Quick question... is a signed message required for each tx, Or can a single signature be valid for example 2 weeks?
Your signature just proves you are the owner of your wallet.
I think this is important and I really need to do this. Thanks for let me know something like this.
I just read the first post on this thread and still learning step by step.
Anybody know, is there any case related to this prevention tips which can prove that an address belong to me. I mean is there any cases that successfully recovered from hacking since he did this sign a message? Then if any, how about the balance inside that wallet? Is it safe or this just will prove the wallet owner so far and can not prevent from its balance robbery? (sorry, this is very newbie question, I understand it)
The signature can not prevent you from hacker. If you lose your private key, you should create a new wallet.
