What is NFT mining?

NFT minting is the process of storing NFT art on the blockchain.

NFT minting is usually done on the NFT market or platform. Some of the popular markets besides OpenSea are: Rarible, Binance and many more.

OpenSea is the market with the largest trading volume, which is why in this article we will look at how to release NFT on OpenSea.

How to create an NFT on OpenSea

To mine your NFT on OpenSea, you can use the instructions below. Make sure to follow these steps carefully as your NFT will be stored on the blockchain forever. For the first steps you need a crypto wallet.

1. Connect your crypto wallet to OpenSea

NFTs are unique digital assets stored on the blockchain. To start minting cash, you need a wallet that can be connected to OpenSea. There are several ways to do this, but we recommend MetaMask, which is a popular option.

You need to connect your MetaMask wallet to the OpenSea Market. MetaMask is available as a cold store and as an extension for Google, Chrome and Brave browsers.

To connect, you can go to the OpenSea website and click on “Profile” in the upper right bar. A new page will appear asking you to connect your wallet.

Connect the wallet to OpenSea

You must complete various prompts to give OpenSea the necessary permissions to use your wallet and funds. A prompt to sign and then a connection screen will link OpenSea to your wallet.

Go to the profile and select “My Group”, then click “Create” to create a new group. The new set consists of the logo image, the intro image, and the logo.

You’ll find several properties to fill in, including a group URL on OpenSea, description, category, and links to your website and social networks.

You will be asked to enter your withdrawal wallet address. Go to the wallet icon and click on the address that will be copied automatically and then paste it into the field.

The newly created items are stored on the blockchain of your choice, but in this case Ethereum is the ideal blockchain. But you can also use another blockchain like Polygon, which is a layer 2 blockchain that helps increase transaction volumes and lower gas fees.

In the next step, you can define payment codes to buy and sell items. After selecting the payment codes, you can click “Generate”.

Your collection is now complete, but it still needs some items, which is the actual minting.

  1. Build your own NFTs on OpenSea
    Now that everything is set up on OpenSea, you can start releasing NFTs with these steps:
  1. Select your group and click “Add Item” on the right side of the page.
  2. Upload your artwork or collection that you want to make an impact.
  3. Add details and description for each NFT (such as the name of your artwork or collection).
  4. Define group specifications and add NFT properties (eg eyes, colors, artist names, etc.).
  5. Add levels and attribute rarity stats to your NFT.
  6. Set whether the item is irrevocable and explicit or sensitive.

After you have created your NFT instrument, you can now put it up for sale as it is now available for sale on the open market. Click the Sell button in the upper right corner of the NFT description page.

The sale process allows you to set the details of the sale, which can be either a fixed price or a limited time auction. In OpenSea, one can set royalties for continuous passive monetization of work over time. Different markets display the corresponding fees for the sale. On OpenSea, the sales service fee is 2.5%.

Now click on “Full List” to allow the market to calculate gas fees based on the level of activity of the cryptocurrency network at the time of listing.

After the NFT is mined and offered for sale, one can start dealing with potential clients.

There are reports of many digital artists making big and easy money by creating NFTs. However, keep in mind that the NFT movement is still in its infancy. The minting and selling of NFTs should not be viewed as a quick profit.

Before you can sell your digital assets, there are some costs involved.
