Backup your Art Blocks

If you are a savvy NFT collector you are already aware that the actual visual content is not stored on the blockchain. This means that you will loose the content of your token as soon as third party hosting the file goes out of business. The only question is “when”.

To prevent the loss of the data we advise every collector to store their own tokens’ data. Below we’ll show you how to find the data of an Art Blocks NFT.

1. Navigate to your token’s page at OpenSea

2. Scroll to the details section

You will see a Token ID field (highlighted yellow in this screenshot). Click on the right hand side of it (282000866) — it’s a link to this token’s metadata, e.g. https://token.artblocks.io/282000866.

3. Locate the artwork address

At the link you will see the token’s metadata (JSON) similar to the text shown below. Locate “image” and “generator_url” fields.

Save this metadata to a file on your laptop (e.g. 282000866.json).

  "description": "Memories of Qilin is inspired by traditional East Asian art. It channels the sense of movement and fluidity found in classical Chinese brushwork, while drawing from the colors, patterns, and forms of ukiyo-e woodblock prints. \n\nThe series explores elements of folklore, evoking the mythological imagery of dragons, phoenixes, flowers, and mountains.  The title references a fabled chimerical beast found throughout East Asian mythology (while the qilin is its Chinese name, it is also known in Korea as the girin and Japan as the kirin) that represents prosperity and luck.\n\nViewers are invited to interpret elusive forms that verge on representation. As with the stories passed on through generations, each piece is imagined, organic, and ever-in-flux.",

4. Open both “image” and “generator_url” in separate browser tabs.

Now you can simply save both of those to a safe place on your laptop by pressing Cmd+S (or via File -> Save Page As). Note that the “generator” is the most important part that actually renders the artwork from scratch — without it you will be limited to the pre-rendered “image” resolution (which is of poor image quality).

5. Check that your local artwork works

Navigate your browser to the downloaded artwork, e.g. file:///Users/alex/Downloads/282000866.html
