The metadata checker is a check up for the correctness of your metadata
With the Metadata Check you can check if the metadata of an asset is aligned with the CIP-0025 Metadata Standard and if it contains any incorrect characters or values.
The Metadata Check will now respond with a notfication message or an error message
However, for now, this Metadata-Check does not check if your asset_name is matching the tokenname in NMKR Studio. So please make sure to always use the <asset_name> placeholder in your metadata to not cause any issues with that.
