Navigating the world of NFTs starts with mastering the basics — and one of the most essential steps is connecting your cryptocurrency wallet to a trusted NFT marketplace. OpenSea, the leading decentralized platform for digital collectibles, allows users to buy, sell, and showcase NFTs without needing a traditional account. Instead, everything revolves around your digital wallet.
In this guide, you’ll learn how to seamlessly connect MetaMask (commonly known as the "Fox Wallet") to OpenSea, set up your profile, manage your NFTs, and access your collection from both desktop and mobile devices. Whether you're new to blockchain or expanding your Web3 presence, this step-by-step walkthrough ensures a smooth onboarding experience.
Why Use MetaMask with OpenSea?
Before diving into the setup, it’s important to understand why MetaMask is the go-to wallet for OpenSea users. As a non-custodial cryptocurrency wallet, MetaMask gives you full control over your private keys and assets. When linked to OpenSea, it acts as your identity and payment method across the platform.
OpenSea supports multiple wallets, but MetaMask remains the most popular due to its user-friendly browser extension and mobile app compatibility. Transactions on OpenSea are conducted using cryptocurrencies like Ethereum (ETH) and Polygon (MATIC), both of which are fully supported by MetaMask.

Step 1: Prepare Your MetaMask Wallet
If you haven’t already created a MetaMask wallet, now is the time. Here’s how:
- Install the MetaMask browser extension from metamask.io (avoid third-party sources).
- Follow the setup wizard to create a new wallet.
- Securely store your 12-word recovery phrase — never share it with anyone.
- Once set up, you can fund your wallet with ETH or MATIC for gas fees and purchases.
🔐 Security Tip: Your recovery phrase is the key to accessing your funds. Store it offline — never in screenshots, emails, or cloud storage.
With your wallet ready, you're one step closer to entering the OpenSea ecosystem.
Step 2: Connect MetaMask to OpenSea
Connecting your wallet to OpenSea is simple and takes less than a minute:
- Go to opensea.io — always verify the URL to avoid phishing sites.
- Click the profile icon in the top-right corner.
- Select “Connect Wallet”.
- Choose MetaMask from the list of options.
- Confirm the connection in your MetaMask popup by clicking “Next”, then “Connect”.
You’re now logged into OpenSea! No username or password required — just your wallet.
Step 3: Customize Your OpenSea Profile
After connecting, personalize your profile so others can recognize your digital identity:
- Click the profile icon again and select “Settings”.
- Upload a profile picture (recommended size: 200x200 pixels) and a cover banner (1500x500 pixels).
- Fill in optional details like your bio, social links, and display preferences.
- Click “Save” — OpenSea will send a verification email to confirm ownership.
Within minutes, you’ll receive an email with a “Verify My Email” button. Click it to complete verification and unlock full profile functionality.
💡 You can update your cover image later by hovering over it on your profile page and clicking the pencil icon when it appears.
Step 4: Locate Your Wallet Address
Your wallet address is a unique identifier starting with 0x — essential for receiving NFTs or cryptocurrency transfers.
There are two easy ways to find it:
- From MetaMask Extension:
Click the fox icon in your browser toolbar. Your address appears at the top — click it to copy automatically. - From OpenSea Profile:
On your profile page, click the0x...address beneath your username. A “Copy” tooltip will confirm successful copying.
Once copied, you can safely share this address to receive NFTs from friends or creators.
Step 5: Unhide Hidden NFTs
Did you receive an NFT but can’t see it on your profile? Don’t worry — OpenSea automatically hides incoming NFTs by default.
To reveal them:
- On your profile, switch to the “Hidden” tab.
- Find the NFT you want to display and click the “…” menu.
- Select “Unhide”.
- Confirm the action in the pop-up banner.
The NFT will now move to your “Collected” section and be visible to visitors.
To re-hide an item later:
- Click “…” on the NFT.
- Choose “Hide” — a confirmation message will appear.
This feature helps keep your profile clean while giving you control over what’s publicly shown.
