Plug & Play JavaScript library for all Bitcoin Cash address format translation needs. Easy-to-use, thoroughly tested, and feature complete.
Support for the new Bitcoin Cash address format which improves upon BIP 173, as well as the Bitpay and Legacy formats.
Test out a demo address translator powered by BchAddr.js here.
$ npm install bchaddrjs
$ yarn add bchaddrjs
You may also download the distribution file manually and place it within your third-party scripts directory: dist/bchaddrjs-0.5.2.min.js.
// Common-JS
var bchaddr = require("bchaddrjs");
// ES6 modules
import bchaddr from "bchaddrjs";You may include a script tag in your HTML and the bchaddr module will be defined globally on subsequent scripts.
