puzzle 66 was found by a newbie and stolen by bots.
Now Mara has been discovered. But there are not many people who know how to use it. So helping people
If anyone knows how to use Mara. A detailed explanation would be helpful. Maybe someone lucky will find it, don't let the bots lose it.
1- First, you perform the transaction here. You take raw TX out.

It's that simple.

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.
