How to connect Coinbase Wallet to Uniswap? (DApp interaction)

Prerequisites for Wallet Connection

1. Ensure Coinbase Wallet mobile app is installed and updated to the latest version on iOS or Android.

2. Create or restore a wallet within the app using a valid 12-word recovery phrase.

3. Confirm that the wallet contains sufficient ETH or the native token required for gas fees on the target network.

4. Verify network settings inside Coinbase Wallet match Uniswap’s supported chains—Ethereum Mainnet, Arbitrum One, Optimism, Base, or Polygon.

5. Disable any third-party browser extensions that may interfere with DApp detection, especially if attempting connection via desktop browsers with WalletConnect.

Connecting via Mobile Browser

1. Open Safari (iOS) or Chrome (Android) and navigate to app.uniswap.org.

2. Tap the wallet icon in the top-right corner of the interface.

3. Select Coinbase Wallet from the list of available options.

4. Approve the connection request when prompted inside the Coinbase Wallet app.

5. Wait for the status indicator to change from “Connecting” to “Connected”, confirming successful session initialization.

Connecting via WalletConnect Protocol

1. Launch Coinbase Wallet and go to the “DApps” tab at the bottom navigation bar.

2. Tap the search bar and enter Uniswap, then select the official result.

3. The app will automatically initiate a WalletConnect v2 session with app.uniswap.org.

4. Review the permissions requested—including address exposure and transaction signing—and tap Approve.

5. Return to the Uniswap interface; your wallet address should now appear in the top-right corner.

Transaction Signing and Approval Flow

1. After selecting a token pair and entering trade parameters, click Swap.

2. A confirmation modal appears showing estimated gas, slippage tolerance, and price impact.

3. Tap Confirm Swap to trigger a signature request inside Coinbase Wallet.

4. Review the exact transaction details including recipient address, value, and data field before approving.

5. Once signed, the transaction propagates to the blockchain; status updates appear in real time on Uniswap’s interface.

Frequently Asked Questions

Q: Why does Uniswap show “Wallet not detected” even after opening Coinbase Wallet?A: This occurs when the mobile browser fails to detect the wallet’s deep link handler. Try refreshing the page, restarting the browser, or using the DApps tab inside Coinbase Wallet instead of external navigation.

Q: Can I connect Coinbase Wallet to Uniswap on desktop?A: Yes, but only through WalletConnect. Desktop browsers do not support Coinbase Wallet’s direct injection like MetaMask. Scan the QR code displayed on uniswap.org using the Wallet app’s scanner.

Q: Is it safe to approve Uniswap’s permission request for my wallet address?A: Yes. Address exposure alone does not grant access to funds. Uniswap cannot move assets without your explicit signature on each transaction.

Q: Why does my balance not update immediately after swapping?A: Balances refresh based on blockchain confirmations. Delays may occur during network congestion or if the selected RPC endpoint experiences latency. Manually refreshing the page often resolves display inconsistencies.
