Sign a message

import {useSignMessage, useWallets} from '@privy-io/react-auth';

const {signMessage} = useSignMessage();
const {wallets} = useWallets();

const uiOptions = {
  title: 'You are voting for foobar project'
};

const {signature} = await signMessage(
  {message: 'I hereby vote for foobar'},
  {
    uiOptions,
    address: wallets[0].address // Optional: Specify the wallet to use for signing. If not provided, the first wallet will be used.
  }
);

import {useSignMessage} from '@privy-io/react-auth';

const {signMessage} = useSignMessage({
  onSuccess: ({signature}) => {
    console.log(signature);
    // Any logic you'd like to execute after a user successfully signs a message
  },
  onError: (error) => {
    console.log(error);
    // Any logic you'd like to execute after a user exits the message signing flow or there is an error
  }
});

// Then call `signMessage` in your code, which will invoke these callbacks on completion
