How do I manage DApp connection permissions in Coinbase Wallet?

Understanding DApp Connection Permissions

1. When interacting with decentralized applications, users must grant access to their wallet data. This includes public addresses and blockchain activity. Coinbase Wallet ensures that private keys never leave the user’s device, maintaining control over assets at all times.

2. Each time a DApp requests connection, a prompt appears within the Coinbase Wallet interface. Users can review the scope of requested permissions before approving or denying access. The application cannot execute transactions without explicit approval.

3. Connected DApps are listed in the browser section of the wallet. From there, users can disconnect at any time. Disconnecting removes the DApp's ability to view wallet information or initiate transaction requests.

4. Some DApps may request additional permissions for specific functions like token approvals or smart contract interactions. These require separate confirmations beyond initial connection authorization.

Steps to Approve or Deny Access

1. Open the dapp browser in Coinbase Wallet and navigate to the desired decentralized application. Upon detecting a wallet connection request, the app triggers a secure notification.

2. A modal window displays the name of the DApp and details about what information it wants to access. Users should verify the URL matches the legitimate site to avoid phishing attempts.

3. Choose “Connect” to allow the DApp to view the public address and network status. Selecting “Cancel” denies access entirely, preventing further interaction unless re-initiated by the user.

4. After connection, transaction prompts will originate from within the wallet itself. No action occurs on-chain until the user manually confirms each operation through biometric or passcode authentication.

Managing Active Connections

1. Navigate to the 'Browser' tab and tap the menu icon to reveal active sessions. A list of currently connected DApps appears with options to inspect or terminate links.

2. Tap any entry to see recent interaction history and associated networks. This transparency allows users to identify unusual behavior or unfamiliar services.

3. To revoke access, select “Disconnect.” This immediately cuts communication between the DApp and wallet. Future visits to the same site will require a new connection request.

4. Regular audits of connected services help maintain security hygiene. Removing unused or untrusted DApps reduces exposure to potential exploits even if those platforms remain operational.

Security Best Practices for DApp Usage

1. Only connect to well-known and audited decentralized applications. Research community feedback and check for verified contracts before granting access.

2. Avoid entering sensitive personal information into DApp interfaces. Legitimate blockchain applications do not require identity documents or off-chain credentials.

3. Enable two-factor authentication within Coinbase Wallet settings. While this does not protect against fraudulent DApp transactions, it adds a layer of defense against device-level breaches.

4. Monitor gas fees and contract interactions closely when signing transactions. Malicious sites may attempt to trick users into approving high-cost operations or unauthorized token transfers.

Frequently Asked Questions

What happens when I disconnect a DApp?Disconnecting revokes its ability to detect your wallet presence. It no longer sees your balance or address unless you reconnect manually. Any prior approvals, such as token allowances, remain active and must be canceled separately.

Can a DApp steal my funds after I connect?No direct theft occurs upon connection alone. Funds are only moved when you sign transactions. However, malicious DApps might trick users into signing harmful contract calls. Always verify transaction details before confirmation.

Why does a DApp ask for repeated connection requests?This may happen due to session expiration or cache resets. It could also indicate an unoptimized frontend. Reconnecting is safe as long as you recognize the domain and purpose of the service.

Are my NFTs visible to every connected DApp?Yes, once connected, a DApp can query your wallet’s holdings across supported standards like ERC-721 or ERC-1155. Visibility does not imply transfer rights—those require individual transaction authorizations.
