Examples quickstart: create a Living Asset

In this page we explain how to use a simple script from our examples repository.

To follow this example you will need to have installed on your development machine:

  • NodeJS
  • GraphQLPlayground or any similar GraphQL IDE
  • The details for the Freeverse Universe already created for you by our onboarding team, along with the GraphQL endpoint URL - contact us if you do not yet have a universe.


As instructed in the Github Readme, after cloning into the project run

cd nodejs && npm ci

to setup the environment and install all relevant packages.

Creating an Asset

Navigate to the file nodejs/asset_create.js; open it and edit the first three variables to the your universe owner credentials (private key, public address, universe id)


Feel free to modify the asset properties and metadata below, as you see fit, then save the file.

From a terminal, navigate to the nodejs folder and run

node asset_create.js

The command will output a GraphQL mutation with the signed query, in the correct format, to the terminal.


Sending the mutation

You may use any method to send this mutation to our GraphQL endpoint; though in this example we are using GraphQL playground. Open the editor and point it to the url provided. Paste the mutation directly into the left-hand panel of the ID and press the middle play button to send it. In the right-hand panel, you will see the ID of the newly created asset.
