 [bch-js](https://www.npmjs.com/package/@psf/bch-js) is a JavaScript npm library for creating web and mobile apps that can interact with the Bitcoin Cash (BCH) blockchains. It can be used for free, but requires an account on [FullStack.cash](https://fullstack.cash) for increased rate limits. Learn more from [this article](https://troutsblog.com/research/bitcoin-cash/how-to-bch-full-stack-developer) about Full Stack Bitcoin Cash development.

 This library is intended to be paired with
 the [bch-api](https://github.com/Permissionless-Software-Foundation/bch-api) REST API, and the infrastructure provided by [FullStack.cash](https://fullstack.cash). The `restURL` property can be changed to work with different Bitcoin Cash networks:

- BCHN Mainnet REST API server: https://bchn.fullstack.cash/v3/
- ABC Mainnet REST API server: https://abc.fullstack.cash/v3/
