Mainnet checklist

Latest software

Please check that you are running the latest stable Nimbus software release.

Note: If you are setting up your client before launch, it is your responsibility to check for any new software releases in the run up to launch. At the minimum you should check the release page weekly.

More than 50 peers

Please check that your node has at least 50 peers. To monitor your peer count, pay attention to the Slot start messages in your logs.

Validator attached

Please check that your validator is attached to your node.


Now that you have Nimbus up and running, we recommend setting up a systemd service with an autorestart on boot (should you experience an unexpected power outage, this will ensure your validator restarts correctly).

Systemd will also ensure your validator keeps running when you exit your ssh session (Ctrl-C) and/or switch off your laptop.

For the details on how to do this, see this page.

Ethereum Foundation's Checklist

Ad a final check, we recommend you also go through the EF'S staker checklist.
