I recently searched for an address and some sources told me that my address is invalid but I was able to sign a message with that address using Electrum, if my address was invalid Electrum would have notified me right?

What did the address begin with? If it was a bc1 address then the error was with the website, if it was with anything else the error might be yours.

Above address is what I'm talking about.

If you are able to sign a meassage, it means you control the private keys of that address. So how can it be invalid? Also, could you specify which source(s) are saying that your address is invalid?

Im able to search for this address on blockchain (https://www.blockchain.com/explorer/addresses/btc/111113DUwES2ZNWSJztA3oBuhzfcdmiaG) and blockchair (https://blockchair.com/bitcoin/address/111113DUwES2ZNWSJztA3oBuhzfcdmiaG) explorers already. You have no balance with no transaction history, is that correct?

I suppose you are trying to import your keys in a different wallet but you could be using the wrong format hence the sources bring you invalid error?!

I used openAI, and she said this address is invalid, thanks for the reply.
I wanted to know if signing a message with invalid address was possible or not.

Not sure what is an OpenAI and what does she do :(
If it was possible, wouldn't everyone sign a message with any address they wish to? I guess this would break all the security rules of bitcoin, lol.
So the answer is no, impossible!

There's a reason why ChatGPT answers are banned in multiple platforms and forums, that's on example.
I've also seen users here who referenced ChatGPT answers and some are too generic, if not, incorrect.
Give it a few more years before taking its answers into account.

I think you misunderstood the question.

I wonder if the AI (or maybe AD, "artificial dumbass") actually decoded the base58 address and messed up on converting the ones to zeros and and reporting the final hash after removing the initial zeros for being zero ergo enduing up with a 16-byte hash instead of 20.
That's the only reason I can think of for a tool to reject a bitcoin address like 111113DUwES2ZNWSJztA3oBuhzfcdmiaG.

AI have their own disadvantages too, they can give wrong information, they are not 100% accurate. I wonder people are now using AI for checking if an address is correct or wrong, I will advice you to import the address on a wallet to know if it is valid or not or just use a blockchain explorer for it.

If you are able to sign a message with the address on Electrum, that means you generate or import the private key of the address on the same Electrum wallet that you used to sign the message. That alone shows that the address is valid.

Firstly, that address is perfectly valid.
Secondly, you sign a message using the private key associated with an address, not the address itself.

OpenAI doesn't run any kind of computation at all except for their neural network, when you interact with its bot(s).

There's no such thing as an "an invalid address that can't be used to sign a message". Messages are signed with private keys (as you know), and the address is actually irrelevant as it can be derived from the private key anyway.

This is my answer. Thank you all for replying.
