How to Mint an NFT in 2026: A Complete Step-by-Step Guide
Minting is the moment your NFT goes from a file on your computer to a permanent token on the blockchain. It's easier than it sounds — and in 2026, you don't need to write a single line of code to do it. Here's the full process.
01 — Prepare Your Art and Metadata
Before you can mint, you need two things ready: your images and your metadata JSON files. Each NFT in your collection needs a corresponding JSON file describing its name, image URL, and traits.
Use TheMintLab's generator to produce both your images and metadata automatically from your art layers. Then upload everything to IPFS via Pinata to get your base URI.
Not ready yet? Read our guide on NFT metadata and how to upload to Pinata first — then come back here to mint.
02 — Set Up Your Wallet
You need a crypto wallet to deploy your contract and receive payments. The most widely supported option is MetaMask — a browser extension available for Chrome, Firefox, and Brave.
- Install MetaMask from metamask.io
- Create a new wallet and save your seed phrase somewhere secure — never share it
- Add the network you plan to mint on (Polygon, Base, or Ethereum are already listed by default)
- Fund your wallet with enough ETH or MATIC to cover gas fees
Security first: Your seed phrase is the master key to your wallet. Store it offline. Anyone who has it controls your wallet and all NFTs inside it.
03 — Choose Your Minting Platform
You don't need to write a smart contract from scratch. These platforms deploy production-grade contracts for you:
| Platform | Best For | Chains Supported |
|---|---|---|
| Manifold | Custom contracts with full ownership | Ethereum, Base, Polygon |
| ThirdWeb | Developer-friendly, lots of contract types | 700+ chains |
| Zora | Creator-first, built-in marketplace | Zora Network, Base, Ethereum |
| OpenSea (lazy mint) | Zero upfront cost, beginners | Ethereum, Polygon |
For a first generative collection, Manifold or ThirdWeb give you the most control. Connect your MetaMask wallet, select an ERC-721 contract, and deploy.
04 — Deploy Your Smart Contract
On Manifold or ThirdWeb, deploying a contract takes about five minutes:
- Connect your wallet
- Select ERC-721 (standard for unique 1-of-1 NFTs per token)
- Enter your collection name, symbol, and base URI (your IPFS metadata folder CID)
- Set your royalty percentage (5–10% is standard)
- Click Deploy — confirm the transaction in MetaMask
Once deployed, your contract address is live on-chain. You'll use this address to list on marketplaces.
05 — Mint Your Tokens
After deployment, you mint tokens through your contract. Some platforms let you batch mint — creating all 1,000 or 10,000 tokens in one transaction. Others mint on demand as collectors purchase.
Batch minting costs more gas upfront but makes all tokens available immediately. Lazy minting defers gas costs until mint time — better for reducing your upfront risk.
06 — List on a Marketplace
Once minted, import your contract to OpenSea, Blur, or Magic Eden by entering your contract address. Your collection will appear with all traits and images pulled from your metadata automatically.
Set your mint price, configure your allow list if you have one, and you're live.

What does minting an NFT mean?
Minting is the process of recording your NFT permanently on a blockchain. Once minted, the token exists on-chain with a unique ID linked to your metadata and image.
How much does it cost to mint an NFT?
It depends on the blockchain. Minting on Ethereum can cost $10–$100+ in gas fees. On Polygon or Base the cost is near zero. Lazy minting options on OpenSea let you defer gas costs until the NFT sells.
Do I need a smart contract to mint NFTs?
For a full collection, yes — but you don't need to write one yourself. Platforms like Manifold, ThirdWeb, and Zora let you deploy a production-grade contract with no coding.
What wallet do I need to mint NFTs?
MetaMask is the most widely supported wallet for NFT minting on Ethereum and EVM-compatible chains. For Solana, Phantom is the standard choice.
Can I mint NFTs for free?
Yes — on Polygon and Base, gas fees are near zero. OpenSea also offers lazy minting where you list for free and only pay gas when a sale occurs.
