Step by step to create and sell NFT

Step by step to create and sell NFT . 

It is possible to generate this type of token at no cost and in a few steps. You need to enter a platform, create an account and use a digital wallet

It is known as NFT as any digital element (photo, video, text, etc.) hosted in blockchain technology or block network, which grants a certificate of authenticity to the hosted product.

It should be remembered that NFT is the acronym for non-fungible token. The latter means that it is something unique and as such, unrepeatable. If, for example, the NFT of a photo is created. That particular NFT is unique because it has a seal of authenticity, a unique identification on the blockchain. Eventually, digital copies of that photo could be made, for example, through screenshots, but these copies will not be NFT and will not have that seal of authenticity.

Soul of Stinus, the soul of the 21-year-old who sold himself as an NFT

By way of comparison, it is the same difference that there can be between an original painting by Picasso that bears his signature and the millions of reproductions that can be made that are just that: copies, which were not created by the author and do not have his stamp. Here, the seal is given by the blockchain.

NFTs can be created from photos, videos and other content

What is the use of creating an NFT? In the first place, it serves to learn to know a little more about the technology that continues to advance . In fact, Instagram recently announced that it will allow users to share NFTs on their profiles and stories. In January, Twitter enabled this option , albeit in a limited way, for users of its premium service, Blue .

On the other hand, it can be a way to generate money, since once the NFT is created it can be auctioned and obtain cryptocurrencies . This can be a good form of income for content creators of all kinds, including artists such as musicians, photographers, or video editors, among many other options.

How to create your own NFT

The first step to create an NFT is to generate a user on a platform for this purpose. One of the most used is OpenSea, which in addition to allowing the digital token to be generated, works as a market place where the product can be auctioned.

OpenSea allows NFT to be generated and marketed

Upon entering OpenSea , the site will request that a digital wallet be added . In case you do not have an account on such a platform, then you can select one of the options listed on the site. Metamask is usually recommended , which is one of the best known and easiest to use. It has a version for Chrome, Firefox, iOS and Android.

When the wallet is configured, a password will be added, as in any other account, and in addition, a 12-word recovery phrase will be automatically generated . Those terms are what is known as a seed phrase and it is a way of supporting the digital wallet. They must be stored very well since if at any time the password is forgotten or for whatever reason access needs to be recovered, those 12 words will need to be entered in the order received.

Connect with a digital wallet

Once this is done, click on the Create option within Open Sea and proceed to fill out the form that will appear below. The first step is to upload the file that you want to “mint” or convert into NFT.

Upload the file you want to minte

In the case of OpenSea it can be an image, audio, video or 3D model . In the event that you want to mint a tweet, then you can use the Valuables platform, which is specifically for that purpose.

Once the content has been uploaded, it has to be given a name and a collection must be created in which that material and others that you want to add will be.

The system will request to add a description of the element, properties (there is a dropdown menu to add options), and to include a reference page of the user who is creating the NFT.

You are then asked to choose a block network in which the token will be generated . The first option that appears is Ethereum but if this alternative is selected, you will have to have a balance in crypto to pay what is known as the gas fee, which is the cost involved in uploading that file to the blockchain and may vary. depending on network congestion. The value ranges from 70 USD.

To generate the NFT without that cost, you have to select the Polygon network, a protocol that works through a sidechain or lateral chain that connects to Ethereum , with the benefit that it allows you to save on gas fees and offers greater processing.

Once the network is selected, you have to sign the creation, following the steps on the screen and at the end , the NFT will have been generated. To market it you have to press the button that says "sell" (sell) in the upper right margin.

Then you must choose a time during which it will be auctioned and the value it will have. When it is carried out, OpenSea will keep a 2.5% commission.

Once the NFT has been created to sell it, you have to press the button that says "sell" in the upper right margin

How to Configure Metamask for Matic (Polygon)

In case Polygon has been chosen as the blockchain, when putting the item up for sale you will need to add that network to the Metamask wallet.

To carry out this operation, you have to click on the fox icon, in the case of being in the browser or, enter the app from the mobile. Then you must enter the icon that is in the upper right margin, at the height of the image of the fox and press there.

Enter Settings to add the network

A menu will be displayed. Go to Settings , press that option and then enter Networks .

Choose Networks

Within networks, press the option that says Add network.

Then go to Add network

Then a menu will be displayed to manually enter the network data. These data are published on the official Polygon Mainnet site and can be found here .

The data entered in the official Polygon site must be entered

There you will find the data of the network name, the URL address, the string identifier, etc. It is important to take into account that you must enter what appears on the official site mentioned above and not information that comes from another way because, as the warning on the screen indicates, it could be erroneous information with the aim of redirecting content or funds to another account .

At the end of the process, the item will look like this

At the end of this process, you can proceed to sign, as indicated on the screen and that is the final step of the NFT sale process.
