| Category | Winner | Why |
|---|---|---|
| Security Transparency | Trezor Safe 3 | Trezor's firmware is fully open-source — every cryptographic operation is auditable on GitHub. Ledger's firmware is closed-source. Both use CC EAL6+ secure elements, but only Trezor lets you verify what runs on them. |
| Mobile Connectivity | Ledger Nano X | The Ledger Nano X's Bluetooth 5.0 enables continuous wireless signing from iOS and Android via Ledger Live. No Trezor device has Bluetooth. The Trezor Safe 5 has NFC for tap interactions but not continuous sessions. |
| Display Quality | Ledger Flex | The Ledger Flex's 2.84-inch E-Ink touchscreen is the largest display on any hardware wallet. The Trezor Safe 5's 1.54-inch color touchscreen is smaller but renders in color. Both Nano and Safe 3 use tiny OLEDs. |
| Cryptocurrency Support | Trezor Safe 5 | Trezor supports 9,000+ cryptocurrencies versus Ledger's 5,500+. Trezor's open-source model allows community-contributed chain support. Ledger requires internal development for each new blockchain app. |
| Form Factor | Trezor Safe 3 | The Trezor Safe 3 at 13.1g and 59mm is the smallest and lightest hardware wallet. The Ledger Nano S Plus is close at 21g and 62mm. Premium models (Flex, Safe 5) are larger due to their touchscreens. |
