How to sync my Trust Wallet with the browser extension?

Understanding Trust Wallet and Browser Extension Integration

Trust Wallet is a popular non-custodial cryptocurrency wallet that supports a wide range of blockchain assets. While the mobile app serves as the primary interface, users often seek ways to interact with decentralized applications (dApps) on desktop browsers. The Trust Wallet browser extension bridges this gap by enabling seamless connectivity between the mobile app and web-based platforms.

This integration allows users to sign transactions, access DeFi protocols, and manage digital assets directly from their browser while maintaining the security of the mobile wallet. The process does not involve syncing data in the traditional sense but rather establishing a secure communication channel between devices.

Steps to Connect Trust Wallet Mobile App with Browser Extension

1. Install the official Trust Wallet browser extension from your browser’s web store. Ensure it is published by Trust Wallet to avoid phishing attempts.
2. Open the extension and select the option to connect a wallet. A QR code will appear on the screen.
3. Launch the Trust Wallet mobile application and navigate to the “Browser” or “Connect to Wallet” section, depending on your app version.
4. Use the built-in scanner in the app to scan the QR code displayed in the browser extension.
5. Confirm the connection request on your mobile device. Once approved, the extension will reflect an active connection.

Data Flow and Security Considerations

1. The connection operates through encrypted peer-to-peer messaging. No private keys are transmitted during the linking process.
2. All transaction signing occurs exclusively on the mobile device. The browser extension only relays requests and receives signed responses.
3. Users retain full control over their funds at all times, as the mobile app acts as the authorization layer for every action initiated via the browser.
4. If the mobile device is locked or the app is closed during a transaction prompt, the request will time out, preventing unauthorized execution.
5. Disconnecting the session from either end terminates the link immediately, ensuring no persistent access remains open.

Managing Connected Sessions and Troubleshooting

1. In the Trust Wallet mobile app, users can view active connections under the browser settings menu and manually disconnect any session.
2. If the QR code fails to generate, refresh the extension page and ensure both devices are connected to stable internet networks.
3. Clearing browser cache or reinstalling the extension may resolve persistent connectivity issues.
4. Never share the QR code with anyone, as it grants temporary access to initiate transactions requiring your approval.
5. Updating both the mobile app and browser extension to the latest versions ensures compatibility and access to recent security patches.

Frequently Asked Questions

Can I use multiple devices to connect to the same browser extension?No, each session requires a unique QR code scan from one mobile device. Simultaneous connections from different phones to the same extension are not supported.

Is my seed phrase ever exposed when connecting to the browser extension?Absolutely not. The seed phrase never leaves the mobile device. The connection uses cryptographic signatures without exposing recovery phrases or private keys.

What happens if I lose my phone after connecting to a dApp?The connection becomes inactive once the mobile app is inaccessible. Since transaction approvals require physical access to the device, no further actions can be authorized.

Does the browser extension store my transaction history?The extension does not store transaction data locally. All records remain within the mobile app, where they are encrypted and secured by the user’s device passcode.
