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

 ### Quick Notes

- Install library: `npm install @chris.troutner/bch-js`
+- Install library: `npm install @psf/bch-js`

 - Instantiate the library in your code:
+
 ```
-const BCHJS = require("@chris.troutner/bch-js")
-let bchjs = new BCHJS()
+const BCHJS = require("@psf/bch-js")
+let bchjs = new BCHJS() // Defaults to BCHN network.

 // testnet
-bchjs = new BCHJS({ restURL: 'https://tapi.fullstack.cash/v3/' })
+bchjs = new BCHJS({ restURL: 'https://testnet3.fullstack.cash/v3/' })
 ```

-This is a fork of the [BITBOX SDK](https://github.com/Bitcoin-com/bitbox-sdk) (which is maintained by Bitcoin.com). This library is intended to be paired with
-the [bch-api](https://github.com/christroutner/bch-api) REST API.
+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:

-If you need a backward-compatible instance of this library, you can use a
-'shim'. Do it like this:
-```
-const BCHJS = require("@chris.troutner/bch-js")
-const bitbox = BCHJS.BitboxShim({ restURL: 'https://api.fullstack.cash/v3/' })
-```
+- BCHN Mainnet REST API server: https://bchn.fullstack.cash/v3/
+- ABC Mainnet REST API server: https://abc.fullstack.cash/v3/
+- Testnet3 REST API server: https://testnet3.fullstack.cash/v3/
+- Check server status: https://metrics.fullstack.cash

 ### API Key
-The [bch-api](https://github.com/christroutner/bch-api) REST API hosted by [FullStack.cash](https://fullstack.cash) uses JWT tokens to pay for increased
-rate limits when interacting with the back end server. See [this article](https://troutsblog.com/research/bitcoin-cash/how-to-bch-full-stack-developer) if you want to understand the system-as-a-whole. The JWT token can be fed to bch-js *implicitly* or *explicitly*.

- Implicitly: bch-js will detect your JWT token by setting the `BCHJSTOKEN` environment variable.

+- Implicitly: bch-js will detect your JWT token if you set the `BCHJSTOKEN` environment variable.
 - Explicitly: You can directly feed in the JWT token with the `apiToken` property when instantiating the library. Here is an example:

+const BCHJS = require("@psf/bch-js")
 let bchjs = new BCHJS({
-  restURL: 'https://api.fullstack.cash/v3/',
+  restURL: 'https://bchn.fullstack.cash/v3/',
  apiToken: 'eyJhbGciO...' // Your JWT token here.
 })
 ```

 ### Gatsby
+
 bch-js is included in this [gatsby-ipfs-template](https://github.com/Permissionless-Software-Foundation/gatsby-ipfs-template) for building uncensorable web apps that can interact with the blockchain. When building a Gatsby (or other front-end app that uses Webpack), you'll need to add these lines to your `gatsby-node.js` file, as per [this issue](https://github.com/gatsbyjs/gatsby/issues/564):
+
 ```

  actions.setWebpackConfig({
@@ -75,60 +78,47 @@ exports.onCreateWebpackConfig = ({ actions }) => {

 This is because the new IPFS class in bch-js uses the fs library for uploading files, which is not supported by Gatsby.

+We also provide [minimal-slp-wallet-web](https://www.npmjs.com/package/minimal-slp-wallet-web) as a basic Bitcoin Cash wallet with SLP support, for front end projects. bch-js is encapsulated inside the instantiation of the library Class.

 ## Features
-This library sets itself apart from BITBOX with the following features:

 - [ECMAScript 2017 standard JavaScript](https://en.wikipedia.org/wiki/ECMAScript#8th_Edition_-_ECMAScript_2017) used instead of TypeScript. Works
-natively with node.js v10 or higher.
