Krux does one thing: secure your bitcoin. Trezor Model One tries to support thousands of tokens. Different philosophies, different risk profiles. Let me walk through it.
I've used both of these wallets. I know how they feel in your hand, how the software works, and where they cut corners. Here's the honest breakdown.
The Bottom Line
Krux wins by virtue of being Bitcoin-only. Why would you trust your sats to a device cluttered with altcoin code?
What Krux Does Better
Best for: Technical users who want hardware choice, SeedSigner alternatives, Budget-conscious DIYers, Those who want specific form factors.
What Holds Trezor Model One Back
- Multi-coin support introduces unnecessary risk
- No secure element
- Multi-coin bloat
- Dated design
- Small screen
The core issue: Trezor Model One supports altcoins. For serious Bitcoin storage, that's a liability, not a feature.
How They Compare
The specs that matter for Bitcoin security.
| Feature | Krux | Trezor Model One |
|---|---|---|
| Price | $40 | $49 |
| Bitcoin-Only | Yes | No |
| Open-Source | Yes | No |
| Air-Gapped | No | No |
| Secure Element | None (software security) | None |
| Connection | QR codes only (air-gapped) | USB |
How They Handle Security
Security is the whole point. Everything else is secondary. Here's how these two handle it:
- Krux: Stateless DIY signing device. Similar concept to SeedSigner but supports more hardware.
- Trezor Model One: Software security without dedicated secure element. The pioneer.
Krux is open-source. Trezor Model One uses proprietary firmware. I've said it before: "verifiable source" is not the same as open-source. One lets you audit. The other lets you look but not build. I trust the approach where the community has full access.
My Take
Krux is excellent if you want DIY flexibility. The hardware options mean you can actually find parts when Raspberry Pis are scarce. The stateless design is sound. At $40 or less in parts, the price is right. It's slightly less polished than SeedSigner but the multiple device support is a real advantage. For technical users who want choice, Krux delivers.
On Altcoin Support
Every altcoin Trezor Model One supports is code that could compromise your bitcoin keys. Krux doesn't carry that weight. Bitcoin-only firmware is leaner and more auditable.
Price & Value
$40 versus $49. Close enough that price shouldn't be a factor. Focus on the security features and firmware approach instead.
