Another month. Another cycle of noise. Self-custody is still the answer. And bitcoin is still bitcoin. Conviction compounds. Q2 starts tomorrow. Stay sovereign.

We didn't build Chain Code Delegation to keep it. We built it as an open bitcoin improvement proposal so any wallet can implement it. Privacy in collaborative multisig should be the standard.

"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. https://bitkey.build/beyond-the-seed-phrase-why-we-built-bitkey/

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.
