Used my COLDCARD from Coinkite (npub1wu4…3vw0) today to sign a Partially Signed Bitcoin Transaction generated from Specter.

Build the transaction, save the PSBT to a MicroSD card on my desktop, plug that card into my COLDCARD, sign the transaction, plug that card back into my desktop and copy the transaction data to Specter, and then hit "Send".

My private keys never hit a live internet connection.

This always amazes me and takes less time than depositing a check at a branch bank.
