 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.)

Do You Eat Dog Meat?

Image
  Around early 2022, I watched a video of a big dog being forced by a man to go up to a truck. The man was apparently a dog meat trader in a certain part of China. He was using a sharp tool to grip the dog’s neck, which obviously caused it pain and made it fearful as could be seen from its expression. There were other dogs on the truck. It was a sad sight to behold. There were quite a lot of onlookers around. I was shocked that none of them intervened. I knew it could get them into trouble with the dog meat trader if they were to intervene. But if some of them had stepped forward to help the poor dog, it was very likely to be saved. Surely they could buy it or at least call an animal shelter? How could they be so indifferent to the way the dog meat trader handle it? Dogs aren’t poultry. They are supposed to be pets doted by humans, not killed and eaten as food, isn’t it? Moreover, dogs are said to be very loyal. So how could anyone have the heart to kill and consume them? Okay, I k
