Ledger Flex

What works

  • CC EAL6+ certified secure element is the highest security certification in consumer hardware wallets — Trezor uses EAL5+ on the Safe 5
  • Bluetooth + NFC enables wireless signing on mobile — no cable required for iOS/Android transactions
  • 5,500+ coin support via Ledger Live is the broadest ecosystem in hardware wallets — covers obscure altcoins most competitors miss

What doesn't

  • Ledger's 2023 Recover announcement revealed the firmware could export seed shards — closed-source firmware means users cannot independently verify this is disabled
  • $249 is $50 more than the Trezor Safe 5 for largely equivalent security outcomes in practice

Trezor Safe 5

What works

  • Fully open-source firmware — every line of code is publicly audited on GitHub; Ledger's secure element firmware remains closed
  • Shamir Backup (SLIP39) splits seed into multiple shares — lose one share without losing access; more resilient than standard BIP39 single-seed backup
  • $169 vs $249 — $80 less than the Ledger Flex for comparable security outcomes from an open-source-verified device

What doesn't

  • USB-C only — no Bluetooth or NFC; requires cable connection for every transaction
  • 1.54-inch screen is smaller than Ledger Flex — transaction details require more scrolling to verify

Bottom line

Our pick: Trezor Safe 5.
