How to Transform Your Art Into NFT: Minting on OpenSea

If you have impressive artworks in your possession and think about how to translate them digitally, you are in the right place. Our digital experts will provide you with all the necessary information on how to create and mint NFTs. There are plenty of marketplaces for you to start your NFT minting journey, yet our focus is the OpenSea. It is the largest decentralized platform connecting millions of sellers with potential buyers. 

OpenSea offers you around 150 cryptocurrencies as a payment option. Moreover, it is considered the most user-friendly platform due to its knack for streamlining the minting process. So, let’s delve deep into this fast-emerging industry by following our step-by-step guide.

Connect Your Crypto Wallet

As we have already decided on the OpenSea marketplace for minting your first NFTs, you need to connect your crypto wallet. OpenSea supports a broad range of wallets, both for desktop and mobile use. Our recommendation is the most popular and user-friendly digital wallet– MetaMask. So, visit the webpage, find the ‘wallet’ button in the top right corner and choose MetaMask wallet. 

You should install MetaMask Extension for your browser. It supports the following browsers Chrome, Firefox, Brom, and Edge. You can add your already existing wallet or create a new one. 

Beware: Never ever disclose your Secret Recovery Phrase or Password!

As you have already installed the MetaMask extension, go back to and link it to your wallet. Now let’s understand how you can create your first NFT collection on OpenSea.

Set up a New OpenSea collection

It’s time to create your first collection, as NFTs get the most visibility as being part of a collection. Find the ‘My Collections’ button on the top right, then select the ‘‘Create a collection’’ button.

Begin Minting Your First NFT

You must set images for your collection such as logo image (350 x 350 recommended), featured image (600 x 400 recommended) and banner image (1400 x 400). You should also pick a name, add a description for your digital masterpieces, and customize the collection’s URL.

Technically speaking, the Opensea marketplace allows you to mint almost everything, such as artworks, movies, event tickets and even poems. However, your files should match the following requirements: JPG, PNG, GIF for visual files, MP3 for music or audio files, GLB for three-dimensional files and beyond. Once your collection is set, let’s begin minting your first NFT by adding items to it.

Click on ‘My Collection’ then ‘’Add item’’ on the top right corner. Now you can create a new item by uploading your piece of art with a MAX size of 100MB. Create a unique name for your item and write an eye-catching description for it. Potential buyers can read information underneath your uploaded file. Next, fill in the properties for your digital item, like character, name, eyes, etc. You must also add some stats and levels to your NFT.

Now, choose the number of copies you want your NFT to be minted. The final step is deciding on the blockchain. The Opensea platform supports Ethereum, Klatyn, Polygon, and Solana blockchains. Yet, our recommendation is Ethereum as it remains the gold standard for many buyers and sellers.

Click on the “Create” button and you are ready to offer your NFT for sale or keep it for display.

Another feature that makes Opensea the best marketplace is the possibility of the lowest commission fees. Moreover, the marketplace supports more than 150 payment methods.

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

If you are a beginner, that is to say, a first-time seller, you should pay two fees that you cannot control. Each process takes transaction energy, and to compensate for that energy, you have to pay a ‘’gas fee’’. Yet, you can track gas prices as there are days when gas fees are lower. Also, you have to pay between $70 and $300 for your profile initialization. Then the second transaction will cost about 10 to $30.

Moreover, OpenSea charges 2.5% of the NFT price when it sells.
