Ledger Nano X
A plan byLedger
Ledger is the world's most popular hardware wallet maker: cold-storage devices with a certified secure element (EAL5+/EAL6+) where private keys never leave the chip. The range spans the Nano S Plus (≈€79), the Bluetooth Nano X (≈€149), up to the touchscreen Flex (≈€249) and Stax (≈€399), all managed through the Ledger Live app supporting thousands of assets across 100+ blockchains. A contentious point for the cypherpunk community: firmware and secure element are closed-source, and in 2023 the optional Ledger Recover service raised concerns about seed extraction.

Verdict
Score 4.5/5, outstanding profile. In its favour: certified secure element (EAL5+/EAL6+); support for thousands of assets; range from €79 to €399; mature Ledger Live app. The trade-off to weigh: closed-source firmware and secure element; Ledger Recover controversy (2023); USB/Bluetooth connection, not air-gapped.
On the Sovereignty lens the score is 4.4/5 (very strong): the strength is fund control (5.0/5), while trustless / auditability (3.8/5) is the weak link.

FAQ
How much does a Ledger cost?
The entry-level Nano S Plus costs about €79. The Bluetooth Nano X about €149, the touchscreen Flex about €249, and the flagship Stax about €399.
Is Ledger open source?
Only partly: the apps and part of the software stack are public, but the firmware and the secure element are closed-source. That's why we classify it as partially open-source.
Can private keys ever leave a Ledger device?
Under normal use no: they stay inside the secure element. The optional Ledger Recover service, introduced in 2023 and off by default, can export an encrypted, split version of the seed to third-party providers, which is what drew criticism.
