💬Discourse Plugin

A Discourse plugin to enable Sign-In with Ethereum as an authentication method.


Discourse is an open-source discussion platform used for most crypto governances and projects to discuss proposals, updates, and research. The following is a quick guide on how to add Sign-In with Ethereum to your existing Discourse.


This guide is currently compatible with Discourse's official distribution. The discussion about these issues with other builds can be followed here.

The Sign-In with Ethereum plugin still requires users to enter an email to associate with their accounts after authenticating for the first time. If the user owns an ENS address, it will be the default selected username. Once an email address is associated, users can then sign in using the SIWE option at any time.

Enabling the Plugin

To install and enable the plugin on your self-hosted Discourse use the following method:

  • Access your container’s app.yml file (present in /var/discourse/containers/)

cd /var/discourse
nano containers/app.yml
  • Add the plugin’s repository URL to your container’s app.yml file:

  before_code:                             # <-- added
    - exec:                                # <-- added
        cmd:                               # <-- added
          - gem install rubyzip            # <-- added
    - exec:
      cd: $home/plugins
        - sudo -E -u discourse git clone https://github.com/discourse/docker_manager.git
        - sudo -E -u discourse git clone https://github.com/spruceid/discourse-siwe-auth.git   # <-- added
  • Follow the existing format of the docker_manager.git line; if it does not contain sudo -E -u discourse then insert - git clone https://github.com/spruceid/discourse-siwe-auth.git.

  • Rebuild the container:

cd /var/discourse
./launcher rebuild app

To disable it either remove the plugin or uncheck discourse siwe enabled at (Admin Settings -> Plugins -> discourse-siwe -> discourse siwe enabled ).

Create a Project ID

This plugin uses the newest Web3Modal v2, in order to use it you need to create a free project id at https://cloud.walletconnect.com/sign-in and configure it in the plugin.

Edit the message statement

By default a statement is added to the messages: Sign-in to Discourse via Ethereum. To edit this statement access the settings (same as before) and update it.
