But why create an NFT?
Having the soul of a digital artist, wanting to protect the intellectual property of their work or earning income from the sale of their works are three of the main reasons for creating an NFT.
An item is fungible when it can be exchanged for other equivalents. For example, a $10 bill can be exchanged for two $5 bills or 10 $1 bills. Instead, NFTs are single items, so there will only be one – or a limited number – of them.
The simplest way to apprehend them is to consider them as if they were trading cards, paintings, works of art or films with the particularity that they are autographed. This is what gives it its unique and exclusive particularity.
The “autograph”, the “seal of authenticity” or token is contained in the blockchain (block chain) of the platform on which it was created. So, although there are millions of copies on the web, only one has the seal of authenticity.
The token it also represents ownership and allows objects to be traced, much like the certificate of authenticity for works of art.
But one of the most powerful aspects is that the creator of the NFT receives income each time the token change ownership, within the framework of the fees that are established at the time of its preparation.
What do you need to create an NFT
Although there are several alternatives for converting a digital object into a token non-fungible, and you can even make them yourself, the easiest and most convenient way is to use some of the established platforms.
The reason? They are faster for the seller and give more visibility to the objects. On the buyer side, they are more reliable than independent platforms, given the many scams that exist around cryptocurrencies.
Most major platforms transact with Ether (ETH), the cryptocurrency of the Ethereum blockchain. In this way, if you want to start creating your own NFTs, you must have the following items.
How to create your NFT
Although most platforms offer the ability to create your own token non-expendable, we will cover the process to achieve it in OpenSea. This platform is considered as the leading NFT marketplace, but also does not charge any additional fees for minting your token.
Step 1: create your collection
From your Opensea.io account, go to your profile icon and click on the button Create, located in the upper right corner.
Step 2: upload your file
On the next page, you will need to upload the digital file you want to convert to NFT. You should assign a name, description, and external link to the artwork so that potential buyers know more about the object.
You can upload image files, videos, 3D models, music files or any other digital content. Accepted formats include JPG, PNG, GIF, SVG, MP4, WEBM, MP3, WAV, OGG, GLB, and GLTF.
Although the maximum file size is 100MB, the platform recommends uploading files smaller than 40MB to speed up the downloading process.
Step 3 – Customize your NFT
After filling in these fields, you will be able to customize your NFT, for example by placing it in an existing collection or adding properties, levels, stats or unlockable content.
In this section you will also be able to define the number of units of the object that you can hit, although at the moment OpenSea only allows the creation of a single file.
Another option is to choose in which block chain you want to hit your NFT. Although the most recommended network is Ethereum, it is also compatible with Polygon (Matic) and Klatyn (Klay)
When you’re done, hit the Create button and you’re done. You will now be able to sell your NFT.
How to sell your NFT
NFTs on Ethereum are based on open source standards and are held by you in your wallet. That way, when you hit an NFT, you’re not tied to any platform, so you can create them on OpenSea and sell them on Mint or Foundation, for example.
If you want to sell it on OpenSea, you must do the following:
- From your Opensea.io account, select your profile picture and click on Profile.
- Select the NFT you wish to sell.
- Select Sale top right.
- On the next page you should set a price and define the type of sale: fixed price or scheduled auction.
- You can also define a duration (1 or 3 days or 1 week), although you can also customize it with the calendar.
- If you wish, you can reserve the item for a specific buyer. Simply paste their email address in the field Reservation for a specific buyer.
In all the options, you will see the sale prices at the bottom: a service charge 2.5% OpenSea and creator’s royalty (10% is the maximum offered by OpenSea).
Please note that if you did not mint the item on OpenSea, you will need additional approval and signature before the platform will allow the item to be sold under your name.
You will then need to confirm your sale by signing a transaction. And that’s all. You will now be able to sell your first NFT.
