Since sending the actual transaction would require me to sign the transaction anyway, what is the purpose of authenticating me? Wouldn't the transaction be enough to be certain that I'm the one sending it? | |
| Dec 27, 2021 at 11:19 | comment | added | Richard | Often signed messages are used as an authentication mechanism, so that the interface knows that you actually have access to the address that is provided. To provide more details you would have to share an example DEX where you see this behaviour. | |
