SafePal S1
score
Fees: low one-time device cost; free app
A budget-friendly air-gapped option for users who want broad chain coverage without spending much. The caveat is limited transparency and closed firmware, so it asks for more trust than open-source alternatives at higher security tiers.
What the SafePal S1 is
The SafePal S1 is a low-cost, air-gapped hardware wallet that signs transactions via QR codes, with no USB, Bluetooth or Wi-Fi connection. Backed by Binance, it uses an EAL5+ secure element and is operated entirely through the free SafePal app, which also bundles exchange and DeFi features. A self-destruct mechanism is designed to wipe the device if it detects physical tampering.
How it measures up
Value is the headline at 9: you get air-gapped signing and a secure element for a very low price. Supported assets score 8.5 thanks to wide multi-chain coverage through the app, and the app and UX land at 7.5. The security model is a solid 7, held back from higher by the weakest criterion here, transparency at 5, since the firmware is closed-source and cannot be independently verified.
What it costs
The S1 is one of the cheapest ways to get into air-gapped cold storage, a low one-time device cost with a free app, which is exactly why value scores so highly. There is no subscription, though the app's integrated swap and DeFi services route through third parties with their own terms.
Where to be cautious
Closed-source firmware means you are trusting SafePal rather than auditable code, a meaningful gap versus open-source wallets at higher security tiers. Some users also view the Binance backing as a centralisation concern, and the app's bundled exchange and DeFi features widen the trust surface beyond pure key storage. None of these are dealbreakers at the price, but they are the reason the overall score is where it is.
Who it is for
The SafePal S1 fits budget-conscious users who want broad chain coverage and air-gapped signing without spending much, and are comfortable trading some transparency for the low price. If verifiable open-source firmware is a priority, spend more on an audited alternative. This is a review of what the device offers, not advice on your holdings.

Is the SafePal S1 safe?
+
It is air-gapped with an EAL5+ secure element and a tamper self-destruct feature, scoring 7 on our security model. The catch is closed-source firmware, so transparency scores only 5 and you are trusting SafePal rather than auditable code.
How much does the SafePal S1 cost?
+
It is one of the cheapest air-gapped wallets available, a low one-time cost with a free app, which is why value scores 9. There is no subscription, though the app's built-in swap and DeFi services involve third-party fees.
Does SafePal being owned by Binance matter?
+
SafePal is backed by Binance, which some users see as a centralisation concern for a self-custody product. It does not change the fact that you hold your own keys, but it is a factor worth considering if you prefer independent projects.
What coins does the SafePal S1 support?
+
It supports a wide range of chains and tokens through the SafePal app, scoring 8.5 on supported assets, which is generous for the price. Check the app's list against the specific coins you hold.
How does SafePal S1 signing work?
+
It is air-gapped and uses QR codes: the app shows a transaction QR, the S1 scans and signs it offline, and you scan the signed result back. No USB, Bluetooth or Wi-Fi is involved.
