Trezor™ Bridge provides a standard, trusted pathway between local applications and your Trezor device. It abstracts device detection, session handshaking, and encrypted payload forwarding into a single service that runs silently on your machine. The result: consistent behavior across platforms and fewer chances for user error when pairing or sending transactions.
Bridge enforces boundaries — apps may request actions, but sensitive operations are always confirmed on the hardware device. This model preserves the foundational security promise of hardware wallets: private keys never leave the device. Bridge simply enables clear, auditable communication so that signing and verification can proceed smoothly and safely.
For developers, Bridge reduces fragmentation by exposing a stable local interface to interact with devices. Integrations become more predictable, and user flows are simpler to implement. For organizations, Bridge makes it easier to maintain consistent behavior across browser versions and operating systems.
