Recent Notes

Most people pick a hardware signer like they pick a router. Brand, price, done.

But the right signer depends on what you're defending against.

A remote attacker, a border crossing, someone at your door, an heir who has to recover it without you. Different threats call for different tools, and most setups never make that choice on purpose.

Join our free Cold Storage & Hardware Signers session, in partnership with and hosted by the Sound Money Solutions team, led by @Max Hillebrand.

Tomorrow, July 1st.
Limited seats.

"Not your keys, not your coins."
Every holder knows it. Almost everyone stops there.

You hardened the wallet, air-gapped the signer, split the multisig into three. All of it protects the coins.

None of it protects you.

Under a real threat, the coins follow the person. The last layer of self-custody isn't a device or a seed. It's you, and the people you'd protect.

Secure the keys. Then secure the one thing you can't restore from a backup.



Here's where to start:

The Personal Opsec Checklist, a practical self-assessment of the gaps most people miss.

It's a sample from our extended version, distributed exclusively at Gart Trainings.

June 11, Vitória, Brazil 🇧🇷

A 30-year-old crypto investor is dragged out of his Porsche in broad daylight.

Eight men, three cars, under a minute. The first thing they demand is a crypto transfer. They already knew what he held, because his public profile told them: high-risk crypto and forex trader, 80,000+ followers.



They knew his asset class and his routine before they moved. The recon was his own profile. The ambush was just the last step.

Full case in our database: https://stats.gart.io/#attack-456

Audit your own footprint:

1. Does any public profile name your asset class or signal liquid wealth?

2. Can someone rebuild your week from your posts: gym, office, school, run, the same coffee?

3. Does anything online tie you to your home, your car, or your family?

You don't need an audience to get selected.
You need a profile that names what you hold.

The speed of information extraction is accelerating; correlating public profiles with real-world events reveals a chillingly efficient market.

Interesting timing: June 11th saw a 3.5% Bitcoin price drop within a 5-hour window. Was this incident a market trigger or a coincidence?

A backup you've never restored from is a guess, not a backup.

Most people who self-custody wrote the seed down once and never tested it. The same blind spot shows up in how the keys were generated, how signing stays off the internet, and whether the signer you picked fits the threat you're defending against.

Session 3 of our free Digital Security Webinar Series works through it. In partnership with and hosted by the Sound Money Solutions team, led by @Max

What we'll cover:
- Choosing a signer for your threat model
- Air-gapped signing and wallet separation
- Initialization and entropy
- Recovery that holds up

When did you last restore from a backup instead of just rereading the words?

July 1st. Limited seats.

The highest-value security move costs nothing: an honest look at the gaps you already have.

Our free Personal Opsec Checklist is a structured self-assessment across six areas: public records, digital footprint, personal space, routines, self-defense, and situational readiness.

You rate your own risk in each, then prioritize what to work on first.

A sample from our extended version, distributed exclusively at Gart Training sessions.

What does the safety app on your phone know about you?

Gart's answer: nothing. By design.

1. No background tracking. The alert button stays silent until you trigger it. No background location.

2. End-to-end encrypted. Alert content and chat use NIP-44. We can't read them, and neither can the relays.

3. Nothing to hand over. No identity, contacts, or location stored. You can't leak what was never collected.

4. Publicly verifiable. The live alert stream is public. We'd rather you check than trust us.

We wrote exactly how it works.

A password keeps people out. Access control decides who you let back in.

Join us this Wednesday for a free Gart webinar with @Max Hillebrand and the Sound Money Solutions team: Password Management & Access Control. Live session with a Q&A.

Last week, at @BTC Prague we only scratched the surface of personal security. This is where we go deeper.

Besides your password, what else stands between someone and your accounts?

How is location tracked and shared selectively?
Gart profile picture
Location is not tracked in the traditional sense (the app is not fetching constant updates).

When you hit the button, your device takes the GPS, encrypts together with your custom alert message and sends as kind 694.

the event is published to ~6 relays, while your Watcher's devices are listening to your 694 alerts, and when they find one, they decrypt its contents with a shared finder Key (shared within your Group of watchers).

Gart for Android is live on Zapstore.

It took longer than we estimated, but it does what we set out to achieve.

Privacy-first emergency response for people who keep a low profile.

Add your trusted contacts. Prepare your alert message in advance. One tap to send alert. Peer-to-peer, end-to-end encrypted, no tracking. The alert button is dormant until you trigger it. Only the people you chose receive the alert and your instructions.



Gart Beta Testers who join before Jun 15, lock in early-adopter perks for life.

Why build another safety app?
Because the popular ones watch you, sell you, or can be tricked into handing you over.

One has 98 million users and sold their location to data brokers within 20 minutes of collecting it.

For what purpose you use cookies on your website? Was it strictly necessary? Just curious, strange to see it there considering your app specifics.
