I lost a lot of money on this but as the previous messages said, the chain still works. In case you didn't know it, Sunpool has been keeping it going. Here's what you might need to know if you still want to send & receive XGM or GRIMM...
If you see a red light, this will turn it green:
1) open the wallet in Light Mode
2) click on SETTINGS (on left menu)
3) where it says ip:port, enter... defis.sunpool.top:10000
Now you should be connected and you will see the green online indicator (go to DASHBOARD).
You can do this same process with Grimm but use this in SETTINGS:
grimm.sunpool.top:10000
