Exposure comes from what you broadcast and what leaks about you. You control the first, but not the second. In 2025, a French tax officer was caught selling crypto holders' home addresses and capital gains to criminal gangs. We don't know how long the data had been moving before she was caught, and crews can plan for days to months before acting. Over that same window, the France case reports we found went from roughly one a year between 2017 and 2024, to 21 in total for 2025. Comparing January to June only, France went from 10 cases in 2025 to 31 in 2026. A 210% jump. Assume you're already on a list and build the habits that make you harder to reach regardless.

A wrench attack runs on one assumption: that one person, under enough pressure, can move everything. Multisig takes that apart. No single signer can send the funds, so no single person can be forced to. A time-locked key cannot sign yet, so there is nothing in it to take today. None of this makes you less of a target, but it removes the single point they can break. On July 29, we walk through building custody with no single point of coercion.

If your safety app got breached tomorrow, what would the attacker walk away with? For most, a year of your movements, your contacts, your daily pattern. For Gart, nothing. No KYC, no central server, no location history. Nothing to seize and nothing to sell. On August 5 we'll tell you how that works, and why we built it that way. Webinar: the Gart app. Free session, live Q&A, with our founder and the team who built it. August 5, 2 PM UTC. Limited spots.

A Russian restaurant owner in Uluwatu, Bali was taken on the night of July 2 as he rode home from his own restaurant. Two masked men blocked his motorcycle, cuffed him with plastic restraints, covered his head, and drove him to a two-story building. He was punched and kicked for close to 30 hours until he gave up the password to his crypto account. The stop happened at a junction on that route, around 9:35 PM, on a deserted stretch with almost no camera coverage. They took his Xiaomi phone at the roadside. His villa key was sitting on the motorcycle's dashboard, so they used it to walk into his villa and take a second phone, the one he used to reach his crypto funds. No arrests so far. An estimated $4.9M to $5M was taken. They let him out in front of Udayana University Hospital in Jimbaran at 4 AM on July 4. Full report:

Picture the person you'd leave your coins to trying to reach them without you in the room. They don't know if the seed is on paper or steel, whether it's whole or split, or which drawer even holds the right device. Everything you did to keep it safe from a stranger now works against the one person you meant to have it. Session 4 of our free Digital Security Webinar Series works through it: Backup & Inheritance Strategies In partnership with and hosted by the Sound Money Solutions team, led by @Max Hillebrand. What we'll cover: - Redundancy that adds copies without adding single points of failure - Where backups live, and who can reach them - An inheritance path that triggers without exposing keys early - Recovery that holds up July 15th.

The most planned attacks don't start with a break-in. They start with a relationship. Someone spends months as a real business partner, earns your trust, then uses it to move you somewhere they control. No public wallet, no leaked address. The trust is the way in. On June 29, two women were lured to Pakistan by a business partner they'd worked with for eight months. Upon arrival they were kidnapped, held at gunpoint, assaulted, and asked to pay a $1.5 million ransom. One of them reached her father, who alerted police. They were rescued within about two hours.

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.

Digital Security Series, Session 3. An Introduction to Gart's Remote Training.

"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. Download for free:

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:

Gart Stats - Database of Physical Attacks Involving Cryptocurrency Since 2014

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. #physicalsecurity #opsec #news #bitcoin

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 npub1klkk3vrzme455yh9rl2jshq7rc8dpegj3ndf82c3ks2sk40dxt7qulx3vt 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?

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. Link:

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. Full blog:
