I have searched for this before and the best answer I got was that "there's no way of knowing when a private key corresponding to an address was generated. It can be done offline. It can be done years in the past". So,you can only know when the wallet first receive the first transaction,
a response in this article also support this.
I will be keenly waiting to see what others have to say too.
Thank you very much for the information and the link, my friend! You're super!
As mentioned above. There is no way to know when an address has been created. An address with a valid checksum = a valid address, whether someone generated it with a wallet before or not.
As for your second question regarding a tool that finds addresses with fresh transactions, I'm not aware of any. I even checked some on-chain intelligence services but there's nothing of that nature. Obviously, that's doable but you might need to code it yourself. I'm curious, what is it that you're trying to achieve here?
I watched some YouTube bloggers who tell guides how to find successful whale wallets in DEX, and poke their deals. Such whales have insider information. But when I really started checking the transactions of the token wallet, I saw that most of the first buyers use clean and new wallets. It's logical, why leave the story behind, so that people like me and other guys copy them. I thought that it would be possible to track the crypto wallets that have just been created, and monitor them. parse wallets from the first tranazktsii, map their addresses with the names of tokens and try to repeat their purchases. Maybe my questions are stupid and my ideas are naive.
