Jonas still advises the business. His work on core was unrelated to BitBox. 

Is Jonas Schnelli still affiliated with Bitbox? What happend that he steped down as a Bitcoin Core maintainer, mentioning legal risks. Did this lead to the bankruptcy of your predecessor company Shift Cryptosecurity AG?

We are proud to contribute to the Bitcoin open-source infrastructure in general, and have done so many times over the years contributing to BIPs or cryptographic libraries (eg. with anti-klepto).

The LIBBTC library I actually had to look up... :) It was created by our original co-founder Jonas Schnelli 10 years ago, and I think we used it in the BitBox01. Not quite sure yet, as that was before my time.

We are BitBox, makers of the open source BitBox02 - AMA!
