Mint NFT eBook

Mint NFT eBook with LikeCoin NFT Book Press
Mint NFT requires the Keplr Browser Extension and LikeCoin on a desktop computer
Publishing an NFT eBook on the blockchain involves the following processes:

Create an epub file and enter metadata

Create an ePub file and enter metadata. First, create the ePub file for the e-book, and ensure that the metadata has been entered and organized. Metadata includes book title, author, cover image, publication date, description, etc. Taking the commonly used ePub editing software as an example:

calibre

In calibre, the "Edit Metadata" button is in the upper left corner of the screen. After organizing the metadata, click "Save to disk".

Click "OK" after edited metadata

Sigil

In Sigil, you can press the F8 key to edit metadata on the fly.

After preparing the ePub file, register it as an ISCN.

Click on the URLs to check whether the content has been successfully uploaded.

Note that the '/1' in the picture is the ISCN version number, which is not essential when creating NFT eBooks.

List the Book for Sale

Listing for sale is divided into two steps: minting the NFT eBook and listing it. An analogy to traditional publishing is printing manuscripts into books and placing them on bookshelves for sale.

In the "Enter ISCN ID or NFT Class ID" field, enter the ISCN ID
If you forget your ISCN ID, you can retrieve it in "My Works" at app.like.co.
The system will automatically extract the basic information of ISCN for you. Fill in other information required in the "By filling required information" tab.
Enter the number of NFTs to mint in the "Number of NFT to mint" field.
If your book file is in ePub format, the system will automatically extract the link to the AR cover and place it in the "Image URL" column.
"External URL (optional)" and "URI (optional)" do not need to be filled in.
After filling in and confirming that everything is correct, click "Mint". The Keplr wallet will pop up windows several times. Click "Approve" to sign.
Enter all the information and click "Mint"
