Developing a Secure Element is an expensive and time-consuming process to get the Evaluation Assurance Level (EAL5+ or EAL6+) certification. This is the reason we have very few open-source projects. I wish all success SatoshiLabs the sister company Tropic Square's with Tropic01 ( https://tropicsquare.com/tropic01 ) not only for their hardware wallet, but also their ambition for commercial secure IoT—this is more than necessary for cybersecurity these days. Congratulations!👏
