@SanghamitraBhowmick1993 I have added the support for sign message operation, I think you will need to ask Hairy where you can test this feature but I have tested It here.

How exactly should I test this within AXS? Do I need to perform any specific transactions in the dApp, or should I test this with a particular feature in AXS? Could you please provide more details?

@SanghamitraBhowmick1993 I don't where in the dapp It's used, Hairy should address this, But for testing I have provided a link for you, You will need to go there and perform a sign message action within AXS in Webview, Once done successfully you will get a signature.

@SanghamitraBhowmick1993 I have just pushed a fix for signature problem.
We can test It once we have the sign message in dapp.
