Overview: This presentation explains what Trezor Bridge was, how Trezor Suite now manages device communication, and best practices for secure crypto custody and device usage.
Trezor Bridge was a small background program whose job was to let your computer and browser talk to a Trezor hardware wallet. It exposed a local endpoint that Trezor Suite and web apps could use to access the device, enabling signing, account discovery, and transaction flows without direct USB protocol handling in each app.
Important: the standalone Trezor Bridge has been deprecated — Trezor now recommends using Trezor Suite and its built-in mechanisms for device communication. If you have an old standalone Bridge installed, follow official guidance to remove it to avoid compatibility issues. :contentReference[oaicite:1]{index=1}
Trezor Suite is the official desktop & web application for managing Trezor devices. It centralizes setup, account management, transaction signing, portfolio tracking, staking and swaps — all while keeping private keys isolated on the hardware device. The Suite is the recommended entry point for most users. :contentReference[oaicite:2]{index=2}
Private keys and seed material are generated and stored only on the hardware device. Signing operations occur inside the device; only the signed transactions leave it.
Trezor designs its ecosystem to minimize trusted software: the hardware wallet, verified firmware, signed desktop/web apps, and a small set of backend services. Always prefer official downloads and verify signatures when possible. :contentReference[oaicite:3]{index=3}
Verify installers and check PGP signatures for desktop apps/releases; prefer official GitHub releases or the main website for downloads. This reduces the risk of tampered installers.
Use Trezor Suite for routine sends/receives. Confirm each transaction on the device screen, never just in the app. Treat the physical device and seed as the root of trust.
Keep Trezor Suite and your OS updated; remove deprecated helpers (like the old standalone Bridge) per official guidance to prevent conflicts. Use local verification steps for installers when available. :contentReference[oaicite:4]{index=4}
Developers who integrate Trezor functionality should use the maintained libraries and APIs (Trezor Connect and the Suite monorepo). Source code and releases are available on the official repositories for inspection and verification. :contentReference[oaicite:5]{index=5}
Advanced users can run a local blockbook backend to avoid reliance on remote indexing services, improving privacy and control. Official guides explain how to run these local instances safely.
Uninstall the standalone Bridge if instructed by the official deprecation notice. Use the most recent Suite release to manage device connections going forward; this avoids conflicts and preserves the best user experience. :contentReference[oaicite:6]{index=6}
Always download installers from trezor.io or the official GitHub organization and verify signatures as shown in the official guides. This is one of the simplest and most effective defenses against tampered software. :contentReference[oaicite:7]{index=7}
