Creating NFTs on OpenSea Polygon Blockchain: Step-by-Step Guide



Introduction

Interested in creating your own NFTs but unsure where to start? This step-by-step guide will walk you through setting up MetaMask, connecting it to OpenSea and creating your first NFT collection on the Polygon blockchain. 

Whether you're new to crypto or looking to explore NFTs, these easy-to-follow instructions will get you ready to launch your digital assets with confidence.

Installation of MetaMask

First off, you've to install the MetaMask as an extension on one of the following web browsers:

1. Google Chrome

2. FireFox

3. Brave

Here's how to do it:

1st Step

Click on the 3 lines as shown in the image below:


2nd Step

Select "Add-ons and Themes" in the drop-down menu as shown below:

3rd Step

In the search bar as shown below, search for the cryptocurrency (crypto) wallet you want. You can choose any wallet. 

4th Step

Once you've your MetaMask extension or any other extension, you'll have to create an account for the wallet of your choice. For convenience, I'm going to be using MetaMask in this step-by-step guide henceforth.

(Please note that I won't be teaching you how to create an account here.)

5th Step

Go to OpenSea website (opensea.io). Then click on the profile image, as shown below:

6th Step

Next, connect it with the crypto wallet of your choice.

7th Step

Now I'm assuming that you've already created an account for MetaMask or any other crypto wallet. So the next step is that you'll have to enter your password.

How to Create an NFT Collection

8th Step


You're now ready to create an NFT. You've the option of creating a single NFT or a collection. If you choose to create a single NFT, then click on "1". If you want to create a collection, then click on "2".

If you choose to create a single NFT, it'll be categorised automatically under a collection, as shown below:

9th Step

Here, I'm going to show you how to create a collection. First, you need to click on "Create a collection", as shown below:


10th Step

Next, click on one of the wallets. Since I’m using MetaMask, so I’ll click on the first one below.

11th Step

Next, you’ll have to sign in to your wallet. Simply click on "Sign", as shown below:

 

12th Step

After you’ve signed in, you'll have to upload a logo image, a featured image and a banner image:


(Note that I'm just showing you where to upload your logo image. Featured image comes right after the logo image followed by the banner image.)

13th Step

You've to select a category next. As my NFTs are artworks, hence I'm listing them under "Art".


14th Step

Here you can decide the percentage fee you'd like to collect when a user resells your NFT.


15th Step

Next you've to indicate your payout wallet address:

Here's how to find your payout wallet address:

At the place where the arrow points, there are alphabets & numbers that show your address. Simply click on it. Then do a right-click to copy and paste it after that.

16th Step

Now you've to select the blockchain. As this guide is about creating NFTs on the Polygon blockchain, hence you'll have to click on the drop-down menu as shown below:


Then click on "Polygon".

17th Step

Now you’ve to click on “Edit” as shown below if you intend to freeze the metadata for your NFT on OpenSea. Why freeze? You might ask. Well, you’ll have to freeze it if you want your NFT to be permanently stored and never be lost. And moreover,  doing so protects your metadata from being edited by someone else.

 

Important Point to Note

Once you freeze the metadata, you can no longer make any changes. So before you proceed to freeze, make sure that everything is according to what you want.

18th Step

Scroll all the way down until you see “Freeze metadata”. Then click at the place where the arrow points:

19th Step

Next, click on “Freeze” as shown below:

20th Step

You'll come to this page shown below. Just tick and then click "Confirm".

21st Step

Once you’ve clicked on “Confirm”, you’ll be asked to sign. Just click on “Sign”.

 

22nd Step

I’d advise you to take down the transaction hash. Why? Because in the event that you want to contact OpenSea support team, you’ll need to indicate the transaction hash.

After you've clicked on "Sign" as shown above, you'll come to the following page. Just click as shown below:


Once you click on it, you’ll come to the page shown below. You may want to record the transaction hash somewhere. Alternatively, you could check out an article on OpenSea that pertains to this.

 

(Note that this opens up on another page.)

Last Word - Log Out

I'll show you how to log out during the next blog post. I think it's important that you log out properly to safeguard your accounts.

Conclusion 

Creating NFTs and managing digital assets may feel complex at first, but following these detailed steps simplifies the process. 

Once you've created your collection on OpenSea and configured your settings, you're ready to share your work with the world!

Despite the stigma, it’s crucial to have open conversations about it, especially because it often stems from mental health struggles that require understanding and compassion. How Prevalent is Suicide Globally? With over 700,000 people dying by suicide every year globally, this equates to one life lost every 40 seconds. ( https://www.who.int/health-topics/suicide#tab=tab_1 ) This number may be higher due to under-reporting caused by stigma surrounding suicide in many cultures.  ( https://en.m.wikipedia.org/wiki/List_of_countries_by_suicide_rate )  Suicide is one of the leading causes of death globally.( https://www.who.int/news/item/17-06-2021-one-in-100-deaths-is-by-suicide ) The global suicide rate is about 9 per 100,000 people, but it va...

5 Ways to Overcome Your Irrational Fears

What is Fear? Fear is an emotional state that's evoked by threat of danger. And it's usually accompanied by physiological changes such as increased heart rate, as well as behavioural changes such as avoidance of fear-producing objects or situations. A certain amount of fear is necessary for our own good. That's healthy fear, as I'd like to call it. However, when it becomes irrational, it's no longer healthy and it could do us harm instead.  What is Irrational Fear?   Irrational fear is fear that isn't  situationally appropriate. In other words, it's out of proportion to the actual threat. And it can be a symptom of some mental health conditions , such as PTSD and panic disorder. According to the author of Conquering Fear, an overdose of fear can keep us perpetually tense, emotionally closed and paralysed to the point of inaction.   (Pg 24)  Do we want any of these? Obviously no, right? Therefore, it's important that we recognise signs of fear s...
