KeepKey
KeepKey LLC
KeepKey, from KeepKey LLC (based in Denver, Colorado), is one of the cheapest hardware wallets on the market: about $60 (~€55). The firmware is open-source and the company emphasizes device auditability. Its large display shows every transaction for physical confirmation and the private key never leaves the device; backup uses the classic 12/24-word seed phrase (BIP-39). It is multichain: it claims 11 native chains plus all EVM tokens (Bitcoin, Ethereum, Litecoin, Solana, TON, TRON and thousands of assets). ⚠️ Unlike many rivals in the same price bracket, KeepKey has historically shipped without a dedicated secure element: protection relies on PIN and passphrase on a general-purpose microcontroller. We flag it as lacking a secure element unless proven otherwise by the datasheet; the USB port type is also unconfirmed on the store, so this card is marked partial.

Plans & pricing
Strengths
- Very low price (~€55); open-source firmware and hardware presented as auditable; large display for transaction confirmation; multichain (11 native chains + EVM tokens).
- Self-custody: funds stay in your wallet — the platform cannot touch them.
- No KYC: usable without identity verification.
- Open-source, verifiable code.
- Self-hostable: you can run your own instance or node.
Weaknesses
- No dedicated secure element declared: security relies on PIN/passphrase on the microcontroller, a lower level than rivals with a certified secure element; USB connection (not air-gapped); port type and some hardware details unconfirmed on the store.
- No notable sovereignty drawback documented.
Verdict
Score 3.9/5, solid profile. In its favour: very low price (~€55); open-source firmware and hardware presented as auditable; large display for transaction confirmation; multichain (11 native chains + EVM tokens). The trade-off to weigh: no dedicated secure element declared: security relies on PIN/passphrase on the microcontroller, a lower level than rivals with a certified secure element; USB connection (not air-gapped); port type and some hardware details unconfirmed on the store.
On the Sovereignty lens the score is 4.8/5 (outstanding): the strength is fund control (5.0/5), while privacy & anonymity (4.5/5) is the weak link.

FAQ
How much does a KeepKey cost?
KeepKey costs about $60 ($59.95 on the official store, ~€55), among the lowest prices in the category. Orders ship from the United States (Denver): any duties, VAT and clearance fees are the buyer's responsibility.
Does KeepKey have a secure element?
Historically no: KeepKey has shipped without a dedicated secure element and relies on PIN and passphrase on a general-purpose microcontroller. We classify it as lacking a secure element unless proven otherwise by the current datasheet. This is a meaningful difference from rivals with a certified secure element.
Which coins does KeepKey support?
It is multichain: it claims 11 native chains plus all EVM tokens, including Bitcoin, Ethereum, Litecoin, Solana, TON and TRON, for several thousand assets. Backup uses the standard 12/24-word seed phrase (BIP-39).
