Overview
Trezor Suite is the official software companion to Trezor hardware wallets. It provides a single, consistent interface you can run either as a native desktop application (Windows, macOS, Linux) or as a web application in your browser. The core design goal is simple: keep private keys and signing operations on the hardware device while offering a clean, modern interface for account management, portfolio tracking, transactions and device maintenance.
Whether you are new to hardware wallets or an advanced user managing multiple accounts, Suite aims to reduce complexity without compromising security. This document describes the Suite’s main features, recommended workflows, security best practices and developer-facing integration options.
Why Use Trezor Suite?
Hardware wallets protect your private keys from malware and exposure on general-purpose computers. Trezor Suite is the safe bridge between your device and the internet: it prepares transactions, fetches balance and transaction history data, and displays information in a verifiable way so you can confidently sign operations on the device itself. Key benefits include:
- Local signing: All sensitive signing always happens on your Trezor device — Suite never transmits or stores private keys.
- Clear transaction previews: Suite emphasizes human-readable transaction details; always verify on-device.
- Cross-platform: Install as a desktop app for a native experience or use the web app when you need convenience across multiple machines.
- Centralised management: View balances across cryptocurrencies, manage multiple accounts and keep a historical view of performance.
Core Features
Device & Firmware Management
On first connection Suite guides you through device initialization: generating a recovery seed, setting a PIN and choosing whether to enable a passphrase. Routine firmware updates are delivered through Suite; each update is cryptographically signed and the Suite verifies the authenticity before flashing the device.
Account and Portfolio
Suite aggregates your supported coin balances into a consolidated portfolio view. It supports hierarchical deterministic accounts (HD wallets) for blockchains like Bitcoin, and account-based models such as Ethereum. You can filter and explore transaction histories, export CSVs for record-keeping, and track price performance across timeframes.
Construct, Preview & Sign Transactions
Prepare transactions inside Suite and always confirm the transaction details on the physical device screen. Suite supports advanced transaction options where available — custom fees, coin control for UTXO management, and multi-output transactions — while making final verification explicit and straightforward.
Exchange & Swap Integrations
For convenience, Suite may surface integrated swap or exchange partners so you can trade assets without leaving the interface. Trades are routed through third-party providers and executed off-device; only the transaction approval happens on the Trezor itself, keeping signing keys isolated.
Desktop vs Web — Practical Differences
Both versions provide the same security model and core functionality. The choice comes down to workflow and threat model:
- Desktop: Runs from a native application, can cache data locally, and is a good choice for users who prefer a dedicated environment or offline workflows for extra safety.
- Web App: Runs in the browser and is convenient for quick access from multiple machines. The web app still requires the Trezor device for signing and never receives private keys.
If you frequently switch machines, the web app offers flexibility. If you prioritise a hardened operation environment or minimising exposure to browser plugins or untrusted sites, a dedicated desktop install is recommended.
Security & Best Practices
Trezor’s security model separates the hardware (the device that stores private keys) from the host (the computer or browser running Suite). Observing a few core best practices will help keep assets secure:
- Never share your recovery seed: The 12/24-word recovery seed is the single backup for funds. Write it down on durable material and store copies in separate, secure locations. Suite will never ask for your seed during normal use.
- Use a device PIN: The PIN protects access to your device if it’s lost or stolen. Choose a PIN you can remember but that’s not trivially guessable.
- Consider a passphrase: An optional passphrase adds an additional secret that derives separate wallets from the same seed. Use it only if you understand the risk: loss of the passphrase is equivalent to loss of the funds it protects.
- Verify every transaction on-device: Displayed details on the computer can be manipulated by malware; the final human-readable confirmation on the device is the authoritative source.
- Keep firmware up to date: Firmware updates include security improvements and feature additions. Only apply updates offered through official Suite channels and verify signature prompts on the device.
Supported Coins, Tokens & Limitations
Trezor hardware wallets support a broad set of cryptocurrencies, including Bitcoin, Ethereum, and many other chains and tokens. Token support — especially for newer or experimental networks — may vary between Suite releases and device firmware versions. Some tokens require external explorers or integration with third-party wallets for full functionality. Always check the official supported-assets list before attempting to access less common networks.
Getting Started — Step-by-Step
- Install or open Suite: Download the desktop application from the official site or open the verified web app in a supported browser.
- Connect your Trezor: Plug in the device, follow the on-screen prompts and set a PIN if creating a new wallet.
- Generate or recover your seed: If this is a new device, create a recovery seed on-device and write it down. If you’re migrating, use the recovery option and enter your existing seed on the device, never into the computer.
- Add accounts: In Suite, add accounts for the coins you’ll use. Some networks may require additional steps or external integrations.
- Test with a small amount: Before sending large sums, send a small test transaction to confirm you understand the flow and verification steps.
Practical Tips & Trouble-shooting
- Confirm details shown on the device screen before approving — device confirmation is the final check against tampering.
- If Suite does not detect your device, try a different USB cable or port and confirm the device’s screen shows the connection prompt.
- Keep an offline copy of your recovery seed — never store it in cloud storage or on an internet-connected device.
- For high-value holdings, consider splitting funds across multiple seeds or devices and use multisignature setups where appropriate.
Developer Integrations & APIs
Developers can integrate Trezor into their applications using officially supported libraries and standard protocols. Typical integrations include transaction signing, account discovery and message signing for authentication flows. When building integrations, always design for clear user prompts and require explicit on-device confirmation for sensitive operations. Direct users to official documentation and avoid asking users for seeds or private keys.
Frequently Asked Questions
Does Suite ever see my private keys?
No — signing operations happen on the Trezor device. Suite sends unsigned transaction data to the device and receives the signed transaction ready for broadcast.
Can I use Suite without a Trezor?
You can browse the interface but key operations — creating accounts, signing transactions — require a connected Trezor device.
What if I lose my device or it’s stolen?
If you lose the device but have a secure copy of your recovery seed, you can restore on a new compatible device. If you lose both the device and the seed, funds are unrecoverable.
