The NFT market is huge and rapidly growing. There are currently over 600 NFT-based projects that have been launched globally, with many more in the pipeline. In 2017, the NFT market was valued at $4 billion, and it is expected to grow to $35 billion by the end of 2022, and to over $80 billion in 2025. NFT is a transformative technology that's going to completely change the way we look at digital assets. It's not just about digital cats, cryptokitties or digital art, it's about how we will be able to tokenize anything and everything with the power of the blockchain in the near future. The great thing about NFTs is that they will be a very cost effective way to do this. In this article, we’ll discuss what is an NFT, how to create your own NFT collection, how to mint NFTs for free, and how to mint your NFTs on OpenSea.

What is an NFT?

An NFT is a digital asset that is unique and can be distinguished from other assets. This can include a digitally encrypted token or a token that has a different value or function. NFTs are powered by Ethereum smart contracts, thus making them a digital asset. NFTs are used as a medium of exchange in various applications and as such, they are also referred to as non-cryptographic tokens. They are designed to be used across multiple platforms and can represent anything from collectibles to in-game items.

How to mint NFTs for free?

After creating an NFT, the next step is to mint it. Minting an NFT is a process of generating a new token based on the existing one. This can be done by calling the mint method of the NFT contract which takes a single argument called amount, which indicates how many tokens should be created. This method returns the new token ID which is used in all further transactions with the new token. The minting process is based on the commitments to sell a certain amount of tokens in exchange for Ether. For example, if you want to mint 0.2 ETH worth of tokens, you must commit to selling 20% of your tokens in exchange for Ether. The more tokens you will have, the less % you have to sell in order to mint new ones.

Here is how you can mint NFTs for free.

  1. Create the NFT contract
  2. Transfer the token ID and distribution rights to a wallet address
  3. Mint NFTs with the mint function of the wallet

How to mint your NFTs on OpenSea?

In order to mint your NFTs on OpenSea, you will need to complete the following steps.

  1. Create a new asset on the platform
  2. Go to the “Mint” tab of your newly created asset
  3. Select the token you would like to mint. There are three options for minting:
    • Create a new token by minting against a ERC721 token representing an existing digital asset. This allows you to mint new ERC721 tokens on OpenSea that represent something that already exists in the world outside of their platform. This is useful if you have a digital asset elsewhere and want to use OpenSea as a marketplace to sell your asset

    • Create a new token by minting against a quantity of another ERC721 token that represents an existing digital asset or a fraction of it. This allows you to mint new ERC721 tokens on OpenSea that represent something that already exists in the world outside of their platform as well as whatever quantity of it that you choose. This is useful if you want to sell fractions of an existing digital asset on OpenSea, rather than the full amount at once

    • Create a new token by minting against ETH. This allows you to create an entirely new ERC721 token on OpenSea without needing another asset to back it. This is useful if there is an entity (such as a company or community organization) that you would like to represent with an ERC721 token, and which doesn’t already exist elsewhere in the world (e.g., as a registered trademark)

  4. Choose whether you would like to use your own contract (if you have one), or use OpenSea’s contract (if your token is going to be sold on OpenSea). If you selected “Use my own contract,” please enter in your contract address in the appropriate field and click “Next Step.” If you have selected “Use OpenSea’s contract,” you will be taken directly to the next step where you can enter in your contract address. Once done, click “Next Step”

  5. Enter in your Ethereum address where your newly minted tokens would be sent, if using Ethereum. If not using Ethereum, leave this blank and click “Next Step”

  6. After you click “Next Step,” you will be taken to a page showing the contract address you entered, your Ethereum address (if using Ethereum), and a “Send Ether” button. Click the button to send your minting fee in ETH to OpenSea. When the transaction is complete, you will see a “Transaction Successful” message

  7. You can now view your newly minted NFTs in your asset dashboard


The future of NFTs is quite promising. The fact that they can be used to solve some of the problems with the blockchain technology is a huge step forward. We’re still in the early stages but as adoption of this technology grows, so will the number of NFTs.
