# Signing a Message

Once a web application has connected to the ME Solana wallet, it can prompt users to sign a message, send transactions, and more. Signing is commonplace amongst many dApps, as it gives application owners the ability to verify ownership of the wallet. Signing a message does not require any transaction fees.

To invoke, you can call the `signMessage` method on the provider directly.

```javascript
import { MagicEdenProvider } from "../types/types";

/**
 * Prompts the user to sign a message using the MagicEden Provider object
 * @param {MagicEdenProvider} provider The MagicEdenProvider object
 * @param {string} message The message to sign
 * @returns {Promise<string>} A promise that resolves to the signed message
 * @throws {Error} If an unexpected error occurs while signing the message
 */
export const signMessage = async (
  provider: MagicEdenProvider,
  message: string
): Promise<string> => {
  try {
    const encodedText = new TextEncoder().encode(message);
    const signedMessage = await provider.signMessage(encodedText);
    return signedMessage;
  } catch (error) {
    console.warn(error);
    throw new Error("An unexpected error occured while signing the message.");
  }
};
```

Signing a message is relatively simple and doesn't require any real interaction with web3 libraries. Check out the [signMessage](https://github.com/Tcadle434/me-wallet-solana-react/blob/main/src/utils/signMessage.ts) functionality in the demo app for a more well rounded implementation.
