Connecting to OpenSea
Below, we'll teach you how to connect your MetaMask wallet to an NFT Marketplace called OpenSea.
There are many different NFT marketplaces, and each allow you to connect your wallet, create an account, and purchase the NFTs living on certain blockchains. Today, we will walk you through how to connect to OpenSea, but this process will work similarly for any other marketplace you’d like to explore.

What is OpenSea?

OpenSea is the most popular and largest NFT marketplace, where you can purchase, trade and sell NFTs.
There are many types of NFTs on OpenSea including collectibles, digital assets, avatars, trading cards, and art.

Step 1

Step 1 is to navigate to opensea.io and click the profile icon in the top-right corner of the screen.

Wallet type

Next, you’ll need to choose which wallet type you’d like to connect. In our case, it will be Metamask. After selecting Metamask, you will be prompted to connect your wallet. Enter your password, and click “Unlock.”

Wallet connection

You will then need to select the account you would like to connect to OpenSea. If you have multiple MetaMask wallets, all of them will appear as options here. Once you’ve selected your desired wallet, click “Next.” MetaMask will then confirm that the wallet you selected is the account you want to create. Click “Connect.”
It’s always wise to be cautious when connecting your wallet to any website. You need to ensure the website can be trusted before connecting, or else your wallet could be compromised. Thankfully, we can trust OpenSea.

OpenSea profile page

Next, you will be led to your new OpenSea profile page. If you would like to customize your account, click the gear in the upper right-hand corner. In order to make any changes to your OpenSea profile, you will receive an extra security prompt every time. This is a key indicator that this is a safe wallet connection. Click “Sign.”

Profile customization

Here, you can customize your username, bio, email address, profile photo, cover banner and more.

Congrats!

And now, you have successfully connected your MetaMask account to OpenSea! Now, you can begin exploring NFT collections. Each marketplace allows you to browse trending collections, which is a good place to start if you’re not sure which collection to buy from first. You can also browse by top sellers and live auctions.
