The Trezor Safe 3 represents a significant evolution for Trezor: it’s the first Trezor device to include a certified secure element chip while maintaining the fully open-source firmware that has made Trezor the gold standard for transparency in the hardware wallet space. After extensive hands-on testing, I can confirm it’s one of the most compelling hardware wallets available in 2026 — particularly for users who prioritize auditability and privacy.
The Trezor Safe 3 earns a 8.9/10 overall score. It combines Trezor’s legendary open-source transparency with a new EAL6+ certified secure element chip, excellent Shamir Backup support, and a clean, intuitive interface. The main limitations are the USB-C only connectivity (no Bluetooth) and the smaller coin selection compared to Ledger.
| Category | Score | Notes |
|---|---|---|
| Security | 9.3 / 10 | EAL6+ secure element + 100% open-source firmware |
| Transparency | 10 / 10 | Fully auditable firmware on GitHub; no closed components |
| Ease of Use | 8.5 / 10 | Trezor Suite is clean; physical buttons are responsive |
| Coin Support | 8.8 / 10 | 8,000+ coins; no native Cardano or XRP support |
| Backup Options | 9.5 / 10 | Shamir Backup (SLIP39) is industry-leading |
| Value for Money | 8.8 / 10 | Competitive price for the security level offered |
The Trezor Safe 3 uses the Optiga Trust M (SLx9670) secure element, certified to Common Criteria EAL6+ — one level higher than Ledger’s EAL5+ chip. This chip stores the private keys and handles all cryptographic operations in an isolated, tamper-resistant environment.
What makes Trezor unique is that all firmware is fully open source and available on GitHub. This means any security researcher in the world can audit exactly what the device does. Trezor has been audited by multiple independent security firms, and the results are publicly available. This is the gold standard for transparency in the hardware wallet industry.
Shamir Backup (SLIP39) is Trezor’s most powerful security feature. Instead of a single 24-word seed phrase, you can split your backup into multiple shares (e.g., 3-of-5). You need any 3 of the 5 shares to recover your wallet. This eliminates the single point of failure that a standard seed phrase represents. Store shares in different locations, give one to a trusted family member, keep one in a bank vault — the flexibility is exceptional.
No Bluetooth is actually a deliberate security choice by Trezor. Wireless communication creates additional attack surface. USB-C only means there’s one well-understood communication channel, which is easier to audit and secure.
The Trezor Safe 3 setup via Trezor Suite took approximately 15 minutes. The process walks you through:
The PIN entry system is particularly clever: the device shows a 3×3 grid with numbers in random positions, and you click the corresponding positions on your computer screen. Since the positions change every time, a keylogger or screen recorder cannot capture your PIN.
Trezor Suite is a clean, well-designed desktop and web application. Key features include:
The Tor integration is a standout feature — enabling it routes all Trezor Suite traffic through the Tor network, preventing your IP address from being linked to your wallet addresses. This is a significant privacy advantage over Ledger Live.
The Trezor Safe 3 supports 8,000+ cryptocurrencies, including Bitcoin, Ethereum (all ERC-20 tokens), Solana, Polygon, BNB Chain, and most major networks. Notable gaps compared to Ledger: Cardano (ADA) is not natively supported in Trezor Suite (though third-party wallets like Adalite work), and XRP support requires using a third-party interface.
For most users holding BTC, ETH, and major altcoins, the coin support is more than adequate.
| ✅ Pros | ❌ Cons |
|---|---|
| 100% open-source, fully auditable firmware | No Bluetooth (USB-C only) |
| EAL6+ certified secure element | No native Cardano or XRP in Trezor Suite |
| Shamir Backup — best backup system available | Smaller screen than Ledger Nano X |
| Built-in Tor support for privacy | No battery (requires USB connection) |
| Competitive price for security level | Trezor Suite less feature-rich than Ledger Live for DeFi |
The Trezor Safe 3 is the right choice if you:
The Trezor Safe 3 scores 8.9/10. For users who prioritize transparency and auditability, it’s the best hardware wallet available. The combination of open-source firmware and a certified secure element closes the gap with Ledger while maintaining Trezor’s philosophical commitment to full transparency. If you don’t need Bluetooth and your portfolio is primarily BTC/ETH, this is an excellent choice.
Always purchase directly from the official manufacturer to guarantee you receive a factory-sealed, uncompromised device. Never buy hardware wallets from Amazon, eBay, or third-party sellers.
