How to Create an NFT on OpenSea

Creating an NFT on OpenSea is intuitive and easy. You just need to decide what the purpose and genre of your collection is, set up a crypto wallet, choose a blockchain, and list your NFT(s). In this article, we’ll walk through the steps one by one and explain exactly what you need to do to create your first NFT.

Who can create an NFT?

Anyone can create an NFT. Your NFT can be as simple as the media itself, but it can also represent something more. Think of it this way: your NFT can simply be a piece of art, or it can be a piece of music represented by a GIF or a photograph. In the latter example, the NFT is the combination of the representation and the digital item it represents. 

What do I need to create an NFT?

In addition to the NFT itself, you’ll need a crypto wallet to create and mint your NFT. “Minting” an NFT is the process of writing a digital item to the blockchain. This establishes its immutable record of authenticity and ownership. 

Crypto wallets are a foundational tool of web3. Your wallet acts as a private key that allows you to interact with decentralized apps, buy NFTs, and navigate the web3 universe. Each blockchain has specific wallets you can use to transact on them. For example, MetaMask is a wallet used to interact with the Ethereum blockchain, and Phantom is a wallet used to interact with the Solana blockchain. OpenSea is compatible with a wide variety of wallets.

Next, choose a blockchain on which to mint your NFT. OpenSea is currently compatible with the Ethereum, Polygon, Klaytn, Arbitrum, Optimism, Avalanche, BNB Chain, and Solana blockchains, and each of these blockchains has different gas fees associated with transactions on their networks.

Then, you can create your collection. This is the fun part! Decide what your collection of NFTs is all about. Is it artwork, a collection of profile pictures, sports memorabilia, membership to a group, or something else entirely? Once you decide, create your collection by naming it something unique that represents your work and describing it. You’ll also be prompted to choose a category and provide any relevant links to social media.

Once your crypto wallet is set up, you’ve chosen a blockchain, and your collection has been created, you’re ready to mint your NFTs!

Does it cost money to create an NFT?

Sometimes. Depending on the blockchain, creators will need enough cryptocurrency in their wallets to cover the gas fees for the transaction. But, on Ethereum and Polygon, OpenSea offers something called “lazy minting,” a process by which creators can avoid paying gas fees to mint NFTs.

Lazy minting and the OpenSea collection manager allow creators to make NFTs without requiring any gas fees up front. This process works because the item isn’t transferred on-chain until the first purchase or transfer is made from the creator to the first collector. Collections are also free and instant to make. 

What are the step-by-step instructions for creating an NFT on OpenSea?

OpenSea makes it simple and fast to create an NFT.

First, you’ll need to create a collection.

Once you’ve done that, click on the Create tab in the top right corner on the OpenSea website.

Once clicked, you’ll be taken to the NFT item creation page where you can upload the file of your NFT and give it a name and a description. You can also add an external link to your website or social media accounts.

Next, you can add the NFT to an existing collection or add Properties (textual traits that show as rectangles), Levels (numerical traits that show as a progress bar), and Stats (numerical traits that show as numbers). You also have the opportunity to add Unlockable Content which is content that can only be revealed by the owner of the item. We’ll ask you to toggle on a switch here if your NFT contains Explicit or Sensitive Content.

Finally, we’ll ask you to list the supply, which is the number of items that will be created, and the blockchain you’ll be creating the NFT on. This defaults to Ethereum, but you can also choose to mint on Polygon. Once you’re done, just click Create!

Once completed, you’ll see a pop up that indicates your NFT has been created and allows you to share it via link, Facebook, Twitter, or Telegram.

🧠 Q&A

Can something be non-fungible but not an NFT?

Yes! Any completely original item that isn’t interchangeable with another of the same item is non-fungible. So, an original piece of artwork like the Mona Lisa is non-fungible. An item of clothing is also non-fungible because it may be more valuable than another similar item because of who previously owned it or the condition it’s in. But neither of these things is inherently an NFT because a non-fungible token must be recorded on the blockchain. The blockchain functions as a transparent, immutable, permanent online ledger that keeps track of transactions. Therefore, what makes something an NFT is that it is both non-fungible and recorded on the blockchain.

Will we buy things like cars as NFTs on the blockchain in the future?

Very likely, yes! Because NFTs are immutable (which means they’re unable to be changed) and offer sole ownership of an item, they’re a natural fit for purchases that need to be trackable like cars. For example, right now when buying a car, the owner received a paper title. In the future, we can see that being replaced by a smart contract on the blockchain. With a public record of ownership accessible to anyone, the owner can easily and clearly prove ownership of their car, transact with agencies like the DMV, and even sell their car later on.

What makes some NFTs more expensive than others?

The value of an NFT is in the eye of the beholder, but many factors come into play when we talk about value. In larger collections, the rarity of an NFT can increase its value. Some NFTs have qualities, features, or aspects that make them special and therefore desirable. For reference, those qualities are listed on each NFT’s OpenSea page. NFTs with traits that are one-of-a-kind tend to drive higher value than their more common counterparts. An NFT made by a well-known creator or artist will also drive more value for the same reason an original Monet is worth more than your first grader’s macaroni necklace. No shade to your first grader, by the way. And finally, utility is something that can affect value. If an NFT grants its owner access to something exclusive or desirable, it’s likely to be more valuable. These are just three things that can make an NFT more expensive, but there are plenty of other elements at play that can affect the price and resale value of an NFT.
