ERC-721 or NFT tokens is a standard for non-fungible tokens (NFT) or deeds. NFT are useful to represent digital or physical assets that cannot be divided
Each NFT Collection Smart Contract you create represents:
A Standard ERC-721
Standard NFT based on OpenZeppelin implementation
A container of NFT items
Each minted NFT item is stored inside the NFT Collection
A Marketplace
You can put up for sale or at auction your NFT Items
Your NFT Collection token is fully compatible with the ERC-721 Standard
Features
Ownable
Only one account can own a NFT at a time
Transferable
Your token can be transferred directly or by approval
Metadata
Your token smart contract is identified by a symbol and a name
Token URI
Each minted NFT has a single tokenURI, which is a URL that stores the media and all the attributes of its unique NFT.
Enumerable
The smart contract counts and list valid NFTs assigned to an owner
Mintable
Authorized users can mint new NFTs
Buy & Sell
Owners can sell their NFTs and any user can buy
Auctions
Owners can auction their NTFs by setting a minimum reserve amount, and any user can auction. The contract works like a scrow that allows funds to be stored safely until the auction ends

Symbol and Name
Just like ERC-20 has a symbol and names, ERC-721 tokens also have a symbol and a name. This symbol and name is a one-time setting, cannot be changed after deployment.
Sales and auctions commissions
Commission that you will receive from Sales and Auctions. 0 means no commission, 100 means 100% of the sale as commission. Commission has to be a number between 0 and 100. This can be changed dinamically after deployment.
Wallet
Ethereum address or EVM compatible wallet address to receive funds. This is the beneficiary account that will receive the Marketplace commissions in Ether, BNB, xDai or Matic. This can be changed dinamically after deployment.
Now you can deploy to your desired network
Options
Who can mint?
This is a smart contract setup. If anyone can mint it means that anyone can create a NFT item on your Marketplace. Otherwise, only the contract owner can mint new NFT items.
What user roles can create NFT items on your Marketplace?
This is a WordPress level configuration. Choose the WP user roles authorized to create NFT elements, both in the Backend and the Frontend of your site.
All users can edit all NFTs
This is a frontend setting to allow all creators to modify the data for all items. By default, NFT items can be modified by their authors, but if you want all authors to be able to modify all NFT elements, activate this option. (Not recommended)
Show OpenSea link
If your contract is deployed to Ethereum mainnet or Polygon mainnet, an auto-generated link to OpenSea will be displayed in the item view
Use pixelated images
By default, each browser will render images using aliasing to a scaled image in order to prevent distortion. Check this if you want the image to preserve its original pixelated form. This is usefull if your items are icon-like images
Examples of pixelated and atialiased images
Enable Sub-Collections?
By default, galleries are not enabled, you can enabled them selecting one of two choices
Your galleries will be show on the top as a dropdown list
