Good job, security is #1. It's soooo annoying that we have to relevel our axies in adventure mode ater doing stuff like this. Oh well, it's worth it. At least you never have to do it again :-P
I'm looking forward to more security options for NFTs in general, there still aren't enough options for safe long-term storage of high-value NFTs.
I believe that the only Ronin will use Trezor for security for now since the developers are more focused on Land as well as v2 gameplay.
