- We need this private key to make transaction in a normal wallet. But it never stated that you're going to give it. Only the public key is needed.
My private keys (BTC) are in the cold wallet. I will never put them into Internet connected stuff. Sorry for that.
I really doubt whether atomic swap is VPN -friendly.
Currently AS is in testnet only. So you have to use testnet addresses/keys anyway. When it goes mainnet: 1) Create a hot wallet for AS 2) Use virtual machines to connect to internet. Qubes OS is great for this. It needs a bit of learning at first but i think most can manage.
