What’s art? Probably anything a single person can appreciate as art. NFTs are a great tool for selling unique digital content, specially the ones that can’t be easily duplicated and have some collectible value that will potentially increase over time. Private and retail investors are already buying and selling NFTs for profit, for example this blueish guy with pipe was sold by more than 7.5 millions of dollars few weeks ago. “Everydays: The First 5000 Days” image from the digital artist Beeple was sold for $69.3 million, making it the third highest-valued artwork ever sold by a living artist. And you thought the sneakers collectible market was crazy.
To be fair NFTs digital art pieces are not just images, music or video for watching in a computer. there are unbreakable contract that gives you the ownership of the unique digital content that you can sell or transfer to another person. So for me it’s totally legit if anybody wants to pay 50 millions dollars for a contract he would sell few moths later for 120 million dollars (by the way this has been the business of many art traders and collectors for the last century or so).

Unless you are the new digital Banksy (like Beeple) in order to sell your art you will need a NFT marketplace. This is basically the digital version of the traditional art gallery where your pieces will be showcased and they will facilitate the selling transaction for a finder’s fee. Again there are several choices for Ethereum based NFTs, but for this guide I will recommend you to use nftgamef.com. It is probably one of the biggest NFT marketplaces available that is already handling a great volume in NFT transactions. Most importantly it is extremely easy to create, setup and list your digital content into NFTs ready to sell.
The first step will be to sign-in using your configured MetaMask wallet. There’s no real registration step, OpenSea will ask you to anonymously identify yourself with a confirmed wallet:
Furthermore is highly recommended to confirm your email address and complete your personal profile.
The next step will be to create a Collection. A collection in OpenSea is a set of different NFTs related in some way to each other. Creating the first token in a collection will have some cost associated but not for the next ones. Let’s remind one NFT is a unique (however the token could be also mintable into multiple copies of itself) piece of content we want to publish in the blockchain and potentially sell in the marketplace.
For this article I created a collection in OpenSea named Led Matrix Art, I will add to this collection some pieces of pixel art specially designed to be visualized in a RGB led matrix display.
In the Create menu go to My Collections:
Choose to create a new collection and input some basic information like name, description and logo image:
Because you are not putting anything yet in the blockchain you will be able to easily edit these details later without doing any transaction at all. A collection is basically a way for OpenSea to group content into token contracts and for users to browse sets of tokens.
There are some extra options you can change per collection before uploading any content than can be useful to explore. Specifically in the Commission section you can set a percentage fee you will collect any time any NFT in this collection will be sold. Not just the first time you sell it but every time somebody sell it forever:
Now we are ready to actually submit our digital content into the blockchain and create an NFT you can sell. Inside your collection click into Create new item to upload your digital content and provide some information about it. OpenSea currently supports only few formats to cover most of the media types for your digital content:
– Images/animation: JPG, PNG, GIF, SVG– Audio: MP3, WAV, OGG– Video: MP4, WEBM– 3D models: GLB, GLTF
For this article I’ve chosen to add my own pixel/led art interpretation of the infamous Stonks’s mememan as a NFT inside the Led Matrix Art collection:
One interesting feature of the listing is you can add several fields and properties attached to the content. This can be useful to provide some insight or metadata for the content that will be included as well inside the token contract. In my case I want to add some physical properties like height and width in pixels/leds:
Another option is to include some unlockable content that will be visible only to the owner. This can be useful to provide a simple proof of ownership, a private link to download extra content or maybe a secret message from the author, possibilities are endless (and time is limited). In our case I want to include a private url with instructions for the owner to setup his own RGB led matrix to show the digital art at home:
After hitting the Create button your digital content will be converted into a smart contract and send to the blockchain for free.
Congratulations!You have successfully created your first item inside a collection in OpenSea!The next step will be actually listing the NFT for sale.
