Trezor Safe 3

The Trezor Safe 3 is a compact USB-C hardware wallet built by SatoshiLabs, the Czech team that invented the hardware-wallet category back in 2014. It pairs a certified EAL6+ Secure Element with a fully open-source hardware and firmware design, giving you bank-grade chip protection paired with code you can audit yourself.

Despite its entry-level price (from $47 on sale, list $59), the Safe 3 ships with features that were once reserved for flagship wallets: a 0.96″ monochrome OLED screen, two-button on-device confirmation, PIN & passphrase entry directly on the device, and the new Single-share & Multi-share (Shamir) Backup system in the universal 20-word format. It also doubles as a FIDO2 / U2F two-factor authentication key for your online accounts.

The Safe 3 works with the free Trezor Suite desktop and web app — send, receive, trade and stake thousands of coins and tokens — and is compatible with popular third-party wallets such as Electrum, MetaMask and Rabby for reaching even more chains and assets.

On-device confirmation

Every transaction and sensitive action must be physically approved on the 0.96″ OLED screen using the two-button pad. If your computer or phone is compromised, the wallet still says no to anything you didn't verify on the device itself.

Trezor Suite — everything in one app

The free Trezor Suite desktop and web app lets you send, receive, trade and stake directly from your wallet, track your portfolio balance and review full transaction history — without ever exposing your keys to a third party.

Make your wallet a vault

Pin a second layer of security on top of your recovery phrase with a passphrase. The passphrase is entered directly on the device, creating a hidden wallet that simply doesn't exist without it — ideal for a plausible-deniability setup.

Modern wallet backup

Move on from fragile 12/24-word copies. The Safe 3 supports the new Single-share Backup (universal 20-word format) and can be upgraded to Multi-share Backup — a Shamir Secret Sharing scheme that splits your recovery material across multiple shares, so no single card fully reconstructs your wallet.

FIDO2 two-factor authentication

Plug in the Safe 3 and use it as a hardware 2FA key for supported services (Google, GitHub, Dropbox and more), replacing vulnerable SMS-based 2FA codes.

Privacy-first coin control

Trezor Suite includes coin-control labelling and built-in Tor support, letting you label UTXOs and route your connection through the Tor network to protect your identity while managing assets.

Universal & Bitcoin-only editions

Choose the Universal edition to manage thousands of coins and tokens, or the dedicated Bitcoin-only firmware if you want a minimal attack surface for a Bitcoin-only treasury.

Protected by an EAL6+ Secure Element

The Safe 3's onboard chip is certified to Common Criteria EAL6+, the same level used in banking and government hardware. It shields your PIN and passphrase against both invasive (physical) and non-invasive (side-channel) attacks that previously threatened open-source devices.

Security starts with open source

Trezor is famous for being fully open source — both the firmware and the hardware schematics are published. Independent researchers can audit every line, anyone can verify there's no backdoor, and the community can reproduce the device. Transparency is the foundation, and the Secure Element adds the physical armor on top.

On-device PIN & passphrase entry

Because the PIN and passphrase are typed on the wallet's own buttons (not on a potentially keylogged computer), a malware-infected host cannot capture the credentials needed to unlock your wallet.

Confidence from day one

Every Safe 3 ships with tamper-evident packaging and device security seals, so you can confirm the device has not been opened or interfered with before it reaches you.

Certified & travel-safe

All Trezor devices are CE and RoHS certified, meeting quality, reliability and environmental standards. They are X-ray safe and suitable for air travel, and operate from -20°C to +60°C.

SatoshiLabs is the Czech technology company behind the Trezor brand. Founded in 2014, SatoshiLabs shipped the world's first Bitcoin hardware wallet — the original Trezor Model One — effectively creating the hardware-wallet industry. Over a decade later the company remains an independent, security-first outfit headquartered in Prague.

Trezor devices are backed by an in-house support team, an active community, and the free Trezor Suite companion app (desktop, web and — in a limited form — Android). SatoshiLabs champions open-source development, publishing both firmware and hardware designs for public audit, and supports more than 9,000 coins and tokens across Trezor Suite and compatible third-party wallets.
