NFT Build Tutorial; How To Sell Our Unique Tokens?

Everywhere there is talk of NFTs, or unparalleled tokens; Rare assets that are created and transferred on the Chinese block. NFTs have come as a surprise to many; A simple digital image sells for over $ 100,000. 

On the other hand, we hear that someone is willing to spend tens of thousands of dollars for a football player token, which has no special use. If you are wondering what exactly NFT building means, how you can work in this field and make and sell your tokens, read this article to the end.

In this article, I do not intend to discuss the nature and value of NFTs, and I will try to explain how to enter and work in the field of NFTs. However, first I will give a brief explanation of what NFT is and what its advantages are.

What is NFT?

Non-fungible token, or NFT for short, is a unique digital asset. Unlike Bitcoin, Atrium, and other digital currencies that are replicable and have interchangeable units, each NFT unit has specific features that set it apart from other units.

Although NFT‌s seem to be a new innovation, if we pay a little more attention, we are not strangers to them.

The price of a professional football shoe may not even reach 20 million Tomans, but if the same shoe was the foot of Ali Karimi, the legend of Iranian football, and he scored an important national goal with it, how much can it be worth?

How much will a postage stamp that can be bought today for less than 5,000 Tomans be worth if it belongs to the period of Naser al-Din Shah Qajar and it turns out that Amir Kabir signed it?

Allegorical tokens are valued in much the same way and with their own characteristics, except that these tokens are virtual and you can not touch them.

Stamp BagheriBagheri stamp; Related to the Qajar period

An NFT, similar to digital currencies (Bitcoin, Atrium, etc.), is stored and transferred, except that each unit of proxy tokens has its own unique characteristics and is not of the same value as the other units.

Digital currencies are money, or at least their purpose is to be money. This means that digital currencies must not only act as a store of value, an exchange medium, and a unit of calculation, but must also be fungible . Therefore (if the conditions are normal) the value of one bitcoin is equal to another bitcoin, just as a thousand toman banknote is not different in value from another thousand toman banknote. When you lend a thousand toman bill to your friend, you do not expect to get back exactly the same bill.

But NFTs are an exception to the latter rule; That is, in the normal case, one unit of a non-allegorical token cannot be equated with another unit of a non-allegorical token; Just as it is not possible to borrow one person’s car and then hand over another car to him.

The main thing that makes an NFT different from other digital assets (such as a regular file or a diamond in a computer game) is that its ownership is registered on a blockchain (an immutable database) and no one can infringe on that ownership. .

 Also, as I mentioned, NFTs are stored in the owner’s wallet like digital currencies (like tokens) and can be transferred in a few seconds with a simple transaction. In other words, with the help of NFTs, there is no need to go through time-consuming processes to transfer ownership (sale) of a digital asset.

The work sold as NFT for more than $ 69 million. Called “Every Day: The First 5000 Days” and created by Beeple, it contains 5,000 digital images created by the artist over the past 13 years. The original quality file is also donated to the owner.
Today, although there are still technical and legal challenges (ownership and copyright) to NFTs, a painting, a photo, an in-game item, a video, an Internet domain, a ticket, and NFT can be made.

In order not to deviate from the purpose of the article, it is enough to explain about NFTs so far. If you want to know more about them, read the article «What is NFT?»I suggest you.

 Also, if you do not understand why someone would be willing to pay thousands of dollars for NFT for an easily downloadable image, read the article «The subject of NFTs»I suggest.

I go to the main point. How to build and sell your NFT?

What do we need to get into NFT?

What is needed before attempting to work with NFTs depends on the platform and the type of NFT, but on almost all platforms two things are required:

1. Wallet (Metamsk)






NFT exchanges will be done through users’ wallets. Simply put, when you buy or build an NFT, that NFT is stored in your wallet. So you need to have a digital wallet to work with sites in this field.

Most NFT projects on the network today Atrium They work and the best Atrium wallet for interacting with decentralized programs, free wallet MetamaskIs. This wallet is installed as an add-on on Chrome and Firefox browsers and you can safely use it to exchange Atrium and tokens based on it. So for the first step, download the Metamsk wallet for your browser and create an Atrium account on it. FromThis link You can download this software.

Be sure to write down the backup words that the program gives you at the beginning of the wallet. If the software is deleted from the browser, you can only access your property again with that backup.

In the future, NFT platforms may operate on other blockchains such as Binance chain and Theron, so you need to get the right wallets for these chains. Wallets that you can use are usually listed on each NFT site.

2. Some digital currency (usually ether) to pay fees and charges







To build NFT you have to pay two main costs: platform fee and network fee .

The amount of the platform fee depends on the site you are using to build NFT, and the network fee also depends on the status of the network on which the NFT platform operates.

Unfortunately, Atrium Network fees are very high at the moment due to network congestion, and a large part of the cost is the same fees. Fees will be much lower on platforms built on other blockchains such as China Bainance.

Remember that creating a unique token does not mean selling it, and the cost of building NFT will not be reimbursed.

Two ways of operating in the NFT space

Nft activity

There are two general ways to work directly in the NFT field:

  • Build NFT on specific platforms and sell it on NFT exchange sites
  • Buy ready-made tokens from NFT exchange sites and sell them at a higher price (NFTs deal)

Each of these two methods has its own challenges.

For example, if you choose the first method, you may need expertise, reputation, skills and marketing experience to be able to build an NFT that someone is willing to buy, and in the second method, you have to invest a lot and with this Be familiar with the market so you can identify which NFT will be valuable in the future.

In the first method, the risk is usually less, because you only pay for the platform and fees and build your NFT in the hope of selling it, but in the second method, because you buy a token at a high price, there is no guarantee that someone is present. Be able to buy it from you again.

There are different types of proverbial tokens and they are classified into different categories.

 So to build an NFT, you must first know its types to know which type is most suitable for your situation. For example, one common type of NFT is to convert a work of art or history (painting, photo, document) into a token and sell it, but if you are not a celebrity, this method may not be right for you.

 In the following, you will get acquainted with the most important types of NFT‌.

Important : The digital currency team does not endorse or guarantee any of the following platforms, and the digital currency website has no recommendations for entering this field. General and technical review of these platforms is the responsibility of the user.

Build a simple NFT; Digital artwork

The most pervasive type of NFT‌ at the present time (early 2021) is digital art, or digital art. The general idea is simple: convert a PNG, JPG, MP4, Gif, and فایل file to NFT, and you can sell it if you wish.

Of course, if you are not a celebrity or your NFT is simple and unattractive, you should not expect anyone to be willing to spend their valuable money on your NFT.

Popular art NFTs are usually made either by a well-known artist or by specializing in programming and Smart contract It is used in them.

The good news is that if you are not familiar with programming, you can build NFT on many platforms with just a few clicks.

Here are some of the biggest websites where you can build NFT digital art:

Each of these sites has its own characteristics and rules. For example, in Mikersplus, people must have an invitation from other artists to build NFT, or prove that they are an artist by filling out a form, but on open and rebellious platforms, anyone can build their own NFT.

In this section, I will teach you how to build NFT on an OpenSite site, because according to our research, the easiest way to build and sell NFT right now is through this site.

Of course, before an NFT-building website was created, OpenShop was a platform for buying and selling NFTs, and not very suitable for building complex and transformative NFTs. You can try other websites to create more professional NFTs.

Learn how to make NFT digital art on the OpenSite site

1. Go to the official Opensea website at and click on the “Create” button at the top of the page.

NFT Construction Tutorial (1)

2. Click on the “Sign In” button to connect your Metamsk wallet (which you have already installed on the browser) to the extension. This does not require a fee.

5. Now your collection is ready and you can add any file you like by clicking on “Add New Item”. Your collection can only contain one file. In the Add Item section, you can upload the original file that you want to NFT.

NFT Construction Training (5)

As defined above, we define each part of this section:

  1. In this field, you must enter the name of the desired item. If you only NFT an item, you can enter the same name as your collection.
  2. You will see the link of the NFT page on the OpenSite site after construction.
  3. In this section you can write a short description for your item.
  4. If your NFT has a special feature (for example, it has a picture of a man in it) you can add your desired feature to it. This section is not required.
  5. If your NFT has numeric properties (such as speed), you can add the feature you want to display as a progress bar. This section is not required.
  6. If your NFT has numeric attributes (such as speed), you can add the attribute you want to display it in mode. This section is not required.
  7. By activating the “Unlockable Content” check box, the file is only displayed when NFT is purchased, and in fact only the token owner can view it.

6. After adding at least one item, you can create your NFT and put it up for sale by hitting the “Sell” button.

The pricing process is up to you. You can set a fixed price for your NFT (1 in the image below) and you can also choose to have NFT sell at the highest bid after a while. (2) It is also possible to combine an NFT with other NFTs for sale. (3) The currency is on the Atrium Open platform, but you can choose other currencies as well.

After selecting how to sell by clicking the “Post Your Listing” button, the Metamsk wallet will open and ask you to make a transaction on the Atrium network to put the token for sale. At this stage, you have to pay the Atrium network fee that Metamsk has set for you, which at the time of writing this article is relatively high due to network congestion.

Finish: Metamsk asks you to make a transaction.

Digital cards and collectible games

When I was less than eight years old, “playing cards” were popular among children. In the streets and neighborhoods of Iran, children played with paper cards and tried to get more cards in any way possible; Especially football cards.

Card GameNostalgia: Football Cards – Image by Essam

These cards had no use other than games, but among the children, whoever had more cards saw one head and neck higher than the others and could have a better chance of winning the next games.

Some cards were more valuable than others because of their scarcity; I remember very well that I was not willing to exchange a special card of David Beckham with even two hundred other cards. If you have also experienced playing cards, congratulations, you are already familiar with the phenomenon of unparalleled assets.

Now these same cards have entered the digital world and instead of being physical and put in our pockets, they are digital and we store them in a digital wallet. We also play on our computers and mobile phones instead of playing them in the street.

In the world of NFTs, each digital card is a token whose ownership is registered on the Chinese blockchain, and the holder can store it in their personal wallet (such as an Atrium wallet) and easily transfer or sell it.

Digital cards that convert to NFT are commonly used in games, so whoever has more and better cards will have a better chance than others. 

How each card works and how it becomes valuable depends on the game.

For example, in a football game, Ronaldo’s card is more valuable than the card of an average player, because whoever has a Ronaldo card, will naturally have a better chance of winning and gaining points.

One of the spaces that can make the most of NFTs is the multibillion-dollar gaming industry. It is no exaggeration to say that in the not too distant future, in computer games, game items will be presented in the form of tokens to give real ownership to players and to be able to sell them for real money outside of the game. 

For example, imagine that the famous Clash of Clans game is a token and everyone can sell it for real money if needed.

There are currently many Chinese blockchain games and systems in which users can obtain a digital card, buy these cards to play the game and increase the power of the game, and sell them if they wish. Here NFT builds only the platform.

Of course, some cards are not used in the game and are more “collectible”; That is, people buy and maintain them only because of their special shape and characteristics. These types of cards are related to the use of NFT in digital art, which we mentioned above.

Here are some of the most important digital card provider projects in the form of NFT that can be used by everyone:
  • Sorare: It is a fantasy football game in which players can build their own team with the cards of well-known players and compete with others in leagues. Each player card (Common Cards) is an NFT and is stored in the user’s personal wallet. Scores are also determined by the actual performance of the players. For example, a player can include Karim Benzema in his team, and if this player scores a goal, the player’s score in Surrey will increase compared to others who do not have Benzema in their team. Free cards are initially given to players, but rare cards for big players must be purchased or won through a match. It is not possible to sell free cards in the game, but with free cards you can participate in some small tournaments. In these tournaments, the top players are given a rare card that is worth the money.
  • CryptoKitties: A blockchain-based game that is one of the first and most popular NFT projects. In this game, users collect and trade virtual cats. Cats, each with its own set of characteristics, can reproduce and make new cats. If you have superior breed cats or your chances are good, according to genetics you can own a rare and highly valuable cat.
  • Gods UnchainedAtrium is a blockchain-based fighting style game in which players can fight others with digital cards. Starting the game is free and players will receive free cards first. Free cards are not NFT and have no value, but there are special cards with unique features in this game that are NFT-style given to top players on a periodic basis and can also be purchased.
  • Axie Infinity: Is a blockchain based game in which players are faced with cartoon characters called Oxy. Each pet-shaped ax is an NFT and has complete control over the player, which players use to play various games.

At present, in order to succeed in most of these Chinese block games, you need to pay and it is either not possible to play for free, or if there is, the games are designed in such a way that the user has to buy a card to continue to succeed. So before participating in these projects, think about your pocket!

Earth in virtual worlds

As I write this, a piece of virtual land, where you can never set foot on it, is up for sale on the OpenStreet for $ 39,500, and it’s interesting to note that the landlord wrote in the description. : “[Earth] in a good place…”

دسنترالندDecentralland environment; Decentralized land!

Virtual Worlds or Metaverse are more than just a game. In these worlds, you have your own identity, you walk around the city with your friends, exhibitions are held, you can go to the amusement park (computer games venue) or museums (digital art exhibits). You can buy clothes, houses and land for yourself and even build on your own land.

Of course, the expansion of these worlds is still technically challenging and not very high quality, but in the future these challenges will be met and we will see a large presence of people in these worlds.

Proxy tokens, or NFTs, are a boon to the virtual worlds, as they bring the same real-world ownership benefits to the digital world. For example, if you buy a dress in a virtual world that has received help from the NFTs, the dress actually belongs to you as a token on the Chinese block that you can save on your wallet and transfer to someone else if you wish.

Get permission from someone without needing to. Here, too, NFT is built by the platform.

The following projects are the most popular virtual worlds that use NFT innovation:

  • Decentraland: Centralland is a blockchain-based virtual world that uses the Atrium network. As the name implies (Decentralized Land), the ultimate goal of this platform is for its users to manage it and for everyone to be able to have their own virtual life in this world and produce useful content and services. Currently, the main asset traded in this game is land. Each land is an NFT that is exchanged for the MANA token (Central Currency of Decentralland). Lands have a different value than the area in which they are located. Decisions about the future of the world will also be made by voting in the Dassentland community.
  • SandBoxSandbox is a decentralized virtual world where people can build games, create 3D assets, and make money by playing games and selling assets. At the time of writing, this project is still in the experimental phase and still has a lot of work to do in terms of user interface.
  • Cryptovoxels: A virtual world made of three-dimensional pieces operating on the Atrium blockchain. People can experience life in this world and have their own land and possessions.

Internet domains

The issue of domain ownership has always been a hot topic among free internet enthusiasts. They all agree on this fact: in today’s Internet (centralized Internet) people are not the real owners of domains.

Decentralized domain name providers have come up with solutions to address these issues and the challenges associated with moving Internet domains.

To solve problems such as censorship, infringement, as well as the time-consuming process of transferring domains to others, these companies record the ownership information of each domain on the blockchain, so that a simple transaction on the blockchain can also transfer ownership.

Decentralized domain is one of the most important aspects of NFT, and unlike most other types of NFT that have a more collectible use, the use of these domains to solve a problem is more noticeable.

Each domain is a token that is stored in the owner’s personal wallet and he can use it as an account number to receive money (digital currency) or a site address.

The following two companies are currently the largest providers of Internet domains in the form of NFT:

  • Ethereum Name ServiceOr ENS for short : The company offers .ETH-based Atrium domains. These domains can be used to interact with the Atrium blockchain and receive etherium-based ether and tokens, as well as on websites.
  • Unstoppable Domains: The company offers .Crypto domains that, like ENS domains, are used to receive digital currencies and use websites, except that the company has a more centralized structure.

Important Note : China Blockchain-based domains are not yet compliant with standard domain standards (Icon standards), and at least at this point they can not be used as easily as regular domains. Therefore, at the time of writing, purchasing these domains only makes sense in the long run or for use as an account number (wallet address), not for use on websites.

From the endless sea of ​​NFTs, we have only seen shallow points. In the not-too-distant future, there are likely to be many more types and applications of NFTs that cannot be accurately imagined at this time.

Wherever there is a need to prove ownership of various items in the digital world, we can feel the emptiness of NFTs.

Even at the present time, non-proverbial tokens are more widely classified, but this article only mentions the types that have the largest number of users at the time of writing.

NFT Trading

To trade any NFT‌, we must refer to the NFT بازار market, which is available to everyone in the form of a site and application.

Usually, any platform that allows NFT creation has its own marketplace for trading. For example, on the Foundation platform, after creating NFT, you can put it up for sale on the same platform.

In addition to the ability to trade in markets within each platform, there is also the possibility of trading NFTs in public markets. In public markets, such as digital currency exchanges, all types of NFTs are traded from different platforms.









At the time of writing, the top public marketplace for NFTs is the Open Platform. OpenSy supports NFT range, and more than 14 million various non-unique tokens have been registered on the website for trading.

In terms of classification and diversity, NFT Open is a notch above other platforms, but most professionals prefer to sell their work on the same NFT platform, and Open is more useful for retail traders.

In addition to network fees, putting a new NFT up for sale on the open is free, but after the sale, the website charges 2.5% of the commission. There is no significant public market to introduce at this time, except for the opening.

Risks and costs

As I mentioned above, your direct NFT activity (at least at this point) can be very risky and costly. Here are some of the major risks and costs of working with NFTs:

  • Fees : Most NFT projects are currently operating on the Atrium network, and this network is facing a serious fee challenge. At the time of writing, each transaction on NFT-related smart contracts costs an average of more than $ 50.
  • Get paid to win : You currently have to spend a lot of NFT projects (especially games) to increase your chances of selling or winning, and there is no return guarantee. In some NFT games, if you do not pay, you probably will not have a chance to win (earn money).
  • Invalid platforms : NFT space is less than four years old, and as of this writing (early 2021), NFT host websites and applications are still in close competition with each other. So there is not much knowledge of these platforms yet, and it is still difficult to check smart contract codes (to ensure they are not stolen or censored). Thus, an NFT platform may be set up for fraudulent purposes or its smart contract codes may be technically problematic.
  • When you buy and you can not sell : There is no guarantee that the value of an NFT will not close to zero after a while. There is also no guarantee that after purchasing an NFT, a person will be willing to buy it at a higher price than you.

Certainly more can be added that can only be understood by experience in this field. In general, you should know that the NFT field is now like the digital currency market in 2016; Many expensive projects, NFTs, and platforms today will probably be gone in a few years.

Given all these arguments, if you are not an artist, techie (geek) or collector, and your goal is simply to make a profit from the markets, investing in NFT tokens makes more sense. For example, Decentralland playgrounds are each a unique token, but if you want to buy these tokens (fields), you must use the Decentralland functional token, ieMANAuse. It may make more sense to invest in mana here.


Building an NFT on its own with multiple platforms is not difficult on its own, but if you are not a celebrity or your NFT does not have special features, you should not expect anyone to be willing to buy it from you.

There are many different types of proxy tokens, the most important of which you will read about in this article, so an image or video token is just one of many types of NFT.

In this article, I have tried to introduce the best platforms for each type of NFT, but be sure to research each platform yourself before doing anything to avoid technical problems or scams.

Now you have to be famous and an artist or you have to have a lot of money to be effective in NFT. So if you are planning to work in this field, be sure to consider the fact that the risk of not returning the capital due to commissions and buying a worthless NFT is very high.
