A tutorial of only 5 steps to create an NFT (non-fungible token) from two different platforms: Rarible and OpenSea.
Twitter CEO Jack Dorsey is auctioning off his first tweet in NFT format and has already received bids exceeding US$2 million. He’s not the only one: NFTs seem to be everywhere.
Rock band Kings of Leon will release their new album in collectible token format. The NFT of a pixelated avatar sells for the price of an apartment in Manhattan. The NBA trades digital cards for sports purposes. Linsay Lohan posts her own NFT on Twitter. Even Taco Bell has decided to start marketing GIF of tacos in NFT format.
In the midst of the growing boom for NFT (non-fungible tokens), and with so many celebrities participating in this curious trend, we do not want to be left out. In this opportunity, DiarioBitcoin presents a tutorial so that you can also make your own NFT or digital collectible.
Photography, art, music: NFTs are unique digital assets, in many cases scarce and expensive, that can represent any digital object. They can also be backed by real-world objects or assets. A painting, a building, a sporting item, an autograph, a game, can all be coined as NFT. The mind is the limit.
We can also think of NTFs as certificates of authenticity backed by Blockchain technology. NFT collections are traded on online marketplaces, think platforms like eBay but where digital items are bought, auctioned and sold. Some of the best known are: OpenSea, NiftyGateway, Sorare, SuperRare, Mintbase, Rarible.
- What are NFTs and why are they causing such a stir in the crypto market?
Things You Should Know Before
As with cryptocurrencies, being digital tokens, NFTs are stored in crypto wallets. So, before starting this tutorial you should keep in mind that you will need a wallet, preferably one with support for Ethereum and that can easily connect to the online NFT markets. For this guide we will use the Metamask wallet.
Before moving forward, you should also keep in mind that NFTs are tokens on a Blockchain, so creating one involves – in most cases – an expense. This is because all transactions on Blockchain imply a cost for that network. Most of the NFT market is currently built on top of the Ethereum Blockchain, where that network fee for turning your art into a token is called Gas.
That said, you will need to have a background in ether to effectively create an NFT. The amount needed will vary according to the network fees at the time of making the transaction, but possibly with a figure of USD $100 in ETH you will be able to create your first collectible token. We know, it’s not economical.Where can I sell NFTs?
There are many online platforms you can use to make and sell an NFT. Some of the most popular NFT auction platforms are OpenSea, Rarible (pictured above), SuperRare, Nifty Gateway, Foundation, VIV3, BakerySwap, Axie Marketplace, and NFT ShowRoom.
Some of these sites will allow you to create your own listing by uploading a copyrighted file or image. Others allow anyone to enter and buy, sell or trade NFTs created by other people.
The most important thing before buying an NFT is to find out if the artist or creator owns the copyright. If they do not have permission from the copyright holder to create and sell an NFT based on their work, the buyer could be on shaky legal ground.
If you want to sell your art or collectibles on a platform that is not as competitive as others in the market, consider creating your own NFT website using a tool like Mintable.io.Tutorial: How to create an NFT?
We will use two platforms that allow us to create NFT: OpenSea and Rarible, in this way we will also observe the differences between each one. The first is completely free, although the fees for the transaction still apply, while the second charges a small fee for putting the NFT on the market.
We warn that this activity is not without risk. Like any operation with digital currencies, this requires taking some precautionary measures around the security of the digital assets that are going to be traded, both in the method of storage and exchange. Step 1: Set up the wallet
After entering the platform, the first step before you can create an NFT is to connect the wallet. This process is quite simple and very similar in the case of both platforms. One of the favorable features of both is that they do not require registering an account, the user can interact directly by linking their wallet. In Rarible:
The main page of Rarible.com shows two buttons in the upper corner: ‘Create’ and ‘Connect Wallet’. Both options lead to the same place, since the platform will direct the user to connect the wallet based on being able to create a new token or bid for an existing one. After pressing one or the other button, several options appear to link the wallet.
Possibly the simplest option is That of Metamask. If we have that wallet installed and choose that option, a Metamask pop-up window immediately opens on the side of the screen. From there, we select ‘Next’ to integrate our wallet with the platform. After concluding this process, which includes accepting Rarible’s terms and conditions, we can start creating an NFT.
Similar to Rarible, when opening the page OpenSea.io, in the upper corner we see several options, including ‘Create’, to create a new collection or NFT. When clicking, immediately the platform takes us a page with several options to connect the wallet. If the user has Downloaded Metamask in their browser, it will appear automatically to integrate it with the platform.
On the right side of the screen, a Metamask pop-up window requesting the connection with the platform will be displayed; here we click ‘Next’ and ‘Connect’ to conclude the process.
OpenSea asks the user to issue a signature with the address of the wallet, for this we only click ‘Sign’ in the Metamask application. In this way, the user is automatically registering on the platform without the need to generate an account or password.
Step 2: Create your digital art
This is perhaps the most fun part of the project. As we indicated above, you can coin basically any digital object as an NFT. It can be a song, a photo, a drawing, let your imagination run wild. But, yes, make sure that the file you are going to use is not copyrighted or owned by someone else.
In Rarible. Users can upload various file types: PNG, GIF, WEBP, MP4 or MP3, with a maximum weight of 30 MB.
In OpenSea. Compared to Rarible, it seems to have a greater variety of file formats. JPG, PNG, GIF, SVG, MP4, WEBM, MP3, WAV, OGG, GLB, GLTF can be loaded, with a maximum size of 100 MB.
That is, the token can be based on a digital file in any of these formats. Step 3: Coin your first NFT
Once we have chosen or created the file that we are going to convert to NFT, we are ready for the third step. In the case of both platforms, the NFT to be minted must be accompanied by an image, a name, a description and another series of fields that will identify the collection. In Rarible:
After selecting ‘Create’, Rarible offers two possibilities for coining an NFT collection: ‘Single’ and ‘Multiple’. The first allows you to create a unique token (ERC721), while the second, a handful of the token (ERC1155), depending on the amount the user chooses to launch into circulation.
Once we have chosen whether we will create an NFT or multiple of them, we move on to the creation part of it. The platform thus deploys a series of items that we will fill out to create the collectible, including loading the file that we want to convert into NFT.
We will also be able to decide whether to place it immediately for sale on the market after it is created or not, as well as the sale price. In this last aspect, Rarible allows the creator to choose a sale price or let the interested parties set it by bidding for the token.
