Pandacash CLI

When developing applications for Bitcoin Cash, it is important that its functionality is well-tested, as the app can potentially be dealing with large amounts of money. For testing purposes, there is a public Bitcoin Cash testnet, but this testnet can not be used without an internet connection, and obtaining larger amounts of BCH can be cumbersome. Finally, in earlier stages of development, many developers would rather not be using a public network already, and would rather develop locally until development has furthered.

This is where pandacash-cli comes in. pandacash-cli is a one-click Bitcoin Cash blockchain with pre-funded BCH addresses, enabling developers to quickly start working with BCH without any hassle. pandacash-cli is similar to ganache-cli, but for Bitcoin Cash. pandacash-cli is a wrapper around pandacash-core.

Prerequisites

To run pandacash-cli, make sure that Node.js is installed. On macOS these tools can be installed through Homebrew.

brew install node

Installation

npm install --global pandacash-cli

Usage

After installing pandacash-cli, it can be used as a command-line tool to quickly spin up a local development BCH blockchain with a single command. The local blockchain comes with ten pre-funded BCH addresses, which can be used in the local development process.

Command Line

$ pandacash-cli <options>

Options:

• -a or --accounts: Specify the number of accounts to generate at startup.
• -m or --mnemonic: bip39 mnemonic phrase for generating a PRNG seed, which is in turn used for hierarchical deterministic (HD) account generation.
• --debug: Show debug output from the bitcoin node.

Under the hood

PandaCash consists of the following components:

• bcash implementation of bitcoin cash node in regtest mode
  • Doesn't sync with other Bitcoin nodes, and immediately creates new blocks on every transaction.
• Prefunded addresses
  • 10 addresses with spendable BCH each, generated from a random mnemonic.
