Cryptocurrency security starts with private keys. Software wallets and exchanges hold keys on internet-connected devices, making them vulnerable to hacks, malware, and phishing. A hardware wallet like Trezor stores private keys in a secure, offline environment — the device — and only exposes signed transactions. In practice, that means attackers cannot extract your keys remotely, even if your computer is compromised.
Keys are generated and used only on the device.
You verify and approve every action on the device screen.
A recovery seed lets you restore funds if the device is lost or damaged.
Supports Bitcoin, Ethereum, and many ERC-20 tokens and altcoins.
Trezor offers multiple models to match different needs. Model T provides a touchscreen and extended coin support for power users and developers. Trezor One is compact, reliable, and ideal for users who want robust security at a lower price point. Choose based on interface preference, coin support, and budget.
Never store your recovery seed online or share it; treat it like cash in a safe.
Trezor can be part of a multisig wallet where multiple devices or keys must sign a transaction. This is useful for teams, treasury management, or enhanced personal security. Integrations with popular wallets and services also allow you to participate in staking, DeFi, and other on-chain activities while keeping keys offline.
Trezor publishes firmware and tools as open-source projects. This transparency allows security researchers and the community to audit code and contribute improvements. Firmware updates are signed and applied with user consent on-device to prevent malicious updates.
Developers can use Trezor Connect or the lower-level API to integrate hardware-backed signing into applications. These APIs help apps request address displays, transaction signing, and device info while relying on user confirmations on the device itself.
Trezor signs transactions but does not broadcast them — wallet software or services you use handle broadcasting and may reveal addresses to nodes or APIs. To enhance privacy, consider using your own node, privacy-preserving services, or coin-join tools where appropriate.
