Metadata

The beauty of an NFT lays in the metadata. Without it, an NFT is just a native token that doesn't look like anything. The metadata of an asset is attached with the label 721 to the transaction in which the NFT is minted as described in CIP 25.

Best Practices

• When adding links make sure to include the https:// prefix. This makes your link clickable in most cases.

• Pay attention to nice and consistent formatting. Should be obvious, but instead of naming your attribute blue_background_0_1, name it Blue Background.

Updating Metadata

It is possible to update the metadata of an NFT as long as the policy is not locked. According to the standard, only the metadata contained in the latest mint transaction shall be considered as valid. This means that the metadata can be updated by minting and burning another copy of the asset.
