Avoid third-party links to eliminate security risks. Once installed, open the app and select "Create a new wallet." You will generate a unique 12-word recovery phrase–this is your wallet's master key.<br><br><br>Write down each word in its exact order on paper. Store this paper separately from your devices. Confirm you have saved it correctly by entering the words when prompted. The app never stores this phrase, so your written copy is the only backup. Enable biometric authentication like Face ID or a strong device passcode immediately after setup for daily protection.<br><br><br>Connecting to a DApp is straightforward. Inside the wallet, tap the browser icon and navigate to the DApp's website. When you see a "Connect Wallet" prompt, select Coinbase Wallet. A connection request will appear in your app; review the permissions and confirm. You maintain control–each transaction requires your explicit approval, and you can disconnect the DApp anytime from your wallet's settings.<br><br><br>If you need a new phone, recover your wallet using your 12-word phrase. Install the Coinbase Wallet app on the new device and choose "I already have a wallet." Enter your recovery phrase precisely. This process restores all your assets and transaction history because the blockchain records everything linked to those words. Never share your phrase digitally; legitimate support will never ask for it.<br><br>Downloading and Installing the Coinbase Wallet App<br><br>Get the Coinbase Wallet app only from official sources to protect your funds. Visit the Apple App Store for iOS devices or the Google Play Store for Android. Search for "Coinbase Wallet" and verify the developer is listed as "Coinbase, Inc." before downloading.<br><br><br>After installation, open the app and select Create a new wallet. You will see a 12-word recovery phrase, which is the master key to your wallet and assets. Write these words down on paper in the exact order shown. Store this paper securely, as anyone with these words can control your funds. The app will ask you to confirm the phrase by selecting the words in sequence–this step ensures you recorded it correctly.<br><br><br>Following this, set a strong 6-digit PIN or use your device's biometric security like Face ID or Touch ID. This local security protects access to the app on your specific device, but it does not replace your recovery phrase.<br><br><br>Your wallet is now active. Before connecting to dapps, take a moment to explore the main interface. You can tap the Receive button to find your public wallet address or use the Buy feature to fund your wallet with cryptocurrency. Having a small balance helps when you begin interacting with decentralized applications, as you'll need crypto for transaction fees.<br><br>Creating a New Self-Custody Wallet and Seed Phrase<br><br>Download the Coinbase Wallet app only from the official Apple App Store or Google Play Store to avoid fake applications.<br><br><br>Open the app and select "Create a new wallet." The software will generate a unique 12-word recovery phrase, which is the master key to your funds and identity on the blockchain.<br><br><br>Write each word in its exact order on the provided paper backup sheet or a durable material like metal. Never save this phrase digitally–avoid screenshots, email, or cloud notes, as these are vulnerable to hacking.<br><br><br>Confirm your backup by accurately re-entering the words when prompted. This step ensures you have recorded the phrase correctly and locks it in your memory.<br><br><br>Your self-custody wallet is now active. The seed phrase is non-negotiable; losing it means permanent loss of access to all assets in this wallet, as Coinbase cannot recover it for you.<br><br><br>Store your physical backup in a secure, private location, separate from your daily devices, like a safe or locked drawer.<br><br>Importing an Existing Wallet Using a Recovery Phrase<br><br>Open your Coinbase Wallet app and select "I already have a wallet." You will then choose the option to restore with a recovery phrase.<br><br><br>Enter your 12-word recovery phrase exactly as you recorded it. Follow these rules for accuracy:<br><br><br>Type each word in the correct sequence, from word 1 to word 12.<br>Place a single space between each word; do not use commas.<br>Double-check the spelling of every word.<br><br><br>The app will process the phrase. If you see an error, verify the words against your backup. A single mistyped word will prevent access. Once confirmed, you will be prompted to set a new, secure biometric lock or PIN for this device.<br><br><br>After regaining access, your assets and transaction history will reappear. This process only restores the on-chain information; you must manually reconnect to any dApps by revisiting their websites and approving the connection through your wallet interface again.<br><br><br>Store your recovery phrase more securely this time. Write it on a material that resists fire and water, or use a certified metal backup tool. Never store this phrase in digital formats like screenshots, cloud notes, or email.<br><br>Finding and Connecting to a Decentralized Application (DApp)<br><br>Open your Coinbase Wallet mobile app and tap the Browser tab or the Discover icon (a compass) to access a curated list of applications.<br><br><br>For a wider selection, visit a DApp aggregator like DappRadar or State of the Dapps directly from your wallet's browser. These sites rank applications by user activity, allowing you to filter by blockchain network such as Ethereum, Polygon, or Arbitrum.<br><br><br>Once you select a DApp, your wallet will typically prompt you to connect. Tap the "Connect Wallet" button on the DApp's site, then choose "Coinbase Wallet" from the list of options. A connection request will appear in your app–review it carefully and approve to establish the link.<br><br><br>Pay close attention to the network. If a DApp operates on Polygon but your wallet is set to Ethereum, transactions will fail. You can change networks within the DApp's interface or directly in your wallet's settings before connecting.<br><br><br>Your first interaction with a new DApp, like swapping tokens or minting an NFT, will require a separate permission to access your funds. This transaction needs your explicit approval and will show the estimated gas fee. Always verify the contract details and the total cost before confirming.<br><br><br>To manage your connections, go to your Coinbase Wallet settings and find "Connected Sites." Here you can review and revoke any DApp's access at any time, which stops it from initiating new transactions but does not reverse previously granted allowances.<br><br>Understanding and Confirming Transaction Requests from DApps<br><br>Always read the transaction pop-up in your Coinbase Wallet completely before approving. This screen contains the critical details of the operation the DApp wants to perform.<br><br><br>Focus on three specific data points: the contract address, the function being called, and the maximum gas fee. Verify that the contract address matches the DApp you intend to interact with. A mismatch is a strong sign of a phishing attempt.<br><br><br>Check the requested network. A DApp on the Ethereum mainnet should not ask for a transaction on Polygon or Arbitrum unless you specifically switched networks. Confirm you are on the correct blockchain to avoid losing funds.<br><br><br>Scrutinize the token amount and recipient address. Some malicious sites can pre-fill these fields. Ensure you are sending the exact amount to the exact address you expect. For swaps, check the minimum received amount to prevent excessive slippage.<br><br><br>Use the "Advanced Details" or similar option to view the raw data of the transaction. While encoded, this data shows the exact function call. If anything looks unfamiliar or too complex, reject the request and seek clarification from the DApp's official community channels.<br><br><br>Set custom spending limits for token approvals instead of approving unlimited amounts. This limits potential damage if a contract is compromised. You can manage and revoke existing approvals using tools like Etherscan's Token Approval Checker.<br><br><br>If a transaction seems suspicious, reject it immediately. A legitimate DApp will never pressure you to approve a request you do not understand. Your security is more important than completing any single transaction.<br><br>Managing Connected Sites and Revoking Permissions<br><br>Regularly review the list of applications with access to your wallet. Open your Coinbase Wallet app, go to Settings, and select 'Connected Sites'. You will see a complete list of every decentralized application currently authorized.<br><br><br>Each connection grants specific permissions, like viewing your wallet address or initiating transactions. Think of these as keys you've handed out; it's wise to collect them from places you no longer visit.<br><br><br>ActionReason to Take ItHow It Protects You<br>Revoke unused app permissionsThe app's security may have changed, or you might not use it anymore.Removes a potential path for unauthorized transactions from an old, forgotten connection.<br>Check permissions after a phishing scareIf you accidentally approved a malicious site, it could still have access.Immediately cutting off access prevents the site from draining assets later.<br>Audit connections monthlyMaintain a clean and secure access list as part of your routine.Proactive management reduces your attack surface and keeps you aware of active links.<br><br><br>To remove access, simply tap on a site's name in your 'Connected Sites' list. Select 'Disconnect' or 'Revoke Permission'. This action is immediate and does not require a blockchain transaction or a gas fee.<br><br><br>After revoking, the application will need to request a fresh connection the next time you visit. You will have to approve a new transaction to grant permissions again. This process ensures you maintain full control over which services interact with your funds at all times.<br><br>Restoring Wallet Access if You Lose Your Device<br><br>Your recovery phrase is the only tool you need to regain access. Keep your 12-word seed phrase secure and offline; it is the master key to your wallet on any new device.<br><br><br>Download the official Coinbase Wallet app on a new phone or computer. Select "I already have a wallet" during the initial setup. The app will then ask you to enter your secret recovery phrase. Type the words in the exact order you saved them, paying close attention to spelling.<br><br><br>After entering the phrase, your complete wallet–including all assets, accounts, and transaction history–will be restored. This process works because your funds live on the blockchain, not on the lost device itself. The wallet app is just a window to view and manage them.<br><br><br>Once restored, immediately set a new, strong password and biometric lock on the new device for added security. Treat your restored wallet as a reminder to confirm your recovery phrase is stored safely, like on a metal backup plate kept in a secure location. Never share these words digitally.<br><br><br>If you used the wallet with specific dApps, you may need to reconnect. Visit the dApp's website from the wallet's browser and approve the connection request. Your account addresses and permissions will be recognized once the link is re-established.<br><br>FAQ:<br>I installed the Coinbase Wallet app. What's the first thing I should do before adding any crypto?<br><br>The absolute first step is to securely back up your recovery phrase. During setup, the wallet will generate a 12-word secret phrase. Write these words down in the exact order on a physical piece of paper. Do not save a screenshot, email it, or store it digitally. This phrase is the only way to restore your wallet if you lose your phone or forget your password. Only after you have confirmed that your paper backup is safe and stored in a secure location should you proceed to fund your wallet or connect to apps.<br><br>How do I actually connect my Coinbase Wallet to a website like OpenSea or Uniswap?<br><br>You typically connect through your wallet's built-in browser for the safest experience. Open the Coinbase Wallet mobile app and tap the browser icon. Navigate to the dapp's website (e.g., app.uniswap.org). The site will usually detect your wallet and prompt you to connect. Tap "Connect" or "Connect Wallet" and select Coinbase Wallet from the options. You may need to confirm the connection in your wallet app. For desktop browsers, you can use the Coinbase Wallet extension. Click its icon in your browser toolbar, scan the QR code displayed on the dapp's site with your mobile wallet, and approve the connection.<br><br>I got a new phone. How do I get my wallet and all my assets back?<br><br>You need your 12-word recovery phrase from your initial setup. Install the [https://extension-start.io/coinbase-wallet.php Coinbase Wallet recovery phrase] Wallet app on your new device. Instead of creating a new wallet, select the option to "Restore" or "Import existing wallet." You will be asked to enter your 12-word phrase in the correct sequence. After entering it, your complete wallet—including all your cryptocurrencies, NFTs, and transaction history—will be restored. Your funds are not stored on the old phone; they are on the blockchain. The recovery phrase gives you control over that blockchain address on any new device.<br><br>Is it safe to connect my wallet to any dapp I find?<br><br>No, you should be selective. Connecting your wallet grants the dapp certain permissions, which could include access to view your wallet address and, in some cases, the ability to interact with your tokens. Only connect to well-known, reputable dapps. Check the website URL carefully to avoid phishing sites. Before confirming a transaction, review the details the wallet shows you—this shows what the dapp is asking to do. You can also revoke connections later in your wallet's settings under "Connected Apps." Treat connection requests with the same caution as handing out a key to your bank vault.<br>
