OpenSea supports NFT trading across multiple blockchains. This guide explains how to use our Polygon marketplace to create and sell NFTs without paying any gas fees.

That's right - no gas fees or ETH are needed!

 

Creating a Collection on Polygon

To start creating NFTs for free, click your profile icon and press "My Collections".

 

 

Next, click "Create a collection". 

 

 

Make sure to add your collection logo, description, banner, social media links, and set your royalties. 

You can also select which blockchain to create NFTs on by default. Click on the dropdown menu and select "Polygon".

 

 

Polygon supports Polygon ETH by default, but you can also add Polygon DAI and Polygon USDC (see below). 

 

 

Creating an NFT on Polygon

Now that your collection has been created, you can add an NFT by pressing the blue "Add item" button in the top-right corner.

 

 

You can now create a new NFT item. Upload your file and customize your NFT details!

 

 

Another benefit to Polygon, is that you can now create a "semi-fungible" item for free. By increasing the "Supply" of your NFT, you can increase the number of copies that can be minted. This means your item can be owned by multiple wallets. 

 

 

Once you're done, hit the blue button "Create" to create your NFT. Once your NFT has been created, you'll see a confirmation window (see below).

 

 

Congrats! You've just made your first NFT on Polygon.

 

Selling an NFT on Polygon

Now, let's sell your first NFT on Polygon. Visit your NFT and press "Sell" in the top right corner. 

 

 

You'll be taken to a new pop-up window, where you can set your selling price, currency, and view any potential fees associated with your sale. You can also schedule your sale in advance!

 

 

Once you've confirmed your sale details, press "Complete listing". You'll be asked to complete your listing in another window. 

 

 

Click "Sign", and then your crypto wallet will prompt you to sign the transaction on your end. If you're using MetaMask as your crypto wallet, the signature request will appear like this. 

 

 

Click sign and your authorization will complete shortly after. 

 

 

Once your NFT listing is confirmed, you'll get a confirmation showing "Your NFT is listed!". You'll now be able to copy the item link and share it on social media!

 

 

You can also head back to the item page to see how your newly-listed NFT will appear to potential buyers. Good luck with your sale!
