NFTs became a part of pop culture, with celebrities like Snoop Dogg, Eminem, and many more joining in the hype. Overcoming the "crypto winter", NFTs have had a solid entry in 2022 with almost $7 billion volume in January. We also have some international brands like Nike and McDonalds, who jumped on the NFT bandwagon this year. 

Are you interested in getting in on the hype and making some sweet decentralized currency? Congratulations! You are in the right blog at the perfect time! This is the ideal opportunity for you to launch your own NFT project, and Niftyjobs is here to help you out with the entire process. This article will have a detailed discussion on how you can create, mint, and sell your own NFTs for free and fully capitalize on the hype.

What is an NFT?

NFTs (non-fungible tokens) are a digital ledger stored on a blockchain that you can use to prove ownership of digital or physical assets such as artwork, music, real estate, or digital collectibles. Mentioned as the word of the year in 2021 by Collins Dictionary, NFTs have gained worldwide popularity by introducing a decentralized authentication certificate. NFTs act just like other cryptocurrencies, except they are not mutually interchangeable like Bitcoin or Ethereum. For example, you can exchange one Bitcoin for another without changing value, but it's not the same for NFTs. You can imagine NFTs as trading cards that we used to collect as kids, each trading card has a different rarity, and you wouldn't exchange your rare cards with some common card, would you? Similarly, every NFT is unique, and you can not exchange some random NFT with a CryptoPunk or a common CryptoPunk with a rare one without a change in value.

The Polygon Blockchain

Formerly known as Matic Network, Polygon is a scalability and framework solution for Ethereum, the most popular blockchain. Polygon is an Ethereum-native blockchain and can operate with all of Ethereum's present and upcoming infrastructures. Polygon users get access to a host of major scaling and infrastructure solutions such as Layer 2 solutions, hybrid solutions, sidechains, data availability solutions, and so on. Apart from that, with Polygon, you get an extra edge over Ethereum NFTs due to its high transfer rate, industry low transfer fees, and compatibility with all types of blockchain networks.

Why Create Your NFT on Polygon?

You can easily mint, purchase and transfer the ownership of your NFTs for free on the Polygon blockchain. For example, if you are doing a promotional giveaway or starting on NFT creation, Polygon's features make it very useful. What's even better? You can sell NFTs on Polygon blockchain at Ethereum valuations as the native token MATIC holds its value well in the crypto crash. The Polygon blockchain is also very suitable for dynamic NFTs that morph with user interaction because of the low gas fees. Also, it is very simple to create a semi-fungible token for free where several people can own one item. Whether you are just a budding NFT artist, game developer, influencer, or just an NFT enthusiast, there is no entry barrier for getting started with your project on Polygon. 

How to Create NFTs For Free?

Faucets are sites that provide you with free tokens to start your project. Two faucets you can use to get some MATIC in your wallet are and Visit these sites and provide the necessary information, such as your MetaMask ID, and you will receive some MATIC tokens in your wallet within a few minutes.

Now that your wallet is all set up with some tokens in it, the next step is to connect it to your OpenSea account. This step is quite simple; you need to click on the wallet symbol on the top right corner of the OpenSea homepage and select the MetaMask wallet. Provide the required details, and you will have your MetaMask connected to OpenSea.

4. Minting the NFTs

Now that you have completed all the prerequisites, the next part is minting the NFT. Select the "Create" option on the top right corner, and you'll be redirected to the NFT minter.

You first need to upload the media you want to be converted to an NFT. It can vary from an image, music, animation, or even the proof of ownership of something tangible. 

Next, switch the Blockchain to Polygon and provide the needed information.

Click on the create button, and your NFT will get minted in the next few minutes.
