Can I get callers address from destination chain? #47

If I send a message over axelar to a contract on destination chain B, is there any way for that contract to verify the message came from me and not someone else?

Yes, you can verify the origin of a message sent to a contract on a destination chain. The Axelar network decentrally verifies and signs the truth of the source transaction, chain, and address. Then, this is available to you for authorization as part of your _execute method. We handle authentication; you handle authorization.

We made a video on this; take a look at it here.
