Bitkey

Bitkey exclusively supports bitcoin.

Max Guise explains why: https://blossom.primal.net/3b4647f87b38c45c2c080df630b3c65766cd923eef8a6407a5185cfc665168de.mp4

Your key to self-custody. https://blossom.primal.net/fcaa11374114a47705b48627b980434b55cf375acc14dbd653673b12f463a8e9.png

Stay safe out there.

Bitkey is not affected by the reported Coldcard issue.

No action is needed for bitcoin held in your Bitkey wallet.

If you need to move funds now, use a wallet or service you know and trust rather than rushing a new self-custody setup.

Turns out most people use a bitcoin wallet the same way they'd use any wallet:

To hold their own money and spend it on their own terms.

Our new report with Global Digital Finance and Block, in partnership with TRM Labs and Coinbase, shows this in the data — and it's why we're building Bitkey for you:

True ownership of your money, no middleman holding your keys.

Report link below ↓

This is about as cheap as buying bitcoin gets.

Pick

in Bitkey and you'll pay zero trading fees and zero spread, so more of your money turns into sats.

Most wallets stop at setup. Bitkey is built for everything after.

Bitkey builds recovery, inheritance, and on-device verification in from the start.

No seed phrase. No subscription.

Self-custody used to mean “don’t make a mistake.” Bitkey assumes you will.

The new screen verifies recovery, inheritance, and security changes — not just transactions.

That’s what full protection actually looks like.

Meet the new Bitkey.

No seed phrase. Multisig by default. Built-in inheritance.

And now, with 100% more screen.

We have something to share with you all soon.

4.27.26

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.

https://bitkey.build/not-our-keys-not-our-business/

People come for the price. They stay for sovereignty. It shouldn’t be complicated.

Multisig at its finest. Built for real-world recovery.

https://blossom.primal.net/36dd56f0119d4924d47cc72fb68ca81a0b663576ff4c67f50941c1ed2b1bbdcd.png https://bitkey.world/

3 Keys. 2 required to transact. 0 single points of failure. Lose your phone? Covered. Lose your hardware? Covered. Lose both> Still covered.

That's multisig that's built for real life. Not perfect behavior.

Recovery contacts can help you get back into your wallet if you lose access without ever seeing your balance, your keys, or your transcation history. They verify it's you. That's it. Self-custody with a plan built in.

Modern tools for modern money. https://bitkey.world/ https://blossom.primal.net/abbd0f21a9532655b59cea8d7d546074777cd8fc8f506a2731b13aea439b3672.mp4

In single-sig self-custody, one exposed seed phrase ends the game. With Bitkey's 2-of-3 multisig, no single key can move your funds on its own.

Higher cost to attack. Lower risk for you. That's the design: https://bitkey.world/learning-hub/bitkey-basics/security/bitcoin-security#security-principles

Your address is your business. When you buy Bitkey, you can pick it up at a local retail location instead of having it shipped to your home. No shipping address.

No paper trail. Privacy starts at the point of purchase: https://bitkey.world/learning-hub/bitkey-basics/privacy/bitkey-privacy#pickup-points

There's usually a moment.

An exchange going down.

A withdrawal denied.

A headline that hits too close.

What was yours? What finally convinced you bitcoin self-custody wasn't optional?

"Tools like Bitkey make bitcoin so much more accessible to the average person." — Natalie Brunell. If bitcoin is for everyone, then the tools should be too.

Planning for the future shouldn't require a spreadsheet and a prayer.

With Bitkey, you can designate a beneficiary: no seed phrases, no instructions to lose. Your bitcoin, your terms. Generations from now.

https://bitkey.build/inheritance-is-live-heres-how-it-works/

Lost your phone or got a new one? Restoring your Bitkey wallet is simple.

Recovery shouldn't be a crisis. Here’s how:

Real life involves forgetting things, losing devices, and moments you didn't plan for.

Bitkey was designed for real life, not perfect behavior. https://bitkey.build/seedless-is-safer/

Security that ignores human fail. The strongest vault in the world is useless if real people can't use it safely. That's why we built Bitkey around how people actually.

https://bitkey.world/

Don’t trust. Verify. Privately.

The ethos hasn’t changed. The tools finally caught up.

https://bitkey.world/

If you plan to hold long term, your setup should be built for it.

https://bitkey.world/

We all say privacy matters.

Not in theory, but in practice.

What does that mean for you?

The longer you plan to hold bitcoin, the less you can afford a fragile setup.

If you’re reading this, stay close.

Resilient by design. https://blossom.primal.net/37bae9708de7f67dd01378090760238c5616a8c61dbba000fb14a92bb50b6a7a.mov https://bitkey.world/

Self-custody in the wild 🫡

Bitcoin is held for lifetimes. Build your setup like it.

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

Lose your phone and your hardware? You’re not locked out.

Bitkey Recovery Contacts help you regain access — without ever seeing your balance, keys, or transactions.

They verify it’s you. They can’t access your wallet.

Self-custody, with a recovery plan built in.

https://bitkey.world/learning-hub/bitkey-basics/general/how-it-works#bitkey-recovery-if-you-lose-your-phone-and-hardware

Spear phishing only needs panic to work.

And it only needs it to work once.

This story is based on a common real-world attack—one that hinges on what most wallets have: a seed phrase.

But Bitkey isn’t most wallets.

Multisig by default. No seed phrase to phish. Self-custody without the single point of failure.

Learn more: https://bitkey.build/bitkey-vs-a-spear-phishing-attack/

Recovery shouldn’t depend on perfection.

For too long, self-custody meant: lose your seed phrase, lose your bitcoin.

Bitkey changes that. Multisig security. No single point of failure.

https://bitkey.world

If bitcoin is the future of money, self-custody is how you actually own it.

Bitkey makes that step easier—secure by design, built for the long term. https://blossom.primal.net/d5e51e1dfffaa7df11a9239328eccdca74fad25cf7db499ae471c199a59398c8.mp4

Modern tools for modern money. When your bitcoin matters, the hardware should feel like it. bitkey.world

Self-custody shouldn’t end with you.

Bitkey makes bitcoin inheritance secure, intentional, and controlled — without seed phrases. https://bitkey.world/learning-hub/bitkey-basics/general/how-it-works#inheritance

“As long as it protects my money, that’s all I care about.”

Bitcoin News took Bitkey to the streets to talk privacy, bitcoin, and self-custody.

Buy privately. Pick up locally.

Self-custody shouldn’t require oversharing. https://bitkey.world/learning-hub/bitkey-basics/privacy/bitkey-privacy#pickup-points

For a long time, self-custody forced a tradeoff: privacy or recoverability.

That wasn’t a law of bitcoin — it was a limitation of the tools.

We think it’s time to move past that.

https://bitkey.build/chain-code-delegation-improving-privacy-in-collaborative-multisig/

When did bitcoin stop feeling like an investment and start feeling like a responsibility to you?

On Simply Bitcoin Bitkey Product Lead Jonathan explains how recovery contacts work — no keys shared, no balances exposed, just permissioned recovery built on trust.

When bitcoin self-custody meets thoughtful design.

Bitkey inheritance, explained.

Your bitcoin is never decrypted on our servers. Your beneficiary gets nothing until the claim is complete. A 6-month delay protects against fraud.

Here’s a technical deep dive into how it works 👇

https://bitkey.build/bitkeys-inheritance-feature-a-technical-deep-dive/

What if Bitkey goes down? Your bitcoin doesn’t.

Bitkey is built so you can move your funds independently, even without our app or servers.

Seed phrases were meant to help with recovery.

Over time, they became the easiest way for scammers to steal bitcoin.

By design, Bitkey removes seed phrases entirely— eliminating the most common attack vector in self-custody.

Locked out doesn’t have to mean starting over.

If your fingerprint stops working, you can recover access to your Bitkey without replacing your device — with a built-in security delay so nothing happens instantly and you stay in control the whole time.

Self-custody shouldn’t require giving up your privacy.

With Chain Code Delegation, Bitkey enables collaborative multisig without exposing balances or transaction history.

Not our keys. Not our business.

https://blossom.primal.net/63e283e781dd0d8aa37606768c1d77c50b639bf3e2d945315073c9abaa73bd9e.jpg https://bitkey.build/not-our-keys-not-our-business/

Private by default. Not a setting.

Anyone onboarding to Bitkey today gets a wallet we’ve provably never seen.

Existing users can upgrade to get there too — new wallet, new descriptor, full privacy.

Jonathan breaks this down further with Simply Bitcoin

No distractions. Just bitcoin.

Bitkey doesn’t use seed phrases.

Not because recovery doesn’t matter, but because relying on one fragile backup creates a single point of failure.

Self-custody should survive real life.

Why we built it this way ↓

https://bitkey.world/learning-hub/bitkey-basics/general/how-it-works#why-bitkey-doesnt-have-a-seed-phrase

Hardware wallets are essential. But they’re not the full answer to self-custody.

Secure signing ≠ safe ownership.

True self-custody has to account for loss, theft, coercion, inheritance — and real life.

Our Product Lead, Jonathan breaks down why hardware alone isn’t enough, and what it takes to solve the whole custody problem 👇

https://bitkey.build/hardware-wallets-are-not-enough/

Collaborative multisig has always come with a privacy tradeoff.

Chain Code Delegation removes it.

Cosigners can help with recovery and policy enforcement—without seeing balances or transaction history.

That’s a privacy win for the entire bitcoin ecosystem.

Self-custody doesn’t have to mean “you’re on your own.”

Bitkey is built around: – Multi-layered security – Open-source transparency – 2-of-3 multisig (no single key = no single failure) – Systems designed for real humans, not just experts

https://bitkey.world/learning-hub/bitkey-basics/security/bitcoin-security#security-principles

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 → https://bitkey.build/seedless-is-safer/ https://blossom.primal.net/54bd2358e72b81e93b54cbc5c5494eeb136f227dedeeab9111f1d47084906862.png

Collaborative custody shouldn’t come at the cost of privacy.

Chain Code Delegation removes a long-standing tradeoff in multisig wallets: safety or privacy.

With it, cosigners can help with recovery or policy enforcement without seeing your balances or transaction history.

This is already live in Bitkey — and it’s a meaningful privacy upgrade for bitcoin self-custody.

https://bitkey.build/chain-code-delegation-improving-privacy-in-collaborative-multisig/

How much bitcoin has been lost due to bitcoin mismanagement?

Lost seeds. Phishing. Fires. Simple mistakes.

That's why we removed the seed from the equation.

One key. One device. No export. Multisig-based recovery.

Security that ignores human behavior isn’t security.

Design matters.

What does “safety” actually mean in bitcoin self-custody?

Bitkey Product Lead Jonathan Pollack explains why security alone isn’t enough — and how usability and privacy are just as critical to keeping your bitcoin safe.

The true test of self-custody isn’t just whether or not you hold your own keys. It’s whether or not you can protect them from loss, theft, coercion, seizure, and death, and still be able to make transactions when you need to, without a third party intermediary.

What do you mean, 'there's no seed phrase?' Most wallets give you one recovery option: your seed phrase.

We built Bitkey with three — no single point of failure, no seed to steal.

Here’s how our 2-of-3 recovery model works in real life:

https://bitkey.build/what-do-you-mean-theres-no-seed-phrase/

We’re not anti-seed. We’re pro-progress.
