Two Bitcoin-only wallets. Both refuse to touch altcoin code. That already puts them ahead of 90% of the market. But you're here because you want to know which one deserves your sats. Fair enough.
I've tested both of these wallets and formed opinions the old-fashioned way: by actually using them. Here's what stood out.
The Bottom Line
Both are solid Bitcoin-only choices, but Foundation Passport edges out the competition with superior features and community trust.
Foundation Passport's Advantages
- Both are Bitcoin-only (good choice either way)
- Air-gapped operation for maximum security
- Beautiful design and build
- Fully open-source
Best for: Users who want premium build quality, Those who value air-gapped + open-source combination, Bitcoin-only maximalists with budget for premium device, Users who prefer physical controls over touchscreens.
What Holds SeedSigner Back
Requires direct connection (potential attack vector). Requires DIY assembly. No commercial support.

Security Architecture
Let's get into what actually matters: how these wallets protect your bitcoin.
- Foundation Passport: Open-source with secure element. Premium build quality.
- SeedSigner: DIY Raspberry Pi-based signing device. Stateless - generates keys from seed each time.
Open-source on both sides. That's how it should be. Neither wallet asks you to trust a black box. The code is out there for anyone to audit.
Foundation Passport supports air-gapped operation via QR codes. Your private keys never have to touch a networked device. Every USB cable, every Bluetooth connection is an attack surface you don't need.
My Take
The Passport is the premium choice and it knows it. The build quality justifies part of the $199 price tag. The open-source firmware and air-gapped capability put it in the same tier as the Jade Plus. But it's larger and heavier. If you want something that feels substantial and looks good on a desk, get the Passport. If portability matters, the Jade Plus does air-gapped better in a smaller package.
Price & Value
SeedSigner costs less at $50, but the $149 you'd save isn't worth the trade-offs. Foundation Passport earns its price tag.
Market Context
The hardware wallet market has matured. Foundation Passport and SeedSigner represent two approaches to the same problem: keeping your bitcoin safe from everyone except you. The wallets that survive long-term will be the ones that take security seriously and respect the self-custody ethos.
Who Should Buy Which?
If you value a focused, Bitcoin-only approach, go with Foundation Passport. If a pure Bitcoin experience matters more, SeedSigner is your pick. But for pure bitcoin security, I always lean toward the Bitcoin-only option.
