NFTs or Non-Fungible Tokens are unique tokens that represent digital files or physical objects. They are most commonly used especially in digital art and collectible items. NFTs have completely changed the way people use blockchain technology.

Through this new technology, it is possible to sell digital artworks in the form of digital tokens where digital collectors can bid on auctions and pay with cryptocurrencies, thus opening up a new digital world for content creators and digital artists to monetize their digital content.

Research and uses of crypto-collectibles became very popular after the digital artist Beeple, sold his digital image collage “Everydays: The First 5000 Days” for $69.3 million at an auction at the traditional auction house, Christie’s.  With this sale, he made Beeple the third living artist after Jeff Koons and David Hockney.

The interest in minting NFT has been growing day by day. The search for the cheapest or most economical way to mint NFTs comes from the fact of getting considerable returns from creating an NFT art or crypto art on the Ethereum blockchain, when it comes to gas fees.

What is a Non-Fungible Token (NFT)?

NFT stands for non-fungible token. An NFT transforms a digital file into a digital asset. An NFT token is created and stored on a blockchain (usually Ethereum), serving as proof of ownership and provenance of a specific item. It works like a digital certificate of authenticity that can be easily verified by anyone anywhere in the world on a blockchain.

When it comes to the NFT space or NFT world, crypto collectibles or digital collectibles can represent various items including photographs, images, audio or music files, plain text files (documents, PDFs, or tweets), 3D models, online game items, virtual properties, virtual worlds, metaverses, web domain names, and other valuable assets.

A non-fungible token ensures that a digital work of art or any digital item or file is a unique token, collectible and tradable. Many consider them a revolution for the digital art market.

How do NFTs or non-fungible tokens work?

Non-fungible tokens or NFTs are executed by smart contract blockchains and specialized protocols. The most widely used smart contract blockchain for NFTs is Ethereum.

Ethereum has become the most widely used blockchain when it comes to minting NFTs. This is because the Ethereum blockchain supports a wide range of NFT token standard, including ERC-721, ERC-1155, ERC-809, ERC-994, ERC- 1201, and ERC-998. The ERC-1155 standard for example allows the creation of fungible tokens and non-fungible tokens (NFTs).

Other platforms, blockchains and smart contract protocols that also support the creation of NFTs are: Flow, WAX, Tezos and Binance Smart Chain.

When an NFT token is created it stores metadata about a digital file or a valuable item, the most common form is digital art.

The components or details of this NFT token metadata can include the artist or creator of the item, the description of the item, the price, the NFT creation date, the ownership of the item, specifications such as royalties, the transaction history of the asset, the new owner, and the location links of the file representing the NFT usually on the decentralized IPFS (Interplanetary File System) server.

Non-fungible tokens or NFTs are used for various purposes, usually it serves as verifiable proof of unique digital items, but the main purpose is to create verifiable digital scarcity of digital items. But their main use is in digital art. They help to prove authenticity and ownership of digital artworks.

What does it mean to mint NFT?

In simple terms, Minting NFT refers to the process of turning a digital file into a crypto collectible or digital asset on the Ethereum blockchain. The digital item or file is stored in this decentralized database or distributed ledger forever, and it is impossible to edit, modify, or delete it. As is the process of creating fiat coins, when a manufacturer mints a physical coin, the process of uploading a specific item onto the blockchain is known as “minting”.

Or we can define “NFT Minting” as the process by which your digital art or digital content becomes a part of the Ethereum blockchain. The NFT minting process is Similar to the way metal coins are minted and put into circulation, non-fungible tokens are also “minted” after they are created. This process turns a simple file into a crypto asset easily traded or bought with cryptocurrencies on a digital marketplace without an intermediary.

During the minting process, the creator of the NFT can schedule royalties from every subsequent sale, which will be a commission he can receive whenever his work is sold to another person, or is traded on the secondary market.

How long does it take to mint an NFT?

It is difficult to estimate how long it might take during the process of minting NFTs. But most NFT platforms, tools, and NFT marketplaces make the NFT creation process easy.

By default, the process of creating an account or logging into the major NFT marketplaces is just to install a browser chrome extension called Metamask, which is an Ethereum wallet.

Now, turning your digital content into NFT or uploading the file to the NFT marketplaces and listing it for sales, is similar to the process of uploading a video on YouTube, uploading a music file on Spotify and is even similar to the process of listing a digital item or product for sale on Amazon, Ebay or Etsy.

All you need is to upload the file (PNG, JPG, GIF, MP3 or MP4), assign a title and subtitle, add a description, set up royalties and list it for sale.

Does minting an NFT cost money?

Yes. Most NFTs and NFT markets are stored and hosted using the smart contracts of the Ethereum blockchain.

Using the Ethereum blockchain (creating NFTs, buying, selling, or transferring an asset at an Ethereum address) has a cost, and that cost is called the “gas fee” or “Gwei”.

This fee typically costs between $50 and $200, depending on the demand of the Ethereum network or the NFT platform.

Can you mint an NFT for free?

You cannot mint an NFT for free.  Currently, the largest NFT marketplaces are hosted on the Ethereum blockchain and the Binance Smart Chain protocol.

What you can do when minting or creating an NFT is to choose a more affordable platform.

The most popular and most economical NFT marketplaces on the Ethereum blockchain are: the OpenSea NFT, Rarible, and Mintable.

The most popular marketplaces on the Binance Smart Chain network are BakerySwap, Juggerworld and Treasureland.

After selecting the platform and before you start minting NFTs, you will need a digital wallet or Ethereum wallet.

The most popular digital wallets are Metamask, Trust Wallet, Coinbase Wallet, and Rainbow.

When you create a wallet it generates a “seed phrase,” which is a string of 12 random words that allows you to access your funds in case you lose access or forget your wallet password.

A cryptocurrency wallet or digital wallet is composed of a ‘public wallet address’ and a ‘private key’. The ‘public wallet address’ is usually used to transfer any cryptocurrency or NFTs from one wallet to another, while the private keys or secret keys allow you to have control over your funds.

Another cryptocurrency wallet that is becoming popular and worth mentioning is Fortmatic/Magic, which allows the user to log in with an email address and password. The Fortmatic (Magic) wallet will create and store the “seed phrase” or “secret key” for you, securely and simply.

How much does it cost to mint an NFT on OpenSea?

OpenSea NFT is currently the first and largest NFT marketplace, and is currently the most economical way to mint NFT tokens, because it does not require users to pay transaction fees or gas fees every time they create other NFTs.

OpenSea NFT users only pay minting fees or gas fees once, at the time they create NFTs and customize their NFT collections. In the case of selling NFT, buyers offset gas fees.

When you mint your NFT on OpenSea, the token is automatically transferred to your crypto wallet (the default wallet is Metamask) and you can sell your NFT on multiple platforms i.e. you can create an NFT on OpenSea NFT and sell it on any platform or NFT market powered by the Ethereum blockchain.

How do I mint an NFT?

Literally any digital content or file can be turned into an NFT art or NFT asset.

So if you are a content creator, graphic designer or digital artist you can easily turn your work, be it 3D models, text files (documents, PDFs or tweets), videos or music into a collectible crypto asset with real cash value.

The process is generally simple, if you are using Google Chrome browser, you can easily install the browser extension “Metamask” – which is the default wallet of most NFT marketplaces and blockchain apps. But, make sure your wallet has Ether (ETH) , the native cryptocurrency of the Ethereum blockchain. After that, you are ready to create your first NFT.

Here is the default of most major marketplaces and NFT platforms:

Connect your wallet to the NFT marketplace.

Your profile on any Ethereum-based NFT marketplace (OpenSea NFT, Rarible, Nifty Gateway, Foundation or SuperRare) will be activated as soon as you connect your Metamask wallet, and from there you can create a username or display name, add a profile photo or cover photo of your collection, and add links to your social networks, personal blog, e-shop, or portfolio page.

Upload your file

The process of uploading your file or creating your own NFTs is quite simple, just look for the “Create an NFT” page in your chosen marketplace, from there you can upload images in PNG, JPG or GIF formats, a music file in MP3 or .Wav formats, a video file in MP4 format or a 3D file in GLB format.

Remember that an NFT is not the digital file or any digital content itself, but rather a representation of the file or content.

Given that the Ethereum blockchain will be able to store your NFT tokens for quite some time, you need to make sure that the file being represented by an NFT is being well stored. It makes more sense to store the digital file in a decentralized database, such as in IPFS (InterPlanetary File System).

Using centralized databases, such as cloud hosting services, can be very risky for the security of your file. Using temporary cloud storage services like Google Drive or any other centralized database may not be a better long-term file storage solution appropriate for digital items turned into NFTs.

Mint your NFT

After uploading your file or your digital artwork, here you can add or assign a title and a description of the item, and then click the “Mint NFT” or “Is for sale” button, depending on the platform.

Approve Gas Fee or Transaction Fee

All transactions made on the Ethereum network have a cost, and this cost is paid with the Ether (ETH) cryptocurrency. Hence, at this stage, a gas fee or transaction fee will need to be approved in your digital wallet to complete the minting of the NFT.

Just to clarify one thing, gas fees are not fees created or charged by the NFT platform or marketplace you are using, they are paid for using the Ethereum blockchain.

Wait until your NFT is minted

After uploading the file and paying the gas fee, the NFT minting process is automatically started. During this process the Ethereum smart contract executes a code that will be implemented in your artwork on the Ethereum blockchain.

Once you list your NFT for sale and someone is interested in buying your artwork, they can bid on your work. If you accept the bid, the records will be publicly recorded, the NFT token will be transferred to the new owner, and the owner’s identity and the history or details of the trade will be recorded on the Ethereum blockchain.
