Creating Your NFT Art

If you want to mint an NFT on OpenSea, you must have the artwork first. Here’s a step-by-step guide to creating an NFT digital art piece:

Know Your Audience

If you want to sell your NFT, you need to know who you’re selling to first – this will help you develop marketable NFT concepts. Your NFT’s concept informs everything about your art, especially its visual style and title.

Research your target audience to discover what kind of art appeals to them. For example, a younger, internet-savvy audience is more likely to love “memeable” NFT art concepts. Once you know what your audience wants, develop an NFT concept that appeals to them.

Don’t skip this step, even if you’re creating an NFT for yourself. Define what kind of art appeals to you and create work based on that.

Create Your Art

With a concept in mind, it’s time to create. Boot your creative software up and make the art piece based on the concept you came up with.

If you’re planning to create a large NFT collection in the vein of Bored Ape Yacht Club, use a generative art script to speed up the process.

Save The Art Into Digital Files

Save the digital art files on your computer or in cloud storage. Make sure you have backups in case your computer crashes.

Minting And Selling Your NFTs On OpenSea

Now that you have an NFT piece, you can mint and sell it. Here’s how:

Make A Cryptocurrency Wallet

Create a cryptocurrency wallet if you don’t have one yet. Popular NFT wallets supported by OpenSea include MetaMask and Coinbase Wallet.

Sign Up To OpenSea

Next, connect your wallet to OpenSea to create an account. Follow the instructions and add your profile information to become an OpenSea member.

Upload The NFT Collection

After logging into OpenSea, click the “Create” button on the homepage to visit the NFT creation page. Upload the digital files you saved beforehand and fill key details out, like the NFT’s title and description. You can also add extra information about the NFT and whether it includes any bonus content.

If you have several NFT pieces as part of a collection, you can upload them on the same screen. Simply create a new collection and upload the rest of your pieces.

List Your NFTs For Sale

Once everything’s uploaded, click the “Sell” button on the homepage to enter the NFT listing page. There, choose between three sale options:

  • Fixed-price sale
  • Highest bidder auction
  • Declining price auction

Additionally, you can set the sale’s time limit, starting price, and royalty rates. Before confirming your NFT listing, make sure you have enough ETH in your wallet to pay the service fee when your NFT sells.

Buying NFTs On OpenSea

OpenSea boasts over 80 million NFTs, so there’s bound to be an NFT piece you like. Here’s how to find and buy NFTs on OpenSea:

Make A Crypto Wallet

As when you mint NFTs, you need to create a crypto wallet. Sign up for a MetaMask wallet or any other crypto wallet supported by OpenSea. Ensure you have crypto in your wallet before making your purchase.

Sign Up For An Account

Connect your crypto wallet to OpenSea and fill your profile information in to create an account.

Browse For NFTs

Explore OpenSea’s marketplace to find NFT pieces that catch your eye. If you don’t know where to start, browse the NFTs listed in the site’s top rankings.

Make A Purchase

Depending on the seller, you typically have two ways of buying NFTs on OpenSea:

  • Fixed-Price Sales: For a fixed-price sale, check the price and click “Buy Now”. From there, just pay the gas fees to become the proud owner of a new NFT piece.
  • Auctions: In NFT auctions, click the “Place Bid” button and input your bid amount. Once you’ve made the offer, just sit back and wait until the auction finishes. However, if you really want that NFT, we suggest keeping an eye on the page and upping your offer every so often.


OpenSea is one of the best NFT marketplaces available thanks to its user-friendly interface and low minting costs. It boasts 80 million NFT pieces, meaning there’s likely something for every collector.
