I have the following code in my frontend, how would I verify that the signature is correct in the backend?

import {
  signMessage,
  SignMessageOptions,
} from "sats-connect";

async signMessage(
  address: string,
  msg: string,
): Promise<string> {
  return new Promise(async (resolve, reject) => {
    const signMessageOptions: SignMessageOptions = {
      payload: {
        message: "foobar",
        address,
        network: {
          type: "Mainnet",
        },
      },
      onFinish: (response) => resolve(response),
      onCancel: () => reject(new Error()),
    };

    await signMessage(signMessageOptions);
  });
}

Hello I would like to inscribe with this library. Can you provide an example of a valid psbt?

Hey guys i have been trying to form OP_RETURN output using sats-connect

I have to send an EVM address (20bytes) in OP_RETURN data for my dApp

Please help me here:
I've reached this far in figuring this out

tx.addOutput({
      script: btc.Script.encode([
        'RETURN',
        new TextEncoder().encode('abc')
      ]),
      amount: 0n
    })

When I use the sats-connect-example app as it is without any changes, and generate a PSBT and sign it it fails to broadcast it onto the network. I did some digging by copying base64 of signed transaction, and it fails to broadcast it even on Sparrow wallet:

non-mandatory-script-verify-flag (Witness program was passed an empty witness)

I checked and there is no signature for the Ordinal lock script to unlock the funds. So it means the signTransaction fails to add the signature. It does add for Paying address but not for Ordinal address.

i am creating a psbt following the sats connect example. i am able to create it and also sign it. If i set broadcast: false i get back the signed psbt. if i set it to true, it shows it correctly in the wallet, but then when i click confirm it shows a 400 error

Hello, I managed to fix the issue with deployments in Vercel and deployed it here:

Please ping if it's still relevant and I can make a PR.
