SeedSigner runs Bitcoin-only firmware. Ledger Nano S Plus decided to support altcoins too. One of these approaches is correct. But I'll lay out the full picture so you can see for yourself.
I got hands-on with both of these. Setup, daily use, edge cases. Let me walk you through what I learned.
Ledger Nano S Plus: Security Incidents You Should Know
May 2023: Ledger Recover Capability
Same firmware architecture allows seed extraction like Nano X.
These aren't hypothetical risks. They happened. When a company has multiple critical security incidents, you have to ask: why would you trust them with your bitcoin?
The Bottom Line
SeedSigner wins by virtue of being Bitcoin-only. Why would you trust your sats to a device cluttered with altcoin code?
Side-by-Side Comparison
The specs that matter for Bitcoin security.
| Feature | Ledger Nano S Plus | SeedSigner |
|---|---|---|
| Price | $59 | $50 |
| Bitcoin-Only | No | Yes |
| Open-Source | No | Yes |
| Air-Gapped | No | No |
| Secure Element | ST33K1M5 (closed-source) | None (software security only) |
| Connection | USB-C | QR codes only (air-gapped) |
Under the Hood: Security
Security is the whole point. Everything else is secondary. Here's how these two handle it:
- Ledger Nano S Plus: Closed-source secure element. Same trust issues as Nano X.
- SeedSigner: DIY Raspberry Pi-based signing device. Stateless - generates keys from seed each time.
SeedSigner publishes everything. Full open-source firmware that anyone can audit, build, and verify. Ledger Nano S Plus keeps things closer to the chest. When it comes to securing your bitcoin, I want to verify, not trust.
On Altcoin Support
Ledger Nano S Plus supports altcoins. Every line of altcoin code is code that could have a vulnerability. It's code that doesn't serve your bitcoin. SeedSigner is Bitcoin-only: focused firmware for a focused purpose.
What SeedSigner Does Better
Best for: Technical users who want maximum transparency, DIY enthusiasts, Budget-conscious Bitcoiners, Those who trust no company.
What Holds Ledger Nano S Plus Back
The core issue: Ledger Nano S Plus supports altcoins. For serious Bitcoin storage, that's a liability, not a feature.
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
Both wallets are priced similarly at $59 and $50. At this range, price is irrelevant. Pick the one with the security model that makes more sense for your bitcoin.
Who Should Buy Which?
Budget-conscious? SeedSigner costs less. Security-focused? Go with SeedSigner. New to self-custody? Either will work, but start with the one that keeps things simple.
What People Ask
Are Ledger Nano S Plus and SeedSigner Bitcoin-only?

SeedSigner has the edge on security. Bitcoin-only firmware means a smaller codebase and fewer potential vulnerabilities.
Is the price difference worth it?
The price difference is small. Focus on security features, not the $9 difference.
