Message Signing
Sign Message
Learn how to sign a message using the Okto SDK.
The signMessage() method creates a signature for any message following the EIP191 standard. This function initiates the signing process, which can be executed using the OktoClient instance.
Example
import { useOkto } from '@okto_web3/react-native-sdk';
import { TouchableOpacity, Text, View } from 'react-native';
function SignMessage() {
const oktoClient = useOkto();
const message = "Hello Okto!";
async function handleSignMessage() {
try {
const signature = await oktoClient.signMessage(message);
console.log("Signed Message: ", signature);
} catch (error) {
console.error("Error in Signing Message: ", error);
}
}
return (
<TouchableOpacity onPress={handleSignMessage}>
<Text>Sign Message</Text>
</TouchableOpacity>
);
}Note
