Minting your own NFTs on Polygon is a great way to create and own your very own digital assets. By following a few simple steps, you can easily mint your own NFTs on the Polygon network.

Minting non-fungible tokens (NFTs) on the Polygon network is a simple process that can be completed in just a few steps. Whether you’re a seasoned blockchain user or new to the space, Polygon makes it easy to create and mint your own NFTs.

In this blog post, we’ll walk you through how to mint your own NFT on Polygon and what you need to get started. So let’s get started.

How To Mint NFT On Polygon? 2022

What is Polygon NFT?

Polygon NFT is a relatively new technology that is starting to gain traction in the networking world.

Copy the contract address from our transaction receipt to be used in this line of code:let instance = await“YOUR_CONTRACT_ADDRESS_HERE”)

It will return undefined but if we type instance it should output our contract ABI. Now we can call the mint function. We will need a contract address in which to send the NFT and our IPFS URI from earlier in the format: ipfs://YOUR_HASH_HERE


It’s important to note that the mint function is being called by the address that deployed the contract because that is the one we logged into the Truffle Console with by default. The address we placed in the code above is the recipient of the NFT.

If all went well with our code above, we shouldn’t see any errors after we hit enter! We now know our contract works and we are able to mint an NFT from it.

You should have a directory structure that looks likeMacBook-Pro:allcode-polygon-nft joelgarcia$ ls -ltr total 1720 drwxr-xr-x 3 joelgarcia staff 96 Dec 3 18:01 test drwxr-xr-x 3 joelgarcia staff 96 Dec 3 18:01 scripts -rw-r–r– 1 joelgarcia staff 572 Dec 3 18:01 hardhat.config.js drwxr-xr-x 3 joelgarcia staff 96 Dec 3 18:01 contracts -rw-r–r– 1 joelgarcia staff 467 Dec 3 18:01 drwxr-xr-x 385 joelgarcia staff 12320 Dec 3 18:01 node_modules -rw-r–r– 1 joelgarcia staff 860814 Dec 3 18:02 package-lock.json -rw-r–r– 1 joelgarcia staff 220 Dec 3 18:02 package.json -rw-r–r– 1 joelgarcia staff 335 Dec 3 18:05 allcode-polygon-nft.iml

The test folder is for our test scripts. The scripts folder is for our deployment scripts. The hardhat.config.js is where we’ll configure the version of solidity, network, and the contracts.

For example, if you aim to produce 10,000 pieces of art, you’re going to require quite a significantly larger number of unique layers than if you solely set out to create ten.

Exporting the Files

Once you have designed all your layers, the next part of this initial step is to export each layer into separate files. We need all layers separate and in individual files as this will allow our engine to combine these and generate unique art pieces.

Exporting the files is relatively straightforward, and if you’re also working with Photoshop, all you need to do is click on the ”Files” button at the top of the interface. Following this, navigate to ”Exports” and click on ”Layers to Files”.

This will export all your individual layers into separate files.
Now, all that remains for the first step is to sort these into separate folders.

So, with no further ado, let’s get right into the process and start with creating art layers that we can feed right into the NFT engine!

However, if you’d rather watch videos explaining the complete process, then watch the following three clips from the Moralis YouTube channel:

Step 1: How to Mint 10,000 NFTs – Creating Art Layers

The art in these NFT collections is computer-generated pieces that consist of a combination of different art layers. Depending on what you intend for your collection, these layers can vary; however, to name a few, they can be backgrounds, clothing, eyes, noses, accessories, etc. Thus, the first step in our process is to create these layers that we can use later to generate unique digital art pieces.

If there is a comma, then OpenSea will not display the NFT properly.

Now we can add this file to IPFS using the same command as last time; we just need to replace the file name with @nft-metadata.json.

Excellent! We now have our metadata pinned to IPFS which has a link that points to our already pinned image. We’ll copy the Hash in the output to use later.

Setting Up MetaMask

In order to interact with the Polygon Network and to pay any transaction fees, we will need to set up a Web3 wallet. We will use MetaMask to do this. It is installed as a browser extension and allows us to connect to Decentralized Apps (dApps).

Let’s head over to and download the extension for our browser.

Here you can see an example.

By Freezing your metadata, you will permanently lock and allow OpenSea to store it on decentralized file storage. ​​This means, your item will be safely stored and will never be lost or missing. To understand this better, I recommend you check the article I made on Rarible.

Now, it’s very important that you have the Matic network chosen on your wallet. To do that, just click on the dropdown button right on the top of your wallet and sellect Matic.

If that option is not showing for you, this means you have to set it up. I’ll also include a link in the description which explains how to do that. It’s really really simple!

Just sign the message and the freezing process will start.

It usually takes a few minutes, but it eventually goes through.

It is an alternative to traditional routing protocols, such as OSPF and rip, and offers a number of advantages over these older protocols.

With Polygon’s blockchain, you can now enjoy fast and secure transactions with Ethereum-based currencies like ETH without paying high fees. Plus there are no more worries about losing your funds.

One of the main benefits of polygon nft is its scalability. It can handle large amounts of traffic without any problems, making it a good choice for networks with a lot of traffic.
Polygon nft is also relatively easy to configure, which makes it a good option for networks that are not very familiar with networking protocols.

Overall, polygon nft is a promising technology that is worth considering for your network. It offers a number of benefits over traditional routing protocols and is scalable and easy to configure.

While you could opt for a vast array of wallets, your best bet would be to download and install MetaMask since it is by far the most popular and robust wallet around.

Send Ethereum to your crypto wallet

Send/withdraw your ETH to your new MetaMask wallet from your exchange account. To do this, you will need the public address of your new ETH MetaMask account, which you can find at the top of the MetaMask popup when you click on the plugin icon.

Sign up for an NFT marketplace using your wallet

Next, it’s time to sign up for an NFT marketplace. These marketplaces are the gateway to participating in the purchase and sale of these digital assets, as well as where you can mint your very own NFT.

What is the Polygon Blockchain?

Polygonis a layer 2 solution for correcting the inadequacies of the Ethereum blockchain, which include transaction processing speed and high transaction charges. It is poised to make blockchain technology easily adoptable and more secure.

Imagine you wanted to get coffee at a shop in town but you find the queue discouraging and you have got to pay for parking all the while you are on the queue. But you don’t have a choice because that’s the only coffee shop that serves the combination of flavors you like.

Now, what would you do if a new shop opens and sells the same combination of flavors you like and there are enough baristas processing orders and brewing coffee so you can have your steamy coffee right in time? Bear in mind that you would also save on parking fees as there are no queues and delays.

Feel free to choose any name and location on your file system. Open up a terminal and navigate to the newly created folder.

Next, we will install the following Node.js dependencies:

  • Hardhat and Hardhat-Ethers, a development environment for Ethereum (and Ethereum compatible blockchains like Polygon).
  • OpenZeppelin, a collection of smart contracts featuring standardized NFT base contracts.
  • NFT.Storage, a library to connect to the NFT.Storage API.
  • Dotenv, a library to handle environment files for configuration (e.g., injecting private keys into the script).

Use the following command to install all dependencies at once:

npminstall hardhat @openzeppelin/contracts dotenv @nomiclabs/hardhat-ethers

Hardhat needs to be initialized in the current folder.
