You can convert Primary Assets with the createConvertTransaction method. The example below demonstrates how to convert any primary asset into another—USDC on Arbitrum, in this case: 
import { CHAIN_ID, SUPPORTED_TOKEN_TYPE, UniversalAccount } from "@particle-network/universal-account-sdk";
import { useEthereum } from "@particle-network/authkit";

// extract the provider from Particle Auth
const { provider } = useEthereum();

// In your app
const transaction = await ua.createConvertTransaction({
    expectToken: { type: SUPPORTED_TOKEN_TYPE.USDC, amount: '1' },
    chainId: CHAIN_ID.ARBITRUM_MAINNET_ONE,
});

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}`);
This method is useful to convert assets directly to your target chain (for example, upon deposit).
