"NFT" was among the most searched terms in 2021, even crossing other buzzwords in Google searches, such as Dogecoin, blockchain, and even Ethereum. 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 NiftyHype 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?

In this guide, we use the OpenSea NFT minter to mint free NFTs on Polygon. Despite all the controversies surrounding Opensea, it has the most versatile and easy-to-use NFT minter. The interface is very beginner-friendly, and OpenSea mostly covers the minimal fees required to mint a Polygon NFT. 


1. Setting up The Wallet

Before logging in to OpenSea, you need a crypto wallet that supports Polygon. If you have a wallet set up already, you can skip this step and go directly to the next one. While you can use a wallet from any provider, MetaMask is one of the best free wallets available and recommended by most NFT developers. Don't want to download or install any extra applications? Just add the wallet extension to your Chrome browser, and you are good to go.

As the Ethereum gas fee is reaching the moon, we need to switch to Polygon Network for creating our NFT. For this, you need to click on the Ethereum Mainnet dropdown and click on Add Network. You need to fill in the following information on the next page and save it.

Network Name: Matic Mainnet

New RPC URL: https://rpc-mainnet.maticvigil.com/

Chain ID: 137

Currency Symbol: MATIC

Block Explorer URL: https://polygonscan.com/


2. Acquire Some MATIC

After setting up your wallet, you would need some MATIC in your wallet for minting NFTs on the Polygon blockchain. While you can buy MATIC and transfer it to your wallet from platforms like Coinbase, you can also get started free using faucets. 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 Macncheese.finance and Matic.supply. 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.

3. Create an Account on OpenSea

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.

Congratulations, you have successfully minted your first ever NFT on the polygon blockchain! However, if you want to sell it and make money, you can list it on OpenSea itself or other Polygon-supported marketplaces.

Some Successful NFT Projects on Polygon Network

For creating NFTs that sell, you can take inspiration from projects that have already made their name in this space. While directly copying a project will not benefit you much, you can research them to discover what made them popular. Factors such as roadmap, community, development team, social media presence, etc., contribute greatly to a project's success. Let's look at some popular NFT projects built on the Polygon Network.


1. Crypto Unicorns Multiverse

Unlike most NFTs, Aavetogotchis grow with player interaction, making Ethereum blockchain too expensive for users. Aavetogotchis, come in six different traits assigned to them randomly using the Chainlink VRF.

5. The Red Village Champions

The Red Village Champions is a competitive play-to-earn game on the Polygon blockchain where players can collect, summon and battle Champions.

Other Blockchains to Mint NFTs

While Polygon Network is a great blockchain for your NFT project, there are also other blockchains that you can use. Every blockchain has its own set of benefits and drawbacks, out of which you need to choose the best match for your requirements. When choosing a blockchain, you need to keep in mind features such as transaction speed, transaction cost, smart contract functionality, security, and more.

Final Say

As compared to Ethereum, Polygon is a relatively new ecosystem. However, the Polygon blockchain is so cheap to use that it's basically free. The utility that you get on the Polygon blockchain at such a low price has the potential of attracting a lot of customer demand. If you can afford the Ethereum gas fee and only aim for short-term success, you should choose Ethereum. But if you are looking to make your NFT project sustainable in the long term, the Polygon blockchain is the one you should go with.
