Coinbase Wallet Extension: Setup, Security & Web3 Access
The coinbase wallet extension is a browser-based gateway to decentralized finance, NFTs, and thousands of crypto apps—all without leaving your desktop. Launched by Coinbase around 2021, this browser extension runs natively in Chrome and other Chromium-based browsers like Brave and Microsoft Edge, allowing users to interact with Web3 directly from the tab they’re already working in. The Coinbase Wallet extension is a non-custodial browser extension that allows users to store, send, and manage cryptocurrencies and NFTs securely.
Unlike a standard Coinbase exchange account where the platform holds your funds, the Coinbase Wallet browser extension is a self custody wallet. This means only you control your private keys and recovery phrase. Coinbase cannot access your funds, reset your password, or recover your wallet if you lose your backup. It’s a fundamentally different security model—and a powerful one for users who want complete ownership over their crypto assets.
The key difference between Coinbase.com and Coinbase Wallet is in how your assets are managed and who controls them. Coinbase.com is a centralized brokerage platform where Coinbase holds your crypto on your behalf, similar to how a bank holds your money. In contrast, Coinbase Wallet is a non-custodial, self-managed wallet, giving you direct control and ownership over your digital assets—your money is in your own hands, not held by a third party. This distinction means you are responsible for your own security and have full autonomy over your funds and private keys, providing a higher level of privacy and control.
Core use cases include managing ETH and ERC-20 tokens, collecting and viewing NFTs, connecting to DeFi protocols like Uniswap or Aave, and exploring Web3 games without needing mobile confirmation for every transaction. Google services like Chrome and Google Password Manager can help you install and securely manage access to the extension, though you should never store your recovery phrase in any cloud-based tool.
The Coinbase Wallet extension supports multi-chain assets, including Ethereum, Solana, Polygon, Avalanche, BNB Chain, Bitcoin, Dogecoin, and Litecoin.
Introduction to Coinbase Wallet
Coinbase Wallet is a self-custody digital wallet designed to give users complete control over their crypto assets and private keys. Unlike custodial wallets, where a third party holds your funds, the Coinbase Wallet ensures that only you have access to your digital assets, making it a truly non-custodial wallet. With Coinbase Wallet, you can securely store, manage, and trade a wide variety of cryptocurrencies, as well as interact with decentralized apps (dApps) and crypto apps directly from your browser or mobile device.
The wallet is available as both a mobile app and a browser extension, providing convenient access across multiple devices. Whether you prefer managing your assets on the go or from your desktop, Coinbase Wallet makes it easy to stay connected to the world of Web3. To get started, users can download the Coinbase Wallet app from the official Coinbase website or install the browser extension directly from the Chrome Web Store. This flexibility allows you to access your wallet, manage your crypto assets, and explore decentralized apps wherever you are, all while maintaining full control and security over your private keys.
How to Install the Coinbase Wallet Browser Extension
Getting started requires a quick download from the official chrome web store. The process takes under two minutes, but verifying you’re installing the legitimate extension is critical to protecting your funds.
Step-by-step installation:
Open Chrome, Brave, Microsoft Edge, or another Chromium-based browser on your computer
Navigate to Google and search “Coinbase Wallet extension”
Click the result pointing to the Chrome Web Store (URL should start with chrome.google.com/webstore)
Verify the publisher is listed as “Coinbase Wallet” with the official coinbase branding
Click “Add to Chrome” and confirm any permission prompts
Wait for the extension to download and install automatically
Once the Coinbase Wallet extension is installed, tap (or click) on the extension icon. You can then select 'Create a new wallet' or 'I already have a wallet' to proceed with the setup process.
The wallet extension runs locally in your browser, storing encrypted key data on your device rather than on Coinbase’s or Google’s servers. File size is minimal, and performance impact is negligible for modern computers.
After installation, pin the extension icon to your Chrome toolbar for convenient access. Click the puzzle piece icon in Chrome, find Coinbase Wallet, and click the pin icon. To access important wallet information, tap (or click) on options like 'Show Wallet address' or 'Show Recovery Phrase' within the extension interface. While the extension works well alongside other Google services like Drive or Docs for researching decentralized apps, never use cloud tools to store your 12 word recovery phrase.
Create a New Wallet in the Extension
If you don’t already have a self-custody wallet, you can create a new wallet directly in the extension. The most important part of this process is properly backing up your 12-word recovery phrase—this is the master key to your digital assets.
Wallet creation flow:
Click the Coinbase Wallet extension icon in your browser toolbar
Select “Create new wallet”
Accept the terms of service
Choose a web3 username (this will be visible to others on supported networks)
Write down your 12-word recovery phrase exactly as displayed
The recovery phrase is generated locally in your browser using cryptographic randomness. Coinbase has no record of it. If you lose this phrase, no one—not Coinbase, not Google, not any support team—can help you recover your wallet.
Critical backup rules:
Write the phrase on paper, not in a screenshot or digital note
Store copies in two separate secure locations (like a home safe and a bank deposit box)
Never email, text, or save the phrase in Google Docs, iCloud Notes, or any cloud storage
Never share it with anyone claiming to be “support”
After writing down your phrase, the extension will ask you to verify it by re-entering some or all of the words. This confirms you’ve actually backed it up. Then you’ll set a strong password that encrypts the wallet on your specific device.
For password best practices, use a unique, long passphrase—something like four random words strung together. You can store this password in a reputable manager like Google Password Manager, but keep the 12-word phrase strictly offline.
Once complete, your wallet is ready to connect to dapps, receive crypto, and display token and NFT balances in the extension UI.
Import an Existing Wallet to Coinbase Wallet Extension
Already have a wallet from MetaMask, Trust Wallet, Phantom, or another provider? You can import it to the Coinbase Wallet extension using your existing recovery phrase. Your assets aren’t “moved”—they’re simply accessed from a new interface.
General import process:
Click the Coinbase Wallet extension icon
Select “I already have a wallet” or “Import an existing wallet”
Choose “Import recovery phrase”
Type or paste your 12-word phrase in the correct order
Create a new local password for the extension
Recovery phrases are standardized using BIP39 for most EVM wallets, making them portable across providers. Note that passwords are provider-specific: your MetaMask or Trust Wallet password won’t transfer. You’ll create a fresh password just for Coinbase Wallet.
Finding your recovery phrase in other wallets:
Wallet
Navigation Path
MetaMask
Settings → Security & Privacy → Reveal Secret Recovery Phrase (enter password)
Trust Wallet
Settings → Wallets → Options → Show or Manual
Phantom
Settings → Show Secret Recovery Phrase
Solflare
Avatar → Export mnemonic → Show
When importing, double-check each word and spacing. Avoid pasting from clipboard managers or cloud-synced notes—type manually if possible. A single typo can result in accessing the wrong wallet or failing to import altogether.
Connect and Use a Ledger Hardware Wallet with the Extension
For users who want an additional layer of security, the wallet extension supports Ledger hardware devices like the Nano S Plus or Nano X. This setup keeps your private keys on physical hardware while using the extension as your interface.
Prerequisites:
Ledger Live installed on your computer
Ethereum app (or applicable network app) installed on the Ledger device
Device connected and unlocked with the correct app open
Connection steps:
Open the Coinbase Wallet extension
Select “Import an existing wallet”
Choose “Connect Ledger wallet”
Plug in your Ledger via USB (or use Bluetooth if supported)
Approve connection prompts on both the extension and the device
Confirm “Allow Ledger Manager” on the device screen
Select which derived address to use in the extension
The security model here is significant: private keys never leave the Ledger hardware. The extension requests transaction signatures, but every transaction must be physically confirmed on the device screen. This provides protection even if your computer is compromised.
You can link one Ledger with multiple addresses and manage them within the extension, making it practical to separate trading activity from long-term storage.
Funding the Coinbase Wallet Extension
Before you can swap tokens on a DEX, mint NFTs, or interact with DeFi protocols, you need crypto in your wallet. Funding can come from your Coinbase account, other exchanges, or external self-custody wallets.
Option 1: Transfer from Coinbase.com
Open the extension and navigate to the Assets tab
Click “Buy (+)” then “Connect my Coinbase account”
Authorize the connection on Coinbase.com
Select the asset (ETH, USDC, DAI, etc.)
Choose amount, review fees, and confirm
Option 2: Buy crypto directly
If you don’t have crypto yet, the extension supports purchases in over 130 countries:
Connect your Coinbase account from the extension
Choose asset and funding method (bank transfer or card where applicable)
Review network and Coinbase fees
Complete the purchase
Option 3: Manual transfer from Coinbase.com
Log into Coinbase.com
Click “Send / Receive” then “Send”
Copy your wallet address from the extension (click “Show Wallet address”)
Paste the address into Coinbase
Select the correct network (e.g., Ethereum mainnet, Base)
Confirm and wait for blockchain confirmations
Option 4: Transfer from other wallets
Copy your wallet address or scan the QR code from the extension
Open MetaMask, Trust Wallet, or your source wallet
Choose Send, select asset and chain
Paste or scan the address and confirm
Always keep some of the network’s native token (ETH on Ethereum, MATIC on Polygon) in your wallet to cover future network fees for transactions.
Double-check the network and address format before sending. Sending funds to an unsupported network or wrong address can result in permanent loss.
Wallet Extension Features
The Coinbase Wallet browser extension offers a robust set of features that make managing your crypto assets and interacting with the decentralized web both secure and convenient. Here’s what users can expect from the wallet extension:
Secure storage: Your private keys and digital assets are stored in a secure location on your device, never shared with Coinbase or any third party.
Multi-network support: Manage a wide range of cryptocurrencies across different blockchain networks, all from a single wallet extension.
Direct dApp interaction: Seamlessly connect to DeFi protocols, NFT platforms, and other crypto apps without leaving your browser.
App integration: Easily connect the browser extension to the Coinbase Wallet app for unified asset management across multiple devices.
Streamlined transactions: Sign blockchain transactions directly within your browser, making trading and asset transfers fast and efficient.
Browser compatibility: The wallet extension works with popular browsers like Chrome, Brave, and Edge, ensuring broad accessibility.
Wide dApp access: Instantly connect to leading decentralized apps such as Uniswap, OpenSea, and more, expanding your Web3 experience.
Flexible wallet management: Create a new wallet or import an existing one using a 12-word recovery phrase, giving you full control over your crypto assets.
Enhanced security: Protect your wallet with a strong password and optional two-factor authentication for secure access.
QR code support: Easily transfer funds and assets by scanning QR codes, simplifying the process of sending and receiving crypto.
Comprehensive transaction history: View detailed transaction history and asset details directly in the extension, making it easy to track and manage your portfolio.
Multi-device access: Use the wallet extension and app across multiple devices, so you can access your wallet and manage your assets wherever you are.
With these features, the Coinbase Wallet browser extension empowers users to securely access, manage, and grow their crypto assets while exploring the full potential of decentralized apps and the Web3 ecosystem.
Using the Coinbase Wallet Extension with Web3 dapps
The primary advantage of the Coinbase Wallet browser extension is seamless connection to decentralized apps directly from your desktop browser. No mobile app required, no QR code scanning for every transaction.
Standard connection pattern:
Visit a dapp using Chrome (Uniswap, OpenSea, Aave, Base ecosystem apps)
Click “Connect Wallet” on the site
Choose “Coinbase Wallet” or “WalletConnect”
Approve the connection popup in the extension
The connection only shares your public address and view permissions—not your private keys or ability to sign transactions without explicit approval.
Transaction previews and confirmations:
The extension displays transaction details before you sign:
Estimated gas fees
Token amounts being sent or received
Contract interactions
Network being used
Every transaction requires explicit confirmation in the extension window. If you’re using a connected Ledger, you’ll also confirm on the hardware device.
Best practices for dapp security:
Verify site URLs via Google Search or bookmarks before connecting
Look for the HTTPS lock icon in the address bar
Avoid clicking wallet-connect links from ads or unknown sources
Review what permissions a dapp is requesting before approving
You can view transaction history, token balances, NFTs, and recent dapp connections inside the extension interface. The mobile coinbase wallet app isn’t required for desktop usage, though you can use both with the same recovery phrase.
While Chrome’s Safe Browsing and phishing detection features provide some protection, they can’t catch everything. Only approve transactions you fully understand.
Managing Multiple Wallets and Accounts in the Extension
The Coinbase Wallet extension supports multiple wallets, including different recovery phrases and at least one Ledger-connected wallet. This is useful for separating trading activity, DeFi positions, and NFT collections.
Adding another wallet:
Click your username or profile icon in the extension
Select “Add and manage wallets” (or similar menu option)
Choose “Import a wallet” or “Create a new wallet”
Follow the prompts to attach an additional recovery phrase
You can switch between wallets and addresses from this menu. Each stored wallet should have its own securely backed-up 12-word phrase in a separate secure location.
Removing wallets:
Before removing any wallet from the extension, verify that you have the recovery phrase backed up offline. Once removed, re-importing requires the phrase—there’s no other recovery method.
For additional operational security, consider using separate Chrome browser profiles (personal vs. work Google Account profiles) to logically isolate different wallet usage patterns.
Security, Recovery Phrases, and Network Fees
The Coinbase Wallet is a non custodial wallet. Only you control your keys. Neither Coinbase nor Google can reset passwords or restore lost recovery phrases. This is both the power and the responsibility of self-custody.
What is a recovery phrase?
A 12-word sequence generated during wallet creation. It’s cryptographically linked to your private keys and can recreate access to your wallet on any compatible extension or app. Anyone with this phrase has complete control over your funds.
Non-negotiable safety rules:
Do
Don’t
Write phrase on paper
Screenshot or photograph it
Store in two secure physical locations
Save in email, Google Docs, or cloud notes
Memorize if possible
Share with “support” agents
Verify backup accuracy
Enter on any website or Google Form
Common scam vectors to recognize:
Fake Coinbase or Google login pages reached via ads
Browser extensions with names similar to “Coinbase Wallet”
Pop-ups claiming your wallet needs “verification” via recovery phrase
Social engineering on Discord, Telegram, or Twitter
Legitimate dapps will never ask for your 12-word phrase. If something requests it, close the tab immediately.
Understanding network fees:
Network fees (gas on Ethereum) are paid to validators whenever you send tokens, swap on a DEX, or interact with smart contracts. These fees fluctuate based on network congestion—busy periods mean higher costs.
To manage fees:
Use gas tracker tools (searchable via Google) to find lower-fee periods
Consider L2 networks like Base for significantly reduced costs
Set custom gas limits in the extension for applicable transactions (EIP-1559 support)
Troubleshooting and Common Questions
Dapp can’t detect the extension?
Refresh the page
Disable conflicting extensions (especially other wallets)
Ensure Coinbase Wallet is unlocked
Try incognito mode with only Coinbase Wallet enabled
Browser profile reset or Chrome reinstalled? Extension data may be wiped. Your recovery phrase is the only way to restore access on a new installation.
Using the wallet on multiple devices? You can import the same wallet to Chrome on different computers or to the mobile Coinbase Wallet app using the same 12-word phrase. However, anyone who obtains that phrase gains full control—so protect it accordingly.
Forgot your password? Passwords cannot be recovered by the support team. You must either remember the password or re-import the wallet using your recovery phrase.
Where to find updated help? Check the official coinbase website Help Center and the Chrome Web Store listing for current instructions, supported browsers, and security recommendations. Search via Google to ensure you’re reaching legitimate Coinbase resources.
Conclusion
The Coinbase Wallet extension transforms your browser into a secure gateway for decentralized apps, DeFi protocols, and NFT marketplaces. By understanding the installation process, properly backing up your recovery phrase, and following security best practices, you create a foundation for confident Web3 exploration.
Self-custody means full ownership—and full responsibility. You control your digital assets without intermediaries, but you also bear the risk if your recovery phrase is lost or compromised. Combining the wallet extension with secure browsing habits in Chrome creates a powerful setup for managing crypto, executing transactions, and connecting to the decentralized web.
As Ethereum L2 networks like Base continue to grow and network fees become more accessible, desktop Web3 access through tools like the Coinbase Wallet extension will only become more practical. Whether you’re investing in DeFi yields, building an NFT collection, or simply exploring what’s possible with blockchain technology, the extension provides the access you need—securely and conveniently from your browser.
Coinbase Wallet Extension FAQ
Managing your crypto through a browser extension offers a seamless way to interact with the decentralized web directly from your computer. This comprehensive FAQ covers everything you need to know about the Coinbase Wallet browser extension, from installation to security best practices.
Introduction to Coinbase Wallet Extension
The Coinbase Wallet extension is a self-custody browser extension that gives you complete control over your private keys and digital assets. Unlike a Coinbase.com account where the platform holds your funds, this non custodial wallet means you—and only you—are the owner of your crypto.
As of 2026, the extension supports Google Chrome, Brave, Microsoft Edge, and other Chromium-based browsers via the Chrome Web Store. It’s a completely separate product from the main Coinbase app and exchange platform.
The wallet extension lets users connect directly to decentralized apps, DeFi protocols, and NFT marketplaces without leaving their browser. Here’s what sets it apart from the Coinbase.com brokerage:
Self-custody model: You control your private keys and recovery phrase
Dapp connectivity: Connect to thousands of crypto apps across multiple blockchains
Multi-chain support: Access evm compatible networks including Ethereum, Polygon, Base, and BNB Chain, plus Solana
NFT and DeFi access: Trade tokens on DEXes, earn yield, and manage NFT collections
Hardware wallet integration: Connect a Ledger device for enhanced security
How to Install the Coinbase Wallet Extension
Getting started with the extension requires downloading it from the official Chrome Web Store. Following these steps ensures you install the authentic version and avoid malicious imitations.
Navigate to the Chrome Web Store and search for “Coinbase Wallet”
Verify the publisher is “Coinbase, Inc.” before proceeding
Click “Add to Chrome” and confirm the installation prompt
The extension icon will appear in your browser toolbar once complete
Pin the extension for easy access by clicking the puzzle piece icon and selecting the pin
The extension requests specific permissions to function properly:
View your public wallet address when you connect to sites
Request transaction signatures for blockchain interactions
The extension never shares your private key or recovery phrase with any site or dapp
Warning: Fake extensions exist. Always verify the publisher name shows “Coinbase, Inc.” and check that the extension has millions of users with positive reviews. You can also find the official link at coinbase.com/help.
Creating a New Wallet in the Extension
After installation, you can create a fresh wallet directly within the extension. This process generates your unique blockchain identity and the critical recovery phrase you’ll need to secure.
Click the extension icon and select “Create new wallet”
Accept the terms of service to proceed
Create a unique username or web3 handle for your wallet
The extension generates a 12-word Secret Recovery Phrase locally on your device
Write down each word in the exact order displayed—this is your master key to all funds
Confirm your recovery phrase by entering select words when prompted
Set a strong extension password (use a passphrase of 12+ characters for best security)
Your wallet is now ready to receive and send crypto
The 12-word recovery phrase is generated entirely on your device and is never transmitted to Coinbase servers. This means Coinbase cannot recover your phrase or reset your password if you lose access.
Recovery phrase best practices:
Write the phrase on paper—never take a screenshot or store it digitally
Store copies in two separate secure locations
Never share it with anyone, including people claiming to be support agents
Never type it into any website or send it via email or chat
Your extension password protects local access on your computer but does not protect on-chain funds if someone obtains your seed phrase.
Importing an Existing Wallet (General)
If you already have a self-custody wallet elsewhere, you can import it into the Coinbase Wallet extension using your 12-word recovery phrase. This works with wallets from MetaMask, Trust Wallet, Phantom, Solflare, and many others.
Key concepts to understand:
Portability of seed phrases: The same 12-word phrase works across compatible wallet providers
Non-portability of passwords: Your password from another wallet doesn’t transfer—only the recovery phrase
Assets stay on-chain: Importing doesn’t move funds; it gives the extension access to view and sign for the same blockchain address
Multiple wallets supported: You can import several wallets and switch between them using the account selector
The general import flow:
Click the extension icon and choose “I already have a wallet”
Select “Import recovery phrase”
Enter your 12 words in the correct order
Create a new username and set a local password
Your imported wallet is now accessible in the extension
Importing Specific Wallets (Phantom, Solflare, Trust Wallet & Others)
Each wallet provider stores the recovery phrase in slightly different locations. Here’s how to find and export your phrase from popular wallets before importing into the Coinbase Wallet extension.
Phantom Wallet:
Open the Phantom extension or mobile app
Navigate to Settings (gear icon)
Select “Show Secret Recovery Phrase”
Enter your Phantom password when prompted
Copy the 12 words securely and import into Coinbase Wallet extension
Solflare Wallet:
Click your avatar or account menu
Select “Export mnemonic” from security settings
Click “Show” to reveal your phrase
Copy the phrase securely and complete the import process
Trust Wallet:
Open Settings within the app
Navigate to Wallets and select your chosen wallet
Tap “Show Recovery Phrase”
Copy the 12-word phrase displayed
Import using the Coinbase Wallet extension’s import flow
MetaMask:
Open MetaMask and go to Settings
Select Security & Privacy
Click “Reveal Seed Phrase” and enter your password
Copy the phrase and import into Coinbase Wallet extension
Other wallets:
Look in your wallet’s Security, Backup, or Recovery settings
Locate the option to reveal or export your 12-word (or 24-word) phrase
Copy securely and use “I already have a wallet” in the extension
Connecting a Ledger Hardware Wallet
For enhanced security, you can connect a Ledger hardware wallet to the Coinbase Wallet extension. This keeps your private key on the physical device while still using the browser interface for dapp interactions.
Prerequisites:
Ledger Nano S Plus, Nano X, or compatible device
Latest Ledger firmware installed via Ledger Live
Ethereum app (and other chain apps) installed on your Ledger
“Blind signing” or “Contract data” enabled for dapp interactions
Connection steps:
Click the extension icon and select “Import existing wallet”
Choose “Connect Ledger wallet”
Plug in your Ledger device via USB
Unlock the device and open the Ethereum app
Approve the connection request on your Ledger screen
Label your accounts for easy identification
Private keys never leave the Ledger device. The extension sends signing requests that must be physically approved on your hardware wallet each time you make a transaction. This setup can coexist with software wallets already in your extension.
Funding Your Coinbase Wallet Extension
There are multiple ways to add funds to your wallet extension depending on where your crypto currently resides.
Funding methods:
Transfer directly from your Coinbase.com account using the built-in connection
Receive from any external wallet by sharing your address
Purchase crypto on Coinbase.com and send to your extension address
Supported assets include:
ETH and ERC-20 tokens on Ethereum
USDC, DAI, and other stablecoins across multiple networks
Base network native assets and tokens
Polygon, Arbitrum, and other EVM-compatible tokens
Wrapped Bitcoin (WBTC) for Bitcoin exposure on Ethereum
To view your wallet address:
Click the extension icon
Select your account or go to Assets
Click “Show wallet address” to display your address and QR code
Important: Network selection matters. Sending ETH on Ethereum mainnet requires an Ethereum address, while USDC on Base requires selecting the Base network. Sending tokens on the wrong network can result in permanent loss.
Transferring Crypto from Coinbase.com to Coinbase Wallet Extension
The extension offers a streamlined way to move funds from your Coinbase.com exchange account to your self-custody wallet.
Option 1: Connect and transfer within the extension
Click the “Buy (+)” button or “Connect my Coinbase account” option
Authorize the connection through the Coinbase OAuth flow
Select the asset and amount to transfer
Preview the transaction details and confirm
Funds arrive in your extension after blockchain confirmation
Option 2: Manual send from Coinbase.com
Sign in to Coinbase.com on the web
Click “Send/Receive” in the navigation
Paste your extension wallet address or scan the QR code
Select the asset, choose the network, and enter the amount
Review transaction details and click send
Blockchain network fees apply to these transfers since they’re on-chain transactions. Once funds leave Coinbase.com and arrive in your self-custody extension, Coinbase cannot reverse transactions or recover funds sent to incorrect addresses.
Receiving Crypto from Other Wallets (Trust Wallet, MetaMask & More)
Receiving funds from external wallets follows a simple pattern regardless of which wallet the sender uses.
Receiving flow:
Open Coinbase Wallet extension and display your address or QR code
In the sending wallet (Trust Wallet, MetaMask, Phantom, Ledger, etc.), select “Send”
Choose the correct network and asset type
Paste your Coinbase Wallet extension address or scan the QR code
Verify the first and last characters of the address match
Confirm the transaction in the sending wallet
Safety checks:
Always double-check the network matches (Ethereum to Ethereum, Base to Base)
Verify address characters before confirming
Start with a small test transaction for large transfers
Remember that blockchain transactions are final and irreversible once confirmed
This process works identically whether receiving from Trust Wallet, MetaMask, Phantom on EVM chains, hardware wallets like Ledger, or any other compatible wallet.
Using the Extension with Dapps, DeFi, and NFTs
The Coinbase Wallet extension serves as your gateway to the decentralized web. Websites detect the extension and allow you to connect your wallet for various interactions.
How connections work:
Visit a dapp or DeFi site
Click “Connect wallet” on the site
Select Coinbase Wallet from the provider list
Approve the connection request in your extension popup
The site can now view your public address and request transaction signatures
What dapps can and cannot access:
View your public address and token balances
Request signatures for transactions you approve
Never access your recovery phrase or private keys
Cannot sign transactions without your explicit approval
Common use cases:
DeFi lending: Supply assets to earn yield on platforms across supported networks
Decentralized exchanges: Swap tokens with aggregated quotes from over 75 DEXes
NFT marketplaces: Buy, sell, and mint digital collectibles
Gaming dapps: Connect to blockchain games and manage in-game assets
DAO voting: Participate in governance for decentralized organizations
Network switching happens within the extension based on dapp requirements. You might use Ethereum for one protocol and switch to Polygon or Base for another.
Understanding Network Fees and Gas
Every blockchain transaction requires network fees, commonly called gas on Ethereum and EVM-compatible networks. Understanding these fees helps you manage costs when using your wallet.
What are network fees?
Payments to validators or miners who process and confirm your transactions
Required for sending tokens, swapping on DEXes, minting NFTs, and interacting with smart contracts
Measured in the native currency of each chain (ETH on Ethereum, MATIC on Polygon, etc.)
Why fees fluctuate:
Network congestion increases costs during high-demand periods
Complex transactions (like smart contract interactions) cost more than simple transfers
Priority selection (slow/average/fast) affects how quickly your transaction confirms
Fee display in the extension:
The extension shows estimated fees before you confirm any transaction
You can often adjust priority settings where supported
Coinbase does not control or subsidize network fees on public blockchains
During peak congestion, fees on Ethereum mainnet can make small transactions uneconomical. Layer 2 networks like Base and Polygon typically offer significantly lower fees.
Security, Privacy, and Recovery Phrase Best Practices
Self custody means complete responsibility for your wallet security. The extension provides the tools, but protecting your assets depends entirely on your practices.
Core security principles:
Your 12-word recovery phrase is the only way to restore access if you lose your device
Anyone with your phrase has full control of your funds across all compatible wallets
Coinbase cannot recover lost phrases or reset forgotten passwords
Google and other browser vendors cannot access keys stored by the extension
Actionable security practices:
Back up your recovery phrase offline on paper or metal
Never take screenshots or store phrases in cloud services
Never share your phrase with anyone—Coinbase support will never ask for it
Use a unique, strong password for the extension
Enable your operating system’s screen lock and login protection
Keep your browser updated to the latest version
Avoid installing unknown browser extensions that could be malicious
Regularly review and revoke unused dapp connections
Troubleshooting Common Coinbase Wallet Extension Issues
Technical issues occasionally arise with browser extensions. Here are solutions to the most common problems users encounter.
Extension icon missing after update:
