of a specific transaction. Here is an example:

import requests











Set the QRpc API URL and the ID of the wallet you want to retrieve information from

url = "wss://localhost:8532/QRL-MAIN-SLOT"



Set the transaction ID

tx_id = 1234567890



Set the confirmation count query parameter

query = f"?confirmed={int(tx_id)}/"



Send a GET request to the QRpc API with the query parameters

response = requests.get(url + query)



Check if the response was successful

if response.code_status == 200:

    
Parse the JSON response

    data = response.json()


    
Print the confirmation count of the transaction

    print(data["result"]["confirmed"])

else:

    print("Error:", response.text)

In this example, we send a GET request to the QRpc API with a query parameter confirmed set to the ID of the transaction. We then parse the JSON response and print the confirmation count of the transaction.

Tips and Variations

• You can modify the query variable to include other parameters, such as the block number or hash.

• You can use the bitcoin-qt-rpc package’s built-in query parameter parser to handle different formats for the query parameters.

• If you need to retrieve information from a wallet with an empty wallet, you may want to check if the wallet has any pending transactions before trying to retrieve its confirmation count.

Hope this helps! Let me know if you have any questions or if there’s anything else I can help with.
