Thank you for testing

With Medalla testnet coming to a close, the cloud beacon for this project has been shut down. You can, of course, use this general idea with a beacon of your own.

Voluntary exit from Medalla testnet

This project provides a workflow to exit validators that were created by eth2.0-deposit-cli from Medalla testnet, using your keystore-m JSON files and your password. All secrets are kept local on your machine. A cloud-located beacon node is used to deliver the exit message, although you can configure the project to use your own beacon.

The project assumes that you accept Prysm's TOS. If you object to their TOS, please do not use this project.

Prerequisites

This project has been tested on Linux, and should work on MacOS and Windows 10.

Linux

You need git, docker, and docker-compose. Assuming Ubuntu:

sudo apt update && sudo apt install -y git docker docker-compose

MacOS

You will need Docker Desktop and Git.

Windows 10

You will need Docker Desktop, Git, Python 3, and WSL 2. WSL 2 and Python 3 can be installed from the Microsoft Store.

Use

Clone the project

Assuming that the project will go into your home directory:

cd ~; git clone https://github.com/eth2-educators/medalla-exit.git; cd medalla-exit

Optional: Adjust variables

The file .env contains the location of the cloud beacon node. If you'd rather provide your own Prysm beacon node, edit that file.

The project assumes the node is providing a secure connection. If yours does not, edit .eth2/process-exit.sh and remove the --tls-cert parameter.

Copy keys to be exited

Copy keys of validators that you wish to exit into .eth2/validator_keys. This project supports keys created by eth2.0-deposit-cli, they will have a name that starts with keystore-m and ends in .json.

If your keys do NOT all have the same password, you may want to do this in batches. This project assumes that all keys in .eth2/validator_keys have the same password.

Run the exit procedure

Run sudo docker-compose run validator-voluntary-exit. This will import your keys and then exit your validators. Prysm will prompt you to navigate to a web site and input a phrase that confirms that you understand that this process cannot be reversed.

• When asked for a wallet directory, accept the default
• When asked for a wallet password, choose any you like. It will be used during voluntary exit, and then never again.
• Provide the password for the keystore file(s).

This project does not store a wallet after it completes, all wallet files are destroyed after successful exit
