How to create (and sell) an NFT on the blockchain for free?

Do you want to create an NFT to make a fortune on the blockchain, but you don’t know how to go about it? Follow the leader.

Increasingly popular, NFTs are establishing themselves both as collector’s items and as veritable digital works of art that are snapped up at exorbitant prices on the blockchain. However, creating a non-fungible token is not very complicated.. The exercise is even free, and only takes a few minutes. We explain how to do it.

What is an NFT?

Before hoping to become an ether billionaire, let’s start by going over the basics. An NFT (for Not fungible token), is a virtual certificate linked to a blockchain, which makes it possible to authenticate a digital work. Concretely, the file is similar to a bitcoin or any other cryptocurrencysince it can be sold, stored, or traded securely on a crypto marketplace.

The only fundamental difference with a non-fiat currency: the NFT is not interchangeable in its value. It would be like comparing a €50 note and a work of art: if you lend someone a note, it doesn’t matter if they return the same, as long as the value corresponds to that lent. In the case of a work, we expect on the contrary to recover the same, without exchange or equivalence.

From the first tweet in history, to pixel art, to the (living) arm of an athlete, to virtual items, it’s possible to sell just about anything under the form of an NFT… provided of course that own the copyright to the work in question. Then it remains to choose how and where to host your NFT.

How to create and sell your NFT?

Once your work has been created, it is necessary to choose the blockchain on which you want to have your NFT authenticated. Generally, Ethereum is ideal for digital works, but other alternatives exist. If it is not already done, it is then necessary to create a crypto wallet, essential to receive your cryptocurrencies in case of sale, but also to store your NFTs. Again, there are several solutions. If you are a beginner, we advise you to opt for MetaMaskwhich has the advantage of being versatile and easy to learn.

Once your wallet has been created, you need to choose a marketplace. This is where you can create and sell your NFTs. Among the best known, we can obviously mention Opensea, Rarible or Mintable. All present themselves as digital art galleries, where transactions are made in cryptocurrencies. Note only that some platforms require “gas costs” for the creation of a virtual work. Rarible is the only one to offer an option “Free Mining” on Ethereum, in order to leave this step at the expense of the buyer. You can also use other gas-free blockchains, such as Polygon.

As you will have understood, it is therefore possible to create an NFT for free, and in just a few minutes. Once the file has been uploaded and the details of the work entered on the platform, all you have to do is electronically sign the required documents and authorizations. Your NFT exists, it is now accessible directly from your wallet, while waiting to find (or not) a potential buyer.

All that remains is to promote your product to encourage collectors to buy it, which is undoubtedly the most complicated part of the exercise. Also note that even once sold, your NFT can continue to earn you big: with each resale, the original creator receives a commission.
