Overview
Trézor Suite is a polished desktop and web application built to make hardware wallet operations simple and secure. It connects to your Trezor hardware device over a secure channel, lets you manage multiple accounts and currencies, and provides an easy workflow for sending, receiving and reviewing transaction history. The application is intentionally minimal where it matters and comprehensive where users need clarity.
This page is a template and informational overview to help designers, developers and content authors create an approachable product description for a hardware wallet app. It covers core features, the security model, step-by-step setup instructions, and answers common questions about usability and backups.
Key Features
- Hardware-backed private keys: Your keys never leave the hardware device. Transactions are signed on-device and verified before broadcasting.
- Multi-currency support: Built-in compatibility for major coins and tokens with a modular structure to add new networks smoothly.
- Transaction preview: Clear, human-readable previews of every outgoing transaction, including destination, amounts, and fees.
- Account management: Create multiple accounts, label addresses, and organize portfolios with an intuitive dashboard.
- Secure firmware updates: Verified updates with cryptographic signatures to ensure authenticity and integrity.
- Privacy controls: Local address generation, optional network routing, and transparent telemetry controls.
Security Model — How Private Keys Stay Private
The central security guarantee of a hardware wallet app is that private keys are generated and remain stored inside the physical device. The Suite never exports private keys or raw seeds. When you make a transaction, the unsigned transaction data is transmitted to the device, the device displays a confirmation screen, and only after explicit approval does it sign the transaction and return the signature. This pattern prevents remote attackers from extracting keys even if the host computer is compromised.
In addition to on-device signing, the app provides step-by-step checks for recovery seed setup, encourages the use of passphrases, and uses authenticated firmware update channels to avoid supply-chain risks. User education and clear UI prompts are part of the security design — users are guided through irreversible actions like wiping a device or restoring from seed with prominent warnings and confirmations.
How It Works — Short Walkthrough
- Download & install: Choose the desktop app for your OS or open the web app when connecting a device locally.
- Connect your hardware wallet: Use USB (or other supported link) and confirm the connection on the device screen.
- Create or restore a wallet: Generate a new seed on the device, write it down safely, or restore from an existing seed phrase.
- Manage accounts: Create accounts for different currencies or purposes and optionally set labels for easy identification.
- Sign transactions: Compose a transaction in the Suite, verify details on your device screen, and confirm to sign and broadcast.
The Suite also integrates helpful tools like address verification, message signing, and exportable transaction history to support advanced auditing and bookkeeping.
Getting Started
Beginners should follow these recommended steps to reduce risk: first, obtain a genuine hardware device from an authorized retailer. When you first initialize, create a new seed on the device — never restore a seed that you typed into a computer. Write the recovery phrase on the supplied cards or a robust steel backup and store it in a secure place. Optionally set a passphrase for deniability and greater account separation.
After setup, connect the device anytime you want to interact with funds. Regularly check for firmware updates in the Suite and read release notes to understand changes. For everyday balances, consider using smaller hot wallets and keep larger holdings cold whenever possible.
FAQ
Is my seed phrase ever transmitted to the computer?
No. Seed phrases are created and stored on the hardware device only. The Suite will never ask you to type or send your seed over the internet. If you are asked to enter your seed into a website, treat it as a phishing attempt and disconnect immediately.
Can I use the Suite on multiple machines?
Yes. The Suite is stateless with regard to private keys: you can connect the same hardware device to different machines and the device will present the same accounts. Always ensure you download the Suite from a trusted source or verify official signatures.
What happens if I lose my device?
If you lose the physical device, you can restore access to your funds by purchasing a compatible hardware wallet and restoring it using your recovery seed. This makes the security of your physical seed backup critical.
For Developers
The architecture favors modular network adapters and a clean API for adding coin support. UI components are designed to be accessible and localized. If you are implementing a new network plugin or integration, follow the signing and address-derivation standards for your target ecosystem and include thorough unit tests to validate behavior. Always test signing flows on-device — simulators cannot fully replace hardware testing.
