Claiming Royalty

Let's say you have a parent IP Asset that specifies in its License Terms that any derivatives must share 10% of their revenue with it. A child IPA then agrees to those, mints a License Token, and registers as a derivative.

In the below example, we will see how the parent IPA can claim its due 10% revenue from a child IPA that earns revenue.

Prerequisites

  • Understand the 💸 Royalty Module
  • A child IPA and a parent IPA, for which their license terms have a commercial revenue share to make this example work
