You’ve probably heard of what NFTs are, and might be wondering how you can make some of your own. Whether you want to showcase your artistic prowess, have your chance at making a fortune, or simply immortalize a meaningful souvenir on the blockchain, I am about to show you how to create (or ‘mint’ in NFT lingo) your NFTs. And good news — it’s not complicated! Just like how you don’t need to know how to bake bread to make a sandwich, creating an NFT can also be simple and hassle-free.

In less than five minutes, you can mint your own NFTs on Krafterspace with nearly zero knowledge of blockchain technology. Krafterspace is an NFT minting platform that runs on top of Klaytn — a fast and reliable public blockchain platform developed by South Korean tech giant Kakao. It has a user-friendly interface for you to mint, showcase, and exchange your NFTs in an easy, breezy way. Plus, Krafterspace lets you mint up to 10 NFTs and 3 collections daily, free of charge!

Here’s the step-by-step guide on how to mint NFTs on Krafterspace.

Minting your NFT

Step 1: Get Kaikas

First and foremost, you need to get Kaikas — a Chrome extension wallet based on the Klaytn network. It will be used to sign in and make signatures for the NFT transactions on Krafterspace. Once you have it installed, you should be able to see it in “Extensions” at the top right of your browser.

Proceed to create your account, store your seed phrase and have your wallet unlocked.

Step 2: Sign up for Krafterspace

If you haven’t signed up for Krafterspace, click “Register” on the front page. You are already connected to Kaikas, so your wallet address is automatically filled out for you. Choose your preferred nickname, enter your email address, give your signature and go through the verification process.

Step 3: Sign in

Now log in to Krafterspace, where you will be prompted to sign in using Kaikas.

Step 4: Create your NFT

Once signed in, you can start creating NFTs. The process is very straightforward thanks to the friendly user interface. Right on the front page, you will see the “Create NFT” button. Just click on it, and you are all set to actually mint your NFT!

First, you’ll need to upload the image or video file of your NFT. Just remember that both images and videos have to be at least 600 pixels in width and height.

You can then set the background color, choose a name for your NFT, and add a description that best showcases your piece.

Step 5: Set Properties, Levels, and Stats

Using properties, levels, and stats, you can give special traits for your NFTs. With Properties, you can set random properties like gender, hair color and so on. It will be displayed as a rectangle. Levels and stats also display properties as a progress bar and as numbers, respectively. This feature will be more useful if you have a generative NFT art project or game items. They will appear under your NFT.

Once you are done filling in your NFT traits, click “Create NFT” to mint your NFT.

That’s it, you’ve just made your first NFT! After you have minted your NFT, you can look at it under the “My NFTs” menu.

Creating a Collection

You can also create your own NFT collection, if you plan to create works of art with a central theme. If you don’t want a collection, the NFTs you create will be displayed under the KRAFTERSPACE collection.

To do this, return to the front page and click on the “Create a Collection” button.

Here’s where you will need to upload a fancy logo and banner that will make your collection stand out, followed by a name and description for your project.

For the contract type, you can choose between KIP-17 and KIP-37. What’s the difference? KIP-17 is just a straight-up NFT: a single, unique piece of art. On the other hand, KIP-37 allows you to mint multiple numbers of an NFT. However, in terms of UI (user interface), there is no difference.

Once you’ve filled in all the necessary details for your collection, click on “Create” to create your Collection.

After your collection is created, it will appear in the dropdown menu under Collection.

Selling your NFTs

Step 1: Connect your Kaikas wallet to OpenSea

The best place to sell your NFT masterpiece is on OpenSea, the world’s biggest NFT marketplace. In order to do so, connect your Kaikas wallet that you minted the NFT with to OpenSea. This is done by clicking on the wallet icon on the top right corner, followed by “Show more options”, then selecting Kaikas.

And voila! There you have it. The mortified_dude piece is now on OpenSea.

Step 2: Put it up for sale

Now if you want to sell your NFT, you have to go through the steps below. It costs a little transaction fee, but hey, it could be a worthwhile investment, right?

Select the NFT you want to sell, and click “Sell”.

Enter the details of the sale, like the price and duration. and then click “Complete listing”.

Then you will be prompted to take some steps that are required to complete your listing. First, unlock selling functionality. It does cost a little transaction fee, but not too much. This only needs to be done once.

So that you may rest assured, look at how much the transaction costs.

And then proceed to unlock currency, which also requires a transaction fee. This also needs to be done just once.

And then one final signature is required.

There you have it — with Krafterspace and OpenSea, anyone can mint and sell NFTs with just a few clicks. Stay tuned for our next article where we are going to take it to the next level: showing you how to code your NFT from scratch!

Greetings to Klaytn and OpenSea users,

We would like to inform the Klaytn and OpenSea communities of an upcoming contract migration scheduled for January 6th 2022.

This contract migration is part of the OpenSea and Klaytn integration maintenance, and is an update to move to a new verified deployment of the 0x exchange contracts on the Klaytn network and its accompanying asset proxy contracts. This suite of contracts facilitates interaction between the Klaytn network and the OpenSea platform.

In addition, we will also be using this opportunity to add support for KIP-37 and royalties distribution for Klaytn based assets on the OpenSea platform (KIP-37 is the Klaytn corollary to the ERC-1155 NFT interface definition).

After the update, two new features will also become available to Klaytn OpenSea users:

  1. Users will be able to list, buy and sell KIP-37 based NFTs.
  2. Auction royalties will be fully supported for both KIP-17 and KIP-37 based NFTs. You can find out more about the OpenSea royalties structure here.

These features will allow Klaytn based users to have a more complete OpenSea experience, giving them the full breadth of what the OpenSea marketplace has to offer.

Who will this affect?

The migration will affect current users of the OpenSea platform who have accounts holding Klaytn based assets (KIP-7 or KIP-17), or accounts that have auctions or bids for auctions which are for Klaytn based assets.

What will happen?

After the migration, the OpenSea orderbook for Klaytn based assets (including auctions and bids for auctions) will be reset. Additionally, any pre-existing approvals will likewise be reset.

Support for Klaytn based asset royalties will be activated and the NFT standard KIP-37 will be available.

What do OpenSea users with Klaytn based assets need to do?

If you had any active auctions for Klaytn based assets

You will need to recreate your auctions as the orderbook will be cleared during the migration process.

If you had any active bids for Klaytn based assets

You will need to place your bids again after the asset owners recreate their auctions post-migration.

Detailed instructions on how to auction or bid on Klaytn based assets can be found here.

One-time approval of the new contracts

When you make your first buy or sell action after the migration, you will be required to approve the integration contracts, even if you had previously approved them before the migration.

This approval will only need to be done once per account per token, and can be completed by following the steps below.

Contract approval steps

KIP-17 NFT approval

To start, head to a KIP-17 NFT item that you own and press the blue “Sell” button on the item page.

Set your desired listing price, eg. 10 WKLAY, then press “Complete Listing” at the bottom.

You’ll then be prompted to complete your listing with two signatures. The first of these signatures is to approve NFT selling for this specific collection. Click “Confirm” in your wallet to proceed.

After this the additional second wallet signature will appear, this signature authorizes the listing of your item, after which your item will be listed.

Secondary listings from the same NFT collection will only require a single listing authorization signature.

KIP-37 NFT approval

KIP-37 NFT approval is similar to KIP-17 NFT approval, but requires a third additional signature the first time you list a KIP-37 item.

To start, navigate to your KIP-37 NFT item page, click “Sell” and set a price.

As seen in the above image, since KIP-37 tokens are newly supported, there will be an additional token unlock signature request between the collection selling approval signature and before the listing signature for a total of three signatures.

Click “Confirm” or “Sign” each time to proceed with listing your KIP-37 NFT.

Similar to the KIP-17 case, the token unlock and collection selling approval signatures are not needed for additionally listed items from the same collection, only a single listing authorization signature.

We are very excited to bring these new features to the Klaytn and OpenSea communities. We would like to thank our community members for their support, and ask everyone to excuse the interruption during this migration process as we work towards providing a better Klaytn/OpenSea experience.

If you have any questions regarding the migration, please join the Klaytn Official Discord or contact OpenSea support here. To read the post and approval instructions in Korean, please click here.
