What differentiates it from the ColdCard?
Hey nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m, bitkey is pretty slick. Got home from the hospital and had it at my door today. Super easy setup. Bought $50 of bitcoin on coinbase; integration was super well done. Got my wife setup as a trusted backup person. Super easy and fast.
Having trouble getting it to see my electrum server inside a VM running umbrel, but that’s not relevant to 99% of users. But awesome that private electrum server is possible.
You guys hit it out of the park on this one.

Totally different sort of device. Think of it more in the category of Trezor/ledger but designed to work with ios/android out of the box.
The main feature is wallet recovery…it’s a multisig wallet where your bitkey has a key, the mobile app has a key, and their server has a key. Need ⅔ to spend. They store a copy of the mobile key encrypted to your device OS cloud account. Additionally, you can store encrypted copies of both bitkey key and mobile key with a trusted contact person…this lets you lose everything (bitkey and phone and cloud backup) and still recover (albeit with a security delay of 1 week, during which time you can cancel if you get the email/sms/push notifications of the recovery countdown).
It’s really well thought out.
Interesting. Thank you for the in depth explanation.
