Helio SDK

Introduction

The Helio SDK is a packaged module to make integrating Helio and our components as easy and as quickly as possible into your front end web site or store so you can start accepting Helio web3 payments.

It wraps and enhances the Helio API away into one NPM package which is easy to install and upgrade.

The Helio SDK is is written in Typescript.

Please use the latest production version. Only used ALPHA versions if advised to do so.

Solana is currently supported with Polygon and ETH following soon.

Installation

yarn add @heliofi/sdk

After installing the SDK please import this into your project:

import { Helio } from "@heliofi/sdk";
