Basic Examples (13) 

Set the default blockchain to the Cardano testnet:

Create an image:

Get your keys and address:

You need some tADA (the Cardano cryptocurrency) in your address to send transactions. To achieve this, you will use a Cardano Testnet Faucet. This is a website that will send some amount of tADA to your address.

To use it, copy your address to the clipboard and visit the Cardano Testnet Faucet:

In[5]:=

In[6]:=

Paste your address in the Address field (double-check that your address is complete and does not have extra characters such as double quotes). Make sure both the Environment "Preprod Testnet" and the Action "Receive test ADA" are selected in the drop-down menus. Click the "I'm not a robot" captcha and then the Request funds button:

Once you request funds, it may take about a minute for the transaction to be added to the blockchain.

Once the transaction has been added to the blockchain, check your address balance (and other details) with the BlockchainAddressData function by running this line:

In[7]:=

Out[7]=

If this line returns an error, that means the transaction has not been added to the blockchain yet. Wait a moment, then try running the line of code again. You will see here the details of your address, including your balance (given in Lovelace units). If you just want to extract your balance, you can evaluate the following:

Mint the NFT:

Get the data of the transaction that minted the NFT. It may take some time for the transaction to be added to the blockchain:

Scope (3) 

Use a File as the NFT source or thumbnail.

Set the default blockchain to the Cardano testnet:

In[18]:=

Out[18]=

Get your cryptographic keys and blockchain address. For this example, you will need key pairs with an associated balance of at least 1850000 lovelace (see first example on this page for creating and funding a key pair):

In[19]:=

Out[19]=

Export an image and JSON file to use them in the NFT:

Mint the NFT and specify the thumbnail and source using File:

In[24]:=

Download the files linked to the NFT:

In[25]:=

Out[25]=

You have to wait around 20 seconds (up to about two minutes) for the transaction to be added to a block, so if you run this right away you will most probably get an error:

In[26]:=

Out[26]=

Once the transaction is added to the blockchain, save the transaction data:

Recover IPFS content identifiers for the certificate thumbnail and data from the Metadata property of the transaction:

You can mint multiple NFTs in one single transaction and assign them to different owners.

Set the default blockchain to the Cardano testnet:

Copy your cryptographic keys from above. For this example, you will need key pairs with an associated balance of at least 5295701 lovelace (see first example on this page for creating and funding a key pair):

Create the metadata for three NFTs. Start by producing three images:

In[36]:=

And assign to them different properties and owners:

You can use a wallet like Nami Wallet to hold and visualize your NFT:

If you already have the associated files stored in an external storage system, you can provide custom URIs with the "Thumbnail" and "Source" keys. MintNFT will not try to determine the format of the file in this case so you also need to provide the MIME types using "ThumbnailMIMEType" and "SourceMIMEType" keys:
