Pre-Generated and 1/1 Collections

We'll show you to use the Bueno generator if you've already created your finished token artwork.

Creating a pre-generated or 1/1 tokenset costs the same amount as creating a tokenset with our art generator.

If you already have your art files generated, or are creating a collection made up of entirely 1/1 custom tokens, you can still use Bueno to generate your collection and deploy your contract.

Before you start, consolidate all of your artwork & metadata into a single folder. Your folder should look something like this:

📁 Folder






Alternatively, you can upload a single JSON or CSV file that contains all of the token metadata (alongside your images). Examples are attached below.


Once your files are organized in a folder, you can create your new collection by following these steps:

1. Click the Generative Collection button.

2. Choose the option I already have my own artwork.

3. Enter a name for your collection and click create.

4. Click Upload Files and then drop in your folder.

5. Check the preview to make sure your tokens look correct. If you have token metadata, then click on the tokens to preview the attributes. Here, you can also choose whether or not to maintain your current token order.

6. Click upload!

Note: Uploading can take a long time if you have a lot of files.

Once uploaded, you can view your tokens in the preview tab.

When you’re ready to generate, follow these steps as normal.

Custom Upload FAQ

I don’t have the metadata now. Can I add it later?

If you don't have your metadata prepared, you can manually edit the metadata for each token. This can be managed in the Custom Tokens section of your collection.

How many tokens can I upload?

20k is currently the maximum amount you can upload into Bueno.

What is the file limit?

The file limit is 30Mb per token. If you need more, please contact support.

What file types are supported?

The custom uploader supports the same file formats as the normal uploader - JPEG, PNG, GIF, APNG and SVG.

Can I keep my tokens in order?

Yes! If you upload a metadata CSV then you’ll have the option to maintain the order. Otherwise, you can manually set the number for each token after upload.

My upload is taking a long time/failing. What can I do?

Try uploading your tokens in smaller batches. If the problem persists, please contact support.
