 [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) blockchain. bch-js contains a toolbox of handy tools, and an easy API for talking with [psf-bch-api REST API](https://github.com/Permissionless-Software-Foundation/psf-bch-api). [FullStack.cash](https://fullstack.cash) offers paid cloud access to psf-bch-api. You can run your own infrastructure by following documentation on [CashStack.info](https://cashstack.info).

-## 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.
-
-- Full SLP tokens support: bch-js has full support for all SLP token functionality, including send, mint, and genesis transactions. It also fully supports all aspects of [non-fugible tokans (NFTs)](https://www.youtube.com/watch?v=vvlpYUx6HRs).
-
-- [Semantic Release](https://github.com/semantic-release/semantic-release) for
-  continuous delivery using semantic versioning.
-
-- [IPFS](https://ipfs.io) and [Radicle](https://radicle.xyz) uploads of all files and dependencies, to backup
-  dependencies in case they are ever inaccessible from GitHub or npm.
