Specify the Tokens Metadata to replace the placeholders in the Metadata Template
Metadata Structure
It is critical that your metadata adheres to the same structure as your template, which conforms to the Cardano CIP-0025 Metadata standard. This is also the structure of the Metadata Template for your project. NMKR Studio is build that way that you specify a Metadata Template and just give the Tokens specific Values with the Metadata of the token. If you haven't specified that, please do that before continuing with the Tokens unique Metadata.
