Melts is the product that allows downloading the End Users (Fluid Attacks customers) code repositories and a few other utilities that End Users (Fluid Attacks hackers) require now and then like checking if a group is active, if it has Forces, its language, among other functions.

Using Melts

  1. Make sure you have the following tools installed in your system:

  2. Make sure you have an API token from the ARM, and that you put its value in an environment variable named INTEGRATES_API_TOKEN.

    You can export this variable permanently by adding the following line at the end of your shell startup file (usually ~/.bashrc):

    export INTEGRATES_API_TOKEN="your-integrates-api-token"

    Now close the terminal and open it again, or run:

    $ source ~/.bashrc
  3. Now you can use melts by calling:

    $ m gitlab:fluidattacks/universe@trunk /common/melts

    Feel free to pass the --help flag to learn more about the things it can do for you.

  4. Code repositories in a given group can be downloaded by executing:

    $ m gitlab:fluidattacks/universe@trunk /common/melts pull-repos --group {group_name}

    To download a specific code repository, it can be done by passing an additional argument:

    $ m gitlab:fluidattacks/universe@trunk /common/melts pull-repos --group {group_name} --root {nickname}


In case you encounter any errors while using Melts, there are a couple of things you can try to fix them:

  • The first thing you should do is follow the installation instructions again.
  • The next thing you can check is if your INTEGRATES_API_TOKEN hasn't expired, for this you only need to repeat the steps shown here for updating your API token, and be aware of when it will expire next.
  • Another thing that may be causing issues is a conflict in your environment variables that are taken when you log into AWS, so you can try deleting this information and logging in again. In order to do this use the command rm -rf ~/.aws/credentials before logging in, if that doesn't work then use rm -rf ~/.okta* as well. After doing this and logging in with the appropriate credentials and choosing the correct role, if applicable, you should have solved any problems regarding permissions.
  • If none of these work, get in contact with the Fluid Attacks team sending an e-mail to [email protected] to assist you with any problems.


  1. Melts is a CLI written in Python. It communicates with the Integrates API and reports stability problems in the source code to Bugsnag.
  2. Melts is distributed to the End Users using Makes.

Development Environment

Follow the steps in the Development Environment section of our documentation.

When prompted for an AWS role, choose dev, and when prompted for a Development Environment, pick melts.
