OST Server-Side JavaScript SDK

OST Platform SDK for JavaScript.

Introduction

OST is a complete technology solution enabling mainstream businesses to easily launch blockchain based economies without requiring blockchain development.

Brand Tokens (BTs) are white-label cryptocurrency tokens with utility representations running on highly-scalable Ethereum-based utility blockchains, backed by value token (such as OST, USDC) staked on Ethereum mainnet. Within a business`s token economy, BTs can only be transferred to whitelisted user addresses. This ensures that they stay within the token economy.

The OST technology stack is designed to give businesses everything they need to integrate, test, and deploy BTs. Within the OST suite of products, developers can use OST Platform to create, test, and launch Brand Tokens.

OST APIs and server-side SDKs make it simple and easy for developers to integrate blockchain tokens into their apps.

For documentation, visit https://dev.ost.com/

Getting Started

Setup Brand Token

Sign-up on OST Platform and setup your Brand Token.
Obtain your API Key and API Secret from developers page.

Installation

The preferred way to install the OST JavaScript SDK is to use the npm package manager for Node.js. Simply type the following into a terminal window:

 npm install @ostdotcom/ost-sdk-js

< AE20 div class="markdown-heading" dir="auto">

Usage

  2. Testnet: "https://api.ost.com/testnet/v2/"
*/
let apiEndpoint = 'https://api.ost.com/testnet/v2/';

// Optional API parameters

// This is the timeout in seconds for which the socket connection will remain open.
