**The goal of the Offsetting Component module development** is to build a carbon footprint offsetting solution which immediately after completion can be integrated easily with a specific crypto exchange partner’s mobile apps. Following integration, the partner’s clients will be able to purchase carbon offsets on a voluntary basis. The integrated Offsetting
Component module will allow the customers of the partner exchange to purchase carbon offsets from ImpactScope without leaving the partner’s Android and iOS mobile apps.

The Offsetting Component module will use React.js and Webpack. Firebase will be used to collect anonymized user interaction statistics. The  Component module will integrate into anexisting Angular framework V10 via webview.

**Stack:**

● React.js
● Node.js
● Firebase
● Webpack
● NPM (for hosting package)
