I agree about polo not being needed. My account trading access was compromised late may and all value transfered out and Im left with qora. Totally polo's fault as my cpu wasnt hacked else they couldve withdrawn, my fault for trusting polo and not 2fa.
Anyway,
If I want to trade ltc to kmd using the dex, it sounds like I should be using a client node. Do I need to dl both ltc and kmd chain? Or is this something basilisk can do and I won't need to dl either?
I just coded the client mode forwarding, so other than the extra hops and the increased chance of a trade being incomplete, client mode should work fine.
The atomic swap protocol is able to handle either party disconnecting at any stage of the protocol, with most cases able to just pick up where it left off when reconnecting. There are a few cases where you will have to wait for a few hours to recover funds, but in most of those cases you get a 12% bonus.
For most of the trades for most of the people most of the time, after a few coin confirmations, the trade will be completed.
And then if I don't want to have the native chains I would use the shapeshift feature that Im assuming is some smart address where I send my komodo and it deposits litecoin in my litecoin address if that is my selected trade.
That might be the easiest method come to think of it.
