🧵Guide for @COLDCARDwallet + @SpecterWallet

Setting up Coldcard with Specter Desktop in 10 steps (or less)

1/ Click "Add new device" button on the left sidebar

2/ Select Coldcard as the device type

3/ Now you can either go with the airgapped option using SD Card or via USB with the Coldcard connected to the computer.

Either:
- Airgapped: Click "Upload from SD Card"
- USB: Click "Get via USB", wait for about 30 seconds until the loaders finish, then skip over to step #5.

4/ Select the file you exported from the Coldcard to the SD Card. Then click "Choose".

(to export - on your Coldcard, select Advanced -> MicroSD Card -> Export Wallet -> Generic JSON. When asked for account, select acount number (default is 0) and confirm the export.)

5/ You should now see some XPUBs appeared in the table.
Name the device (i.e. "My Coldcard") and click "Add device" at the bottom.

6/ You should see a popup titled "New device was added successfully!".
You can click now either on the "Add new wallet" button on the left sidebar; or on the "Create wallet" in the popup (the latter will take you to step #9, Specter will automatically do steps 7 + 8 for you).

7/ After clicking on the "Add new wallet" button on the left sidebar, click on the "Single key wallet" option.

8/ Click on the Coldcard device you just added (you'll identify it by the name you gave it on step #5).

9/ Name the wallet, choose whatever address type you prefer (Nested/ Segwit), select whatever you would like to rescan for existing funds, and then click "Create wallet" at the bottom.

10/ You should see a Pacman loading screen... then congrats! Your air-gapped Coldcard is now ready to use with your @SpecterWallet!
You should see the following confirmation popup:
