Interact with the Citrex Perpetual Exchange and trade BTC, ETH, SEI and other cryptocurrency perp futures with leverage. Live on Sei.

``bash
npm install citrex-sdk


or

yarn add citrex-sdk

or

pnpm add citrex-sdk

or

bun install citrex-sdk
`

Usage

Getting started is a simple case of creating a .env file, importing the Client and instantiating an instance.

The .env file should contain the necessary contract addresses to interact with the DEX. An up-to-date copy of the relevant contract addresses can be found in the Citrex API docs.

`sh
CIAO_MAINNET_ADDRESS=<0x7461cFe1A4766146cAFce60F6907Ea657550670d>
ORDER_DISPATCH_MAINNET_ADDRESS=<0x993543DC8BdFCba9fc7355d822108eF49dB6b9F9>

CIAO_TESTNET_ADDRESS=<...>
ORDER_DISPATCH_TESTNET_ADDRESS=<...>
`

`ts
import CitrexSDK from 'citrex-sdk'

const MY_PRIVATE_KEY = '0x...'

const Client = new CitrexSDK(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 | Sei 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. |

`ts
import CitrexSDK from 'citrex-sdk'

const CONFIG = {
debug: false,
environment: 'mainnet',
rpc: 'https://evm-rpc.sei-apis.com',
subAccountId: 1,
}
const MY_PRIVATE_KEY = '0x...'

const Client = new CitrexSDK(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.

`ts
import CitrexSDK from 'citrex-sdk'
import { OrderType, TimeInForce } from 'citrex-sdk/enums'

const MY_PRIVATE_KEY = '0x...'

const Client = new CitrexSDK(MY_PRIVATE_KEY)

// Let's deposit 1000 USDC to get started. By default deposits are in USDC.
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: 3150,
productId: 1002,
quantity: 0.1,
timeInForce: TimeInForce.GTC,
})

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

A series of useful enums can be imported from citrex-sdk/enums and used to help match against responses or compose payloads.

| Name | Values | Description |
|--------------|------------------------------------------------------------------------------------------|------------------------------------------------------|
| Environment | MAINNET \| TESTNET | The environment to use when initialising the client. |
| Interval | '1M' \| '5M' \| '15M' \| '30M' \| '1H' \| '2H' \| '4H' \| '8H' \| '1D' \| '3D' \| '1W' | The interval to use when fetching K-line data. |
| MarginAssets | USDC | Symbol values of supported margin assets. |
| OrderStatus | CANCELLED \| EXPIRED \| FILLED \| OPEN \| PENDING \| REJECTED | Defines the possible states an order can be in. |
| OrderType | LIMIT \| LIMIT_MAKER \| LIMIT_REDUCE_ONLY \| MARKET | Order types for building order payloads. |
| TimeInForce | GTC \| FOK \| IOC | Time in force values for building order payloads. |
