Project Information
This guide covers all of the information relating to the Project Information settings on your project.
Note - many of the parameters you set in the project information directly influence your project and how it will be minted. Please read this section carefully.

Project Name

This is the name internal to NMKR Studio that describes the NFT project/policy. It's required and must be between 3 and 30 characters. It is available to be minted in the metadata by using the <series_name> placeholder if desired.

Project URL

You can associate a URL with each NFT Project as a way to track where it is being sold. This URL is not used anywhere outside of NMKR Studio and is optional.


A short summary of the entire NFT Project. It's available to be minted in the metadata via the<series_description> placeholder. It has a maximum of 100 characters and is optional.

TokenName Prefix

If you want each NFT that's minted under this NFT Project to have a certain number of characters added to the beginning of the NFT's name you can use this option. It has a maximum of 15 characters and is optional.

Address Reservation Time

This controls how long an NFT is reserved for once it's been claimed by a potential buyer. The values range from 10 minutes to 60 minutes, in 10-minute increments.
The default is 20 minutes which gives the buyer plenty of time to purchase but doesn't hold the NFT under reservation for too long.
Note - this includes the time taken for the transaction to reach the NMKR Studio Cardano Wallets, not just for the user to press send. Recently, the Cardano Blockchain has had little congestion so this is becoming less of an issue.
If you have a project that experiences a high volume of potential buyers in a brief window of time then it may be better to have a lower the Address Reservation Time. This ensures that if all NFTs are reserved that they won't sit around for a while before becoming available for purchase again.
If your project doesn't have a large number of buyers at once or there is congestion on the blockchain, then you can use a larger Address Reservation Time window so your customers have a longer period to complete the transaction.

This setting is not applicable when using the Single Pay-In Address.
You can change the Address Reservation Time after the NFT Project is created.

Max NFT Supply

Note - the default is set to 1 and this is the setting you should use if you are an NFT project. Any number above 1 will technically be a Fungible Token.
This represents the number of times each NFT that you upload under the NFT Project can be minted. This typically is set to 1 to make sure the NFT is truly individually unique.
Alternatively, if you want (for example 10) exact copies (fungible tokens) of each unique CNFT you can set this number to 10 and that will allow 10 copies of your unique NFT to be minted.
To do this, locate the NFT Projects tab on the Dashboard (Step 1) and within that section you need to click on "Create New Project" (Step 2) where you can set the token supply for each new NFT (Step 3).

Payout Wallet

You should set this to be one of the wallets you linked as part of the Payout Wallets preparation phase.
Each NFT Project must be associated with a single wallet to send the ADA generated from your NFT sales. We always recommend to add your external ADA wallet before you launch your project. However, you can change the Payout Wallet after the NFT Project is created.

Send back to Customer

TLDR: leave it on the default (2 ADA every NFT and communicate this to your customers)
This option allows you to customise the amount of ADA that is sent back to your customers as part of the minting process.
Current Options
Default Option Selected
Without going into too much detail on this, Cardano requires a minimum amount of ADA to be sent with any transaction, having NFTs in a transaction increases this amount slightly, resulting in roughly 2 ADA needing to be sent along with any NFT. (If you are really interested in the specifics on this, look into the EUTXO Model, specifically the MinUtxo mechanics.
Anyway, for the purpose of your project, you have 3 options:
  • 2 ADA every NFT
    • This is the default and will send back 2 ADA for every NFT that your customer mints.
    • Make this clear to your customers
  • 2 ADA every 5 NFTs
    • This will send back 2 ADA for every 5 NFTs (or less)
    • For example:
    • 3 NFTs would send back 2 ADA 8 NFTs would send back 4 ADA 11 NFTs would send back 6 ADA 16 NFTs would send back 8 ADA
    • Make this clear to your customers
  • MinUtxo
    • This is the most optimal method, that will send the absolute minimum amount of ADA back to your customers, based on the number minted in the transaction.
    • Because this amount will vary depending on various factors it is not possible to put an act amount in this tutorial.
    • But, roughly speaking it will be slightly more efficient than the 2 ADA every 5 NFTs option.
    • However, this comes at the cost of being more difficult to communicate to your customers.

Allow Cross Sales

This feature gives you control over if you would like to have the option for customers to add NMKR Token to their NFT Purchases. This is set as Active by default and only applies to the Payment Gateway.
Allow Cross Sales Activated
For the end user, the Payment Gateway will then either have (or not have) this option:
