Completed Code

Follow the completed code all the way through.

This section demonstrates how to attach License Terms to an IP Asset. By attaching terms, users can publicly mint License Tokens (the on-chain “license”) with those terms from the IP.

​
Prerequisites

There are a few steps you have to complete before you can start the tutorial.

  1. Complete the Setup Your Own Project
  2. Create License Terms and have a licenseTermsId. You can do that by following the previous page.

​
Attach License Terms

Now that we have created terms and have the associated licenseTermsId, we can attach them to an existing IP Asset.

Let’s create a test file under test/2_AttachTerms.t.sol to see it work and verify the results:

Contract Addresses

We have filled in the addresses from the Story contracts for you. However you can also find the addresses for them here: Deployed Smart Contracts

​
Test Your Code!

Run forge build. If everything is successful, the command should successfully compile.

Now run the test by executing the following command:

forge test --fork-url https://aeneid.storyrpc.io/ --match-path test/2_AttachTerms.t.sol

​
Mint a License

Congratulations, you attached terms to an IPA!

Completed Code

Follow the completed code all the way through.

Now that we have attached License Terms to our IP, the next step is minting a License Token, which we’ll go over on the next page.
