Coldcard Raises Security Standards: 65 Keystrokes After Seed Exploit – Yet Funds Remain at Risk

That was a bit of a shock when I heard that Coldcard had to respond to a seed exploit with an update. After all, Coldcard is one of the most trusted hardware wallets out there—you certainly don’t want something like this to happen.
Now, with firmware version 5.6.1 (or 1.5.1Q), the company has introduced stricter security checks. When creating a new wallet, users must now perform 65 deliberate keystrokes to confirm that the seed phrase is genuinely their own. Sounds good at first, right? More interaction for better security—makes sense.
BUT—here’s where it gets tricky. While the update protects against future attacks, wallets already created with an affected version remain vulnerable. The



seed phrase could still be compromised despite all security measures. Coldcard strongly advises users to transfer their funds to a new wallet—and that really is the only secure solution.
I think this just goes to show: even the best solutions aren’t flawless. The crypto world is a constant game of cat and mouse, and hardware wallets like Coldcard do their best to stay ahead. Still, it’s always wise to remain vigilant and regularly check if everything is still secure.
To all Coldcard users: absolutely check your firmware and act quickly if you’ve used affected versions. Better safe than sorry. And remember—even if those 65 keystrokes are annoying, they’re a small price for better security.
