You're choosing between two wallets that both understand the assignment: Bitcoin, nothing else. I like this matchup. Let me break down the differences that actually matter.
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 SeedSigner edges out the competition with superior features and community trust.
Side-by-Side Comparison
The specs that matter for Bitcoin security.
| Feature | Portal | SeedSigner |
|---|---|---|
| Price | $99 | $50 |
| Bitcoin-Only | Yes | Yes |
| Open-Source | Yes | Yes |
| Air-Gapped | No | No |
| Secure Element | Yes | None (software security only) |
| Connection | NFC only | QR codes only (air-gapped) |
Security Architecture
The security model is where you should start any comparison. Everything else is just features.
- Portal: NFC-based signing with secure element. No battery required.
- SeedSigner: DIY Raspberry Pi-based signing device. Stateless - generates keys from seed each time.
Both wallets are open-source. Good. That means you can verify the code yourself, or rely on the security researchers who already have. This is the baseline for serious Bitcoin storage.
What SeedSigner Does Better
Both are Bitcoin-only (good choice either way). 100% open-source hardware and software. Stateless: no keys stored on device.
Best for: Technical users who want maximum transparency, DIY enthusiasts, Budget-conscious Bitcoiners, Those who trust no company.
Portal's Weaknesses
My Take
SeedSigner is the most trustworthy option if you're technical enough to build it. You control every component in the supply chain. The stateless design means there's literally nothing stored on the device between sessions. But it's not for everyone. Assembly requires comfort with electronics. There's no warranty or support. If you can handle that, SeedSigner is hard to beat at ~$50 in parts.
The Price Question
SeedSigner is $49 cheaper at $50 versus Portal's $99. And it happens to be the better wallet too.
Who Should Buy Which?
If you value a focused, Bitcoin-only approach, go with SeedSigner. If a pure Bitcoin experience matters more, Portal is your pick. But for pure bitcoin security, I always lean toward the Bitcoin-only option.
What People Ask
