    JavaScript SDK for StarkEx

    starkex-clientlib-js is a JavaScript wrapper around the StarkEx API that can be used in both NodeJS and Browser environments.

    starkex-clientlib-js is written in ECMAScript6 and strongly typed and transpiled to ECMAScript5 using TypeScript.


    This package is Typescript ready

    // using npm
    npm i starkex-clientlib-js
    // using yarn
    yarn add starkex-clientlib-js

    How to use it

    The library is a default export.


    To use it browser, you need to use the code from browser.js file.]()

    <script src="path-to-local-library/browser.js"></script>

    or via CDN

    <script src="https://path-to-cdn-library/browser.js"></script>

    In this scenario, the library will be bound to the global window object with the property StarkExAPI.

    window.StarkExAPI or simple StarkExAPI can be used to access the library.

    If you have a toolchain available you can use an import statement.

    import StarkExAPI from 'starkex-clientlib-js/browser';
    const StarkExAPI = require('starkex-clientlib-js/browser');

    Because is a default export, here you can import it with what name you want


    For NodeJS environment, just replace browser with node

    import StarkExAPI from 'starkex-clientlib-js/node';
    const StarkExAPI = require('starkex-clientlib-js/node');


    The object imported is a class that first needs to be instantiated:

    new StarkExAPI(config: StarkExClientConfig): StarkExClient;

    Where config is a configuration object of form:

    interface StarkExClientConfig {
      endpoint: string;
      // optional - relevant only for node environment
      certs?: {
        cert: string;
        key: string;
        ca?: string;


    const starkExAPI = new StarkExAPI({
      endpoint: ''

    Example with certs (NodeJS environment)

    const starkExAPI = new StarkExAPI({
      endpoint: '',
      certs: {
        cert: 'USER_CERT',
        key: 'USER_KEY'

    The StarkExClient object returned from the constructor exposing the different gateways existing on this API:

    public gateway: Gateway

    This is the StarkEx Services HTTP gateway version2 for all external trading interactions.

    Example for is_alive

    const isAlive = await starkExAPI.gateway.isAlive();
    console.log(isAlive); // gateway is alive!

    Example for get_first_unused_tx_id

    const txId = await starkExAPI.gateway.getFirstUnusedTxId();
    console.log(txId); // 69

    Example for a DepositRequest

    const request = {
      amount: 4029557120079369747,
      starkKey: "0x7c65c1e82e2e662f728b4fa42485e3a0a5d2f346baa9455e3e70682c2094cac",
      tokenId: "0x2dd48fd7a024204f7c1bd874da5e709d4713d60c8a70639eb1167b367a9c378",
      vaultId: 1654615998
    const response = await starkExAPI.gateway.deposit(request);
    console.log(response); // {"code": "TRANSACTION_PENDING"}

    Full API docs for gateway can be found here.

    public feederGateway: FeederGateway

    This is the StarkEx Services HTTP gateway for feeder interactions. The Feeder is a gateway to the StarkEx system for retrieving transaction batch information by external parties

    Example for get_batch_ids

    const batchIds = await starkExAPI.feederGateway.getBatchIds();
    console.log(batchIds); // [10000, 12345]

    Full API docs for feederGateway can be found here.

    public availabilityGateway: AvailabilityGateway

    This is the StarkEx Services HTTP gateway for committee interactions.

    Example for get_batch_data

    const batchId = 5678;
    const batchData = await starkExAPI.availabilityGateway.getBatchData(batchId);
    console.log(batchData); // {...}

    Full API docs for availabilityGateway can be found here.

    Note: All results will be exactly the raw response from the API.
