How to do NFT and maybe why you don't want to do NFT

Exemple : Alex Castro

NFTs have been a cultural phenomenon throughout 2021, and the elite have taken over the region, constantly making headlines for fraud, deception and fighting. However, some developers have made millions of dollars from NFTs, so it's understandable why they try NFTs on their own or play around with their technology to get a good feel for it. .

We'll discuss how to create an NFT using two of the most popular retailers, but before that let's go over some of the key features of what an NFT is and the decisions you'll need to make before you decide to sell your NFT. . (Soon you can skip to step 3 and start browsing the real tokens created.)

Step 1: Know what NFT is

Look, I haven't decided if you come here and don't know what NFT is. Your friend may have said, "Hey, I need to sell my cat photos to NFT". However, it's best to have some understanding of what you're doing before going through the build-and-sell process.

Related NFTs, Explained

An NFT or Unforgeable Token is a digital token stored on a blockchain. Unlike cryptocurrencies where all tokens are the same (no reason to prefer one more bitcoin), all NFTs are unique and can be sold as a way to prove ownership of a portion of digital data.

NFT artwork is almost rarely stored on the blockchain.

In almost all cases, the data is not stored on the blockchain itself. Instead, the link to the file is stored with a symbol, which is proof of the membership link indicates. There is also a rule that you cannot have more than one NFT in the same file. You can have an NFT version like a business card. For example, NFTs can be rare because there are only 10 copies, and they can be because thousands of identical NFTs are "written" or written on a blockchain. Also, I can't stop someone from taking the data they use for NFTs and using it to create their own NFTs.

You can sell digital files in NFT format, but if you want to use the store's easy-to-publish media tools, you'll be limited to supported formats. As we will come to in the future, the original NFT must be an image, video or audio clip. If you don't yet know what you want to sell with NFTs, this type of restriction can help reduce your potential. as is ...

Step 2: Make sure you really want to sell your NFTs.

Everyone loves doing NFT, so if you have a vague idea that you want to do NFT, here are some decisions to make. The first major problem is that of exchange rates. The platform we're going to cover today lets you create NFTs for free, but selling them might be a different story.

Most NFTs are sold on the Ethereum blockchain (we'll talk about what's not on the Ethereum blockchain in the next section), and all transactions on the Ethereum blockchain will need to be paid for based on miner fees. These prices are called "gas" and the amount of gas that needs to be traded (and therefore the cost of trading) can vary. Almost everything you do on the blockchain, from advertising NFTs to delivering them to others, to competing, is fuel efficient (although there are ways to create NFTs, which we'll talk about later late). .

You can invest a lot of money in your business before selling your NFTs.

It should also be noted that fuel payments do not guarantee that the conversion will be 100% complete. You could pay more to give you more, but that's not true. To put it bluntly, most deals will close. However, if something happens and the business doesn't work, you won't get the fuel you paid for.

Then there are environmental issues with NFT. Most of the popular, easy-to-use NFT products run on the Ethereum blockchain, which uses strong "proof of functionality" capabilities. Although there is controversy over whether commercial NFTs alone will affect overall blockchain performance, when NFTs were developed by Ethereum, they would use a large carbon system.

Some blockchains use other technologies that don't consume a lot of power, and Ethereum plans to move to a more cost-effective proof-of-stake at some point in the future. However, this is not yet true, which is one of the reasons people get angry when others decide to sell their NFTs.

Step 3: Choose the platform on which to sell your NFTs

There are many platforms where you can sell NFTs on different blockchains, so it's almost impossible to say which guide is right for you, let alone which guide covers them. We cover the two most popular sites in this guide, but if that platform isn't the job you want, you know there are other options, such as AtomicHub using Wax blockchain or Solsea powered by Solana.

Here our guide will show you how to do things one way. The NFT industry also has deep rabbits that this guide does not cover (such as the sale of NFTs published by Rarible to OpenSea, the programmatic development of content products such as Bored Apes). Please note that this is not an aggregation of NFT sales.

Thanks to the "lazy coins" linked to OpenSea and Rarible, you can create NFTs on Ethereum for free. Lazy Coinage allows you to create NFTs and sell them without using them on the blockchain, avoiding costs. When someone actually buys it, the cost of writing NFT for the blockchain is associated with the transition to the client. This can save you from having to shell out $10-$30 (or more!) to get an NFT that no one else will buy.

When it comes to advertising NFTs, most options have some form of marketing.

There can be deception. Signing up for your first Ethereum NFT sale on OpenSea requires a new account, which can be an expensive affair (we see prices between $300 and $400 in testing). This is a one-time fee, and once paid, you can make your NFT lazy without paying a fee.

With Rarible, you don't have to pay anything for testing. However, if you try to remove the NFTs from your eyes, you will be charged a fee (they cost around $20-30). Rarible and OpenSea both receive a 2.5% commission on the sale price. If you sell your NFT for 0.025 ETH, you will get 0.024375 ETH for real.

However, there are other options besides the Ethereum blockchain. Rarible lets you sell NFTs using the Flow blockchain (the same blockchain used by NBA Top Shot) when you sign up for the Blocto wallet, and OpenSea lets you sell using the Polygon blockchain. Both options are priced lower than paying with the Ethereum blockchain, so I'll show you how to use them.

As you can guess, if there is no downside or downside to low cost/free blockchains, everyone will use them. If you choose to use Flow with Rarible at the time of this writing, you are limited to one version of NFT (one) and cannot be sold at a competitive price. Also, when using non-Ethereum blockchains such as Flow or Polygon, people cannot use Ethereum to buy NFTs (at least without going beyond the cost of induction). Both platforms allow buyers to add money to their wallet to complete their purchase, but require a full exchange or purchase of other cryptocurrencies to earn NFTs, which the author will reveal .

(Note: Polygon allows you to use Ethereum, but this is the latest Ethereum version of Polygon. You can upgrade Ethereum directly from the main blockchain to Polygon, but it will cost less).

Should I use a corporate website to create an NFT?

Not technically. You can create your own smart contracts, submit them to the blockchain of your choice, and use them to create your own tokens. But it's a plunge into the abyss, and it might not be the path you want to take unless you're a very technical person. Most people will want to use one of the platforms described above.

Step 4: Create your own wallet

Wallet is an application that you use to store cryptocurrencies and finally NFTs that you donate or buy. Coinbase has more detailed instructions on how wallets work and the different options, but if you're just starting out, it's worth keeping an eye out. In other words, use a wallet compatible with the blockchain you are using.

The MetaMask wallet is one of the most widely supported wallets for Ethereum-based applications such as OpenSea, Foundation, etc. It is available as a Chrome / Firefox extension or an iOS / Android application. Coinbase also has its own wallet which can be used as an extension or app, supported on multiple platforms. If you plan to have more exposure to cryptocurrencies, you might want to consider a wallet from Coinbase that supports non-Ethereum-based blockchains like Bitcoin.

The process in place for MetaMask and Coinbase wallets is similar. Once you've configured the browser extension or app, click or tap the "Create New Bag" button. Coinbase asks for the username and both ask for the password. Passwords should be secure (we recommend creating and storing them with a password manager).

Keep the promise as safe as possible. Don't steal it and don't lose sight of it. Do not advertise on the Internet, even if it is a lesser known version.

Finally, MetaMask and Coinbase provide terms called "phrases", which are 12 random words. If you need to uninstall the app or reset your wallet on a new device, it's important not to lose it because you can recover your account. Your best bet is to print and store somewhere secure, such as a physical security or admin password (or both). MetaMask asks if you want to repeat this phrase and Coinbase Wallet asks if you want to store encrypted notes in the cloud using app settings. If you configure Coinbase as an extension or choose to restore it manually instead of storing it in the cloud, the same is true with MetaMask which requires you to re-enter the syntax.

If you can't remember your password and/or password, you're out of luck with MetaMask and Coinbase Wallet. No company will do anything for you. This means that you will lose access to the account you have set up with any cryptocurrencies or NFTs stored in this wallet. So, keep your passwords and passwords safe.

Finally, you can access the wallet you didn't put!

Step 5: Attach your wallet

After setting up your wallet, you will want to connect it to the NFT industry you want to use. OpenSea and Rarible make this easy. Click the Create button in the top left and you will be prompted to link your wallet. You will then see a list of similar wallets, select a wallet and you will be prompted for the login process.

Connecting your account to MetaMask is easy if you have an additional browser installed.

If you have installed Metamask or the link to Coinbase, a popup will appear asking if you want to link your wallet with a few button clicks. The Coinbase Wallet app also lets you connect transactions using a QR code scanner (to the right of your balance in your personal wallet).

Future Warning: If you see a request to attach to your wallet, be aware that crooks will attempt to access your wallet or NFTs. As long as you're in a safe place, usually no problem (at least if you're not skeptical - be sure to check the exchange to make sure it's legit). However, if you don't know the website request link for your wallet, you should think twice before accepting it.

Step 6. NFT Generation

Linking your wallet will take you to the page you used to create your NFT (if you haven't arrived here yet, you can access this page by clicking the Create button on the right side of both platforms).

Before we start creating NFTs, let's talk about writing. Both platforms support authoring, which is pretty much the same. If you wish to create the NFT series, you can do so in writing. For Rarible, you can create scripts directly from the NFT creation screen, and the NFT you create will be added to this tutorial. In OpenSea, you must go to your profile picture in the top right and then to My subjects > Create a list.

We won't include the material in this guide, but if you don't specify the creation method, OpenSea will automatically place the NFTs it creates in the anonymous script (you can modify the script to follow or move the NFTs to another domain). Rarible allows you to sell your NFTs as Rarible Singles for free.

Now let's start working on the NFT.

Register NFTs on Opensea

Click the Create button to access the page where you can create a new project. To get started, click the box with the image icon to send your sale file with NFT (remember the file size and format limit above the option).

After adding the file, give it a name or title. You can also use external links to add a URL to your website or Twitter account, and you can use descriptions to better understand what NFT is for consumers.

Some file types, such as movies or music, require a second “preview” image.

Once you have configured a collection, in this field you can select the collection for your NFT and add items, levels or stats that can be used as default metadata. For example, if you are selling NFT that can be used as a video game character, complete the form here. If you are selling an image, you can use the panel to add information such as average, year, etc. However, since all of these fields are optional, many may ignore them.

OpenSea also allows you to add textual content which is not open to NFT buyers/owners. You can use this toggle to include things like a private meeting invite, a ransom number to an external party, or a thank you note for a purchase. If your NFT is an important NSFW, you can use clear content and sensitive toggles.

Find out where the blockchain gives you coins. You cannot change it later and it can have a big impact on the costs you pay.

Below toggle and response is a drop-down card used to select the blockchain (Ethereum chain or Polygon chain) advertised by NFT. You can read more about the pros and cons of each blockchain in Step 3, but in our case we chose Polygon, which currently doesn't charge a fee. If you are printing to Polygon, you can choose to print multiple copies of NFTs.

After selecting a blockchain, you will want to double check everything. OpenSea allows you to update metadata later unless you put it up for sale, but it's a good idea to make sure everything is correct before doing anything blockchain-related. Afterwards, you cannot modify the blockchain that NFT opened.

When you are ready, you can click on the Create button. There may be some latency when downloading, depending on the option you choose and the type of file you sell with NFT. Once complete, you will see a screen indicating that NFT has been created.

Our NFT is on OpenSea, but not on the blockchain. It won't happen until someone buys it.

However, NFTs are not yet sold on OpenSea. To do this, you must click on the happy screen to access the NFT page (click on your profile picture, click on the Create tab and select the NFT entry). NFT pages have eyebrows.

This NFT was developed but not for sale. Click on the Sales button to register.

For NFTs set in Ethereum or Polygon, you can choose to create a fixed price list, while in Ethereum you can choose to create a time frame. For a regular price list, enter the price at which you want to sell the item (listed in Ethereum, but estimate the amount shown below) and choose the duration of the list.

As of this writing, Polygon's OpenSea implementation is only driving sales.

NFTs are available for purchase as soon as they are listed, so you can use the "More options" menu to make them available to specific customers.

Click the "Publish List" button to place your NFT on the sales list. You need to use a browser extension or app to register with your wallet or register for a company. In Polygon, trading is free and you will get a screenshot showing the items listed.

A sample login request in the Coinbase Wallet app.

If this is your first Ethereum NFT, you will need to do a one-time authorization to "start" your wallet as shown above. To do this, you need to have Ethereum in your wallet.

The money from this exchange is only for fuel costs, not OpenSea costs, so the price depends on the current Ethereum fuel cost. I've seen prices between $240 and $450 in my tests, so if the price is high, you'll have to wait for the price to drop. You can view exchange rates using facilities such as Ethereum Gas Station.

Signing up for Ethereum with OpenSea can be expensive.

Once all changes have been approved and signed, the NFT will go on sale on OpenSea.

Print NFTs in Rare

Rarible has a choice from the start.

The first question Rarible asks is whether to create a single NFT or multiple NFTs. An NFT that can be purchased by many people. The screen, you will see a similar screen (if you want to create more than one, you can use Ethereum only, you must specify the price you want to sell). However, in this example, we have chosen Single.

Selecting an item in Rarible will take you to the NFT build interface. The first thing to do is to use the "Select Files" button to send the digital files you want to sell with NFT. Finally, it will be in the Interplanetary File System (aka IPFS), a way to store information so that NFTs don't disappear on the internet if the company decides to shut down.

Like OpenSea, Rarible may require you to resize images in certain media formats (such as video or music). As long as NFTs appear on your site, you can think of them as video thumbnails or album art. .

Rarible has many options on how to sell NFTs.

Next, you set up your put options. If you don't want to sell your NFTs yet, you can deactivate the "Go to Market", which is by default. If you want to sell your NFT, you have several options.

A "fixed price" is equivalent to setting up a retail store. You have set a price for NFT, and if someone wants to pay that price, they can buy it right away.

"Open Auctions" allows people to submit NFT purchases, which they can accept or reject.

"Auction period" is a contest. You can set the minimum price and select the start time and match time.

This example lists NFTs with constant values ​​that can be entered in this field. You can also select the results you want (but people can tell you in other results). When pricing, keep in mind that when NFTs are sold, Rarible charges a 2.5% discount.

After selecting your sales strategy and content, you can choose to add potential content to your potential customers. It could be an invitation to a private dispute, a number to exchange something with an outside source, or a thank you note for a purchase.

The next two options let you select your composite material (using Rarible singles for example) and the free option lets you choose whether or not to use the existing Rarible timeline. If you close this project and use the Ethereum blockchain, you will have to pay fuel to exit NFTs at the end of the process. Up to $120 in testing.

Names and descriptions are important to stand out. Most people will want to enable the free coins option.

Then write the name or title on the NFT and provide a description if needed. Finally, you can choose your royalty rate. This will change how much money will be returned for each sale in the future. For example, if someone buys NFT for 0.2 ETH and then sells it for 1 ETH in the future, you may get a portion of that sale. By default, it is 10% (0.1 ETH in this case).

The last option will help you create an NFT with higher resolution which allows you to add objects to the NFT (optional, but can be used if you want to create symbols with different materials) and more descriptions. Easy to understand.

Check that everything is what you want, as it may be expensive or irreplaceable later. Then, when you are sure that NFT is OK, click on the "Create project" button.

The wallet (MetaMask in this case) will ask you to sign up for certain trades.

This will start doing a lot of things that will need to trade with your wallet. If you're using a browser extension, you should see a pop-up when Rarible asks for your signature (if not, you can click the extension's icon in your browser and ask for something). If you use the app, you must open the app on your phone to view the app.

NFT has been created!

After allowing a few wallets to request and waiting for a few moments, you will receive a message that the NFT has been created. You can see it by clicking the "View NFT" button, and go to your profile picture on the right side and click "My Profile" to see the product list.

If all goes well, your NFT will now be listed for sale on Rarible, OpenSea, or both. But as the seller told me it won't go far for you. As you can see, the process is difficult, but the hot environment surrounding NFTs has led to many people trying to develop NFTs. If you want your sales job, you need to find a way to cut through the noise that makes your image look good (and maybe a little commercially funky), in funky marketing. But I leave that work to you.

PS: If you have an NFT section in your wallet, don't worry. NFTs created with this guide are not available here. Your wallet reads things from the blockchain to know what it's supposed to say, and the lazy NFT doesn't write to the blockchain until someone buys it.
