Want to mint a piece of art, design, audio track, or any other digital asset on the blockchain?
Interested in creating NFTs and being a pioneer of web3 and the internet of value?
In the following tutorial, we will show you step by step how to create your own non-fungible tokens, totally free (no gas or transaction fees).
Investors collect NFTs like any other financial asset. What is sold as NFTs – we can also say “tokenized” – can sometimes make you smile.
We remember the crazy sums reached by some pixelated CryptoKitties.
And when we say “crazy sums”, we mean that these images are sometimes exchanged for the equivalent of several hundred thousand dollars.
What’s fascinating is that NFTs are no longer a novelty, and yet… more and more smart people are managing to use them to generate lots of money.
You could almost say that it’s “so easy even a 12-year-old could do it“.
To hurt your ego, even more, let’s put our money where our mouth is and tell the story of Benyamin Ahmed.
This 12-year-old British boy jumped on the NFT bandwagon a few years ago.
He and his brother have been taking programming classes with his father since the age of 6. Benyamin Ahmed’s first NFT project was a Minecraft-inspired graphic design.
But it was his second attempt, titled “Weird Whales,” that won him over $400,000.
Inspired by other similar adventures, Weird Whales consists of pixelated whale designs generated by an algorithm that makes them more or less unique.
In total, he offers more than 3,350 of these whale drawings on the OpenSea platform.

NFT: What Does it Mean?
NFT stands for Non-Fungible Token. This does not necessarily make things clearer. That’s why we need to detail the notion of “non-fungible“.
For example, bitcoins or €100 bills are fungible. Even if each bill is unique, it will have exactly the same value as another €100 bill.
The first bitcoin mined, no matter which platform it is on or who owns it has the same value as a bitcoin recently mined and stored in another wallet.
Conversely, artwork or concert tickets are non-fungible.
Something that is not fungible cannot be replaced or divided. It is unique.
They are objects of the same nature, but with their own characteristics and utility.
We talk about “tokens” when they are digital units, which are exchanged with the blockchain technology: 3D visuals, objects in a video game, or a piece of land in a fictional universe.
The NFT can thus be defined as follows: it is the digital property title of a non-fungible token.
NFTs can be classified into different categories according to their nature and their utility:
- Collectibles: a collection of digital objects, or a work of art for example;
- Metaverses: virtual worlds;
- Online game tokens;
- Utilities: they provide a service to their owner.
First of all… Create Metamask ( The crypto wallet & gateway to Web3 blockchain apps)
Create your wallet for the web3. Since we’re working on the Ethereum network, we’re going to need a web3 wallet for this.
In this case, you don’t have to choose, in fact, our recommendation is Metamask, because it’s the best and the one everyone uses.
A custodial-free browser wallet that allows you to access all the decentralized applications (DAPP) in the ecosystem.
I made a tutorial on the YouTube channel, so check it out if you need it.
Prepare Your Project
It’s not about tokenizing anything to automatically give it value.
Blockchain technology allows you to create any rare, unique asset with an origin and an owner, as well as on an immutable network.
But from there to having a value in a token, there is a long way to go.
An artist, for example, does not become an artist overnight; it takes preparation, and self-knowledge to be able to develop one’s own style, a certain trajectory, or an audience?
What we mean by this is that before creating an NFT, ask yourself why you want to do it, what will be the use of this token…
give it a structure, a meaning; and don’t give up after a first failure, because success is not sudden.
Create Your NFT Collections on Opensea Without Gas Fee! (in Just 5Mins)
As we’ve already mentioned, there are several options for creating NFTs and minting digital assets on the Ethereum network.
However, OpenSea recently launched its “gas-free” feature to create non-fungible tokens.
Once you’ve connected your wallet to Metamask, to create a collection of NFTs, or mint a piece of work separately, go to the Opensea Official website and click on the “Create” section in the upper menu.
From there, click on “My Collections” or “Submit NFTs“:
The “My Collection” section is your control panel, in other words, your NFTs store back office.
As you can see, we already have 2 collections created: one with OpenSea and the other with Rarible, but visible from the platform.
In your case, it is possible that you do not have any collections created. That’s ok, that’s what we are here for. Just click on the Create button.
Then a pop-up will appear for you to configure the collection data or the series that will group your NFTs.
As indicated here, you will be able to change this information later, so don’t be in a hurry.
Here you have to place the logo or image that represents your collection, the name of the collection, and its description.
This is the counter of your NFT project, so dedicate time and attention to it.
Once you have entered all the data, click Create and your collection is ready.
You should see your public page, which you can edit: header, layout, verify your collection, etc.
Easy, isn’t it? Now, either you continue editing your collection, or you start adding NFTs, non-fungible tokens, that are part of the collection.
As simple as clicking on “Add New Item“.
You will see the page to upload the asset file, which currently allows: JPG, PNG, GIF, SVG, MP4, WEBM, MP3, WAV, OGG, GLB, GLTF, and a maximum file size of 100MB.
In addition, OpenSea allows you to add the NFT name, description, an external link, and the total supply number of that asset.
Currently, by default it only allows you to mint one piece, one copy; to try to maintain the exclusivity of tokenized assets on the platform.
However, if you really want multiple copies of the same asset, contact their Discord team.
And that’s all, your item will appear in the collection and in your wallet.
Zero transaction cost and in less than 5 minutes.
As shown, you can request verification to ensure authorship and start selling your NFTs to the rest of the community.
Other Platforms to mine NFTs
To create NFTs there are multiple platforms, many focused on the creative crypto-art scene.
Some of them, as in the case of Rarible, have their own governance token, so operating with them has its benefits.
Below I leave you a list of platforms to create and my non-fungible tokens on the Ethereum network:
OpenSea does not owe its leadership position to change. With a huge choice of NFTs and a pleasant interface to browse, both on the computer and on mobile, the company gives itself the means of its ambitions.
The tools offered to creators as well as the competitive fees encourage artists to come and enrich the platform’s library.
Buyers will also find their account there, provided they pay attention to the sometimes high transaction fees for NFTs that go through the Ethereum network.
The biggest obstacle to the more massive adoption of the platform is probably the requirement to have a crypto-wallet and to pay in cryptocurrencies.
Being able to pay with a bank card, as is possible with some competitors, would help democratize the NFT world a bit more.
Thefts of NFT by phishing are also detrimental to OpenSea, whose security remains a major issue to reassure (future) users of the platform.
