The most owned NFT today is in the form of image or photo art. These artworks can be found in several marketplaces such as Opensea, Rarible, Magic Eden, Solanart, and other NFT marketplaces.

How to Mint an NFT on Opensea

What is NFT minting? Minting an NFT is the process of printing digital artworks/NFT into a token. The token is then recorded and stored in the blockchain. Your name as the NFT creator will be recorded in the blockchain as proof of NFT ownership. Likewise with the name of the buyer who bought your NFT artwork. In other words, minting NFT is claiming ownership of NFT.

Because NFT uses blockchain technology, you need a crypto wallet to start minting an NFT. There are several wallets you can connect to, but the most popular is Metamask. Here are the steps for minting NFT in Opensea.

1. Create a crypto wallet

The most popular wallet used in Opensea is Metamask. To create it, you can visit the Chrome Extension on your PC then download and create a wallet. Make sure your secret recovery phrase is stored and kept confidential. It’s a good idea to take notes on paper or in a notebook so you don’t lose them.

2. Visit the marketplace and connect the wallet

To access Opensea, you don’t need to fill in your personal data. You need to connect your wallet by clicking the wallet icon on the top right and then selecting Metamask. Your wallet will be directly connected to Opensea. There are several other wallet options available on Opensea such as Coinbase, Phantom, Dapper, Fortmatic, and other wallets.

3. Click the “Create” icon at the top right of the website

To start uploading your artwork, you can follow these steps:

  1. Click Profile, then select My Collection to create your NFT ‘playlist’. You can skip this step if you only want to print one NFT.
  2. Click Create at the top right. You will be asked to sign an agreement that you will follow the rules at Opensea. This signing does not cost money, so you can click it immediately. Then a page like the one below will appear.

5. You can fill in the Collection that has been created or it can be left blank.

6. You can also fill in Properties that can later function as filters to search for your artwork. For example, your artwork depicts a lion wearing a hat on the beach. Then the properties are character-lion, setting-beach, and accessories-hat.

7. In the Level column, usually use Collection to sort the level of your artwork. The higher the level, the more expensive the price.

8. You can also add Unlockable Content if the artwork is not for the public. And add Explicit Content if the artwork contains sensitive content.

9. Select the blockchain. Since you are using Metamask, the available blockchains are Ethereum and Polygon.

💡 The default blockchain on Opensea is Ethereum. Currently, you can mint NFT with other blockchains such as Polygon, Klaytn, Solana, Optimism and Arbitrum.

10. Click Create.

Yay! You have successfully created your first NFT!

After following the steps above, it means that your artwork is uploaded on Opensea. But other users won’t be able to buy your artwork because it has not appeared on Opensea page yet. You must sell it to make it available for purchase by other people.

4. Sell NFT

To sell your artwork on Opensea, you need to follow these steps:

1. Go to Profile and select the uploaded NFT.

How Much Does it Cost to Mint an NFT?

Opensea currently allows its users to make NFTs without paying any upfront gas cost. This is because Opensea has enabled the lazy minting system on the Ethereum blockchain. Lazy minting is the process of delaying the payment of the gas fee.

When you lazy mint, you can issue NFTs and sell them on Opensea. But actually, your NFT has not been recorded in the blockchain so this process does not use blockchain resources. Your digital works, which are standard ERC-1155 tokens, are stored on a centralized server.

The NFT will be minted when your NFT is sold. The minting fee will be included in the selling price so the buyer is responsible for covering all the gas costs.

However, not all activities on Opensea are gas free. When using the Ethereum blockchain on Opensea, some activities require a gas fee, such as when sellers accept NFT quotes, transfer NFTs to other users, purchase NFTs, cancel listed NFTs, and so forth.
