Ledger Stax & Flex (2025)
Overview
Ledger Stax ($399) and Flex ($249) represent Ledger's premium tier with large E Ink touchscreens, replacing the traditional button-based interface. The Stax features a 3.7-inch curved E Ink display; the Flex has a 2.8-inch flat screen. Both use Ledger's CC EAL6+ Secure Element chip, support 5,500+ assets, and connect via Bluetooth and USB-C. The E Ink displays show and persist your NFT or custom lock screen even when powered off.
Security Features
CC EAL6+ Secure Element (upgraded from EAL5+), Full touchscreen transaction verification, E Ink always-on lock screen (shows custom image/NFT), Bluetooth 5.2 and USB-C connectivity, Qi wireless charging (Stax only), NFC for tap-to-connect (future feature), Ledger Live integration, Optional Ledger Recover (encrypted cloud backup)
Pros & Cons
Pros: large readable screen for transaction verification, premium build quality, persistent NFT display, EAL6+ secure element, modern UX. Cons: expensive ($249-399), Ledger Recover controversy, closed-source secure element, Bluetooth adds theoretical attack surface, proprietary firmware, battery required (unlike Nano S Plus).
Setup Steps
1. Purchase from ledger.com only. 2. Verify security seal. 3. Charge the device (USB-C or wireless for Stax). 4. Open Ledger Live and follow setup wizard. 5. Generate and write down 24-word recovery phrase. 6. Set PIN code via touchscreen. 7. Install apps for your chains. 8. Optional: set NFT or custom image as lock screen. 9. Skip Ledger Recover unless you specifically want cloud backup.
Best For
Premium security buyers, NFT collectors who want to display artwork, users who want large-screen transaction verification, upgraders from Nano S/X
Tips & Recommendations
The E Ink screen is the killer feature — you can actually read and verify complex DeFi transactions before signing, which is painful on the tiny Nano screens. The Flex offers 90% of the Stax experience at $150 less (no curved screen, no wireless charging). Skip Ledger Recover unless you explicitly want the convenience trade-off.
