Coinbase wallet setup connect dapps and recovery guide

Coinbase Wallet Setup Linking to DApps and Securing Your Recovery Phrase
 Download the Coinbase Wallet app directly from the official Google Play Store or Apple App Store. Avoid third-party links to eliminate any risk of installing a fraudulent application. Once installed, open the app and tap “Create a new wallet.” You will be responsible for your own security from this moment forward. 
 The application generates a unique 12-word recovery phrase, also known as a seed phrase. Write these words down in the exact order presented on a physical piece of paper. This phrase is your master key. Never store it digitally–no screenshots, emails, or cloud notes. Anyone with these words gains complete control over your assets, and Coinbase cannot restore them for you. 
 After securing your phrase, you will confirm it by selecting the words in order. The wallet then creates your public address, a string of characters starting with “0x”. You can share this address to receive funds. For interacting with decentralized applications, locate the built-in browser icon within the app. This tool is designed for connecting to Web3 platforms securely. 
 When you visit a DApp like Uniswap or OpenSea, it will request a connection through a pop-up. Carefully review the connection request, checking which network and address the site wants to link to. You can approve or reject this. Each transaction you sign afterward requires explicit confirmation and pays a network gas fee, which varies based on Ethereum congestion. 
 If you need to restore your wallet on a new device, the process relies entirely on your paper backup. Install the app again, choose “I already have a wallet,” and enter your 12-word phrase precisely. A single misplaced word will lock you out permanently. This method also works for importing your wallet into other compatible software like MetaMask, giving you full control over your identity across different interfaces. 
Downloading and Installing the Coinbase Wallet Application
 Get the official Coinbase Wallet app only from your device’s trusted source: the Apple App Store for iOS or the Google Play Store for Android. Avoid third-party websites to eliminate security risks. 
 Open your app store and search for “Coinbase Wallet.” Verify the developer is “Coinbase, Inc.” before tapping install. The app is free, and the download typically completes in under a minute on a stable connection. 
 Once installed, open the application. You will see two clear options: “Create a new wallet” or “I already have a wallet.” Select “Create a new wallet” to begin setting up a new self-custody account. 
 The app will then generate your unique 12-word recovery phrase. Write these words down in the exact order presented on a physical piece of paper. Store this paper securely, as these words are the only way to restore your wallet and assets if your phone is lost. 
 After confirming you have saved the phrase, you will be asked to re-enter it. This step verifies your backup and completes the wallet creation. Your Coinbase Wallet is now ready to use, and you can proceed to fund it or connect to decentralized applications. 
Creating a New Self-Custody Wallet and Secret Recovery Phrase
 Download the Coinbase Wallet app only from the official Google Play Store or Apple App Store to avoid fraudulent copies. Open the app and tap “Create a new wallet.” 
 Coinbase Wallet will immediately generate your 12-word Secret Recovery Phrase. This phrase is the master key to your wallet and funds. The app shows it once; no one, including Coinbase, stores a copy. 

Do This
Avoid This

Write each word in the exact order on durable, non-digital material like a steel plate or paper.
Never store the phrase digitally: no screenshots, cloud notes, emails, or text files.

Keep your written phrase in multiple secure physical locations, like a safe or locked drawer.
Do not share the phrase with anyone. Legitimate support will never ask for it.

Verify your backup by accurately re-entering the words when the app prompts you.
Do not proceed without completing the verification step; an incorrect backup locks you out permanently.

 After verification, set a strong, unique 6-digit PIN or biometric lock (fingerprint/face ID) on the app itself. This PIN protects local access, but your Secret Recovery Phrase remains the only way to restore your wallet on a new device. 
 Your self-custody wallet is now active. You control the keys. Losing the phrase means losing access to all assets in this wallet with no recovery option. Treat it with the highest level of security. 
Importing an Existing Wallet Using a Seed Phrase
 Prepare your 12 or 24-word recovery phrase before you start. Have it ready on paper or stored securely offline; you will need to type it in during the process. 
 Open your Coinbase Wallet app and tap “I already have a wallet.” Select the option to restore using a recovery phrase. Type your words in the exact order, with a single space between each one. 
 Double-check for common typing errors: 

Ensure each word is spelled correctly.
Verify the word sequence matches your backup exactly.
Confirm you haven’t added any extra spaces at the start, end, or between words.

 The app will process your phrase. If you see an error, carefully re-enter everything. A single mistake will prevent access. Once confirmed, set a new, strong app lock for your device. 
 After import, your wallet balance and transaction history will appear. This process only restores on-chain assets; any saved settings or custom token lists from the old wallet must be reconfigured manually. 
 Test the restoration by sending a small transaction. This confirms you have full control and that the import was successful before managing larger amounts. 
Connecting Your Wallet to a Decentralized Application
 Open the dapp you want to use in your mobile or desktop browser. Look for a clear button labeled “Connect Wallet” or a similar call to action on the dapp’s main page. 
 Select “Coinbase Wallet” from the list of connection options. If you’re on a desktop computer, the dapp will show a QR code. Open your Coinbase Wallet mobile app, tap the scan icon, and point your camera at the QR code to establish the link. For a direct mobile connection, the dapp will prompt you to open the link directly in your Coinbase Wallet app. 
 A connection request will appear on your phone’s screen. This request details what the dapp is asking to access, typically your public wallet address. Always review this screen carefully. Confirm that the dapp’s name matches what you expect before approving. 
 After approving, you are connected. Your public address is now visible to the dapp, allowing you to interact with its smart contracts. Your private keys and seed phrase never leave your wallet. 
 Manage active connections in your Coinbase Wallet settings under “Connected Apps.” You can review and revoke permissions for any dapp here at any time. This is a good practice for maintaining control over your wallet’s access points. 
Approving Transactions and Managing DApp Permissions
 Always inspect the transaction details on the confirmation screen before you tap ‘Approve’. This screen shows the exact amount, the network fee (gas), and the recipient address. A mismatch here is a major red flag. 
 DApps often request permission to access your wallet address and view token balances. You can grant this connection safely. However, a request for ‘token spending approval’ needs careful attention. 
 There are two key permission types to understand: 

Connection: Allows the DApp to see your public address. You can revoke this anytime from your wallet’s connected apps list.
Token Allowance (Spending Approval): Authorizes a smart contract to move specific tokens from your wallet, like granting a swap router access to your USDC.

 To manage active spending approvals, use a blockchain explorer like Etherscan or a dedicated approval-checking tool. Connect your wallet to these services to see and revoke any allowances you no longer use. Set a calendar reminder to review these permissions monthly. 
 For maximum security, adopt these habits: 

Reject transactions requesting an ‘unlimited’ token allowance. Manually set a limit close to the swap amount.
After a one-time interaction with an unknown DApp, immediately disconnect from the ‘Connected Sites’ section in your wallet settings.
If a transaction fee seems abnormally high compared to the network’s current average, cancel and investigate.

 Your wallet will only sign transactions you initiate. No DApp can automatically withdraw assets without your explicit approval for each action. Stay alert, and you’ll interact with confidence. 
Recovering Your Wallet After Losing Access or Your Device
 Use your 12-word Secret Recovery Phrase immediately. This phrase is the only tool you need to regain access to your funds and transaction history on a new device. 
 Install the Coinbase Wallet app on your new phone or computer. Select “I already have a wallet” during the setup process. The app will then ask you to enter your Secret Recovery Phrase in the correct order. Type each word carefully, double-checking for spelling errors. 
 After entering the phrase, your complete wallet–including all assets, collectibles, and previous connections–will be restored. You will then need to re-establish connections to any decentralized applications. Visit the dapp’s website and initiate a connection through its interface; your wallet will prompt you to approve the link again. 
 If you stored your recovery phrase on a hardware wallet like a Ledger, connect it to the Coinbase Wallet app and follow the prompts to restore access using the physical device instead of typing the phrase. 
 Never share your Secret Recovery Phrase with anyone. Coinbase support will never ask for it. If you cannot locate your phrase, the wallet and its contents are permanently inaccessible, as Coinbase cannot retrieve it for you. 
FAQ:
I installed the Coinbase Wallet app. What’s the first thing I should do before moving any crypto into it?
 The absolute first step is to secure your recovery phrase. After installing the app, it will generate a unique 12-word secret recovery phrase. Write these words down in the exact order on a piece of paper. Do not save it on your phone or computer. This phrase is the only way to restore your wallet if you lose your device. Only after you have physically stored this phrase somewhere safe should you proceed to fund your wallet. Treat this paper like the key to your bank vault. 
How do I connect my Coinbase Wallet to a decentralized application (dapp) like Uniswap?
 Open the dapp in your phone’s web browser. Look for a “Connect Wallet” button. Tap it and select “Coinbase Wallet” from the list. This will trigger your wallet app to open and ask for permission to connect. You’ll see the dapp’s name and the permissions it requests. Review this and approve. For desktop use, open the dapp in a browser like Chrome. Click “Connect Wallet,” choose Coinbase Wallet extension Wallet, and a QR code will appear. Open your Coinbase Wallet mobile app, go to the Settings, and tap “Connect to Dapp.” Scan the QR code with your phone to link the two. 
My phone was lost. How do I get my wallet and funds back on a new device?
 Download the Coinbase Wallet app on your new device. On the welcome screen, choose “I already have a wallet.” You will be asked for your 12-word recovery phrase. Enter the words in the correct sequence. This process creates a new access point to your existing wallet on the blockchain. Your funds and transaction history will appear. Using your recovery phrase is the only method for recovery. If you did not save the phrase, the wallet and any funds within it cannot be retrieved by anyone, including Coinbase. 
Is there a difference between the Coinbase exchange app and the Coinbase Wallet app?
 Yes, they are different. The Coinbase exchange app is for buying, selling, and trading crypto on the Coinbase platform. Coinbase holds the keys to those assets. The Coinbase Wallet is a self-custody wallet where you control the private keys via your recovery phrase. It’s for storing your own crypto and interacting directly with dapps and DeFi protocols. You can connect the wallet to your exchange account to transfer funds between them, but they are separate products with different security models.
