bitaddress.org and walletgenerator.net don't support my coin. my wallet will make QR's for public addresses, but not private keys.

between steps 3-5: is copying the tx through these steps a possible compromising vector?

is the private-key part of steps 1-5 an air-gapped computer vs. the public-key/internet-connected part a node?

how do they communicate? QR codes? usb drives?

I can see how you'd do all that with electrum but there isn't an electrum version for my coin.

I see the BIP38 encryption thing at bitaddress, but that works only for BTC addr's.
