Fortunately, minting an NFT is a straightforward process that can be done with just a few clicks.

This guide will take you through the step-by-step minting process in order to make you able to create your NFT collection. So, buckle up and get ready to enter the exciting world of NFTs!

What is an NFT?

What is an NFT? 

Before learning how to create (because mint NFT = create NFT) an NFT, it’s essential to understand what an NFT is.

So, an NFT stands for “non-fungible token.” The term “non-fungible” means something unique and cannot be replaced with something else. Unlike physical money or cryptocurrencies, which can be exchanged for each other, NFTs cannot be traded for anything else. 

Each NFT has a special digital signature that makes it one-of-a-kind.  

This uniqueness is what makes NFTs so valuable for creators. In the past, digital artwork could be easily copied, and it was hard to tell which file was the original. But now, with NFTs, creators can prove ownership of their original work.

NFTs can be digital versions of different things such as photos, videos, audio files, or any other digital format. Examples of NFTs include artwork, comic books, sports collectibles, trading cards, games, and much more.

To “mint” an NFT means to create a unique digital asset that is stored on a blockchain. So, logically, an NFT is a blockchain-based asset. This asset can be anything digital, like a piece of art, a video, or even a tweet. 

Think of minting an NFT like creating a unique trading card. Like how each physical trading card has its own distinct image, rarity, and value, each NFT is unique and has distinct features. When you mint NFTs, you create a unique digital trading card that can’t be replicated or duplicated. 

To create an NFT, you’ll need to use a platform that supports NFTs (NFT Marketplaces), like OpenSea, Rarible, or Nifty Gateway. You’ll upload your digital artwork, and the platform will create a unique code, or digital signature, that proves ownership of the original asset. This code is what makes the NFT valuable because it proves that you are the owner of the original digital asset. 

For example, let’s say you’re an artist who has created a unique piece of digital art. You can mint that artwork as an NFT, making it a unique, one-of-a-kind digital asset. Once your NFT is minted, it can be bought, sold, or traded just like a physical trading card, but it will always be one-of-a-kind and can’t be duplicated.

First, we will present a step-by-step guide on NFT minting in a general way, and later, in a specific subtopic, we will explain more clearly how to create NFTs using the OpenSea platform. So, here is a general step-by-step guide on minting NFTs: 

  1. Choose a Platform (NFT Marketplaces) – The first step is to choose a platform that supports NFTs. Some popular NFT Marketplaces or platforms include OpenSea, Nifty Gateway, and Rarible. 
  2. Connect Your Wallet – Once you’ve chosen a platform, you must connect your cryptocurrency wallet. This will allow you to buy, sell, or trade your NFTs on the platform. 
  3. Create Your Digital Asset – The next step is to create a digital asset you want to mint as an NFT. This can be anything from a piece of art to a tweet. 
  4. Upload Your Digital Asset – After generating your digital asset, you’ll need to upload it to the platform. The platform will generate a unique code, or digital signature, that proves ownership of the original asset. 
  5. Set Your Parameters – When minting your NFT, you’ll need to set parameters for things like the name, description, and price of your NFT. These parameters will be visible to anyone who views your NFT on the platform. 
  6. Mint Your NFT – Once you’ve set your parameters, you can mint your NFT. This will create a unique, one-of-a-kind digital asset that is stored on a blockchain. Your NFT can now be bought, sold, or traded on the platform. 
  7. Promote Your NFT – To increase the visibility of your NFT, you’ll need to promote it on social media or other platforms. This will help attract potential buyers and increase the value of your NFT. 

Remember that while minting an NFT is relatively straightforward, it’s essential to research and understand the potential risks and rewards of the NFT market. 

Mint an NFT on OpenSea using MetaMask

1. Connect Your Wallet and Set Up Your Account

Connect Your Wallet and Set Up Your Account 

The first step is to connect a crypto wallet to an NFT marketplace. On the OpenSea NFT marketplace, you can start by clicking on the wallet icon or the “Create” button in the page’s top right corner. Other NFT marketplaces will have similar prompts to connect your wallet and create a profile.

Depending on your wallet type and device, you may be asked to scan a QR code or download your wallet to your computer. In our case, the whole process will be done using MetaMask Wallet. 

After your wallet is connected and your marketplace profile is created, the next step is to complete your profile. This involves introducing yourself to the NFT community, providing links to your website or social media pages, and specifying which cryptocurrencies you will accept as payment for your NFTs. This will help potential buyers learn more about you and your work and make transactions smoother. 

2. Click “Create” to Create Your Item and Fill in the Suitable Information

To start creating your NFT, go to the marketplace’s homepage and click the “Create” button located in the top right corner. This will prompt you to upload a digital file and give your NFT a name.

You can also add a description and an external link to your website or social media and choose the blockchain technology you want to use as the foundation for your NFT. This is where you can set up how much you’ll be paid in royalties if your NFT is sold again later on.

A standard royalty payout is between 5% to 10% of the secondary sales price. 

After completing the necessary information, click “Complete” to finish the process. Congratulations, you have now successfully minted your first NFT! 

3. Fund Your Wallet (If It Doesn’t Already Have Some Funds) *

So you can sell the NFT you just minted about, the network needs to do some computing, and you will be charged a fee for this, known as a “gas fee.” So, a funded wallet is required. Monitoring these fees is essential, as some can be higher than expected. 

To sell your first NFT, you must purchase some Ethereum or another cryptocurrency you plan to use on a crypto trading app and deposit it into your wallet. Then, depending on your marketplace, you can transfer the cryptocurrency from your wallet to your NFT marketplace account.

Some marketplaces, like OpenSea, allow you to purchase crypto directly from your marketplace profile using a payment method like a credit card. 

4. List Your NFT

To sell your NFT, click the “Sell” button in the upper right corner of your NFT’s description page. This is where you’ll specify the details of your sale, such as whether you want to set a fixed price based on your cryptocurrency of choice or run a timed auction.

Some marketplaces may allow you to set up royalty payouts for ongoing passive monetization of your work. Keep in mind that the marketplace will disclose any related fees for selling. 

Once you’ve decided on the details of your sale, click “Complete listing.” The marketplace will calculate the gas fee based on the current activity level on the cryptocurrency network, and you’ll need to pay this fee from your crypto wallet.

On some marketplaces, like OpenSea, there is a service fee of 2.5% of the NFT selling price for handling the listing. 

The gas fee amount will vary and can change from minute to minute, but once you’ve paid it and approved the final terms, your NFT will be listed and available for purchase on the marketplace.

To increase your chances of selling NFTs, you could also create some hype around your collection through an NFT giveaway for the crypto community.

If you’re thinking about creating an NFT, there are several benefits to consider: 

  • NFTs are a great way to showcase your work and build a following; 
  • They eliminate the need for physical shipping and storage; 
  • NFTs are relatively easy to create with a digital file of your artwork and a blockchain platform; 
  • They offer increased liquidity, making it easier to monetize digital arts and assets; 
  • Once created, NFTs can be traded or sold like any other piece of art. 


How Long Does It Take to Mint NFTs?

The time it takes to do NFT minting can vary from a few minutes to several hours, depending on the platform and file size. To mint your first NFT, you must upload your artwork, set up metadata, and wait for the platform to process and mint the token.

Some platforms offer priority for minting fees to speed up the minting process. File size and artwork complexity can also impact minting time.

How Much Does It Cost to Create an NFT?

The cost of creating an NFT can vary, usually ranging from a few to hundreds of dollars, depending on the processes and platforms used. If you create the artwork yourself, there may be no cost. If you collaborate with an artist, the cost may vary depending on their fees.

Minting the NFT involves transforming the artwork into a non-fungible token on a blockchain, which incurs a gas fee that can range from less than $1 to thousands of dollars, depending on the blockchain.

Finally, listing the NFT on a marketplace may require a listing fee, and you may need to approve WETH for use. 

How to Mint an NFT for Free?

In order to mint your first NFT for free, you must first not turn to an artist for your NFT but do it yourself (which requires a bit of talent), and then you can turn to a platform that offers you the possibility to mint your project for free, for example, OpenSea.

However, keep in mind that on OpenSea, listing requires a small amount of money, but the minting is free. 

How to Mint an NFT on MetaMask?

You cannot mint an NFT directly in the MetaMask Wallet, but you can use it for minting on specific platforms (paying gas fees, withdrawing from the platforms, etc.) like OpenSea.

The steps for NFT minting on OpenSea using MetaMask are as follows:  

  • Connect Your Wallet and Set Up Your Account; 
  • Click “Create” to Create Your Item and Fill in the Suitable Information; 
  • Fund Your Wallet (If It Doesn’t Already Have Some Funds);

What Does It Mean to Mint an NFT?

To mint an NFT (Non-Fungible Token) means to create a unique and indivisible digital asset on a blockchain. Minting is creating and issuing a new NFT, similar to how a physical object is manufactured and given a unique identifier.

When an NFT is minted, it is assigned a distinct set of properties, such as ownership, metadata, and a specific identifier that distinguishes it from any other NFT.


Minting NFTs is a simple process involving creating a unique digital asset stored on a blockchain. To mint digital assets like NFTs, one needs to choose a platform that supports NFTs, connect their wallet, create and upload their digital asset, set parameters, and mint their NFT.  

While minting an NFT is relatively straightforward, it is important to understand the potential risks and rewards of the NFT market.  

With this guide, anyone can become an NFT creator and enter the exciting world of blockchain and NFTs. So, don’t wait any longer; create your digital art and form an impressive NFT collection or NFT collections.
