Message signing.

[Uruguruu]

I don't know if I'm too dumb to sign a message with my cold wallet but is there a way, that in app signing of messages is possible?

I found this Reddit Forum, talking about the same thing, but the solutions don't seem to be working for me, and I'm not finding any other guides/solutions. Forum

Why signing a Message? Some Exchanges like Pocket and Relai in this case both Swiss require you to sign a message before purchasing or selling Bitcoin to verify the ownership of the Wallet.

I agree with this feature request. Many (smaller) exchanges require signing a message to verify ownership of a BTC address. Currently the easiest way for me to do this is to use another (connected) wallet which I do not feel safe doing. I’d rather sign from my AirGap Vault.
