question:

I set up my #COLDCARD Mk4 w/ #nunchuk via #NFC - is that considered #airgapped?

or must the provisioning be signed on SD card via #PSBT to be considered truly air-gapped?

asking for a friend 🙃🤙

PSBT via SDcard, NFC, and camera read QR code are all valid forms of air gap.

SD Card is the only one that allows air gapping discretely over large distances.

“over long distance” - yes! this is true, totally did not consider that distinguishing factor…
