Overview
What is Trezor Suite?
Trezor Suite is the official desktop + web interface produced by SatoshiLabs for managing Trezor hardware wallets. It acts as the canonical UI for firmware updates, transaction signing, coin management, swaps, staking and portfolio tracking — while ensuring private keys never leave the device.
Target audience
This brief is aimed at engineers, auditors, and integrators who need a clear technical map: modular architecture, developer APIs (Connect), build and release mechanics, and security controls that affect deployment or integration decisions.
Architecture & developer surface
Monorepo & components (high level)
Trezor maintains a monorepo containing Suite desktop, Suite web, Suite mobile, and Connect integration modules. Developers interact primarily with @trezor/connect and the Suite API surface to orchestrate device calls, event flows, and firmware operations.
Integration patterns
- Use
trezor-connectfor programmatic signing and account access in third-party apps. - Employ the Suite web UI as a reference implementation for UX and security flows (popups, device pairing, passphrase handling).
- Leverage Suite's Guide and docs as canonical user-facing explanations when onboarding customers.
Security & operational notes
Threat model highlights
All sensitive operations (seed derivation, signing) occur on the hardware; Suite is a host-side orchestrator. Pay attention to firmware update verification, host-to-device IPC, and passphrase management choices when integrating into custodial or remote signing flows.
Best practices for advanced users
- Pin and verify firmware signatures before allowing automated updates.
- Enable and audit WebAuthn/biometric unlock only as a convenience layer — keep the device locked for high-value operations.
- Use View-only mode for monitoring without exposing device state.
