Ledger Flex: next‑gen security meets everyday usabilityLedger Flex is the French manufacturer’s answer to “one device for everything.” The 2.84‑inch E‑Ink screen finally brings full‑transaction preview without draining the 850 mAh battery — you get roughly 150 on‑chain sends before needing a top‑up.
Security stack. A certified CC EAL6+ Secure Element isolates your seed phrase, while an open‑source BOLOS OS lets devs audit firmware. Flex ships with touch‑to‑confirm and optional “Protection Mode” that bricks the device after 3 wrong PINs until you re‑enter the 24‑word recovery phrase.
Connectivity. USB‑C for initial setup, Bluetooth 5.2 for mobile, and NFC to pair with Ledger Live on desktop in <10 s. No Wi‑Fi keeps the attack surface tiny.
Asset coverage. Native Ledger Live supports 500+ coins; third‑party apps extend this to 5 500+ including Layer‑2 tokens. Flex stores up to 100 apps simultaneously — enough for most power users.
Everyday UX. The E‑Ink display remains perfectly readable in sunlight, and haptic feedback confirms each tap. The aluminium chassis weighs 57.5 g — lighter than a Nano X with protective case.
Bottom line. If you’re willing to pay flagship money for top‑shelf security and a paper‑like screen, Ledger Flex is arguably 2025’s most polished hardware wallet.
