How to Mint an NFT on OpenSea -Step-by-Step Guide

OpenSea is by a thousand miles the most popular marketplace for buying and selling or to even to mint NFTs. As the NFTs market continues to soar (now worth $23 billion) more persons are seeking the best platforms to mint theirs. And if you are considering to mint your first NFT on openSea but don’t know how it works, this article is your guide. So today we are going to look at how to mint an NFT using this popular platform called OpenSea.

What is NFT Minting?

In crypto terminology, minting is the process of creating new coins by authenticating data, creating new blocks and recording the information unto the blockchain. One can also describe it as the process of tokenizing a digital file using cryptography. Through tokenization, digital files/collectible are converted into a token that can be stored in an online wallet.

To be sincere, not much was known about NFTs till of late. In fact, the market is worth $23 billion today but it was $350 million just 12 months ago. So you have over 6500% growth in a year. That is a testimony of how popular it has become in a short while.

One special feature of minting an NFT is that the cryptography that tokenizes the digital art registers the name of the owner in a blockchain in an indelible format.  By so doing it endorses the exclusivity of such art to the original owner in the entire network.

Anyone can easily mint an NFT. In fact, there are many young Nigerians who have hit millions through NFTs. But in this post we are going to restrict our discussion to how one can mint NFT on OpenSea and not other platforms.

How to Make Money Selling Your NFTs on OpenSea

OpenSea is an NFT online marketplace where sellers and buyers come together for the purpose of exchanging digital arts. At every time ‘t’ there are millions of NFTs up for sale on OpenSea. But you can only imagine that why there are such huge supply is because buyers are regularly making demands.

However, there are several NFT sellers that have been hanging in there for years and buyers are not coming. For that reason we are not going to talk much about how to buy and sell. It will be more worthwhile to teach you how to mint your own NFT on OpenSea. The truth is that minting NFT on OpenSea is not as difficult as it sounds when you have not been there.

Step1: Buying of Ethereum Coin

Bitcoin remains the most popular cryptocurrency in existence and it has been so for a while. It also command the highest value. The second most popular is Ethereum. But when it comes to buying and selling NFTs Ethereum is by a thousand mile the number one. Not even Bitcoin nor Solana comes close.

So if you ever want to deal in NFTs you need to have Ethereum. And in order to acquire Ethereum you need to create a crypto exchange account. If you don’t already have one then you need to head than to step 2 below.

Step 2: Create and link your Crypto Wallet to your OpenSea Account

After you buy some ETH, the next step is to create and connect a crypto wallet. Just like a physical wallet or your bank account, this is where you keep (store) the money you intend to use for crypto transaction. If you see any crypto you want to buy, you simply open your wallet and transfer from there. It is the same thing when you sell, the buyer will transfer to your wallet.

There are different crypto wallets out there. Some of the most popular ones are WalletConnect, Trust wallet, Metamask, Coinbase, AlphaWallet, Phantom, Glow etc. But to mint on OpenSea I will recommend you go with MetaMask.  It is among the most straightforward wallets to use. And what more, it seems to work perfectly with OpenSea.

How to Create a Crypto Wallet

As mentioned above you need a MetaMask wallet. And it is available as a browser extension, and works best with Google Chrome, Firefox and Brave. Once you install it, you can use it to store Ethereum and Ethereum-based tokens like NFTs.

So to create a Crypto Wallet using MetaMask is pretty simple and just takes 4 simple clicks:

1. Just click on MetaMask  and you see the image below

4. Click on “Get Started” to create an account with a username and password

How to Connect Your Wallet to OpenSea

You can connect your wallet to OpenSea with another 3 simple clicks:

1. Visit OpenSea home page.You will see an interface that looks like the image below

Now that your wallet is connected to OpenSea it is now time to mint your first NFT on OpenSea. But first you need to create a collection.

Step 3: Creating an NFT Collection

Now that your account is ready to process transactions on the Ethereum blockchain, it’s time to build your first NFT collection.

But you may be asking, ‘Why create collections when you can simply upload one individual file’? Well, you can actually upload an individual file, but don’t do that. NFTs receive the most visibility and are best sold as being part of a collection. So even if you don’t have many digital arts to put together to form a collection you can still do it with that single art you have.  Just make different variations of one NFT with individualized colors, shapes, and more. But make sure it forms a collection.

To create a collection, follow the steps below:

1. Go to your profile and select “My Collection.”

2. Hit “Create Collections” to start a new one.

Your new collection will be composed of the logo image, the featured image, and the banner. But at this point you can now add anything you want to mint. And that is the beginning of the actual minting process.

Step 4: Mint (Upload) Your NFT

Once you make your first collection you have done the difficult part of the job. The rest is easy. It is just as simple as uploading a JPEG file. And that is all the talk about minting that you have been hearing. So just follow the steps below:

  1. Open the collection you just created.
  2. Click on Add Item.
  3. Upload an NFT and give it a name.
  4. Fill in the properties, levels, and other descriptions for the item (they are all safe explanatory)
  5. Click Create when finished

That’s it! You are now a proud owner of NFTs in one of the most popular marketplace in the world. You can see your NFT in your collection. And others on the platform can see it as well. You could choose to keep it for display or sell it to the highest bidder.

How Much Does It Cost to Mint an NFT on OpenSea?

The amount of Ethereum you’ll need to get started with minting an NFT varies based on the gas fee needed at the time. In case you don’t know what we mean by gas fee, it is how much Ethereum you need to pay the miners of the cryptocurrency.Someone said you can think of gas fee as the tip you give to your waiter at the end of the meal. Or the commission you pay to use certain platforms to carry out your service.

Unfortunately, the gas fees aren’t controlled by OpenSea. Rather they are set by based on supply and demand for the computational power of the network needed to process smart contracts and other transactions.

So, the amount of money you’ll need to invest initially depends on the two gas fees associated with registering your account and allowing access to the item. The current service fee in OpenSea is set at 2.5%. And the good thing is that you don’t need to pay that upfront.
