Secure Crypto Connectivity Redefined
Trézór Bridge®™ is the foundational communication layer connecting your hardware wallet to the decentralized web with cryptographic certainty, eliminating reliance on vulnerable browser extensions.
The Secure Gateway to Web3
Trézór Bridge®™ is not just another utility; it is a critical security upgrade for the entire hardware wallet ecosystem. It operates as a tiny, persistent service on your computer, establishing a dedicated, encrypted communication tunnel between your connected hardware device and the web interface you are using (like Trezor Suite or a third-party dApp). Prior to the Bridge, secure interactions were often hampered by inconsistent browser extension support and inherent risks. This modern architecture ensures that every transaction is seamlessly signed on-device, isolating the critical cryptographic operations from the potentially vulnerable web environment. This design commitment to **local-first, secure transport** delivers unparalleled reliability and peace of mind for every crypto interaction, from simple balance checks to complex DeFi approvals.
Isolated Key Custody
The Bridge strictly adheres to a non-custodial design. Your private keys are generated and stored exclusively within the secure chip of your hardware wallet. The software utility never accesses, stores, or transmits your seed phrase or signing keys, ensuring the root of your digital security remains air-gapped from the host computer and the internet.
Zero-Config Firewall
Operating exclusively on the `localhost` interface (a private loopback connection), Trézór Bridge®™ ensures that sensitive communication data never leaves your computer for the external network. This intrinsic zero-configuration security model prevents remote interception and protects against common network-based vulnerabilities, offering a silent, robust layer of defense.
Cross-Platform Stability
Engineered for reliability, the Bridge offers unified performance across all major desktop environments—Windows, macOS, and various Linux distributions. This eliminates frustrating compatibility issues and ensures a consistent, high-speed connection, regardless of the user's operating system or preferred web browser for managing assets.
Open-Source Transparency
Trust is earned through verification. The source code for Trézór Bridge®™ is fully open-source and auditable by the global security community. This commitment to transparency allows for continuous peer review, guaranteeing that the utility operates exactly as advertised—securely and without any hidden backdoors or vulnerabilities.
Uncompromising Cryptographic Integrity
Trézór Bridge®™'s security architecture is built on layered defenses, surpassing the rudimentary protections offered by outdated methods. The process begins with a cryptographic handshake between the Bridge service and the hardware wallet firmware, establishing a chain of trust. End-to-end communication is secured using advanced, post-quantum resilient standards, ensuring data privacy and integrity. Furthermore, the Bridge automatically validates the authenticity and version of the hardware firmware and the connecting web application, neutralizing potential risks from rogue scripts or outdated protocols before any transaction data is processed. This systematic approach to validation and isolation makes it the gold standard for secure, auditable crypto operations, setting a new benchmark for device-to-web connectivity in a decentralized world.
Security Pillars
- 1.
Cryptographic Handshake: Device and Bridge authenticate each other before any data exchange using elliptic curve cryptography for secure session establishment.
- 2.
On-Device Verification: Final confirmation of the transaction (recipient address, amount, fees) is always displayed and approved on the uncompromisable screen of the physical device.
- 3.
Anti-Malware Design: The narrow scope of the Bridge (transport only) and its local-host restriction significantly reduce the attack surface, making it resistant to remote malware exploitation.
