Coinbase wallet extension setup dapps recovery guide
Coinbase Wallet Extension Setup Dapps Access and Account Recovery Steps
Install the Coinbase Wallet extension directly from the Chrome Web Store to begin. This step ensures you get the authentic software, avoiding phishing risks. After adding the extension to your browser, launch it and select "Create a new wallet." The system will generate your unique 12-word recovery phrase.
Write down this secret phrase on paper and store it in a secure physical location. This phrase is the master key to your assets; the wallet extension cannot restore it for you. Confirm you have saved it correctly by entering the words in the requested order. Your wallet is now active and ready to connect to decentralized applications.
To use a DApp, navigate to its website and look for a "Connect Wallet" button. Click it, choose Coinbase Wallet from the list, and approve the connection request in the extension pop-up. This link allows the DApp to view your public address and interact with your funds based on your signed approvals, all while your private keys stay secure on your device.
If you need to restore your wallet on a new device, open the extension and pick "I already have a wallet." Enter your 12-word recovery phrase exactly as you recorded it. This process rebuilds your entire wallet profile, including your asset balances and transaction history, because the blockchain records all data linked to your address.
Installing the Coinbase Wallet Extension in Your Browser
Visit the official Chrome Web Store or Firefox Browser Add-ons site directly from your browser. Search for "Coinbase Wallet" and confirm the developer is listed as "Coinbase, Inc." to avoid fraudulent copies.
Click the "Add to Chrome" or "Add to Firefox" button on the extension's page. A dialog will appear requesting specific permissions; review these to understand what the extension needs to function, then confirm the installation. The extension icon will appear in your browser's toolbar once the process finishes.
Click the new Coinbase Wallet icon to launch the setup. You will see a clear choice: "Create a new wallet" or "I already have a wallet." Select the option that matches your situation. The extension will then guide you through securing your recovery phrase–a 12-word secret key you must write down and store offline.
Complete the setup by following the on-screen prompts to verify your recovery phrase. After this, choose a secure password for encrypting your wallet's local access on this browser. You can now connect to decentralized applications by clicking the wallet icon when visiting a supported dapp's website.
Creating a New Self-Custody Wallet from Scratch
Download the Coinbase Wallet extension only from the official Chrome Web Store. Click "Add to Chrome" and confirm the installation. A new browser tab will open automatically for setup.
Select "Create a new wallet". The software will generate a unique 12-word recovery phrase, also called a seed phrase. This phrase is the master key to all your assets and future account access.
Write each word down in the exact order presented on a durable material like metal, not on a digital device. Store this physical copy in a secure location. Proceed only after you've completed this step.
You'll verify the phrase next by selecting the words in the correct sequence. This confirms your backup. After verification, establish a strong, unique password for encrypting the wallet's local data on your browser.
Your new wallet is now active. The extension will display your public receiving address, a string of characters starting with "0x". Use this address to receive funds or connect to decentralized applications.
Before depositing significant assets, send a small test transaction to confirm you can receive funds. Then, explore a dapp by visiting its website and clicking the "Connect Wallet" button, selecting Coinbase Wallet from the list.
Your recovery phrase is non-negotiable. Coinbase cannot recover it for you. Anyone with these 12 words has complete control over the wallet and its contents.
Importing an Existing Wallet Using a Secret Recovery Phrase
Open the Coinbase Wallet extension and click "I already have a wallet." You will see a field to enter your Secret Recovery Phrase.
Enter your 12-word phrase exactly as you recorded it. Follow these specific steps for accuracy:
Type all words in lowercase letters.
Place a single space between each word–no commas or extra spaces.
Double-check the spelling of every word, especially ones that sound similar.
The system will process your phrase and restore your wallet. This action will give you access to all your existing assets and transaction history linked to that phrase.
After import, take a moment to verify your restored wallet address matches the one you expected. You can then immediately begin interacting with dApps; your wallet is ready.
If the import fails, carefully re-enter your phrase. Common issues include an incorrect word order, a misspelling, or an extra space. Having a physical backup of your phrase is necessary for this process.
Connecting the Extension to a Decentralized Application (DApp)
Look for a "Connect Wallet" button on the DApp's website; this is usually in the top-right corner.
Clicking it will typically show a list of wallet options. Select Coinbase Wallet from the menu. A pop-up notification from your browser extension will appear, asking you to confirm the connection.
Review the connection request details within the pop-up. Check the DApp's name and the permissions it requests, like viewing your wallet address. Confirm the action by clicking Connect or Approve in the extension window.
After approval, the DApp interface will update. You should see your public address displayed, confirming a successful link. The DApp can now read your address for transactions but cannot move funds without your specific signature for each action.
If the connection fails, ensure your Coinbase Wallet extension is unlocked. Refresh the DApp page and try the steps again. Some DApps require you to be on a specific network; verify your wallet's current network matches the DApp's requirement.
To manage connected sites later, open your extension, go to settings, and find the "Connected Apps" section. Here you can review and revoke any connection at any time.
Approving Transactions and Interacting with DApp Functions
Always check the network you're connected to before confirming any transaction. A DApp on Polygon won't work if your wallet is set to Ethereum Mainnet. Your Coinbase Wallet extension displays the current network in its interface.
When a DApp prompts a transaction, a detailed window appears. Review these three data points every time:
Field to Check
What It Means
Gas Fee (Network Fee)
This is the payment for processing the transaction. During network congestion, these fees can rise significantly.
Spending Cap
For token approvals, this is the maximum amount the DApp can withdraw. You can often lower this from "unlimited" to a specific sum you're comfortable with.
Contract Address
Verify that this address matches the official DApp contract. Scammers may try to use malicious look-alike contracts.
If a transaction seems stuck, you can speed it up. In your wallet's activity tab, find the pending transaction. The interface may offer an option to increase the gas fee, which helps prioritize it on the blockchain.
For functions like swaps or staking, you'll typically need to approve the DApp to use your tokens first, followed by a second transaction to execute the main action. This two-step process is standard for security. After granting approval, you can often execute the main action with a single click on the DApp's site.
Keep a small amount of the network's native cryptocurrency (like ETH for Ethereum) in your wallet. You need it to pay gas fees for every transaction, regardless of the tokens you're swapping or staking.
Finding Your Secret Recovery Phrase for Backup
Open your Coinbase Wallet extension and click the settings icon (gear symbol) in the top-right corner.
Select "Security & Privacy" from the menu, then choose "Show Secret Recovery Phrase." You will need to re-enter your password for verification.
The extension will display your unique 12-word phrase. Write each word down in the exact order it appears, using correct spelling.
Use the provided pen-and-paper icon to copy the entire phrase at once, minimizing the risk of manual error. Paste it only into a secure, offline document if you are creating a digital backup on an air-gapped device.
Never save this phrase in a plain text file, email, or cloud note that is connected to the internet. Physical paper stored in a safe place is the most secure method.
After confirming your backup is stored securely, click "I've Saved My Recovery Phrase" within the extension to complete the process.
Restoring Access if You Lose Your Password or Device
Your recovery phrase is the only way to regain access if you forget your password or lose your device. Write these 12 words down in the exact order they were given and store them securely offline.
To restore your wallet using the phrase:
Install the Coinbase Wallet extension on a new browser.
Click "I already have a wallet" on the setup screen.
Select "Recovery Phrase" and enter your 12-word phrase when prompted.
Create a new, strong password for this installation. This password is specific to the device and browser you are using.
If you only lost your password but still have your original device, you can reset it from within the extension's settings. You will need your recovery phrase to complete this reset and set a new password.
Without your recovery phrase, you cannot restore your wallet. Coinbase cannot retrieve it for you. For added security, consider using a hardware wallet, which requires physical confirmation for transactions, paired with your Coinbase Wallet extension.
After restoring access, reconnect to your decentralized applications. Visit the dApp's website and select Coinbase Wallet recovery phrase Wallet when prompted to connect. Your wallet address and assets will reappear.
Q&A:
I installed the Coinbase Wallet extension but can't see my existing wallet. How do I recover it?
To recover an existing wallet in the Coinbase Wallet extension, you need your 12-word recovery phrase (seed phrase). Open the extension and click "I already have a wallet." You will be prompted to enter your secret recovery phrase. Type the words in the exact order, with a single space between each word. Ensure you are entering the phrase in a private setting and on the official Chrome Web Store extension. After submitting, your wallet, assets, and transaction history will be restored.
After setting up the extension, how do I actually connect to a dapp?
First, visit the website of the decentralized application (dapp) you want to use. Look for a "Connect Wallet" button, usually in the top corner. Click it, and a menu will show different wallet options. Select "Coinbase Wallet" from the list. Your browser extension should then trigger a pop-up asking you to confirm the connection. Review the permissions the dapp is requesting and click "Connect" or "Approve." The dapp's interface will now show your wallet address and allow you to interact with its features.
Is my recovery phrase stored anywhere in the browser after I enter it?
No. When you enter your 12-word recovery phrase during the setup or recovery process, it is processed locally on your device to regain access to your wallet. The phrase itself is not stored by the browser extension, on Coinbase's servers, or in your browser's history or cache. This is why you must write it down and keep it secure. If you clear your browser data or use a new computer, you will need the physical copy of your phrase to access your wallet again.
I connected to a dapp and now I want to revoke its access. How?
You can manage dapp permissions directly in the Coinbase Wallet extension. Open the extension and click the settings icon (gear symbol). Go to "Connected Sites" or a similar menu. You will see a list of all dapps currently connected to your wallet. Find the one you want to disconnect and click "Disconnect" or "Revoke Permission." This action stops the dapp from initiating new transactions but does not reverse any already-approved contracts. For full security, you may also need to revoke specific token allowances using a dedicated dapp like revoke.cash.
What happens if I uninstall the extension? Will I lose my crypto?
Uninstalling the extension only removes the access point from that specific browser. Your crypto assets remain secure on the blockchain. However, you will lose local access. To regain access, you must reinstall the Coinbase Wallet extension and go through the recovery process using your original 12-word recovery phrase. Without this phrase, you cannot restore your wallet and the assets within it become permanently inaccessible. Always confirm your recovery phrase works before uninstalling any wallet software.
I installed the Coinbase Wallet extension, but my existing wallet isn't showing up. How do I recover it using my secret recovery phrase?
If your wallet isn't appearing after installing the extension, you need to restore it manually. Open the extension and click "I already have a wallet." You'll be prompted to enter your 12-word secret recovery phrase. Type the words in the exact order, with a single space between each word. Be careful with spelling. After entering the phrase, you will be asked to create a new password for the extension. This password encrypts your wallet data on this browser. Once completed, your full wallet balance and transaction history should load. The recovery phrase is the only way to restore your wallet on a new device, so its security is critical.
After recovering my wallet in the extension, some of my tokens aren't visible or a dApp says I'm on the wrong network. What should I do?
This is a common issue. First, check the selected network. The extension defaults to the Ethereum Mainnet. Click the network name at the top. If your tokens are on a different chain, like Polygon or Arbitrum, you must manually add that network or switch to it if already listed. For missing tokens, you may need to add the token contract manually. Go to the 'Assets' tab and click 'Import token'. Find the correct contract address for your token from a reliable source like the project's official site or a blockchain explorer. Paste it, and the token symbol and balance should appear. For dApp connectivity, ensure the dApp's website is open and you've selected the matching network in your wallet before clicking 'Connect'.
