Trezor Bridge® is the dedicated communication service developed by Trezor to ensure seamless and secure interaction between Trezor hardware wallets and supported web interfaces. It operates silently in the background, acting as a reliable connector between your device and your browser without exposing private data or compromising security.
Designed to replace outdated browser plug-ins, Trezor Bridge delivers a modern, stable, and encrypted communication channel. It enables your hardware wallet to function smoothly with compatible desktop browsers while preserving the core principle of hardware-based security: your private keys never leave the device.
Trezor Bridge was created to solve a critical technical limitation. Modern browsers restrict direct communication with external USB devices for security reasons. Without a secure intermediary, a browser cannot directly interact with a hardware wallet. Trezor Bridge fills that gap.
Installed locally on your computer, it runs as a lightweight background service. When you connect your Trezor device via USB, Bridge detects the device and establishes a secure session between your browser and the hardware wallet. All requests—such as transaction approvals, address confirmations, and firmware checks—are transmitted through this protected channel.
Communication remains encrypted and verified
No private keys are transmitted outside the hardware wallet
Browser compatibility remains consistent across updates
This structure guarantees operational reliability while maintaining the highest security standards.
Seamless Integration with Trezor Devices
Trezor Bridge supports both major hardware wallet models developed by Trezor:
Trezor Model One
Trezor Model T
Once installed, the software automatically recognizes connected devices and facilitates communication without requiring manual configuration. Users simply connect the device and access the supported web interface. The Bridge service handles the rest.
This automatic detection system minimizes friction and eliminates the need for browser extensions or complicated setup procedures. It ensures that firmware verification, transaction signing, and wallet management tasks are executed efficiently.
Security is the fundamental principle behind Trezor Bridge. Unlike software wallets that store private keys directly on a computer, Trezor hardware wallets keep cryptographic secrets isolated within the device’s secure environment. Bridge does not access, store, or process private keys.
Instead, it relays requests from the browser to the device and returns signed responses. Each transaction must be physically confirmed on the hardware wallet, ensuring user authorization at every critical step.
Additional security characteristics include:
Encrypted local communication
Strict device authentication
No remote data storage
Protection against browser-based vulnerabilities
Because Bridge operates locally, it reduces exposure to web-based threats. Even if a browser is compromised, sensitive data remains protected inside the hardware wallet.
Trezor Bridge is engineered for cross-platform compatibility. It supports major desktop operating systems and functions with widely used browsers that comply with modern security frameworks.
The service runs silently in the background using minimal system resources. It does not interfere with other applications, nor does it require constant user interaction. Updates are designed to maintain compatibility with browser security changes and firmware improvements.
Its lightweight design ensures fast response times when initiating transactions, checking balances, or confirming addresses. Users experience stable connectivity without repeated reconnection prompts.
Installing Trezor Bridge is straightforward. Once downloaded and installed on a supported desktop system, the service activates automatically. No extensive configuration is required.
Connect the Trezor hardware wallet via USB.
Access the supported wallet interface in your browser.
Bridge detects the device and establishes secure communication.
From that point forward, the service operates transparently. When a transaction is initiated, the request travels through Bridge to the device. The user reviews and confirms the transaction on the hardware wallet screen. After confirmation, the signed transaction is returned securely through the same channel.
The process ensures that all critical actions remain under direct user control.
Earlier hardware wallet communication relied on browser extensions. However, browser ecosystems evolved, imposing stricter security policies that limited extension-based device access.
Trezor Bridge was introduced as a more reliable alternative. Unlike extensions that depend on browser-specific frameworks, Bridge operates independently as a local service. This separation enhances long-term compatibility and stability.
Greater reliability across browser updates
Improved security isolation
Reduced dependency on third-party extension ecosystems
By decoupling hardware communication from browser plug-ins, Trezor strengthened its infrastructure and ensured consistent performance.
Trezor Bridge does not collect personal data or transmit sensitive information to external servers. Its role is limited to enabling local communication between your browser and your hardware wallet.
All cryptographic operations are performed within the device itself. Bridge functions strictly as a communication relay, not as a data processor or storage service.
This approach reinforces user privacy and aligns with the broader philosophy of self-custody: you remain in full control of your digital assets at all times.
Regular updates to Trezor Bridge maintain compatibility with operating systems and browser security protocols. These updates are essential to ensure uninterrupted device communication and optimal protection.
When a new firmware version becomes available for your hardware wallet, Bridge ensures that communication during the update process remains secure and verified.
Maintaining the latest version of the Bridge service helps prevent connectivity issues and preserves the integrity of your wallet operations.
Trezor Bridge is built for stability in everyday use. Whether sending cryptocurrency, verifying receiving addresses, or managing multiple accounts, the service maintains a consistent communication link between device and browser.
Its background operation allows users to focus on wallet management without technical complexity. The integration remains transparent, secure, and efficient throughout all supported interactions.
Trezor Bridge® is an official communication service developed to support Trezor hardware wallets. Always download software from official sources and verify authenticity before installation. Cryptocurrency transactions are irreversible, and users are responsible for securing recovery seeds and device access credentials.
