#### Sample JSON Metadata File

See below for a sample JSON file.  Note that the `721` and Policy ID wrappers are generated on the fly, so they should not be included in the uploaded file.

```
{
  "WildTangz 1": {
    "mediaType": "image/png",
    "project": "Wild Tangz",
    "fur": "Crimson",
    "body": "Default",
    "accessories": "None",
    "eyes": "Crying",
    "eyewear": "Monocle",
    "headwear": "Beret",
    "clothing": "Overalls",
    "mouth": "Cigarette",
    "name": "WildTangz 1",
    "background": "Carmine Pink",
    "image": "ipfs://QmdsAtotMCHAAPZEiw66H6kbDGpoEwy4pn4XTq6CbZQo5t"
  }
}
```

Each file should have exactly one asset in it.
