This comprehensive guide walks you through the entire process of creating and selling NFT tokens without upfront costs. You'll learn about the NFT creation process, how to mint NFTs for free on popular platforms like OpenSea and Rarible, the concept of lazy minting, and effective strategies for selling your digital art. We'll cover wallet setup, platform connection, minting procedures, listing processes, and community-building techniques essential for successful NFT sales.
NFT stands for Non-Fungible Token, which represents unique digital assets that can prove ownership of specific items. Minting an NFT token refers to the process of creating it on a blockchain network, making it verifiable and tradeable.
NFTs can represent virtually anything in the digital space - from tweets and digital artwork in JPG format to music albums and virtual real estate. However, the most significant success NFTs have achieved has been in the digital art collections sector, where artists worldwide can reach collectors and sell their work securely.
With blockchain technology, artists from any location can connect with art collectors and sell their creations in a secure, transparent manner. Anyone can learn how to create and sell NFT art, democratizing access to the digital art market.
The process of tokenizing digital assets, or creating NFTs, traditionally involves gas fees. Most NFTs are created on the Ethereum blockchain, which, despite its popularity, has one major drawback: high gas fees that can make minting prohibitively expensive for new creators.
To create and mint NFTs, you'll need a cryptocurrency wallet such as MetaMask and some Ethereum to cover gas fees. However, this guide demonstrates how to create and sell NFTs for free using both Ethereum and Polygon blockchains, leveraging innovative minting techniques that eliminate upfront costs.
To learn how to sell NFT art profitably, you must first choose an NFT marketplace that allows you to mint your NFTs for free. You'll also need a cryptocurrency wallet to pay any eventual fees and receive payments when your NFTs sell.
You can create and sell NFTs on numerous specialized platforms, each offering different features and benefits. This guide focuses on the most popular NFT trading platforms: OpenSea and Rarible, both of which have established reputations and large user bases.
An important aspect of these popular NFT marketplaces is that they allow free NFT minting through lazy minting technology, though they still charge a service fee of 2.5% of the sale price for each NFT transaction. This fee structure means creators only pay when they successfully sell their work.
MetaMask is one of the most popular cryptocurrency wallets, functioning as a browser extension on your device. It provides secure storage for your digital assets and enables interaction with blockchain applications. If you haven't used it before, visit the MetaMask website and download the wallet extension for your browser.
If you already have a MetaMask wallet, you can import it using your recovery phrase. If not, create a new wallet by following the setup process. Remember to write down your recovery phrase using pen and paper, as this phrase is essential for wallet recovery if you lose access. You'll also need to set a strong password for your wallet to ensure security.
Navigate to the OpenSea marketplace website and click on the wallet icon in the top right corner to connect your wallet. Select MetaMask from the available wallet options and confirm the connection in your wallet popup. After connecting your wallet to the NFT marketplace, you'll be able to view your profile and create your first NFT.
This connection establishes a secure link between your wallet and the platform, allowing you to sign transactions and manage your NFT assets directly through the OpenSea interface.
You can choose between creating a single token or an NFT collection. We recommend minting an NFT collection, as collections tend to be more successful and attractive to collectors than standalone pieces. Collections allow you to establish a cohesive brand and tell a broader artistic story.
To create a single NFT, click Create in the top right menu. If you want to create an NFT collection, click on the account icon (in the top right corner, next to the wallet icon), then select My Collections, and finally click Create Collection.
For each item or NFT you want to create, you'll need to provide several details, including:
Since we're discussing how to create and sell your NFTs for free, it's crucial to select the Polygon blockchain instead of the default Ethereum option. This selection is the key to avoiding upfront minting costs.
Polygon is one of the best networks for NFTs and cryptocurrency transactions because it offers significantly lower fees and higher transaction speeds compared to Ethereum. In this case, it allows OpenSea creators to mint NFTs completely free of charge, eliminating the barrier to entry for new artists.
Click Create, and your first NFT will be minted on the blockchain, ready for listing and sale.
To list your NFT for sale, click Sell in the top right corner of your NFT's page. This opens the listing interface where you can configure your sale parameters.
You can set your desired price for your NFT, choosing between fixed price listings or auction formats. Consider market conditions and comparable sales when pricing your work to maximize your chances of a successful sale.
After setting all the details including price, duration, and any special terms, click Complete Listing, and your NFT will be listed for sale on the OpenSea marketplace, visible to millions of potential buyers.
Note that OpenSea charges a 2.5% service fee, which will be deducted from the price after your NFT sells. This fee covers platform maintenance and transaction processing.
Lazy minting is an innovative process that allows NFTs to be minted at the time of purchase rather than at creation, designed to eliminate any upfront costs for new creators. This technology has revolutionized NFT creation by removing financial barriers to entry.
Lazy minting is a feature available on the most popular marketplaces, including OpenSea and Rarible. It represents a significant technological advancement that has made NFT creation accessible to artists worldwide, regardless of their financial resources.
This NFT creation method was introduced in late 2021 because gas fees proved to be a significant problem for creators, particularly those who are newcomers to the space. Before lazy minting, artists had to pay substantial fees upfront without knowing if their work would sell.
With lazy minting, it's possible to defer the cost of minting an NFT until it's sold to the first buyer. The NFT's data is stored in IPFS, a decentralized file storage system that ensures permanence and accessibility without requiring immediate blockchain registration.
The transaction that assigns the NFT to a buyer is also responsible for the gas fees, meaning the creator doesn't have to bear any additional costs to the platform. This shifts the financial burden from creators to buyers, who are willing to pay these fees as part of their purchase.
Another popular marketplace for NFT art, gaming collectibles, and other NFT assets is Rarible, which offers unique features and a vibrant community of creators and collectors.
This step is identical to the OpenSea process. If you don't have a MetaMask wallet, install and create a wallet on your device following the same procedure outlined earlier. Remember to securely save your secret recovery phrase, as it's the only way to recover your wallet if needed.
Visit Rarible.com and connect your MetaMask wallet by clicking Sign In, then select Sign In with MetaMask. This establishes the connection between your wallet and the Rarible platform.
After confirming the connection to the marketplace from your wallet and accepting Rarible's Terms of Service, you can click Create in the top right corner and create a new NFT on Rarible.
Select the Ethereum blockchain and choose between Single or Multiple NFTs. Selecting "Multiple" means you want to create an NFT collection, which is considered the more popular and potentially profitable option for building a sustainable NFT brand.
Next, you'll need to enter all the details about your new NFT, including:
It's important to select the Rarible collection if you want to use the free minting feature. This selection ensures you won't pay upfront costs.
You must also ensure that the free minting option is enabled. Checking this option means NFTs are only minted when they first sell on the platform, and the buyer pays the gas fees, not the creator.
After entering all the data, scroll down and click Create Item to create your first NFT token on Rarible. The platform will process your submission and make it available for purchase.
Once created, your NFTs will be available for sale on Rarible. However, until someone actually purchases the NFT on the Ethereum blockchain, it won't be registered on that blockchain, demonstrating the lazy minting technology in action.
Now that you've learned how to sell your NFTs on OpenSea and Rarible, you need to focus on two main aspects of NFT sales: building a community around your NFTs and promoting them effectively. Success in the NFT space requires more than just creating good art; it requires strategic marketing and community engagement.
Creating a community around your NFTs is a critical step that every new NFT artist must focus on for long-term success. OpenSea and other popular NFT marketplaces use social proof to verify the authenticity of the artist behind the NFT art, making community presence essential.
OpenSea requires you to link at least one social media channel that you use to manage your NFT collection and share it with your audience. This verification helps establish credibility and trust with potential buyers.
Make it your goal to inform your audience that you're interested in NFTs and actively creating in this space. Spread the word as soon as your first NFT collection launches, creating anticipation and excitement among your followers.
Experts recommend releasing limited edition NFTs to increase your potential profits and follower base. Scarcity creates value and urgency, encouraging collectors to act quickly before missing out on exclusive pieces.
Engage regularly with your community, respond to comments and questions, and create a sense of belonging among your supporters. This ongoing interaction builds loyalty and increases the likelihood of sales and word-of-mouth promotion.
You need to learn how to promote your NFTs to maximize your chances of selling your digital art successfully. You can't simply list them and expect people to buy them without active promotion and marketing efforts.
Your NFTs should be promoted among your followers on all available social media channels, creating multiple touchpoints with potential buyers. Most NFT artists and creative studios use Twitter, Telegram, Discord, and Reddit to stay in touch with their fans and build engaged communities.
Develop a content strategy that showcases your creative process, shares behind-the-scenes insights, and highlights the unique value of your NFT collection. Regular, authentic content helps build trust and interest in your work.
Consider collaborating with other artists, participating in NFT community events, and engaging with collectors to expand your reach. Networking within the NFT space can open doors to new opportunities and exposure.
Now that you know how to sell NFTs on both OpenSea and Rarible platforms, you might wonder which NFT marketplace is better for your needs. The answer depends on your community, established fan base, platform features, and personal preferences.
Ultimately, these are the two most popular NFT marketplaces, and they are quite similar in many respects, both offering robust features and large user bases. However, one important difference is the ability to mint NFTs on different blockchains, which can affect your costs and reach.
OpenSea offers creators the option of Ethereum or Polygon blockchains, with Polygon being the preferred choice for free minting. Rarible offers creators the ability to mint NFTs on Ethereum, Flow, and Tezos, providing more blockchain diversity.
Another feature available on Rarible is the ability to apply for a verified badge, guaranteeing "legitimacy" to potential buyers. Artists may find this feature more appealing as it adds credibility and trust to their profiles, potentially increasing sales and commanding higher prices for their work.
Consider testing both platforms to see which resonates better with your audience and provides the best results for your specific art style and marketing approach.
NFT is a digital asset representing unique ownership on blockchain, impossible to copy. To create NFT: choose blockchain, set up crypto wallet, select NFT platform, upload digital content, define details, click mint button to create, then list for sale.
Creating and selling NFTs is not completely free. Main hidden costs include gas fees for blockchain transactions and platform commissions. While some platforms offer gas-free minting, you typically pay fees when listing or selling your NFTs.
Magic Eden specializes in Solana NFTs with lower fees and faster transactions. Others support multiple blockchains with broader collections. Choose based on your preferred blockchain, trading volume, and fee structure for your needs.
To mint an NFT, you need a crypto wallet, Web3 browser extension, and cryptocurrency for gas fees. No advanced technical background required—basic blockchain understanding helps but is not mandatory for most users.

NFT pricing is determined by creators or issuers. NFTs with unique artistic value, cultural significance, strong community support, and clear utility tend to attract more buyers. Established creator reputation and limited supply also increase buyer confidence and acceptance.
List on popular marketplaces, engage actively on social media platforms like Twitter and Discord, build a strong personal brand, provide detailed descriptions with relevant keywords, participate in virtual events, and interact with collectors to create community interest and trust.
Common NFT scams include phishing attacks, fake marketplaces, pump-and-dump schemes, rug pulls, and counterfeit NFTs. Protect yourself by verifying platform authenticity, using secure wallets, enabling two-factor authentication, researching projects thoroughly, and avoiding suspicious links or unsolicited offers.
