Many creators have sold NFTs for thousands, even millions, of dollars, and some businesses have jumped on board to produce and invest in digital tokens. The future for NFT investment and creation appear to be better than ever.

The procedure of creating NFT is somehow sophisticated, and it may be tough for those who are new to NFT creation. Fortunately, the OpenSea marketplace’s NFT creation tool provides a more simple option.

With over 1.2 million users and 80 million NFTs, OpenSea is currently one of the most popular NFT marketplaces. It simplifies the buying, trading, and minting procedures.

We will provide a full, step-by-step guide on how to mint NFTs on the OpenSea marketplace.

  • Choosing a Non-Fungible token  (NFT) Marketplace
  • Getting started with your NFT Wallet
  • Connecting your OpenSea Wallet
  • How to Start Creating Your NFT Collection
  • How to make your first  (NFT)

Step 1: Select an NFT Marketplace

Although this post will focus on, there are number of other NFT marketplaces where you can mint, buy, and sell NFTs. Because all NFTs are publicly available on the blockchain, several marketplaces show them at the same time and track their sales and pricing.

As a result, after you’ve minted and sold an NFT on OpenSea, it’ll be available on all other marketplaces as well.

The following parameters must be considered while determining the appropriate marketplaces for us to start minting:

NFTs come in a number of token forms, and different marketplaces support different types of tokens.

Tokens standards

NFTs are available in various of token forms, and different marketplaces support various token types. ERC-721 is the most widely used token standard, and it was used to create the first NFTs. Every ERC-721 token is rare and unique, giving consumers the opportunity to own a digital asset. ERC-721 tokens make up a large portion of the OpenSea marketplace.

Another standard, ERC-1155, allows authors to create a limitless number of both fungible and non-fungible tokens using a single smart contract. To take advantage of this smart contract capability, the OpenSea creation tool employs the ERC-1155 standard.

Sellers on OpenSea only have to pay a single initialization cost for their collection if they publish several NFTs with the same contract.

Wallet Compatibility

Finding a marketplace that supports your chosen crypto wallet is good if you already have one. OpenSea now supports 15 wallets, including popular options such as Coinbase and MetaMask. If you don’t already have an Ethereum wallet, we recommend following the instructions in the next step to install MetaMask.

User verification

Because anybody can turn any digital material into an NFT, user and content verification helps to ensure that NFT collections are original and authentic. Accounts of well-known firms or individuals, as well as accounts with high fraud risks, are verified by marketplaces like OpenSea.

Verification helps in the reduction of copyrighted NFT sales and the prohibition of manipulative NFT trading techniques.

Token Fractionalization

NFTs, especially rare collectibles, can be very expensive and out of reach for most people. However, some marketplaces offer token fractionalization, which allows users to purchase a portion of an NFT.

Sellers profit from selling assets faster on these marketplaces since they can sell them in more cheap chunks rather than waiting for the highest bidder to buy the entire NFT. Similarly, buyers benefit from lower costs and are more likely to purchase NFT segments due to their affordability.

Other Benefits

Fees and minting rates vary according on the marketplace. Discounts, greater royalties, and referral bonuses are all possibilities. To figure out which marketplace incentives are the most beneficial to you, you’ll have to check a few out and evaluate which ones have the most useful features.

Step 2: Set up your wallet

Users must first create an Ethereum wallet to store their cryptocurrency and NFT assets before minting an NFT. Users of OpenSea can choose from a variety of wallets, the most popular of which being MetaMask.

Add MetaMask Chrome extension to your chrome browser and create an account to build a MetaMask wallet. After entering a password, you will be given a 12-word Secret Recovery Phrase.

MetaMask requires you to save your recovery phrase in a secure location and keep it hidden from others. You must supply this phrase if you ever need to recover your wallet, and anyone who knows your recovery phrase will be able to access your account and move your funds.

Step 3: Connect Your Wallet to OpenSea

After installing the MetaMask chrome extension, follow these steps to connect your wallet to OpenSea:

  • Several wallet alternatives will be listed on the website. MetaMask should be selected (unless you prefer a different wallet).
  • To finish connecting your wallet, accept the terms and conditions.

Step 4: Create an NFT Collection

You can create your first NFT after setting up a wallet and connecting it to OpenSea. Although you can be create and publish NFTs all alone, we suggest minting them as part of a collection because they often generate more views and sales.

Follow the steps below to make a collection:

  • Go to your OpenSea profile and select My Collection from the drop-down menu.
  • To create a new collection, click Create.
  • Add a logo, a featured image, and a banner image to your page.
  • Choose a category, give your collection a name, and write a description.
  • Select the resale cost that will be deducted from all future NFT resales.
  • Choose a blockchain and acceptable payment methods; Ethereum is a good choice for both.
  • Click Create after selecting a display theme.

You can publish related NFTs or different variations of a single NFT in your collection, each with unique properties. This collection can be viewed as a digital portfolio of your work. You can use your most recent designs, memes, or even drawings of kittens.

Step 5: Mint your first NFT

Once you’ve created your first collection, it’s simple to add an NFT to it. Simply follow the instructions outlined below:

  • Open the new collection you’ve made.
  • Select Add Item from the drop-down menu.
  • Give your NFT a name and upload it.
  • Fill in the qualities, levels, and other properties.
  • When you’re finished, click Create.

You must pay a one-time initialization cost and grant OpenSea access to your NFT items for your first NFT listing. After that, you’ll get a digital signature, which OpenSea will publish the NFT on Marketplace.


It’s as simple as that. Following these simple procedures, your NFTs should be available for purchase on the marketplace. You can share the link to your collection with others, add new NFTs, and even use your NFTs in the metaverse from here.
