GcoinJS (gcoinjs-lib)

The pure JavaScript Gcoin library for node.js and browsers. Forked from BitcoinJS.

Installation

npm install gcoinjs-lib

Setup

Node.js

var gcoin = require('gcoinjs-lib')

Examples

For most part of the library, it is the same as bitcoinjs-lib. The main different part from Gcoin to Bitcoin is that Gcoin support multi-color native currency. As a result, when creating new transaction, the addOutput([:address], [:amount], [:color]) method of the TransactionBuilder is different. The color should be added into the last parameter.
