The world of non-fungible tokens (NFTs) has exploded in popularity over the past few years, transforming how creators monetize digital art, music, collectibles, and more. From independent artists like Beeple to global brands such as Nike, VISA, and adidas, NFTs have opened new frontiers in ownership, creativity, and digital engagement.
With this surge, NFT minting—the process of turning digital files into blockchain-verified assets—has become accessible to virtually anyone. This guide will walk you through everything you need to know about creating your own NFTs, from choosing a platform to listing your first piece for sale.
What Is NFT Minting?
NFT minting is the act of permanently recording a digital file—such as an image, video, or audio clip—onto a blockchain. Once minted, the asset becomes a verifiable, unique token that cannot be altered or duplicated.
Contrary to popular belief, you don’t need advanced coding skills to get started. As Denise Schaefer, co-founder of Surge, puts it:
“There’s a big misconception that you have to be technical in order to participate in crypto. I look at NFTs as a fun entryway into the space that doesn’t require coding skills.”
Whether you're an artist, musician, or digital enthusiast, minting your first NFT can be a simple and rewarding experience.

How to Mint NFTs: Step-by-Step on OpenSea
While multiple platforms support NFT creation, OpenSea remains the largest and most user-friendly marketplace for Ethereum-based NFTs. Here’s how to create your first NFT:
1. Connect Your Crypto Wallet
Begin by linking a compatible cryptocurrency wallet—like MetaMask—to OpenSea. Click “Profile” in the top-right corner and select your wallet. After installing the MetaMask extension (if you haven’t already), accept the terms and click “Sign” to authenticate.
No fees are incurred during this step—this is just a security handshake between your wallet and the platform.
2. Set Up Your Profile
Personalize your OpenSea presence with a username, profile picture, banner, and bio. You can also add links to your social media or personal website. Verify your account via email to unlock full functionality.
3. Create Your NFT
Click the “Create” button next to your profile. Upload your digital file (supports JPG, PNG, GIF, MP3, MP4—up to 100 MB). Then:
- Give your NFT a name
- Add a description (optional)
- Include an external link (optional)
- Set a royalty percentage (e.g., 5–10%) for future resales
- Choose the supply (number of copies)
- Select the blockchain: Ethereum or Polygon
Click “Create”, and your NFT is now minted—but not yet for sale.
4. List Your NFT for Sale
Click “Sell” to set a price. You can choose:
- Fixed price
- Timed auction
OpenSea charges a 2.5% service fee on each sale. To finalize the listing, you’ll need to pay a one-time gas fee to “initialize your wallet.” This only applies the first time you list an item.
Ensure your wallet has enough ETH or MATIC to cover gas costs before confirming the transaction.
Minting NFTs Using a Smart Contract Address
Sometimes, official minting websites crash due to high traffic. In such cases, minting directly from a smart contract via Etherscan offers a reliable workaround—but it requires caution.
1. Find the NFT Smart Contract Address
Locate the contract address on the project’s official website, social media, or OpenSea’s Details tab.
2. Search Etherscan
Paste the contract address into Etherscan.io. Navigate to the Contract tab, then click Write Contract and connect your wallet via Connect to Web3.
3. Start Minting
Look for the mint function (e.g., mintPineapple). Enter:
- The mint price
- Number of tokens
Click Write, then confirm the transaction in MetaMask—including gas and minting costs.
⚠️ Warning: Only use verified contracts. Malicious ones can steal funds.
👉 Securely manage your digital assets with trusted tools.
Minting on Non-Ethereum Blockchains
Ethereum’s high gas fees have driven creators toward more affordable alternatives. Here are four popular blockchains for low-cost NFT minting:
Solana
Platforms like SolSea offer fast, low-fee minting:
- Connect a wallet like Phantom
- Upload files (up to 10 MB)
- Add name, description, royalties, and metadata
- Click “Mint NFT”
Solana transactions cost pennies and settle in seconds.
Polygon
Using NFT Minter:
- Connect your Polygon wallet
- Upload media (JPG, PNG, MP4 – max 10 MB)
- Enter title, description
- Choose token type (ERC721 or ERC1155)
- Submit
Minting completes in minutes with minimal fees.
Cardano
With the Cardano Token and NFT Builder:
- Connect Daedalus or Yoroi wallet
- Select “NFT”
- Upload file (up to 15 MB)
- Fill in metadata
- Pay in ADA
Files are stored on IPFS, ensuring decentralization.
Binance
On Binance NFT Marketplace:
- Click “Create”
- Upload file (up to 50 MB)
- Name and describe your NFT
- Choose BEP-721 (single) or BEP-1155 (multiple)
- Pay tiny minting fee (as low as 0.000001 BNB)
Binance stores data centrally but offers seamless integration with its exchange ecosystem.
Minting from Third-Party Websites: Risks & Precautions
Some projects offer direct minting through their own websites. While convenient, these platforms can pose risks:
- Fake sites mimicking real projects
- Malicious code that drains wallets
- Unverified smart contracts
How to Stay Safe:
- Always verify the URL begins with
https://and matches official sources - Cross-check links with the project’s verified social media
- Never connect your wallet unless you’re certain of the site’s legitimacy
When in doubt, stick to well-known marketplaces like OpenSea or SolSea.
