How to Create an NFT

What is an NFT?
A non-fungible token (NFT) is a unique digital ﬁle stored on a blockchain (a digital ledger). An NFT
is a cryptographic token, but unlike cryptocurrencies such as bitcoin and many network or utility
tokens, NFTs are not mutually interchangeable, i.e. not fungible.
wikipedia.org/wiki/Non-fungible_token

NFTs Simpliﬁed
Non-fungible tokens are digital assets that contain identifying data recorded in smart contracts
(i.e. the Ethereum blockchain ledger). So it’s like owning a rare baseball card in a digital format and
the ledger shows a record that you own that NFT (and it shows who previously owned that NFT).
As you can see, I clicked a CryptoPunk NFT for
sale on OpenSea marketplace. The blockchain
ledger records the trading history of this NFT
from ETH wallet to ETH wallet.

How to Buy and Sell NFTs on OpenSea
You can create an NFT for free on the website:
OpenSea.io
All you need to get started is a crypto wallet!
We suggest and personally use MetaMask!

MetaMask

MetaMask.io
You will need to create a
MetaMask wallet and fund it with
Ethereum (ETH) before
buying/selling on OpenSea.
MetaMask is the oldest, most
trusted crypto wallet.
➢ Navigate to metamask.io
and click the download
button.
➢ Select your desktop
browser or mobile device.

Install MetaMask
➢ For this example, we are
installing the MetaMask
wallet in our Chrome
browser via the MetaMask
Chrome extension.

Setting Up MetaMask
➢ Once installed, a new tab will open
welcoming you to MetaMask.
➢ Click the “Get Started” button.

Create a Wallet

Seed Phrase
Your “Seed Phrase” is the
backup to your wallet. You will
need to write down these secret
words (in the correct order) and
save them in a safe location.
➢ Save a backup in multiple
places.
➢ Never share the phrase
with anyone.
➢ Compare this to your
credit card number.

MetaMask Wallet
➢ You now have created a
MetaMask ETH wallet and you
can start sending and receiving
Ethereum.
➢ You can also click the “Add
Token” button to add other
cryptocurrencies to your
wallet. For OpenSea, we will
only need ETH.

Fund Your Wallet
➢ In order to buy, create, and sell
NFTs on OpenSea, you will need to
have some ETH in your wallet.
➢ Click the “0x…” number at the top
of your MetaMask account to copy
your wallet address (this is where
you will send ETH).
➢ To learn how to buy and send
cryptocurrency (plus get a FREE

Create Your
OpenSea Account

Create Your OpenSea Account
OpenSea.io

Sign In To Your MetaMask Wallet
➢ This will take you to OpenSea.io/wallet
➢ Click the “Sign In” button to sign into your MetaMask wallet.

Select the ETH wallet
you just created with
MetaMask. Click the
“Next” button.

Click the “Connect”
button.

You are now
“Connected” to your
MetaMask ETH
wallet.

Click the “Sign In”
button once again to
be directed to your
OpenSea proﬁle for
this ETH wallet.

On your OpenSea Account page,
you can edit your proﬁle (image,
name, etc.) and see the NFTs in
your account (ETH wallet).

Now it is time to create your ﬁrst NFT!
Click the “Create” option in the top right
corner. Select “My Collections” in the
dropdown menu.

On your OpenSea My
Collections page, click
the “Create” button.

Create a Collection

To create even a
single NFT, you will
need to create a
Collection ﬁrst. Think
of this as your “brand
name” for your NFTs,
such as CryptoPunks.

Your new collection
will appear here.

Request Review

Click on your new
collection.

Next you’ll submit your OpenSea Collection for review to be veriﬁed on the OpenSea
marketplace. Click the “Edit” button on your Collection page.

On this page you can
edit your NFT
collection details,
such as name, URL,
website, Twitter, etc.
Scroll down…

Toggle on “Submit for
review” and click the
Submit Changes
button.

Create an Item (NFT)

Navigate to your My Collections page.

Click on the Collection
you want to create an
NFT in.

On this Collection page, click on the “Add New Item” button.

It is on this page your
will be creating your
NFT!

Once your NFT is
ready, scroll down
and click the
“Create” button.

Your NFT will now appear on your Collection page.
Your
ﬁrst
NFT!

Sell an Item (NFT)

To sell an NFT, simply click the NFT item on your Collection page.
Click
your
NFT.

On the NFT page, click the “Sell” button.

Post Your Listing For Sale
➢ Set your price. Then click the “Post Your Listing” button.

Initialize Your Account
➢ Before you can list an item
for sale or accept an offer
on OpenSea, you need to
set yourself up for trading.
➢ There's no charge from
OpenSea, but you'll have to
pay a one-time gas fee (the
ETH network transaction
cost) to initialize your
wallet on the blockchain.

Post Your Listing For Sale
➢ Once you’ve initialized your account, you can Post Your Listing for free. You will only be
charged a fee by OpenSea once you sell the NFT (a 2.5% commission).

Buy an Item (NFT)

Buying an NFT is as simple as
searching OpenSea for an item
you want, then bidding, buying
now, or making an offer. Once
you decide to buy an NFT, you
will be connected with your
MetaMask wallet and have to
conﬁrm your purchase.

Coursenvy
Once you complete the
purchase, the NFT you
purchased will permanently be
connected to your wallet
address (and OpenSea Proﬁle).
