Please don't worry. function swapProxyTokens is included in the Contract Source Code. My advice is to wait patiently for the Proxy team with an official instruction how this function can be called by old Proxy holders.

You can read the Verified Contract Source Code of ePRX here. Scroll down to line 255 to see the function.

Completely agree with you.. we seems just stupid idiots if we own old PRXY tokens.. the team focus their time only on ebtc holders ( s*it scamcoin useless, no sense token) and they are ignoring us, old prxy holders.
Team, stop discussing with scam projects and focus on old investors!

This would be the first wallet I need to open a port or do a port forward to in order to stake. That would be a bad program design. Why would I need open incoming ports if there are master nodes? There should be something in the logs if the wallet needed open ports that it doesn't have? I will have a look.
Maybe the developer could provide an updated instruction for staking with the new wallet (I don't even understand the separation of zSUB1X and Sub1x, do I own old Sub1x coins in the new wallet?). In the old wallet it worked out of the box.

I was already forced to restart the wallet, nothing changed since then. This is how it looks like for days:

Says: "Staking not active"

How to stake/mint with the zSUB1X wallet? I received my coins 28.02.2018 and it has more then 5000 confirmations but it doesn't seem to start staking/minting. What's wrong?
