How does the marketplace work?

The marketplace brings together businesses, developers, and asset providers in a mutually beneficial platform. Users do business through a simple three-step process:

  • Step One:

    An Asset Provider publishes a service offer with accompanying contract agreements to a registry. After a reviewing process, the service offer will appear on the Public Offer Catalog.

  • Step Two:

    Businesses discover Assets in the public offer catalog that meet their unique needs.

  • Step Three:

    Businesses follow an on-boarding process, accept the terms and conditions, and begin using the asset in their projects. They immediately have the tooling and SDKs to build, test, and deploy the applications.
