Nice improvements to Trezor's security model with Safe 3 and Safe 5. 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. Safe 5 screen is slick and touchscreen + haptic feedback work exactly as I'd expect. Ledger 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. On the complex bitcoin transaction signing performance side, Safe 5 is the fastest Trezor yet and is only exceeded by BitBox02. Ledger, on the other hand, is looking to have worse signing performance than the Nano S Plus. SAD! Props 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!
