What Is Minting an NFT? The Ultimate Guide

When you mint an NFT, you are essentially creating a new NFT and recording its creation on the blockchain. This confirms your ownership of the asset and generates a permanent digital record. 

Minting is what transforms a regular digital file into a verified NFT that can be bought, sold, traded, or licensed.

Let’s take a deeper look at what minting an NFT entails.

What Is Minting an NFT?

Minting an NFT refers to the process of creating a new NFT and recording its existence on a blockchain. It involves creating a new block on the blockchain to represent the new NFT.

This block contains the NFT’s metadata, such as its:

  • name
  • description
  • image or video file
  • creator
  • timestamp of creation
  • blockchain identifier
  • ownership and other attributes.

When minting an NFT, a unique cryptographic hash is generated using that specific metadata. This hash serves as the NFT’s unique digital fingerprint and allows it to be tracked and verified across the blockchain. No other NFT will have the exact same hash.

So, in summary, minting an NFT performs two key functions:

  1. It creates a new, unique NFT with specific attributes and metadata.
  2. It records the new NFT’s creation on the blockchain via a new block, securing its legitimacy and tracing its ownership history.

The end result is a certified digital asset with proof of ownership that can be easily bought, sold, and traded.

What Is an NFT, Anyway?

Non-fungible tokens (NFTs) have exploded in popularity over the last couple of years. From art and music to sports memorabilia and virtual real estate, all kinds of unique digital assets are being turned into NFTs. Before we go into how minting an NFT works, what exactly are NFTs?

An NFT is a cryptographic token that represents ownership of a unique digital asset. Unlike cryptocurrencies like Bitcoin or Ethereum, NFTs are not interchangeable. Each NFT contains distinguishing information that makes it entirely one-of-a-kind. This allows digital creations like art, music, videos, collectibles, and more to be tokenized and sold just like physical assets.

How Do You Mint an NFT?

Minting an NFT is a relatively straightforward process that can be broken down into a few basic steps:

1. Create a Digital File

The first step is to create the digital file that will become your NFT. This can be any file format, like JPG, PNG, GIF, MP3, MP4, 3D model file, or even a text document.

2. Set Up a Crypto Wallet 

To mint an NFT, you’ll need a cryptocurrency wallet that is compatible with NFTs. This is where you’ll store your NFT once it’s minted.

Popular options include MetaMask, Coinbase Wallet, Trust Wallet, and others. These wallets let you securely store crypto assets and NFTs.

3. Connect Wallet to NFT Marketplace

Next, you’ll need to connect your wallet to the NFT marketplace where you want to mint your NFT. Popular marketplaces include OpenSea, Rarible, SuperRare, and Foundation. Connecting your wallet allows you to use it for transactions on that marketplace.

4. Upload File and Fill in Details

Once your wallet is connected, you can upload your file to the marketplace and fill in the NFT’s metadata. This includes setting a:

5. Pay Gas Fees and Mint

You’ll need some Ethereum or SOL crypto coins in your wallet to pay “gas” fees to mint the NFT. Gas fees fund the computational work required. Once paid, you click mint, and your NFT will get created and added to the blockchain.

That covers the basics of how to mint an NFT. Next, let’s look at what happens once you click that mint button.

What Happens When You Mint an NFT?

When you finally mint your NFT, a few key things happen under the hood:

  1. The NFT metadata and file are uploaded to an NFT storage service like IPFS. This creates a permanent decentralized record.
  2. A new block is created on the blockchain to represent the new NFT. This records its unique attributes and the timestamp of its creation. 
  3. Your wallet address is recorded on the blockchain as the owner of the new NFT. This proves your ownership.
  4. A unique cryptographic hash is generated based on the NFT’s data. This becomes its digital signature.
  5. A token ID is assigned to the NFT for tracking it on the blockchain. This functions like its unique serial number.
  6. You pay the gas fee for the computational work of adding the NFT to the blockchain.
  7. The NFT transaction is executed, and the new NFT is added to the blockchain ledger.
  8. The NFT is now visible in your connected wallet and on the NFT marketplace.
  9. You now own the NFT and are free to sell, trade, license, hold, or transfer it as you wish.

So, in summary, minting finalizes the creation of your unique digital asset, pays for the work of recording it on the blockchain, and allows you to establish verified ownership of that asset.

How to Tell if an NFT is Minted

If you come across an NFT in the wild, how can you tell if it has already been minted? Here are a few ways to check:

  • View Metadata – Established NFTs have viewable metadata that displays key details like the title, description, creator, blockchain type, token ID, etc.
  • Mint Date – Look for a clear mint or creation date in the metadata or on the NFT’s page. This shows when it was minted.
  • Blockchain Explorer – Copy the NFT’s contract address and look it up in a blockchain explorer. It will display the mint transaction if minted. 
  • Transaction History – If transactions, bids, or sales are visible, it means the NFT was minted and purchased.
  • Token ID – Valid NFTs have an assigned token ID number visible on the blockchain and marketplace.
  • Verify Contract – Check that the NFT’s contract address is a valid NFT contract, signaling a minted asset.

If you can view the metadata, see a past mint date, locate the minting transaction, and verify other attributes as outlined above, you can be confident that an NFT has already been minted and added to the blockchain.

What Happens After an NFT is Minted?

Once an NFT is successfully minted, a few things can happen:

Listing for Sale

The most common next step is listing the new NFT for sale on a marketplace. This allows others to view and potentially purchase your NFT. The sale can be via auction, at a set price, or using declining pricing over time. NFTs can sell for anywhere from a few dollars to tens of thousands or even millions of dollars in rare cases.

Trading or Transferring Ownership  

You also have the option to trade your NFT with another user or transfer ownership directly via wallet addresses without listing it for sale publicly. NFTs can be exchanged for other NFTs, cryptocurrencies, real-world currencies, and more.

Earning Royalties

Some NFTs are programmed so that the original creator gets a royalty every time it gets sold to a new owner. This is an attractive passive income stream. Royalties are usually 5-10% of each sale price.

Holding for Investment

You may opt to hold onto your NFT if you think it will increase in value over time, like an investor holding any asset. NFTs gain value from increased demand and their limited supply.

Licensing for Use

NFT creators can also license their NFTs for certain commercial uses. For example, allowing prints of digital art NFTs to be sold while you retain the NFT. Or licensing the use of a music NFT track in a commercial.

So in summary, minting an NFT opens up a variety of opportunities to monetize and gain value from your creation. Overall, it gives creators more control and ownership options.

While NFTs present exciting new opportunities, there are also some emerging legal and regulatory considerations to keep in mind.

When minting any NFT, make sure you have full legal rights to the underlying content. You cannot mint an NFT of someone else’s copyrighted work, like characters, products, or music, without permission. Doing so leaves you at risk of copyright claims.

Terms of Service

Carefully review the Terms of Service for any NFT marketplaces you use. They outline acceptable use cases and content standards that must be followed.

Licensing Deals 

If your NFT will feature someone else’s work, like celebrity images, you may need licensing deals or permissions in place before legally minting.

Evolving Regulations

Because NFTs are so new, regulations continue to evolve. Agencies like the SEC are still evaluating how to monitor and regulate various NFT types and markets. Know that policies could change.


Profits from creating and selling NFTs are subject to capital gains taxes and income taxes. Track your activity closely to properly report taxes.

While the regulatory landscape is uncertain, following copyright laws and terms of service and securing licenses where needed can help reduce your risk. However, consult qualified professionals for legal and tax advice on your specific NFT activities.


Minting your own NFT lets you take full advantage of the possibilities enabled by blockchain technology and digital ownership. By converting your original creations into verifiable NFTs, you can profit from your work in innovative ways.

But before you mint, make sure you fully understand the process, costs, and technical requirements. Your content also needs to be of high quality and legal to use for minting purposes. Once you jump in, you can leverage NFT marketplaces to sell or license your new NFT creation and even earn royalties in the future.


No, minting an NFT means creating and generating a new NFT to represent a digital asset you own. Buying an NFT means purchasing an NFT that someone else has already minted from them on a marketplace.

Minting is necessary if you want to claim verified ownership of a unique digital asset in the form of an NFT. If you don’t need to prove ownership or sell an NFT, you don’t need to mint.

Minting is the process of creating a new NFT and recording it on a blockchain. Selling is listing your NFT for purchase on a marketplace after minting it to transfer ownership for payment.

The minting cost is based on blockchain network gas fees at the time and can range from $5-$500+ currently, depending on the blockchain and congestion.

After minting, you own the NFT and can sell it, license it, hold it for investment, earn royalties from sales, or transfer it like any other asset based on the blockchain.

On OpenSea, minting means using their NFT creator tools to create and generate a new NFT on the Ethereum or Polygon blockchains, which is then listed in your OpenSea collection.

Benefits include monetizing your digital creations, retaining indefinite ownership rights, having a public, transparent record, selling globally with no middlemen, earning royalties, and leveraging scarcity.

The easiest way is to use an NFT marketplace like OpenSea that handles the blockchain interactions for you. You simply connect a wallet, upload your file, add metadata, and mint directly on OpenSea.

Yes, you can earn money from minting and selling NFTs if you create something in demand that buyers are willing to pay for. But there are no guarantees of profit like any other market.

Yes, OpenSea charges a gas fee in ETH to mint NFTs, which covers the cost of executing the Ethereum transaction. Current OpenSea minting fees range from around $5-$100 on average.

The cost to mint on OpenSea varies based on Ethereum network congestion and gas fees at the time of minting. Fees may range from $5 on the low end up to $100+ on the high end.
