Using Particle Connect with Universal Accounts

// 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({

  },
  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(

// Log UniversalX explorer link
console.log(
