Creating an NFT has become one of the most accessible ways for digital artists, creators, and collectors to enter the blockchain space. However, a common misconception is that minting an NFT always comes with high costs—especially on networks like Ethereum, where gas fees can run into hundreds of dollars. The good news? You can create an NFT for free using modern blockchain solutions and smart strategies.
This guide will walk you through two proven methods: lazy minting and using Layer 2 blockchains like Polygon. We’ll also cover platform-specific steps on OpenSea and Rarible, explain potential fees to watch out for, and help you avoid common pitfalls.
What Is an NFT and Why Does Minting Cost Money?
An NFT (Non-Fungible Token) is a unique digital asset verified on a blockchain. Minting refers to the process of uploading your digital file—art, music, video, etc.—to the blockchain, making it a verifiable and tradable token.
On Ethereum, this process requires computational power, which translates into gas fees paid in ETH. These fees fluctuate based on network congestion and can be prohibitively expensive for new creators.
But thanks to innovations like lazy minting and scalable Layer 2 solutions, you no longer need to pay upfront to bring your creation to life.
Method 1: Lazy Minting – Create Without Paying Gas
Lazy minting allows you to list your NFT on marketplaces like OpenSea or Rarible without immediately recording it on the blockchain. Instead, the buyer pays the gas fee when they purchase your NFT—and only then is it officially minted.
This means:
- You create the NFT at no cost.
- The item exists off-chain (usually stored on IPFS) until sold.
- No risk of losing money if your NFT doesn’t sell.

Platforms That Support Lazy Minting
OpenSea
OpenSea enables lazy minting by default. When you upload an item, it’s not immediately added to the blockchain. You only pay gas when accepting offers in certain auction types (more on that later).
Rarible
Rarible offers a “Free minting” toggle during creation. However, this option is only available under the Rarible collection, not custom ERC-721 collections.
⚠️ Note: First-time users may encounter small one-time approval fees (~$10–15) to authorize wallet interactions with smart contracts. This is separate from gas fees and only applies once per contract type (ERC-721 vs ERC-1155).
Potential Downsides of Lazy Minting
While convenient, lazy minting isn’t perfect:
- Limited Visibility: Your NFT won’t appear on external explorers (like Etherscan) until minted.
- No Immutable Proof: Until minted, your work isn’t permanently recorded on-chain.
- Buyer Hesitation: Some buyers may hesitate due to additional minting costs passed to them.
Still, for beginners testing the waters, lazy minting lowers the barrier to entry significantly.
Method 2: Use Polygon – A Gas-Free Alternative
Polygon is a Layer 2 scaling solution built atop Ethereum. It drastically reduces transaction costs while maintaining Ethereum’s security.
On Polygon:
- Minting and listing NFTs are practically free.
- Transactions settle in seconds.
- You can still reach Ethereum-based buyers by bridging assets later.
Best of all, platforms like OpenSea fully support Polygon with seamless integration.
How to Create an NFT on Polygon via OpenSea
Step 1: Set Up Your Wallet
Use MetaMask or another Ethereum-compatible wallet. Ensure it’s connected to the Polygon network (you can add Polygon via Chainlist or manually).
Step 2: Create a Collection
- Go to OpenSea and click your profile icon.
- Select My Collections > Create a collection.
- Fill in details: name, description, logo, social links.
- Set your royalty percentage (typically 5–10%) and enter your payout wallet address.
- Under Blockchain, select Polygon.
- Add supported tokens: Polygon ETH, DAI, USDC, or REVV.
💡 Royalties are automatic payments you receive every time your NFT is resold—a major advantage over traditional art sales.
Creating a collection incurs no gas fees.
Step 3: Mint Your NFT
- From your profile or collection page, click Add Item.
- Upload your file (supports JPG, PNG, GIF, MP4, MP3, GLB up to 100MB).
- Add a name, description, properties, and unlockable content (e.g., high-res files).
- Set supply: 1 for unique items, more for editions.
- Click Create.
✅ Done! OpenSea covers the minimal gas cost—your NFT is now live on Polygon.
How to Sell Your Polygon NFT
Unlike Ethereum, OpenSea currently only supports fixed-price listings for Polygon NFTs (no auctions yet).
To list:
- Visit your NFT’s detail page.
- Click Sell.
- Enter price in Polygon ETH or other supported tokens.
- Choose listing duration (1 day to 6 months).
- Sign the transaction in your wallet.
When sold:
- OpenSea charges a 2.5% service fee.
- You receive payment minus fees directly in your wallet.

Frequently Asked Questions (FAQ)
Can I really create an NFT for free?
Yes. Using lazy minting (on OpenSea or Rarible) or minting on Polygon via OpenSea lets you create NFTs without paying gas fees upfront.
Do I ever have to pay gas fees?
Possibly—but only under specific actions:
- Accepting bids in English auctions (on Ethereum).
- Approving WETH for trading.
- First-time smart contract approvals (~$10–15).
On Polygon, gas fees are negligible and often covered by the platform.
Will my free NFT be less valuable?
Not necessarily. Value comes from art quality, rarity, community, and utility—not how it was minted. Many successful projects use lazy minting or Layer 2 chains.
Can I transfer my Polygon NFT to Ethereum?
Yes. Use the PoS Bridge to wrap your Polygon assets and move them to Ethereum. Note: You’ll pay Ethereum gas fees during this transfer.
Are there royalties on lazy-minted or Polygon NFTs?
Yes! As long as you set a royalty rate when creating a collection, you’ll earn resale royalties regardless of the minting method or chain used.
What happens if my lazy-minted NFT never sells?
Nothing. Since it wasn’t recorded on-chain, there’s no cost or loss. You can edit, relist, or delete it freely.
Final Tips for New Creators
- Start small: Use free minting options to build a portfolio.
- Promote your work: Share on Twitter, Discord, and Instagram.
- Engage communities: Join NFT groups related to your niche.
- Consider giveaways: Distribute free mints to grow a loyal following.
Creating an NFT doesn’t have to be expensive. With tools like lazy minting and efficient blockchains like Polygon, anyone can launch their digital creations—risk-free.
