Thanks for the info. but according to the link you gave, won't the publickey be exposed when I sign raw tx in my electrum? in this way, aren't we actually broadcasting the transaction? Also, I didn't see such a step in the new version electrum. the question I asked may seem simple and funny to you, but I am trying to understand how people like me who don't know much can achieve this.
If you sign, the publickey is not released. If you say PUBLISH, the transfer starts and the PUBLICKEY is released.
In the new versions, PUBLISH does not come out without SIGNING. I know that.
