The following example uses Particle Connect instead of Particle Auth. It shows how to sign and send a Universal Account transaction using a connected wallet.
When using Particle Connect, you can access the connected wallet through the useWallets() hook. The primaryWallet object exposes a walletClient, which acts as the signer. This lets you sign the Universal Account transaction payload (rootHash) using any wallet connected via Particle Connect. The following code snippet shows how to use the Universal Accounts SDK to sign a transaction with Particle Connect: 
import { useWallets, useAccount } from "@particle-network/connectkit";
import { CHAIN_ID } from "@particle-network/universal-account-sdk";

// Get wallet from Particle Connect
const [primaryWallet] = useWallets();
const walletClient = primaryWallet?.getWalletClient();
const { address } = useAccount();

// Create a cross-chain transfer transaction via Universal Accounts
const transaction = await ua.createTransferTransaction({
  token: {
    chainId: CHAIN_ID.ARBITRUM_MAINNET_ONE,
    address: "0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9", // USDT on Arbitrum
  },
  amount: "0.1", // Amount to send (human-readable string)
  receiver: receiverAddress, // Target address
});

// Sign the transaction's root hash using connected wallet
const signature = await walletClient?.signMessage({
  account: address as `0x${string}`,
  message: { raw: transaction.rootHash },
});

// Send the signed transaction via Universal Account SDK
const sendResult = await universalAccount.sendTransaction(
  transaction,
  signature
);

// Log UniversalX explorer link
console.log(
  "Explorer URL:",
  `https://universalx.app/activity/details?id=${sendResult.transactionId}`
);
