# Signing a Message

When a web application has established a connection to the ME wallet, it can prompt users to sign a message. This 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.

[Sats Connect](https://docs.xverse.app/sats-connect-v1/methods/signmessage) provides an easy way to request message signing. Let's take a look at the code below.

```javascript
import { BitcoinNetworkType, signMessage } from 'sats-connect';

// in a real app, you'll use the ME 'payment' address returned after a connection
const nativeSegwitAddress = 'bc1qcdmvsc8qqk8sr2st3mttu6fsmfrjzh5xrf4dch'

async function signWalletMessage() {
  try {
    await signMessage({
      payload: {
        network: {
          type: BitcoinNetworkType.Mainnet,
        },
        address: nativeSegwitAddress,
        message: 'Hello World. Welcome to the Magic Eden wallet!',
      },
      onFinish: (response) => {
        alert(`Successfully signed message: ${response}`);
      },
      onCancel: () => {
        alert('Request canceled');
      },
    });
  } catch (err) {
    console.error(err);
  }
}
```

A successful prompt to sign a message will look something like this:

**Message Format**

The ME wallet currently follows the spec design in [BIP 322](https://bips.xyz/322) for message signature types for all addresses. We are looking into adding more explicit support for legacy/ECDSA signing, as we are aware this may be needed for certain circumstances.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs-wallet.magiceden.io/bitcoin/signing-a-message.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
