Self-custody should feel like a natural part of owning bitcoin. With our new auto-withdraw feature, eligible @CashApp customers can buy BTC in Cash App and have it automatically moved to Bitkey for safekeeping. Set it once, keep stacking, and safeguard your BTC with Bitkey.

Recent reports describe modified Ledger devices that captured seed phrases as they were sent to the screen. Learn why Bitkey’s seedless design leaves no recovery words for this attack to capture, and how separately held keys help protect your bitcoin.

Always aiming to improve the experience.
when i got the beta Bitkey, i started using it right away then my dad's bitcoin stack grew to the point where self custody made sense for him, so i handed it to him, since it was super easy to use and secure then i got a second Bitkey and created a new account on a different phone for my own stack then i got a third Bitkey, at this point i'm basically a hardware wallet hoarder but i have nowhere left to create an account right now, each Bitkey account needs its own phone soon you'll be able to have multiple accounts on one phone, which will make it easier to manage my ₿ and my family's without also hoarding phones
