Running Electrum Console Commands Outside Electrum on Linux
Electrum is a popular Python library for interacting with the Ethereum blockchain. If you have an Electrum console command set up outside of Electrum, you can use it from your Python application to get wallet balances and other information.
Prerequisites:
- You need to install Electrum on your system.
- You need to create a configuration file (e.g.
config.json
) to store your Electrum settings. This file should contain the following:
– password
: Your Electrum password
– server_url
: The URL of your Electrum console command (e.g.
-rpc_version: The RPC version you want to use (default is 4)
- You need to set up the Electrum console command to run on your system.
- You need to install thesubprocess
module in Python, which allows you to create new processes and interact with their output.
Step by Step Instructions:
Step 1: Create a Configuration File
Create a file calledconfig.jsonin the same directory as your Electrum console command script (e.g.
getbalance.py). This file should contain the following:
{
"password": "YOUR_ELECTRUM_PASSWORD",
"server_url": "
"rpc_version": 4
}
Replace YOUR_ELECTRUM_PASSWORD'' with your Electrum password.
Step 2: Install thesubprocessmodule
In Python, you need to install thesubprocessmodule. Run the following command:
pip install subprocess
Step 3: Set the Electrum Console Command
To set the Electrum Console command, you can use a script or a separate Python process that starts your Electrum wallet and then exits. Here are two examples:
Example 1: Using a separate process
Create a new file called getbalance.sh
in the same directory as your Python application:
#!/bin/bash
Configure Electrum settings
password="YOUR_ELECTRONIC_PASSWORD"
server_url="
Start Electrum wallet and balance
getbalance=$(./run-electrum.sh "$password" "$server_url")
echo "Wallet balance: $getbalance"
Create a new file called run-electrum.sh
in the same directory:
#!/bin/bash
Configure Electrum settings
password="YOUR_ELECTRONIC_PASSWORD"
Start Electrum wallet and balance
getbalance=$(./getbalance.sh "$password")
echo "Wallet balance: $getbalance"
Run run-electrum.sh
to start the Electrum process, then run the Python application:
python getbalance.py
Example 2: Using a single process
Create a new file called getbalance.py
with the following content:
import subprocess
password="YOUR_ELECTRONIC_PASSWORD"
server_url="
Start Electrum wallet and balance
subprocess.run([./run-electrum.sh", "$password", "$server_url"], check=True, stdout=subprocess.PIPE)
getbalance = subprocess.check_output("getbalance".split(), stdin=subprocess.PIPE).decode()
print("Wallet Balance:", getbalance)
Run getbalance.py
to start the Electrum process and get the wallet balance:
python getbalance.py
Calling the getbalance()
function
You can use the following Python code to call the getbalance()
function from outside Electrum:
import subprocess
password="YOUR_ELECTRUM_PASSWORD"
server_url="
Get the balance using the getbalance functionsubprocess.run([./getbalance.sh", "$password", "$server_url"], check=True, stdout=subprocess.PIPE)
balance = subprocess.check_output("getbalance".split(), stdin=subprocess.PIPE).decode()
print(balance)
Replace `YOUR_ELECTRUM_PASSWORD'' with your Electrum password.
Tips and Variations
- You can edit theconfig.json` file to use different settings for the Electrum console command.
