hi-
can i find a wallet somewhere? v0.8.6.2 seems to be outdated ...
*"errors" : "URGENT: Alert key compromised, upgrade required"
That is the current version in use by most nodes.
Never mind about the alert key error, it just means the alert key has been disabled by the owner so that it can't be abused in the future.
BTC and many other chains did this before.
Check below post to get a more verbatim explanation of what this error means:
