This Python script monitors the Ethereum blockchain for new finalized blocks and sends email notifications when a block is proposed by a validator index specified in the validators.txt file. I should mention that I run this instead of using beaconcha.in service as the app will send a notification even if it's at odd hours of the day (and I don't want to silence it as I want to be pinged when validators are down). This is therefore a homebrew solution to receive email when one of my validators proposes a block.
-
Clone the repository or download the script files.
-
Install the required Python packages:
pip install requests python-dotenv -
Create a
.envfile in the same directory as the script and provide the following information:

[email protected]
PASSWORD=smtppassword
SMTP_SERVER=smtp.changethis.com
SMTP_PORT=587
-
Replace the placeholders with your actual email credentials and SMTP server details.
-
Create a
validators.txtfile and list the validator indices you want to monitor, one per line. For example:
1
2
3
To start monitoring the Ethereum blockchain and receive email notifications, run the script:
python scan.py
The script will continuously check for new finalized blocks. When a block is proposed by a validator index listed in the validators.txt file, an email notification will be sent to the specified receiver email address.
The email notification includes the following information:
- Proposer index
- Block number
- MEV reward (in ETH)
- Block reward (in ETH)
