Running Electrum console commands outside of Electrum on Linux
Electrum is a popular Python library for interacting with the Ethereum blockchain. If you have an Electrum console command configured outside of Electrum, you can use it in your Python application to retrieve wallet balances and other information.
Prerequisites:
- Electrum must be installed on your system.
- To save your Electrum settings, you need to create a configuration file (e.g. “config.json”). This file should contain:
– “Password”: Your Electrum password
– “server_url”: The URL of the Electrum console command (e.g. “
– “rpc_version”: The RPC version you want to use (default 4)
- You need to configure the Electrum console command to work on your system.
- You need to install the
subprocessesmodule 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 called “config.json” in the same directory as your Electrum console command script (e.g. “getbalance.py”). This file should contain:
json
{
“password”: “YOUR_ELECTRUM_PASSWORD”,
“server_url”: “
“rpc_version”: 4
}
Replace "YOUR_ELECTRUM_PASSWORD" with your Electrum password.
Step 2. Install the subprocess moduleYou need to install the "subprocess" module in Python. Run the following command:
Oh no
pip install subprocess
Step 3. Configure Electrum console commandsTo configure Electrum console commands, you can use a script or a separate Python process that starts the Electrum wallet and then exits. Here are two examples.
1. example: using a separate process
Create a new file called "getbalance.sh" in the same directory as your Python application:
Oh, no
#!/bin/bash
Set Electrum settings
password = “YOUR_ELECTRUM_PASSWORD”
server_url=”
Run Electrum wallet and get balance
getbalance=$(./run-electrum.sh “$password” “$server_url”)
echo “Wallet account balance: $getbalance”
Create a new file called run-electrum.sh in the same directory:
Oh, no
#!/bin/bash
Set Electrum settings
password = “YOUR_ELECTRUM_PASSWORD”
Run Electrum wallet and get balance
getbalance=$(./getbalance.sh “$password”)
echo “Wallet account balance: $getbalance”
Run "run-electrum.sh" to start the Electrum process, then run the Python app:
Oh, no
python getbalance.py
2. example: using a single process
Create a new file called "getbalance.py" with the following content:
python
import subprocess
password = “YOUR_ELECTRUM_PASSWORD”
server_url=”
Start Electrum wallet and get balance
subprocess.run([./run-electrum.sh”, “$password”, “$server_url”], check=True, stdout=subprocess.PIPE)
getbalance = subprocess.check_output(“getbalance”.split(), stdin=subprocess.PIPE).decode()
print(“Wallet balance:”, get balance)
Run "getbalance.py" to start Electrum process and get wallet balance:
Oh no
python getbalance.py
Calling the function "getbalance()"
To call the function "getbalance()" outside of Electrum, you can use the following Python code:
python
import subprocess
password = “YOUR_ELECTRUM_PASSWORD”
server_url=”
Get balance using getbalance
subprocess.run([./getbalance.sh”, “$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 Options
- You can modify the “config.json” file to use different settings for Electrum console commands.
