Security model
Trezor Bridge implements a least-privilege connection model. When a wallet connects, Bridge asks for user permission and binds the session to that site or app — protecting you from silent connections. All commands that could leak secrets require explicit confirmation on the physical Trezor device. This dual-confirmation flow (software request + physical acceptance) is the cornerstone of secure key custody.
UX and reliability
Historically, hardware wallets faced friction from driver issues, browser compatibility, and ephemeral disconnects. Bridge solves these by offering a stable background process that modern apps can rely on. It handles device reconnection gracefully and offers clear prompts when action is required. For end users that means fewer interrupts and faster transactions.
Compatibility
Trezor Bridge works with the official Trezor Suite, many third-party wallets, and browser-based dapps that support WebUSB or a Bridge-backed API. Because the connection is local and permissioned, Bridge is compatible with privacy-centric workflows that avoid cloud custody.
Privacy and telemetry
The Bridge service is intentionally minimal: it does not send your transaction data or device fingerprints to remote servers. Updates and telemetry (if enabled) are limited to version checks and diagnostic signals — and can be disabled for users that require a fully air-gapped or closed environment.
