Usage

Getting started is a simple case of importing the Client and instantiating an instance.

import HundredXClient from '100x-client'

const MY_PRIVATE_KEY = '0x...'

const Client = new HundredXClient(MY_PRIVATE_KEY)

The client can also accept a configuration object as the second parameter.

Key	Type	Default	Description
debug	boolean	false	Used to enable debug mode when running the client for additional logging.
environment	'testnet' | 'mainnet'	'testnet'	Specify the environment you wish to trade in.
rpc	string	Blast RPC based on environment	Specify a custom RPC url to used.
subAccountId	number	1	Specify a sub-account ID to use. This can be from 1-255.

import HundredXClient from '100x-client'

const CONFIG = {
  debug: false,
  environment: 'testnet',
  rpc: 'https://sepolia.blast.io',
  subAccountId: 1,
}
const MY_PRIVATE_KEY = '0x...'

const Client = new HundredXClient(MY_PRIVATE_KEY)

Getting started

To get started, you will need to deposit funds and make a trade. Let's look at how we can do that now. If you're in need of testnet funds, please head over to the 100x Discord server where we will be happy to help.

import HundredXClient from '100x-client'
import { OrderType, TimeInForce } from '100x-client/enums'

const MY_PRIVATE_KEY = '0x...'

const Client = new HundredXClient(MY_PRIVATE_KEY)

// Let's deposit 1000 USDB to get started. By default deposits are in USDB.
const { error, success, transactionHash } = await Client.deposit(1000)

// Now we can make an order. Let's go long on some ETH!
if (success) {
  const { error, order } = await Client.placeOrder({
    isBuy: true,
    orderType: OrderType.LIMIT,
    price: 2990,
    productId: 1002,
    quantity: 1,
    timeInForce: TimeInForce.GTC,
  })

  // Finally let's log out our order to check the details.
  console.log(order)
}
