Bech32 CashAddr

This project implements the base encoding used by CashAddr, the modified version of Bech32 described in the Bitcoin Cash specification. It focuses on the generic encoding layer: converting between the human-readable part, base32 payload, and checksum without any coin-specific version byte logic.

Specification: https://github.com/bitcoincashorg/bitcoincash.org/blob/master/spec/cashaddr.md

Install

npm i bech32cashaddr

Usage

import { cashaddr } from 'bech32cashaddr';

const prefix = 'bitcoincash';
const data = Uint8Array.of(
  0, 1, 2, 3, 4,
  5, 6, 7, 8, 9
);
const words = cashaddr.toWords(data);

const encoded = cashaddr.encode(prefix, words);
console.log(encoded); // bitcoincash:qqqsyqcyq5rqwzqf50xhu6j9

const decoded = cashaddr.decode(encoded);
console.log(decoded.prefix); // bitcoincash
console.log(cashaddr.fromWords(decoded.words)); // [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
