When I sign the message with one of my BTC addresses on Electrum and then verify it on the same wallet it says "wrong signature". The same message signed with other BTC addresses is correct. How to resolve this issue?
The address is native segwit (starts with bc1).
It might be a copy-paste issue.If you have created the message by some text redactor like WORD and transfer in to Electrum via copy-paste then It might be messed with reserved character. Try to put you message into Electrum by using keyboard.
Thank you for your advice.
I tried to put the message by using keyboard, but it didn't help.
The message is still the same and incorrect.
There is still no common standard to sign from bc1 address... so might be some strange combination of characters that mislead Electrum's signer... could you sign if HEX string in your message would be removed?
