BitBox

No exchange is too big to be hacked.

“What was that payment for again?” 🤔

Pizza with friends. A birthday gift. That thing you were sure you’d remember.

Add notes to your bitcoin transactions in the BitBoxApp, then find what you’re looking for with a simple search.

A few words today. Less guesswork tomorrow.

Your hardware wallet doesn't need to come with you to pay for a coffee.

Lightning is now in the BitBoxApp. Public beta, for every BitBox user.

One backup. Both wallets.

Our preliminary review of the phishing mail that was sent out to our newsletter subscribers about an hour ago found that it is very likely that our newsletter provider got compromised.

Multiple other Bitcoin companies got targeted as well, and it appears that we all share the same newsletter provider.

We sent out a phishing warning to all our newsletter subscribers, contacted the provider and reported the phishing domains. Most of the phishing links appear to have been taken down already.

We are still actively investigating this situation and will update you once we know more.

There is currently a phishing email going around that's pretending to come from us.

Please do not follow the instructions in the email.

We are currently investigating.

Hi.

Every hardware wallet we sell can run the current firmware.

Bye.

We just released the Dixence security update.

During our internal audits, we were able to discover and fix multiple security issues in the BitBox firmware.

We recommend our users to update their BitBoxApp and device firmware through the BitBoxApp settings.

https://blog.bitbox.swiss/en/bitbox-08-2026-dixence-update/

As a hardware wallet user, one of the best ways to stay secure is to keep your wallet firmware up to date.

With AI models only getting better at finding and fixing bugs, expect regular updates for your hardware wallets in the near future.

https://blog.bitbox.swiss/en/firmware-updates-in-the-age-of-ai-staying-up-to-date-matters-more-than-ever/

If you own a hardware wallet, you probably spent the last few days wondering what you're actually able to check for yourself.

Short answer: more than you'd think.

Here are the questions worth asking any manufacturer (us included):

• Where does the randomness come from?

Every wallet begins as one large random number. If that number is predictable, nothing built on top of it holds.

Ask how many independent sources of entropy the device combines and what happens if one of them turns out to be weak.

• Can I check that the firmware on my device matches the published code?

Reproducible builds let you verify the binary you're running was built from the source you can read.

Worth being precise: that proves the binary matches the source. It does not prove the source is correct.

• Who approves a change before it reaches my device?

Ask whether one person can ship firmware alone, or whether every change needs a second set of eyes.

This is unglamorous and it is where most of the real security lives.

• What happens when they find a bug?

Every manufacturer ships bugs. The question is what the process looks like afterwards.

Ask about the bug bounty. Ask how quickly users were told the last time something was found.

OUR ANSWERS

• The BitBox generates your wallet from five independent sources of entropy: Physical noise from the secure chip, physical noise from the MCU, randomness provided by the host device, a static random number set in the factory and your own device password.

The benefit of mixing entropy: Redundancy. All but one source can be compromised and your seed would still be secure.

• The BitBox firmware supports reproducible builds you can independently verify yourself (link in the comments)

That way you know the firmware you install matches the public source code.

However, it is generally very difficult to verify what code is actually executed on-device.

• All change requests to the BitBox firmware require an approved review by a maintainer to be merged.

• The BitBoxApp and BitBox firmware are fully open-source and part of our bug bounty program (link in the comments )

Bug reports are financially rewarded depending on their severity, encouraging security researchers to actually take a thorough look.

• We announce security updates publically on our channels, including detailed information on the vulnerability and how it might have affected users.

Wallets created on a BitBox are not affected by the Coldcard RNG vulnerability. A BitBox seed combines five independent entropy sources. One weak source does not compromise the result.

BitBox is not affected by the recent RNG vulnerability that affected one of our competitors.

More details coming soon.

Stay hydrated

Going somewhere? 🏝️

With the BitBox02 Nova you manage your savings straight from your phone, even on vacation;)

Sale season has begun

You can't control the market. You can own your keys.

The BitBox02 does something that other wallets don’t: it backs itself up. To a microSD card. In 60 seconds. 👀

Price, wars, markets: not your call. Private keys, your stack, when you sell: all yours.

That's Bitcoin.

The 20 millionth bitcoin just got mined. 95% of all the bitcoin that will ever exist is now in circulation. The last 1 million will take until 2140.

Self-custody, so you make sure the ones you have are actually yours.

The BitBox is small, discreet, and looks like a boring piece of office tech.

It doesn’t attract unwanted attention when you’re on the move.

Pack it, cross borders, and keep your bitcoin safe without standing out.

Your personal Swiss vault.

The hardest part of self-custody is the setup anxiety.

That’s why the BitBox uses a microSD card. It creates an instant, verified backup so you can secure your keys now and write down the 24 words later, with a clear head.

Loved by begginers (and the pros helping them) ❤️

Plug directly into your phone and unlock Swiss Bitcoin security. It's that simple.

Cold storage is no longer a desk job.

We built the BitBox02 Nova to work where you work. Whether that's a hardened Linux setup or the iPhone in your pocket.

✅ Full compatibility with iOS, Android, and desktop.

The same Swiss 🇨🇭 security, on every device you own.

We spent the last weekend at CES, the most powerful tech event in the world in Las Vegas.

We were surrounded by 100,000 people. It was our biggest conference so far.

The best part was having one-on-one conversations about ownership with people taking their first steps into Bitcoin.

We love watching someone finally realize that they can be their own bank.

That sudden clarity. You can see it happen in real-time: the "click." The moment someone stops looking at the Bitcoin price and starts thinking about the keys.

Thanks to everyone who stopped by, and to all of you supporting us from home. ❤️

Glad to be heading home. Back to the office. Back to building.

We upgraded the BitBox02 Nova with a tempered glass screen for maximum resilience and durability.

🇨🇭 Swiss-made quality that works seamlessly across all your desktop and mobile devices, including iPhone.

“Bitcoin is not for spending.”

Alright, tell that to the people who can now buy Amazon and grocery gift cards straight from their BitBox.

We’ve integrated

into the BitBoxApp 🫶

Your groceries didn’t change. Your money did.

GM. We’re not the same

Whisper = secure Bluetooth for the BitBox02 Nova.

🚀 Mobile self-custody on iPhone & iPad, without trade-offs:

• Hardware-isolated BLE • Authenticated pairing + double E2E • Reduced range + private addresses • USB-first, open source

Some ideas refuse to die.

For us, it's a no-brainer: wallet first. If you want your bike to be safe, you get a solid lock first.

But we get it, some see it the other way around. What do you think?

The new BitBox02 Nova isn’t just compatible with iPhone, iPad, and Android. It’s our most premium device yet.

Have you tried it already?

https://bitbox.swiss/bitbox02/nova/

You can now grab your BitBox while doing your groceries at REWE Teupe in Dortmund, Germany.

Right next to the fridges. Because cold storage belongs in cold places.

Being a Bitcoiner isn’t easy. Being free never is.

Why manage 5 backups when one seed gives you everything?

With BIP-85, your BitBox backup becomes the master key to your entire digital life. Smarter self-custody starts here:

Ever try stopping a leak with duct tape? That’s fiat policy in a nutshell. Bitcoin, though? It’s water. Let that sink in.

1. It’s open source. Nobody owns water, yet companies bottle it, sell it and build services around it. Same with Bitcoin: the code is free, but people develop businesses, tools, and entire industries on top of it.

2. It can’t be 'printed' like paper money, it has to be found, collected and preserved.

3. It flows freely… until someone tries to block it. Water finds a way. So does Bitcoin: around bans, around banks, across borders.

4. There’s no second best. Coca-Cola tastes good, but water keeps you alive. Shiny altcoins might look interesting but Bitcoin is the essential one.

5. It breaks through slowly but surely. Dripping water carves stone. Bitcoin is relentless: quiet, patient, unstoppable.

6. It’s transparent, yet can be private. Everyone can see the river (the blockchain), but not what’s inside your bottle (your keys).

7. You wouldn’t trust someone else to store your water... so why trust them with your bitcoin? Self-custody or nothing.

Funny, huh? Once you see this comparison it’s hard to unsee. What would you add?

Two mindsets. Two futures.

One is built on scarcity, math, and freedom. The other on trust, inflation, and illusion.

Choose wisely.

Today, August 1st, we celebrate both Swiss National Day and Bitcoin Independence Day with a limited drop built for true sovereignty:

In less than ten days, we’re heading to

, Europe’s biggest Bitcoin-only gathering.

We’ll be there with a special announcement 👀

And of course: whitepaper booklets, merch, gifts, and plenty of updates to share.

If you're coming, come say hi at our booth. we’d love to meet you!

See you in Prague! 🚀

People who say ‘Bitcoin self-custody is too risky’ live in a world where governments freeze accounts with a tweet.

🧠 Start thinking in Bitcoin.

Trustless money requires trust in yourself. That’s the real shift.

You just bought bitcoin? Congrats. Now do… nothing.

Ok, if you’re excited and want to check the price 10 times a day, fine. But here’s the truth: it doesn’t matter if it goes up or down this week. Your bitcoin should be like a digital piggy bank: untouchable.

You didn’t buy it to get rich tomorrow. You bought it to protect your time, your energy, your future.

Don’t trade it. Don’t stress. Don’t try to outsmart it.

Just hold. Let time do the work.

Access isn’t ownership.

Storing data on the blockchain: How does OP_RETURN actually work?

Bitcoin doesn’t fix everything, but it respects your time.

If you work a regular job: 40 hours/week × 45 weeks = 1,800 hours/year 2% inflation = 36 hours gone

Not because you worked less, but because your salary quietly lost value…

Happy Labor Day.

Bitcoin shows you where your money is. We show you how we protect it.

Just because it’s called “money” doesn’t mean it works the same.

A great product means nothing without great service. 4 years later, we still have your back ❤️

Bitcoin sits at the intersection of money and time.

It’s not just a new form of payment.

It’s a tool to store the work you’ve done, the time you’ve spent, and the value you’ve created.

No need to trust banks or governments. No need to worry about someone inflating your savings away.

When money is based on math, not politics, you can finally plan long-term, with confidence.

That’s what makes it different.

Privacy isn’t just a feature. It’s a principle. Your hardware wallet should know as much about you as your toaster: absolutely nothing.

A real Bitcoiner doesn’t say ‘I love you.’ They say ‘Is your seed phrase backed up properly?’

Printing more money to fight inflation is like eating more donuts to lose weight. Sounds nice, doesn’t work.

Happy Father’s Day to all the dads teaching their kids the important things in life: self-reliance, patience, and why you should never leave your bitcoin on an exchange ❤️

Exchanges don’t ‘hold’ your Bitcoin. They ‘owe’ you Bitcoin. And there’s a huge difference.

Want to help your family take control of their bitcoin safely? The BitBox02 is secure, simple to use, and beginner-friendly. So easy you can confidently recommend it to your parents.

Read why it's the perfect hardware wallet for families:

Self custody is simple math: Keys + you = bitcoin Keys + someone else = maybe bitcoin

X down again? Centralized platforms always find a way to fail. Bitcoin doesn’t. Nostr doesn’t. Neither does your self-custody with a BitBox02. 🚀

A hardware wallet doesn’t do KYC, doesn’t freeze your funds, and doesn’t suddenly change its ‘terms of service.’ Feels like a good time to own one.

Bitcoiners debate, politicians argue, and the market swings. I just sit here, cold and quiet, holding your keys like always 🥹

Bitcoin is useless.

If prices in your country are going down. If your salary increases every month. If you can send money globally for free. If your savings grow faster than inflation. If your bank never blocks your transactions. If governments never freeze accounts. If no currency has ever collapsed. If financial institutions always act in your best interest.

Then yes, Bitcoin is useless.

Breaking news: the government asked me for all your data. I was about to comply… then I remembered, I don’t have any. I’m a hardware wallet.

You can write down your 12 or 24 words today, or spend the rest of your life explaining how you ‘once had Bitcoin’.
