    setupMode: SetupMode.SingleUser,
    signingMode: SigningMode.SuriBased,
};

const ACCOUNT = "5DAgx...";
const TOKEN_ETHEREUM_ADDRESS = "0x7e5bb...";

async function main() {
    await avnSdk.init();
    const api = await avnSdk.apis();

    let token_balance = await api.query.getTokenBalance(ACCOUNT, TOKEN_ETHEREUM_ADDRESS);
    console.log(token_balance);
