Just consolidated some utxos in my "deep freeze" multisig wallet. Partially signed it using a Coldcard via Sparrow, picked up the PSBT on my phone by scanning a QR code and added the second signature from my Tapsigner using Nunchuk, before airdropping the PSBT back to my desktop for broadcasting. Nice to "exercise" my cold storage wallet every once in a while to reassure myself everything still works. #bitcoin
