I can help you with that. Here is 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 must have a Bitcoin-QT node set up and running.

• You must 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:

”just like that

bitcoin-qt-rpc –list-wallets

This will list all the wallets available on your node, including those with empty wallets. Note the URL of the wallet you want to extract data from.

Getting a confirmation number



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

python

import requirements

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

url = “wss://localhost:8532/QRL-MAIN-SLOT”

Set the transaction ID

tx_id = 1234567890

Set the query parameter for the number of confirmations

query = f”?confirmed={int(tx_id)}/”

Send a GET request to the QRpc API with query parameters

response = requests.get(url + request)

Check if the response was successful

if response.status_code == 200:

Parse the JSON response

data = response.json()

Print the transaction confirmation number

print(data[“result”][“confirmed”])

else:

print(“Error:”, response.text)

“

In this example, we send a GET request to the QRpc API with theconfirmedquery parameter set to the transaction ID. We then parse the JSON response and print the number of transaction confirmations.

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

• You can use thebitcoin-qt-rpc` package’s built-in query parameter parser to handle different query parameter formats.

• If you need to retrieve information from an empty wallet, you may want to check if the wallet has any pending transactions before attempting to retrieve the confirmation number.

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