How to make your own NFT and sell it for free

How to make your own NFT and sell it for free.

If you are interested in cryptocurrency and blockchain technology and want to make money from it, you have probably heard of NFTs. They allow you to turn artworks and digital works into NFT tokens, and then sell the tokens on the NFT marketplace.

In this step by step guide, we will show you how to create your own NFT image and how to sell it online for the first time.

What’s an NFT?

NFTs or non-fungible tokens are pieces of unique data stored on the blockchain. An NFT can be a video, image, GIF, or any form of digital art. NFTs represent digital ownership of art, music, and many other types of files.

The “non-fungible” part is what distinguishes NFTs from fungible assets such as gold, silver, fiat money, and cryptocurrencies. Their fungibility means that, for example, you can exchange $100 for any other $100, or that one ounce of gold has the same value as any other ounce of gold.

All NFTs as digital assets are unique. You cannot trade one NFT for another NFT, making them non-fungible.

It’s important to remember that an NFT is not an object, but a string of characters that you can use as proof of ownership. NFT can also publicly verify that your digital file is genuine and not a copy.

How Do NFTs Work?

NFTs require the creation of digital tokens through a technique called cryptography. In the crypto world, this process of creating a token is called minting. As a rule, to create an NFT, you need to pay for the creation of smart contracts.

Smart contracts are pieces of software code that allow the blockchain to store information in a secure and transparent way. Ultimately, these codes govern the ownership and transferability of the NFT.

How Much Does Selling NFTs Cost?

When you sell NFTs, you should also expect to spend some money on it. Most NFTs rely on the Ethereum blockchain to validate transactions, and even creating an NFT can cost you money.

The exact amount of money you will have to pay to sell NFTs depends on Ethereum’s “gas fee”, which varies by time of day and from one platform to another. While you can’t avoid gas bills, you can keep them to a minimum by waiting for gas prices to drop. You can use websites like Etherscan to find out the current price of Ethereum gas. Another reason for not having a fixed price for creating and selling your NFT is that the NFT gas fee also depends on the size of your digital asset and the complexity of the transaction.


On some NFT platforms, buyers pay a gas fee to validate a transaction on the blockchain through their digital wallet. On other platforms, you, as a merchant, must pay a gas fee in order to mint and sell NFTs. Although there are no exact figures on how much it costs to mint and sell NFTs, here are the average estimates:

$70 to produce (mint) one NFT

$15 to sell an NFT$50 at the NFT auction

If at any point you decide to give up on the idea of ​​selling your NFT, you will also have to pay a couple of dollars to destroy your token.

There are many different platforms and blockchains on which you can create and sell your NFTs, and they all have their own advantages and disadvantages for NFT creators. Some of the most popular platforms are Rarible, Opensea and Superrare.

Before choosing a platform that suits your needs, you need to research gas prices and transaction fees beforehand. While Ethereum is a popular blockchain among NFT creators, other popular options include Polkadot, Tezos, Polygon, Binance Smart Chain, and Cosmos.

If you are just diving into the NFT business, follow our instructions for using the OpenSea platform and the Polygon blockchain as this combination allows you to create and host your NFTs for free (no gas fees).

Select the price of your item in ETH and the duration. On OpenSea, the minimum price you can set is $2. If you do not want your NFT to be available immediately, you can set any day in the future as the start date for your sale. OpenSea also allows you to reserve NFTs for a specific buyer. If you choose this option, you need to provide the address of the buyer’s cryptocurrency wallet.

We have set an ambitious price of 1 ETH for our work of art. The price and duration of the sale are two things that you won’t be able to change later, so you shouldn’t rush through this step. We recommend taking a look around to see how many other users are asking for similar artwork before you decide to make your choice.

How to make your own NFT and sell it for free

To complete the NFT transfer, select Complete transfer. OpenSea will ask you to send an e-signature through your crypto wallet.

That’s it, you’ve successfully listed your first NFT on OpenSea! However, minting and listing your NFT is much easier than selling it. In Opensea, you can only choose the duration of the sale. On other platforms, such as Rarible, you can also set up a timed auction or an unlimited auction to improve your chances of selling the token.

Another way to increase your chances is to have social media followers that you can use to promote your art. For example, you can advertise your NFTs on your Instagram account, on your Facebook page, or on dedicated subreddits. You can run small giveaways to promote your collections and get the attention of potential buyers.

A Pro Tip for Selling Your NFTs

NFTs sell well, mostly from established artists (see Beeple and his collection for example) and social media influencers with large followings.

However, for those who are new to the NFT sale, there is also a way to profit from selling your tokens. When you create your NFTs, you need to consider how the buyer can use them in more than one area. In other words, what value does your NFT have other than being a digital asset stored on a blockchain?

If it can be used in one way or another in real life, it is an NFT that has the potential to become popular among buyers and sell. A good example is the STCs that illustrate and raise awareness of the conflict in Ukraine. They are also used to raise funds for charity.
