Step by Step Workflow
This guide is designed for those in our community who have very little programming knowledge. Using this step-by-step process, you will be able to create and Mint your NFT project.
The aim of this guide is to provide you with the optimal workflow for getting your project live, using our most up to date systems to ensure the best user experience.
In every NFT drop, there are 5 high level tasks that need to be completed to ensure everything is technically ready for launch.
  • NMKR Studio Settings
  • NMKR Studio Config
  • Upload Base Media (The Art)
  • Upload Metadata
  • User Minting Frontend (Website)
This section is designed to be a very quick overview that will likely save you considerable time and effort when getting your project ready.

NMKR Studio Settings

It is logically helpful to think about the NMKR Studio side in two parts, the first of which is settings and this covers all of the simple backend tasks such as:
These tasks don't take very long and are very simple to do using our user interface but they should remain in your mind throughout the project and should not be left until the 'last minute'.

NMKR Studio Config


The second part of NMKR Studio will be the more technically complex elements that need to be considered ahead of time to ensure the smoothest possible set up. This is specifically referring to the POLICY ID LOCKING and of course, the Metadata Template.
Correctly configuring the metadata is an important part of constructing your NFTs on the Cardano blockchain. Most projects currently use this as a place to describe the asset such as the serial number, what hat the character is wearing and how many attributes it has.
It is very important to think about the metadata you want to have well in advance so that you can align your art design, your source attribute files and your metadata template.
Think about:
  • What are the variables in my art? For example:
    • Do they have hats, backgrounds, items, glasses, haircuts?
    • Is it a video, a song and so on.
  • How granular do I want to be? For example:
    • One attribute for the 'background' like 'gradient-red'
    • Two attributes like 'bgstyle' = 'gradient', 'bgcolour' = 'red'
  • Do I want the website/twitter/discord links in the metadata permanently?
Note - each metadata attribute has a maximum limit of 64 Characters

Policy ID

The Policy ID is what identifies the unique collection of NFTs. As such this is something very important and you want to make sure that your community are made aware of the REAL Policy ID.
In terms of config, there really is only one thing to do here and that is to decide when the Policy ID locks. Having a locking policy date means that after that date, not further NFTs can be minted or edited in anyway under that Policy ID. In short - no further changes can be made and those assets will remain on the chain forever.
People expect Policies to close at some point in the near future (less than a year) for several reasons, with the main one being that they know that once the policy locks, the supply of the NFTs is locked and thus their value wont be diluted by a rouge project who mints more.
Note that the locking date can never be edited once set up, so think carefully about how long you need to mint your collection.
Note - We highly recommend implementing a locking date on your project Policy ID

Upload Media

Once you have your art completed, you need to upload it to our servers so that it can remain there, ready to be minted. There are several ways that this can be done, with the best being via the SFTP Server but the API is available for those who prefer this.

Supported File Types

You can all upload additional subfiles for ***, such as:
Application: Zip; PDF; Json; GITF+Json, Octet-Stream
Audio: Mpeg; Ogg; WAV.
Image: Bmp; SVG+XML.
Text: HTML; Javascript; Plain Text; CSS.
Video: Mpeg; Mp4; Ogg; Quicktime; Webm.
Further information can be found in the Uploading Files section.

Upload via our SFTP-Server

The best method of uploading your files is through our SFTP-Server (see guide). This allows you to upload, in bulk without needing to write code or use the API.

Upload Metadata

If you plan on using the SFTP server, this next part is essentially the same process of drag-and-drop, only using the .metadata JSON files rather than the .PNG Image files or other media you might have already uploaded.
Having already completed the NFT-MAKER Metadata Config, you will already have the template and placeholders ready to accept the Metdata and as such can start to upload this.

Minting Frontend

This final, very important step is all about how your community will actually mint your NFT's. We have made this very easy with various options for how this can be done, with the most recommended being to use our Payment Gateway on your website. The Payment Gateway provides by far the best end-user experience with a clean, professional interface that seamlessly integrates with the users wallet. If you don't plan on having a website, you can also use our single-pay in address as did many projects in the early months of NFTs on Cardano.

Final Thoughts

As a final headline overview, try and build your project in a way that means you can try things out with one or two files first, check it and then implement the bulk operations.
You may also want to use our Testnet to try things out first before you launch your project.
