Series flow

Learn about launching a Series on Highlight

The Series flow lets you launch collections where the artwork and metadata for each token is unique. This includes PFP projects.

Drop a series collection

Head over to Highlight and click the "Create" button at the top. Click on "Create a collection" in the top right hand corner and select "Series" from the dropdown.

Upload your artwork & metadata

The Series flow will require you to zip your files for upload.

Important notes on your zip file:

  • If you are deploying a random mint series collection, the .zip file should be 3.5GB or less

  • If you are deploying a collector's choice series collection, the .zip file should be 30MB or less

  • File names should not contain any spaces

The .zip file should contain:

  1. The folder named images should hold the artwork for each token. Supported file formats are as follows:

    • Image: PNG, JPG, GIF, WEBP

    • Video: MP4, WEBM

    • Audio: MP3, WAV

  2. A .json file named metadata.json

    • The metadata.json file should contain an array of objects, where each object represents a token. Each token object should contain the following entries:

      • "metadataId": An integer that identifies this token. Metadata IDs must start at 1 and be sequential. Note that a token with a given metadata ID may have a different token ID when it is minted if you have a random mint mechanic in place (see the price and distribution step for details).

      • "imageRef": The name of the image asset to use for the token (for example: "image-1.png")

      • "animationRef": The name of the animation asset to use for the token (for example: "animation-1.mp4"). This entry is optional and only necessary if you want to use a separate animation asset.

      • "name": The name of the token. This will appear as the tokenโ€™s name on marketplaces.

      • "description": The description of the token. This will appear as the tokenโ€™s description on marketplaces, and is distinct from your collection's description (specified in the collection details step).

      • You may add additional entries that specify any custom traits for this token, for example:

        • "Background Color": "Red"

        • "Height": 7.2

        • "Shiny": false

        • Note: there is a maximum of 100 unique traits. Series data can be reviewed once uploaded.

  3. Optional: A folder named "animations" (only necessary if your series uses .gif, .mp4, .webm, or .webp files for animations). This folder contains any animation assets used by your tokens. We currently support .gif, .mp4, and .webm files for animations.

    • Note: animated collections require an image file for each token.

Easy ways to build your metadata.json file

If youโ€™re not sure how to create your metadata.json file, you can easily convert a .csv spreadsheet (which you can export from Excel, Google Sheets, etc.) to .json format using this tool.

Highlight Studio also offers a metadata building tool in the tab โ€œSeries Metadata.โ€ This tool allows you to navigate to a directory on your local machine, generating a metadata.json file for the images (and/or animations) within that folder. If a metadata.json file already exists, Studio helps you easily modify and validate it.

Please note that this functionality is currently exclusive to Chrome, leveraging its Filesystem API for seamless access to local files. See Highlight Studio for more details.

Use the following example to ensure that your files are in the correct formats:

10MB
highlight-example-project.zip
archive

Preview your drop

After uploading your artwork, preview the tokens to ensure that your artwork and metadata have been uploaded correctly.

Collection details

Enter the details of your collection in the following steps. Note that you don't have to wait for the artwork to upload to enter in the collection details.

Series details

  1. Set the specific blockchain your collection will launch on.

  2. Input your collection name and description.

  3. Name your contract and add a collection logo image. This image does not represent an actual token, but serves to show collectors an example of what they'll get and appears on third-party sites.

  4. Toggle for transferability, which makes your collection "soul bound". This means the NFT cannot be traded or exchanged but is instead tied to the collector's wallet address.

Mint details

  1. Enter the price of your token. Don't worry, you can change this later from the token management page.

  2. Enter the mint start and end date. This can also be updated on the token management page.

  3. Choose your mint style. Collector's choice means the collector can view all the different artwork and pick one to mint. A random mint means that token artwork will be revealed randomly after minting.

  4. Apply a gate to your collection. This can also be changed post collection deployment so that different collectors can access your mint at different points.

  5. Input your primary and royalty payout addresses.

  6. Specify the number of mints per wallet.

Review and deploy

Review and deploy your collection once all the details have been set and finalized.
