In this post, I will show you how to mint NFTs with Metamask from start to finish. Also, I will show you how to protect your metamask wallet from hackers.

So, lets get started.

How to Mint an NFT with MetaMask

Minting NFT with Metamask needs an extra step. First, you need to download the Chrome extension, create an account, fund it with ethereum, and look for a marketplace before you start minting your NFT.


Here is a step-by-step guide on how to mint NFT with Metamask.

Step 1: Choose A marketplace.

The first step to minting an NFT with metamask is to choose an NFT marketplace. Today, we have a variety of marketplaces that help their users tokenize their digital assets for monetization.

Popular NFT marketplaces are OpenSea, Rarible, SuperRare, Foundation, Nifty Gateway, etc. Even some cryptocurrency exchanges have started adopting this technology. So you need to pick one of these marketplaces to mint your NFTs.

Note: Not all marketplaces integrate with Metamask; in this tutorial, I’ll show you how to mint NFT with Metamask on Opensea, which is one of the marketplaces that allows you to mint NFT for free. If you want to mint in another marketplace but do not know if they integrate with Metamask, do check it here.

Step 2: Download and set up a Metamask wallet.

If you chose another marketplace to mint your NFT, then the steps might be different. If you chose OpenSea, then you are going to find everything same to what I am going to do here.

To get started, you first need to download Metamask for either the Chrome extension, iOS, or Android. Click on this link and you should see a page like this:

You can install the wallet app on iOS or Android depending on your convenience, but whichever one you choose, the process remains the same.

In my case, I am going to install the Chrome extension. After installing, click on “Get started.” You will be taken to a page like this:

If you don’t have a metmask account yet, click on “Create account”.

Then choose a password  and click on create.

Then copy your recovery phrase and keep it secure.

Confirm your secret recovery phrase by entering it in the order you copied it.

Step 3: Fund Your Metamask Wallet with Ethereum.

There are some charges associated with minting NFT in any market place. These fees are used to pay miners who create blocks that will be used to tokenize your digital assets. So you need to fund your Metamask wallet to pay these minting fees.

In addition to the minting fees, you need to initialize your account if you are minting for the first time, and there are some charges to do that. Account initialization costs between $100 and $300.

However, if you are using another blockchain like Polygon, you don’t necessarily need to fund your metamask wallet. NFT minting on polygons blockchain is free.

You can fund your Metamask wallet with Ethereum in the following ways:

  • Buying ETH directly on Metamask
  • Transferring from a ledger wallet to a metmask wallet
  • Transferring from an exchange.

In this guide, I will show you how to fund your wallet by transferring from an exchange (Binance).

Take the following steps to buy Ether on Binance and transfer it to your Metamask wallet

  • Login to your Binance account.
  • Make a USD deposit into your Binance account.
  • Navigate to the “markets” page.
  • Find a pair of ETH and USD
  • Select “Buy”
  • Enter the amount of ETH that you want to buy.
  • Pay attention to fees.
  • Then complete the purchase.
  • Then Navigate to the wallet page.
  • Click on withdrawal.
  • Copy your Metamask ETH wallet address to the withdrawal page of Binance.
  • Input the amount ETH you want to transfer and complete the transaction.
  • If the transfer was successful, it will reflect on your Metmask wallet.

Step 3: Connect your Metamask Wallet to NFT marketplace

Visit OpenSea and click on the “Wallet Icon” at the top-right corner. Choose Metamask Wallet and confirm the connection when prompted.

Risk Involved In Minting NFT with Metamask Wallet

There is a certain risk that, if not checked, could cause losses on minting your NFTs in any marketplace. One of them is crypto Volatility, the second is phishing activities and others. Let’s go through them one-by-one.

1) Crypto Volatility:

The value of cryptocurrency goes back and forth, so the value of any crypto you purchased for gas fees can fall.

2) Compromised Seed Phrase

Many people have lost their crypto assets and even NFTs to some scammers through phishing sites. These scammers design a phishing system that prompts users to input their wallet seed phrase in order to get a free NFT or other offer.

So, be vigilant and do not release your wallet seed phrases as you trade NFTs.

3) Wrong Transaction

Minting and trading of NFTs usually involves buying and transferring crypto assets from one wallet to another. If you are not conversant with these transactions, you need to educate yourself before you begin minting NFT.

Any cryptocurrency asset sent to the wrong wallet address is lost and you will never recover it.
