Introduction
@polymathnetwork/sdk - v2.0.1-beta.126
Getting Started
Purpose
The Polymath SDK's main goal is to provide external developers with a set of tools that will allow them to build powerful applications that interact with the Polymath protocol. It focuses on abstracting away all the complexities of the smart contracts (and the blockchain itself) and expose a simple but complete interface. The result is a feature-rich, user-friendly node.js library.
Before moving on
This document assumes you are already familiar with Security Tokens in general and Polymath in particular.
Technical Pre-requisites
In order to use the Polymath SDK, you must install node (version 10) and npm. The library is written in typescript, but can also be used in plain javascript. This document will assume you are using typescript, but the translation to javascript is very simple.
How to use
Installation
npm i @polymathnetwork/sdk --save
Or, if you're using yarn
yarn add @polymathnetwork/sdk
Initializing the client
Before you can start creating Security Tokens and launching STOs, you have to connect the Polymath SDK client to an Ethereum node. This is a pretty straightforward process:
Here is an overview of the parameters passed to the connect
function:
providerUrl
is a URL that points to a running Ethereum nodeprivateKey
is the private key of the wallet that will be performing transactions
NOTE: if using the SDK on a browser environment (i.e. with MetaMask), there is no need to supply the node URL nor the private key.
