3.1 Scope​

If you create a Derivative Work and engage in Triggering Distribution, you must publicly release that Derivative Work under this same license.

3.2 Definitions​

"Derivative Work" means any modification, enhancement, or work based on the software that:

  • Alters, adds, or removes functionality of the original code
  • Incorporates substantial portions of the original source code
  • Creates new components that depend on or interface with the original software

Derivative Work does NOT include:

  • Configuration files or parameters
  • Plugins or extensions that use only public APIs
  • Works that merely link to or use the software as a library without modification

"Triggering Distribution" means:

  • Making the Derivative Work available to any third party (whether by download, hosting, or other means)
  • Using the Derivative Work to provide services accessible to third parties
  • Deploying the Derivative Work in production environments accessible to others

3.3 Publication Requirements​

Within 90 days of first Triggering Distribution, you must:

  1. Publish source code on a publicly accessible platform (e.g., GitHub, GitLab, Codeberg)
  2. Include this license with the published code
  3. Provide clear attribution identifying:
    • The original work (EVVM)
    • MATE Labs Inc. as the original licensor
    • A description of your modifications
  4. Ensure accessibility - the code must remain publicly available for at least 3 years

3.4 Internal Use Exception​

You are NOT required to publish Derivative Works that:

  • Remain internal to your organization
  • Are not distributed to third parties
  • Are not used to provide services to external users

However, once you engage in Triggering Distribution, the 90-day publication requirement begins.
