3 keys. 1 wallet. 0 single points of failure.

Seed phrases solved one problem and created another. They made recovery possible — but turned everyday users into security engineers, disaster planners, and inheritance experts. Over a lifetime, perfect behavior isn’t realistic. Security systems should be built for that reality. Seedless is safer. Here’s why →

"We know there’s not one right way to self-custody. And for some people, seed phrases still make sense. But if bitcoin is going to be the money of the future, it needs to fit into the lives of the people who will use it." That's why we built Bitkey.

Beyond the seed phrase: Why we built Bitkey

Night owls, we didn’t forget about you. Here’s a sight for those sore eyes—dark mode is now live in the Bitkey app. Thanks for all your patience and enjoy the new look.

One year in, and we’re just getting started. From our worldwide launch to being named one of @TIME’s Best Inventions, our first year’s been big. We’re excited about the momentum and looking forward to a world where self-custody is the easiest way to hold your bitcoin. Thanks for all your support and feedback this year. Keep it coming, we’ll keep building.

If you don’t hold your own keys, you don’t own bitcoin. Self-custody isn’t just an option—it’s the only way to truly own your wealth. Bitkey is here to make self-custody more accessible, without compromise. Let’s build a future where everyone controls their own money.
