Node.js & JavaScript SDK for Evedex REST APIs & WebSockets

[TOC]

This SDK enables programmatic access to Evedex exchange services, including market data streaming, account metrics, and order management.

• Integration sdk with Evedex REST APIs and WebSockets.

• TypeScript support (with type declarations for most API requests & responses).

• Auth with wallet private keys or with API keys

• Realtime balances, positions, orderbook, and order state updates with cache management.

• Methods for working with orders by wallet account: create replace cancel orders.

• Includes internally sign request payloads for orders, positions and withdraw methods

Installation

1. Init npm project

2. Install exchange-bot-sdk dependency

npm i @evedex/exchange-bot-sdk --save

Usage

Initialize container

You can use demo (for testing purposes) or production environments. For initializing container you need to pass websocket instance.

If you are using Node environment you need to install ws additionally:

npm i ws --save

And use it during initialize container method

import { WebSocket } from "ws";

DEMO TRADING ENVIRONMENT

const container = new evedexSdk.DemoContainer({
  centrifugeWebSocket: WebSocket,
  wallets: {
    baseAccount: {
      privateKey: "0x...",
    },
  },
  apiKeys: {},
});

PRODUCTION ENVIRONMENT

const container = new evedexSdk.ProdContainer({
  centrifugeWebSocket: WebSocket,
  wallets: {
    baseAccount: {
      privateKey: "0x...",
    },
  },
  apiKeys: {},
});

Initialize account

Api key account

ApiKeyAccount is designed to read user account state, including: balances, positions, orders.

You can create api key if you already logged in to evedex exchange.

Go to profile menu by clicking on avatar at the upper right corner => go to settings => API => create API key

Init example

import * as evedexSdk from "@evedex/exchange-bot-sdk";

const container = evedexSdk.initContainer(evedexSdk.Environment.DEMO, {
  centrifugeWebSocket: WebSocket,
  wallets: {},
  apiKeys: {
    mainApiKey: {
      apiKey: "cUxD***uOUQ=",
    },
  },
});

// or
const demoContainer = new evedexSdk.DemoContainer({
  centrifugeWebSocket: WebSocket,
  wallets: {},
  apiKeys: {
    mainApiKey: {
      apiKey: "cUxD***uOUQ=",
    },
  },
});

Wallet account

WalletAccout has all posibilities to read user account state and also includes:

• Methods to work with orders (create, replace, cancel, mass cancel) with signing them internally

• Methods to work with positions

• Methods to work with balances

Init example

import * as evedexSdk from "@evedex/exchange-bot-sdk";

const container = new evedexSdk.DemoContainer({
  centrifugeWebSocket: WebSocket,
  wallets: {
    baseAccount: {
      privateKey: "0x...",
    },
  },
});

Balance

Balance instance is designed for calculate available user balance and handle exchange events.

Methods with get prefix returns cached state, here is list of this methods:

• getFundingQuantity(currency) —

• getPositionList() —

• getPosition(instrument) —

• getOrderList() —

• getTpSlList() —

• getAvailableBalance() —

• getPower(instrument) —

Methods with fetch prefix are used for retrieving data from REST API:

• fetchTpSlList(query) — Fetches TP/SL list

• fetchMe() — Fetches user info

• fetchPositions() — Fetches positions

• fetchOrders(orderListQuery) — Fetches orders

• fetchAvailableBalance() — Fetches available balance

• fetchOpenOrders() — Fetches open orders

Balance listen method subscribes for exchange events: updates positions, orders, funding, tpsl.

Signals are disgned for handling events:

• onAccountUpdate

• onFundingUpdate

• onPositionUpdate

• onOrderUpdate

• onTpSlUpdate

Sample

import * as evedexSdk from "@evedex/exchange-bot-sdk";

const container = new evedexSdk.DemoContainer({
  centrifugeWebSocket: WebSocket,
  wallets: {
    baseAccount: {
      privateKey: "0x...",
    },
  },
});

const account = await container.account("baseAccount");

const balance = account.getBalance();

balance.listen();

console.log(balance.getPower("BTCUSDT:DEMO"));

console.log(await balance.fetchOrders({ instrument: "BTCUSDT:DEMO" }));

balance.onAccountUpdate((a) => console.info(a));

How to get test USDT in Development environment

For your convenience there's a test faucet that immediately deposits 1000 USDT to your smart-account in Development environment.

1. The first run happens automatically when you register on https://demo-exchange.evedex.com

2. After that you can once in a while request test funds using the button "Request Demo Funds" in the bottom-right of the Exchange screen.

WalletAccount (extends SessionAccount)

This class extends the SessionAccount class, which extends the ApiKeyAccount.

WalletAccount contains ApiKeyAccount methods and provides methods for executing various trading actions.

To initialize WalletAccount you need to pass your wallet private key to container config.

Class Methods

• createWithdraw(withdraw) — method used to create a signed withdrawal request and sends it to the exchange gateway.
