Moralis General

Hi, I’m currently using react-moralis in my project, but I don’t know how to modify the authentication message in the metamask, can somebody help me with that? thanks!

Hey @tigerkev

In react Moralis you can just add into the code:

Moralis.getSigningData = () => "Custom message";
#3

Thanks for the help, I added the code like this, but it seems not working, did I mistake something?

import { useMoralis } from "react-moralis";
function App() {
  const { authenticate, isAuthenticated, logout, user, Moralis } = useMoralis();
  if (isAuthenticated) {
    return (
      <>
        <Button onClick={() => logout()}>Logout</Button>
        <p>User Name: {user.get("username")}</p>
        <p>User Address: {user.get("ethAddress")}</p>
        {Moralis.getSigningData = () => "Custom message"}
        {console.log(user)}
      </>
    );
  }

Hey @tigerkev

Input (Moralis.getSigningData = () => "Custom message")
on the top of the function:

import { useMoralis } from "react-moralis";
export default function App() {
  const { authenticate, isAuthenticated, logout, user, Moralis } = useMoralis();
  Moralis.getSigningData = () => "Custom message"
  
  return(
    <>
    </>
  )
}

Thanks, it works , thank you very much!

Hey Ivan, this function is not returning the response. Could you assist me with this?

did you use it with await Moralis.authenticate ?
