The addition of a secure element mitigates the old physical seed extraction vulnerability. Also, the chip in the Safe 5 mitigates glitching attacks and has additional anti-tamper features.\n\nSafe 5 screen is slick and touchscreen + haptic feedback work exactly as I'd expect.\n\nLedger flex e-ink screen is also nice and I really hope the longevity of it is better than what we saw on Nano S devices with many experiencing screen failure after a few years.\n\nOn the complex bitcoin transaction signing performance side, Safe 5 is the fastest Trezor yet and is only exceeded by BitBox02.\n\nLedger, on the other hand, is looking to have worse signing performance than the Nano S Plus. SAD!\n\nProps to both Ledger and Trezor for shipping new hardware that is compatible with existing APIs and SDKs. As a result, these devices were automatically usable with Casa's software!"}
