Friendly reminder: the issue with Coldcard was the entropy source used to generate seed phrases. Certain firmware versions produced seeds with insufficient entropy, making them easier to brute-force. If you generated your seed on an affected firmware and then imported that same seed into another hardware wallet, your funds may still be at risk. Generate a brand new seed phrase, move your funds to it, use a BIP39 passphrase, and ideally store your bitcoin in a multisig setup
