What is NFT Minting and how does it work?


NFTs, or non-fungible tokens, are blockchain-based tokens that prove ownership and provenance of digital items such as images, video files and even physical assets.

They’ve shot to prominence in the last year, with multi-million dollar sales of NFT artwork grabbing headlines, while Twitter has been overrun by NFT avatars like Bored Ape Yacht Club, CryptoPunks and Pudgy Penguins. Even big brands and celebrities have jumped on the NFT bandwagon—but how do you go about creating a non-fungible token?

What is Nonfungible token?

A non-fungible token (NFT) is a type of cryptographic token on a blockchain that represents a unique asset. These can either be entirely digital assets or tokenized versions of real-world assets. As NFTs aren’t interchangeable with each other, they may function as proof of authenticity and ownership within the digital realm.

What is NFT Minting?

Minting is the process of tokenizing a digital file with cryptography. Tokenization is the process of turning an asset into a digital token that can be moved, stored and recorded on the blockchain.

Minting an NFT—the fancy term for “creating on the blockchain”—is a seamless experience, if you follow these beginner-friendly steps.

How to get started minting Ethereum NFT?

Now, let's start minting on OpenSea, the most popular NFT marketplace.

How to connect crypto wallets?

To start minting an Ethereum NFT, you should make sure you have already kept some ETH in your crypto wallet, like MetaMask. If you don't know how to send ETH to your MetaMask, get started here.

In the following guide, we’ll be using the MetaMask, but the steps are nearly identical for other wallets too.

First, find your MetaMask wallet on your browser and make sure you have already logged in.


Then, open and visit Opensea with the same browser Metamask installed. Find "Account" on the top right corner of the homepage and click "Profile".


Next, you will be prompted to connect your crypto wallet. Select MetaMask and continue.


After selecting Metamask, you will get a pop-up window about the notification of connecting with Opensea. Complete two steps to confirm your account connected to Opensea.



OpenSea will ask you to agree with signing with your MetaMask. Click “Sign” and your Opensea wallet’s successfully connected with MetaMask!


Now your unnamed profile is created. Click "Setting" on the right of the page.


In this step, you need to enter a username and an email address to verify your account. You can also modify the colors of profile image and banner to make it prettier. Link to your other social media is optional, you can skip it and save the settings.


If you’ve taken care of the verification email, then your profile should be all set! Now it’s time to create your NFT.

How to create NFT?

To mint an NFT on OpenSea, click “Create” next to your profile picture on the top right corner.


To create a new NFT, you need to upload the supported file type to the given place. Name your NFT and it is better to add a description about your NFT.


If you already have your own collection, you can select it. You can leave the rest of the options as default. After uploading a file and naming your NFT, scroll down and click “Create.” Your own NFT get real now!


How to Sell NFT?

We will use an image as an example.

After creating your own NFT, you can see how your NFT will appear on OpenSea.

It is not on sale, you can list your NFT for sale. Click “Sell” on the top right, and the following page will appear.


You can sell it for a fixed price or put it up for auction.

If listing for a fixed price, you won’t pay for the gas fee (any transaction on Ethereum incurs these transaction fees). Instead, the buyer will bear the burden of gas. For auctions, sellers pay the gas.


Similar steps with listing with a fixed price, for timed auction, you can choose selling to the highest bidder or with a declining price. Please learn about it before you complete the listing.


OpenSea will charge 2.5% in commission fees when your NFT sells. When you’re ready, click “Complete listing.” For the first time to sell on OpenSea, you need to initialize your wallet.


You will get an instant pop-up notification for initializing MetaMask. Check the details and confirm the initialization.


You are also asked to approve this sale and also confirm your price. What you have to do is to sign off all through Metamask. If completed all above the steps, congratulations on minting your first NFT!

This guide is based on minting on Opensea, which doesn't mean it's the only choice. You can also mint NFT in other NFT marketplaces or blockchains. Just explore and enjoy yourself in minting NFT!
