Connecting a cryptocurrency wallet to OpenSea is the essential first step for anyone looking to explore the world of NFTs. Whether you want to mint, buy, or sell digital assets, you'll need a compatible wallet to interact securely with the platform. OpenSea supports several popular wallets, including MetaMask, Coinbase Wallet, and Trust Wallet—each offering unique features and user experiences.
This comprehensive guide walks you through the step-by-step process of connecting these wallets to OpenSea, ensuring a smooth onboarding experience. We’ll also address common issues and provide actionable solutions to help you get started without delays.
Why You Need a Crypto Wallet for OpenSea
Before diving into the setup, it's important to understand why a crypto wallet is required. OpenSea operates on blockchain technology—primarily Ethereum—meaning all transactions (like buying or minting NFTs) require cryptocurrency and gas fees. A crypto wallet serves as your digital identity and transaction tool on the blockchain.
The most widely used wallets include:
- MetaMask: Ideal for Ethereum-based interactions.
- Coinbase Wallet: Offers strong security and integration with decentralized apps.
- Trust Wallet: Supports multiple blockchains and is mobile-first.
All three allow you to securely sign transactions and manage your NFTs directly from your device.

How to Connect MetaMask to OpenSea
MetaMask is one of the most popular choices for OpenSea users due to its seamless integration with Ethereum-based dApps. Here's how to connect it.
Step 1: Install MetaMask (Skip If Already Installed)
Begin by downloading the MetaMask mobile app from the App Store (iOS) or Google Play Store (Android). Search for “MetaMask” and install the official app.
Once installed, open the app and follow the prompts to create a new wallet. During setup:
- Set a strong password.
- Write down and securely store your 12-word recovery phrase—this is critical for wallet recovery if you lose access.
Never share your recovery phrase with anyone.
Step 2: Open the OpenSea App and Access Profile
Download and launch the OpenSea app on your mobile device. Navigate to the bottom menu and tap on “Profile”.
You’ll be prompted to connect a wallet. From the list of options, select “MetaMask”.
Step 3: Confirm Connection in MetaMask
After selecting MetaMask, the MetaMask app will automatically open. You’ll see a request asking whether you’d like to allow OpenSea to view your public address.
Tap “Connect” to confirm. Once approved, return to OpenSea—you should now see your wallet address displayed, indicating a successful connection.
If the connection fails, try force-closing both apps and repeating the process.

How to Connect Coinbase Wallet to OpenSea
Coinbase Wallet offers robust security and is especially useful for users who prefer non-custodial control over their assets. Note that this connection currently only works via OpenSea’s desktop website, not the mobile app.
Step 1: Install Coinbase Wallet (Skip If Already Installed)
Download the Coinbase Wallet app from your device’s app store. After installation, open it and create a new wallet by following the on-screen instructions.
Just like with MetaMask, securely back up your recovery phrase during setup. This phrase is your sole means of recovering funds if you lose access.
Step 2: Link Wallet via OpenSea Desktop
On your computer, go to OpenSea.io and click on the profile icon in the top-right corner. Select “Profile”, then choose “Coinbase Wallet” from the available options.
A pop-up window will appear displaying a QR code.
Step 3: Scan QR Code Using Coinbase Wallet App
Open the Coinbase Wallet mobile app and tap the QR scanner icon (usually found on the home screen or under "Connect"). Point your camera at the QR code on your computer screen.
Once scanned, confirm the connection request. You’ll be redirected to OpenSea, where your profile will be automatically created using your wallet address.
⚠️ Reminder: The Coinbase Wallet integration does not work on mobile browsers or the OpenSea mobile app—use desktop only.
How to Connect Trust Wallet to OpenSea
Trust Wallet is another excellent option, especially for users interested in multi-chain support beyond Ethereum. Connecting it to OpenSea is straightforward.
Step 1: Install Trust Wallet (Skip If Already Installed)
Search for “Trust Wallet” in your app store and download the official app. After opening it, follow the setup steps to create a new wallet.
Make sure to:
- Set a secure password or enable biometric login (Touch ID/Face ID).
- Safely store your recovery phrase offline.
Step 2: Connect Through OpenSea Mobile App
Launch the OpenSea app, navigate to “Profile”, and select “Trust Wallet” from the list of available wallets.
The Trust Wallet app will open automatically with a connection prompt.
Step 3: Approve Connection
Tap “Connect” in Trust Wallet to grant OpenSea access to your public address. Return to OpenSea—you should now see your wallet linked and ready for use.
Some users report occasional glitches requiring multiple attempts. If the connection fails:
- Force-close both apps.
- Restart your phone.
- Try again.
