Beginner’s Guide to NFTs: How To Mint a Non-Fungible Token on Ethereum

·

NFTs, or non-fungible tokens, are blockchain-based tokens that prove ownership and provenance of digital items such as images, video files, and even physical assets.

They’ve gained immense popularity recently, with multi-million dollar sales of NFT artwork making headlines. Twitter profiles flaunt NFT avatars like Bored Ape Yacht Club, CryptoPunks, and Pudgy Penguins. Even major brands and celebrities have embraced NFTs—but how do you create one?

Minting an NFT ("creating on the blockchain") is straightforward with this beginner-friendly guide. We’ll focus on Ethereum, the leading blockchain for NFTs, and OpenSea, the top NFT marketplace.


Step 1: Get a Crypto Exchange Account

To mint an NFT—or engage in crypto—you’ll need an account on a crypto exchange like Coinbase or Kraken. These platforms let you buy and sell cryptocurrencies.

Why? You’ll need Ethereum (ETH) to pay for minting fees (explained later). Plus, if your NFT sells, you can cash out or trade earnings.

  2. Enter your MetaMask public address (starts with "0x").
  3. Confirm the transaction.

Step 5: Sign Up for OpenSea

  1. Unlock MetaMask (click the fox icon).
  2. Visit OpenSea.
  3. Click "Profile" → "Connect Wallet" → MetaMask.
  4. Sign terms via MetaMask and verify your email.

Step 6: Mint Your NFT

  1. Click "Create" (top-right).
  2. Upload your file (image, video, etc.).
  3. Name your NFT and add a description (optional).
  4. Click "Create"—your NFT is minted!
