You can connect online to a daemon from wallet, for example
dero-wallet-cli.exe --daemon-host seeds.dero.io
that would not download the BLOCKCHAIN?
Please use derod.exe --add-exclusive-node 89.38.96.169:18090 --add-exclusive-node 89.38.97.110:18090
After that you can open dero-wallet-cli
I know that. But I would like to keep the wallet synchronized online, without downloading 2.6 GB
for example as for ETN (electroneum-wallet-cli.exe --daemon-host node.electroneum.hashvault.pro)
At this time there is no official perpetually updating seed for Dero.
Edit: Oh, I see what you're asking now. seeds.dero.io is just for a compressed data file and it's not a node you can connect to.
