How to Mint an NFT

OpenSea is the largest marketplace for buying and selling NFTs in the globe. It stands head and shoulders above the dozens of comparable services, with over a million transactions per month. Perhaps you looked through their product categories and wondered, “How can I make an NFT?” If that’s the case, this essay is for you.

We’ll show you how to create your first piece of artwork, or any other type of digital asset, on OpenSea.

How to Mint an NFT with OpenSea

Today, there is no better venue to sell art than on OpenSea. There are numerous advantages to doing so. For example, you can increase your visibility while still maintaining control over your work.

Plus, every time someone resells your NFT, you get a commission.The more your NFT appreciates in value after resale, the more money you make.

To mint NFTs on OpenSea, you’ll need to purchase Ethereum, set up a crypto wallet, link it to your OpenSea account, and upload your NFT. Here’s a step-by-step guide to completing all of these tasks.

Purchase Ethereum

Ethereum is the most widely used cryptocurrency today, second only to Bitcoin. In fact, it is used to buy and sell most NFTs. To obtain Ethereum, you must first open a crypto exchange account.

If you don’t already have one, Coinbase, the most popular crypto exchange site, is a good place to start. You may purchase and sell cryptocurrencies like Ethereum from here.

Make a Cryptocurrency Wallet

After you’ve purchased some ETH, you’ll need to construct a crypto wallet. On OpenSea, you’ll utilise this wallet to buy and sell NFTs.

MetaMask is one of the easiest wallets to use, and it’s the one that OpenSea recommends. It’s a browser extension that works best with Google Chrome and Brave. You can use it to store Ethereum and Ethereum-based tokens like NFTs once you’ve installed it.

Connect your OpenSea wallet to your OpenSea account.

With a few simple steps, you can connect your wallet to OpenSea:

  1. In your browser, open the MetaMask plugin and input your password to unlock it.
  2. In the same browser, go to and click “Profile” in the top-right corner.
  3. You will be prompted to connect your cryptocurrency wallet on the website. MetaMask is the best option.
    Accept the terms of the agreement.
  4. To verify your account, enter your email address and username.
  5. Follow the instructions in the email you received for verification.

That concludes our discussion. You’re now ready to create your first NFT. If you’re using a different crypto wallet, skip to Step 2 and choose the appropriate choice in Step 3.

Make Your Very First NFT

You’re now ready to produce your first NFT after setting up a wallet and connecting it to OpenSea. Creating a collection is the best approach to do so.

Why make collections when you can just upload a single file? NFTs, on the other hand, get the most attention and are best sold as part of a collection. You can construct different variations of a single NFT by changing the colours, forms, and other details.

  1. Follow the steps below to make a collection:
  2. Go to your OpenSea profile and select “My Collection” from the drop-down menu.
  3. To start a new collection, click “Create.”

This collection can be viewed as a digital portfolio of your work. You can share your most recent designs, memes, or even drawings of cute kittens. You might be astonished to learn that “cryptokitties,” stickers of cats that are purchased and sold for tens of thousands of dollars, have their own category on OpenSea.

Make the NFT.

It’s simple to add an NFT to your first collection once you’ve completed it. Simply follow the instructions outlined below:

  1. Open the new collection you’ve made.
  2. Select “Add New Item” from the drop-down menu.
  3. Give your NFT a name and upload it.
  4. Fill in the item’s attributes, levels, and other information.
  5. When you’re finished, click “Create.”

Check Your Storage

The storage problem is another something to consider before uploading your first NFT. Technical problems can occur when NFTs are kept on centralised servers. Instead, keep them on the blockchain or on systems like Arweave and IPFS.

On OpenSea, how much does it cost to mint an NFT?

Before making their first transaction, all first-time vendors must pay two fees to OpenSea. These fees aren’t set in stone, and if you know how, you can manage them. So, what exactly is the secret?

These fees, on the other hand, are transactions that take place on Ethereum’s blockchain. As a result, creating them necessitates some processing power. You pay a “gas fee” to compensate for that energy. The cost may be more or lower depending on the current gas price.

The first charge to set up your account and begin selling might range from $70 to $300. The second transaction, which gives OpenSea access to your NFTs, should cost between $10 and $30.

Naturally, you’ll want to set up your account on days when petrol prices are lower to save money and pay the lowest fee. Fortunately, there is a service called Gas Now that allows you to keep track on gas costs. The days when the number goes below 100 are the best days to pay the fees.

On OpenSea, fees are paid in Ether. This means that the price varies depending on the crypto’s current value in relation to your currency.

You must additionally pay OpenSea 2.5 percent of the NFT price when it sells, in addition to the two fees for the initial sale.

After the first sale, OpenSea does not impose fees for minting NFTs.

To sell NFTs, you can utilise a number of payment tokens. The following cryptocoins are recommended by the platform:

  • Ethereum
  • WETH
  • DAI
  • USDC (cryptocoin that stands for US Dollar Coin, not to be confused with US dollar)
