Price
The Model One is one of the cheapest hardware wallets available at ~$49. The Safe 5 costs ~$169 — more than three times as much.
The Model One’s low price makes it an excellent entry point for anyone who wants hardware wallet security without a large upfront investment. For most users storing moderate amounts, it delivers the essential protection at minimal cost.
The Biggest Difference: Secure Element Chip
This is the most significant technical distinction between the two devices.
Trezor Safe 5:
- Has a secure element chip (EAL6+ certified)
- The secure element physically protects the private key against hardware attacks
- Even if someone disassembles the device, extracting the key requires defeating the chip’s physical security
Trezor Model One:
- No secure element chip
- Uses a general-purpose microcontroller (STM32)
- Vulnerable to advanced hardware extraction attacks (requires physical access and significant expertise)
- Trezor mitigates this with open-source firmware and passphrase protection
In practice: For the vast majority of users, this difference doesn’t matter — typical theft scenarios involve phishing or social engineering, not sophisticated hardware attacks. But for users storing large amounts who face higher threat models, the secure element provides meaningful additional protection.
Screen and Interface
Safe 5: Large colour touchscreen. You can see full transaction details, NFT images, and interact by tapping. The modern interface is significantly easier to use than button-based navigation.
Model One: Small OLED display with two physical buttons. The screen shows about two lines of text at a time. Navigating menus requires clicking through multiple screens.
For day-to-day use — setting up, confirming transactions, checking addresses — the Safe 5’s touchscreen is noticeably more comfortable. The Model One’s interface is functional but dated.
Shamir Backup (Safe 5 only)
The Safe 5 supports Shamir Secret Sharing — an advanced backup method where your seed phrase is split into multiple shares (e.g. 3 of 5 shares required to recover).
This lets you:
- Store shares in multiple locations (home, bank, trusted family member)
- Require a threshold to reconstruct (2 of 3, 3 of 5, etc.)
- Eliminate the single point of failure of a standard 12/24-word backup
The Model One uses standard BIP39 backup (12 or 24 words) — one phrase that recovers everything. Shamir isn’t available.
For high-value storage, Shamir backup is a meaningful security upgrade.
Coin Support: Identical
Both devices support the same 9,000+ cryptocurrencies through Trezor Suite, including:
- Bitcoin, Ethereum, Litecoin, Dogecoin, Cardano, Solana
- All ERC-20 tokens via the Ethereum account
- Monero (XMR) — a notable inclusion that many hardware wallets don’t support natively
There is no difference in coin support between the Safe 5 and Model One.
Open Source: Both Fully Open Source
Trezor is unique in the hardware wallet space for being fully open source — hardware design, firmware, and software are all public.
This applies to both the Safe 5 and Model One equally. Security researchers can (and do) audit the code. This transparency is a core part of Trezor’s security model.
Ledger, by comparison, uses a partially closed secure element. Trezor’s approach is different — they compensate for no secure element on the Model One with full code transparency and rely on the passphrase feature to protect against physical attacks.
Passphrase: The Model One’s Best Security Feature
Both devices support an optional passphrase (sometimes called the 25th word):
- A passphrase creates a completely separate wallet on top of your seed
- Even if someone obtains your 12/24 words, they can’t access funds without the passphrase
- The passphrase is never stored on the device
For Model One users storing significant funds, enabling a strong passphrase effectively closes the hardware extraction vulnerability. Trezor explicitly recommends this for higher-security setups.
USB Connection
- Safe 5: USB-C — the modern standard, widely available cables
- Model One: Micro-USB — older standard, cables less common but still available
Not a major factor, but USB-C is more convenient for modern users who already carry USB-C cables.
Who Should Buy Each?
Buy the Trezor Model One if:
- You’re new to hardware wallets and want to try one affordably
- You’re storing a modest amount (under $5,000–$10,000)
- You want maximum open-source transparency with a proven track record
- You’ll use a strong passphrase for additional security
- You’re buying a backup device
Buy the Trezor Safe 5 if:
- You’re storing a significant amount and want the best physical security
- You want Shamir Backup for distributed key storage
- You want a modern touchscreen interface
- You’re comfortable paying for a premium device
- You face a higher-than-average threat model (public figure, large holdings)
The honest verdict
The Model One is excellent value for most people. At $49 with a passphrase enabled, it’s a very secure device. The open-source firmware means the security model is fully auditable.
The Safe 5 makes sense if you’re storing a significant amount, want the peace of mind of a secure element chip, and value Shamir Backup. It’s a genuinely better device — the question is whether the improvements justify the price difference for your situation.
What About the Trezor Safe 3?
Trezor also sells the Safe 3 (~$79) — a middle option with a secure element chip but a smaller button-based interface (no touchscreen). It’s a reasonable choice if you want the secure element at a lower price than the Safe 5 but don’t need the touchscreen.
| Model | Price | Secure Element | Touchscreen | Shamir |
|---|---|---|---|---|
| Model One | ~$49 | No | No | No |
| Safe 3 | ~$79 | Yes | No | Yes |
| Safe 5 | ~$169 | Yes | Yes (colour) | Yes |
Frequently Asked Questions
Can I use the same seed phrase on Model One and Safe 5?
Yes. Trezor wallets use standard BIP39 seeds — you can restore a Model One seed on a Safe 5 and vice versa. Many users do this to upgrade devices or maintain a backup.
Is the Model One still supported?
Yes, as of 2026 Trezor still sells and supports the Model One. It receives firmware updates.
Is the Model One’s lack of secure element a real security risk?
Only for physical attacks — if someone steals your device, they could theoretically attempt hardware extraction. This is mitigated by a strong passphrase. For remote attacks (phishing, malware), neither device is vulnerable because the key never touches your computer.
Which is better for Bitcoin only?
Either works perfectly for Bitcoin. The Model One is a classic Bitcoin wallet used by many long-term holders.
Does the Safe 5 support Monero?
Yes. Trezor is one of the few hardware wallets with native Monero support on both models.
