> This is based on an EAL6+ chip from a large SE vendor that also protects billions of credit cards and passports. You mentioned the NXP SE050 before which is marketed as an IoT chip ... Nitrokey uses the NXP P5DF081 which is more geared towards smart card use but otherwise not much different.

SmartMX1 (P5 series) is a dinosaur. SmartMx2, the successor, was introduced in about 2010 and it is at P71/SmartMX3 now. SE050 is similar to the Infineon Optiga ones. Both are better than ATECC. The problem is there is no SEs supporting Bitcoin algorithms, or content-aware signing (so you can for example block a Request to Vanish event from ever being signed)

Not sure what's so special about Bitcoin algorithms other than the koblitz curve but neither do I care. As for content aware signing not the role of the SE to my knowledge.
