  privateKey: /* secp256k1 sec1 compressed secret key */,
});

const tokenId = 0;
try {
    await c.deposit(tokenId, 10000000);
} catch (e) {
    console.log(`couldn't do deposit, reason: ${e}`)
}

try {
    await c.withdraw(tokenId, 100);
} catch (e) {
    console.log(`couldn't do withdraw, reason: ${e}`)
}

const marketId = 0;
const size = 1;
const price = 1;
const isReduceOnly = false;
let orderID: number = 0;
try {
    orderId = await c.placeOrder(
        marketId,
