The Universal Accounts SDK lets you send tokens to any address across supported chains using the createTransferTransaction() method. Like other transactions, transfers don’t require the user to hold assets or gas tokens on the destination chain—liquidity and gas are abstracted behind the scenes. Once you construct the transfer, the SDK returns a rootHash to sign. You sign it with the connected EOA (e.g., from Particle Auth), then call sendTransaction() to broadcast: 
import { CHAIN_ID, UniversalAccount } from "@particle-network/universal-account-sdk";
import { useEthereum } from "@particle-network/authkit";

const { provider } = useEthereum();

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
});

const signature = await provider.signMessage(transaction.rootHash);
const result = await ua.sendTransaction(transaction, signature);

console.log("Explorer URL:", `https://universalx.app/activity/details?id=${result.transactionId}`);
For native assets like ETH, the token address will be 0x0000000000000000000000000000000000000000.
The returned TransactionResult will include the transaction ID, as well as metadata like token movements and fee breakdowns. You can find more details about this in the sendTransaction() Response Structure page.
