How to sell NFT?

Various platforms but I recommend Opensea. 


STEP1. Open the top page of OpenSea

First, open the OpenSea top page.


STEP2. Connect with MetaMask

Click on the doll icon in the upper right corner of the screen.

Select "MetaMask".

(If you don't have a MetaMask, I recommend you make MetaMask Account)

Enter your password and click the "Unlock" button.

Click the "Next" button.

Your profile page will open.

STEP3. Create a collection in OpenSea

Click on the icon in the upper right corner of the screen and select "My Collections".




When My Collections opens, click the "Create a collection" button.



STEP4. Enter collection information

Let's enter the collection information.


Let's start with images.


Logo image: Icon representing the collection

Featured image: An eye-catching image that represents the collection (used in the introduction page of OpenSea, etc.)

Banner image: Header image of the collection

Make sure to create a good image for the collection.


Next, enter a description of the collection.



Name: Name of the collection

URL: URL of the collection

Description: Introduction to the collection

You cannot use the name and URL of an existing collection.

The introduction of the collection should be a good introduction to the concept of the collection.


Next is the category.


If you are selling many similar images, "Collectibles" is recommended.


Put enter the URL for each.

This is always checked, so be sure to make sure that your media are also well prepared.



OpenSea allows you to receive a portion of the fee as royalties when your work is resold.




***If you don't set this up, you won't get paid when your work is resold, so be sure to do so!


In the "Percentage fee" field, enter the percentage of the royalty you want to receive.

After entering the values, the "Your payout wallet address" field will appear, so enter the address of your MetaMask.

Next, select the blockchain you want to use.



If you want to sell using the Ethereum blockchain, select "Ethereum" under Blockchain.

(You need Gas Fee when you sell NFT but totally recommended Ethereum because
NFT collectors doesn't collect other crypto)

Choose ETH if you want to sell it for a fixed price, or WETH if you want to sell it at auction!

Finally, choose how you want your work to be displayed.



Please turn on "Explicit & sensitive content" only if your work is Explicit & sensitive.

When you are done, click the "Create" button.


STEP5. Upload the work you want to make into NFT art!

Click "Create" in the upper right corner of the screen.



Enter information about your artwork.


Image, Video, Audio, or 3D Model: Upload your artwork

Name: Name of the work

External Link: Enter the URL of a web page that introduces the work in detail, if any.

Description: Describe the artwork.


Next, choose which collection you would like to sell your work in.

Click on the down arrow to the right of "Select collection" and select the collection you just created.




Here you can set the characteristics of the work in detail.

Properties: Grouping of the collection

Levels: You can set the status of the collection.

Stats: You can set up statistics.

Unlockable Content: Whether or not the work can be unlocked.

Explicit &Sensitive Content: Whether the work is stimulating or not


Let me explain "Properties" and "Levels".

I recommend that you leave "Stats", "Unlockable Content", and "Explicit &Sensitive Content" at their default settings.


First, "Properties" allows you to group works like this.



You can choose the color, sex, accessories, and so on.

This will allow you to filter the artworks, which will be useful for buyers when selecting artworks.


In the "Levels" section, you can set the status of the work like this.



You can set the contents of the Levels to anything you like, such as Speed, Power, Intelligence, and so on.

You can imagine that you can set up the fighting ability when it is used as a character in a game.


Next, select the blockchain to be used for trading.



Supply: Limited number of pieces to sell

Blockchain: Select the blockchain you want to use to buy and sell.

Freeze metadata: Freeze data or not

Select "Ethereum" if you want to sell using the Ethereum blockchain, and select "Polygon" if you want to sell using the Polygon blockchain.


If you choose "Freeze metadata", the images will be uploaded to OpenSea's servers if you do not set it, or to a decentralized server (IPFS) if you do.

If OpenSea were to disappear, the image data uploaded to the OpenSea server will be lost.

If you want to keep your work permanently If you want to keep your work permanently, you should set "Freeze metadata". However, you will have to pay for the gas!

 If you set "Freeze metadata", your information will be frozen and you will not be able to edit or delete it permanently, so be careful!


Click the "Create" button when you have entered all the information.


STEP6. Put a price on your NFT art!

Next, let's put a price on your work.



Click the "Sell" button in the upper right corner of the screen.


Select "Fiexed Price" as the Type.

If you want to sell at auction, select "Timed Auction".


Enter the price you want to sell for in the Price field.


In Duration, you can choose the selling period.


When you have entered all the information, click the "Complete listing" button.


STEP7. Let's have NFT issued!

To sell NFT art, you must first initialize your wallet.


You will need to pay a fee (it's called gas) to initialize your wallet, which will allow you to use the Open Sea service.

MetaMask will display the required gas fee, so check the details and click the "Confirm" button.


You only have to pay for gas the first time! The rest you can sell for free!


After a few minutes, you will see this message in the lower right corner of the screen.


Next, you will sign the form to list your property.


Move the scroll bar on the right side of the screen down, making sure to check the message displayed in the MetaMask.


Click the "Sign" button when you are satisfied with the content.


Your NFT art is now complete!
