Protect your crypto with hardware-grade security and a user-first experience

Trezor brings rock-solid private key protection, open-source transparency and an intuitive interface together so you can hold, manage and transact crypto — with absolute confidence.

🛡️
Industry-leading security
Secure your private keys with air-gapped hardware and open-source firmware.

Cold storage made simple

Keep your keys offline and only sign transactions when you choose to.

Multi-coin support

Store Bitcoin, Ethereum, and thousands of tokens natively and via integrations.

Open-source & auditable

Fully transparent firmware and ecosystem for independent verification.

Recovery made resilient

Secure recovery seed handling and passphrase support for layered defenses.

Why professionals and beginners trust Trezor

Trezor is designed for people who demand stronger protection than a password can deliver. Whether you're building long-term savings, trading actively, or managing custody for clients, the wallet architecture emphasizes clarity over complexity and security by design.

Built around three core principles

  • Ownership: You control the keys—never a third party.
  • Transparency: Open-source firmware and public audits.
  • Simplicity: Clear UX flows that avoid hidden actions.

Hardware-isolated keys

Private keys never leave the device. Transactions are signed inside the isolated environment and only the signed transaction is transmitted, dramatically reducing attack surface and exposure to malware on your computer.

Verified recovery & passphrase

Recover your wallet securely with industry-standard mnemonic phrases. Optional passphrase support acts as a 25th word and creates a hidden wallet—an effective privacy and backup strategy used by professionals.

Broad ecosystem integrations

Connect with major wallets, exchanges and DeFi interfaces while keeping signing on-device. Trezor is compatible with desktop and web tools that implement secure signing flows.

Security deep-dive

Security is not a single feature—it's a layered process. Trezor combines hardware protections, firmware safeguards and operational best-practices to protect funds across the entire lifecycle: creation, storage, signing and recovery.

Hardware protections

Secure chipsets, tamper-evident casings and isolated execution environments make physical attacks costly and detectable. Our designs prioritize minimal attack surface and deterministic behavior that is simple to audit.

Open-source scrutiny

Full firmware source is public so third-party auditors and security researchers can and do inspect the codebase. This transparency ensures vulnerabilities are found and fixed quickly, and that the device behaves exactly as documented.

Operational best practices

Use official firmware updates, verify device fingerprints, generate seeds in a private setting, and consider passphrase protection for high-value holdings. For organisations, combine hardware keys with multi-signature setups and well-defined key rotation policies.

How it works — from unboxing to secure signing

1. Unbox & verify

Check tamper-evidence, power up the device and verify the serial/fingerprint shown in the app. This step prevents malicious substitutions.

2. Create your seed

Generate your mnemonic inside the device. Write the recovery words on paper or a steel backup and store them in a secure place offline.

3. Connect securely

Use the official Trezor Suite or supported wallet connectors to view balances and create unsigned transactions locally. The device signs transactions after you verify them on-screen.

Developer & enterprise friendly

APIs, developer tools and enterprise integration frameworks exist to incorporate hardware signing into custody services, signing policies and automated workflows—all while retaining the core guarantee: private keys stay in hardware.

Frequently asked questions

Can I lose my funds if I lose the device?

No — as long as you have a secure copy of your recovery phrase. The recovery seed allows you to recreate your keys on a new compatible device. Keep your seed offline and protected.

Is the firmware really open-source?

Yes. Full firmware repositories are public for inspection and community contribution. That openness helps detect problems early and builds trust through independent review.

Which coins are supported?

Trezor supports Bitcoin, Ethereum and thousands of ERC tokens natively or via integrations. Check the compatibility list in the support center for the most up-to-date coverage and third-party connectors.

How do I update firmware safely?

Always use the official suite and follow on-screen verification. Firmware updates are cryptographically signed and the device verifies signatures before applying them.
