Attention Local Coldcard Users:
A critical vulnerability has been disclosed regarding seed phrases generated directly on Coldcard devices. If you generated your seed phrase on-device, your funds should be migrated to a newly generated setup. Setups utilizing dice rolls or external generation are unaffected.
A private, self-guided demonstration session is being held to educate anyone needing technical guidance on air-gapped key migration:
* Where: Kentwood Library — Study Room 212
* When: August 4, 6:00 PM – 7:30 PM
Privacy & Opsec Assurances:
* Completely anonymous: No check-in, names, or sign-ups.
* Zero disclosure: You do not need to show your screen, seeds, or balances to anyone.
* Flexible: You can bring hardware to work through the process locally, or simply observe the step-by-step walk-through and perform the migration at home.
