🔸 Last week, hackers exploited a Coldcard firmware vulnerability in three waves, stealing nearly 1,600 BTC worth over $100 million
🔸 The vulnerability was hidden in a firmware update from March 2021, lying dormant for a full five years before it was discovered
🔸 Galaxy Research data shows about 7,300 addresses were affected, with many retail wallets drained
✅ The CEO of Swan remotely helped all night at a wedding in Paris—even stepping in to assist non-client users
✅ After this incident, users didn’t abandon self-custody; instead, they shifted to a “coordinated multi-sig” vault
✅ Core idea: If any single device is compromised, it still can’t move your coins
In plain terms, hardware wallets aren’t magic. A bomb planted five years ago in the firmware goes off today—no one could predict it.
But the endgame of self-custody isn’t an exchange; it’s a combination of multi-sig and cold storage.
What do you think—after something like this, would you still use a single hardware wallet? Let’s chat in the comments below👇
