btc-tools

Collection of utilities for bitcoin and litecoin (both mainnet and testnet for all coins).

Each util can be used:

on command line as standalone script
as a module

Command line utils will be symlinked by npm into prefix/bin (e.g. /usr/local/bin on Ubuntu) for global installs:

npm i -g btc-tools

or ./node_modules/.bin/ for local installs:

npm i btc-tools

The command line utils are prefixed with btc-tools- and they are:

btc-tools-derive
btc-tools-convert
btc-tools-generate
btc-tools-multisig

All print their output on stdout and you can choose between table and json format.

'derive'

Derives addresses and other related information given:

ext key (pub or prv)
network
path (optional)

All following examples evaluate root + 2 derived addresses for several paths.

Usage on cli

btc-tools-derive -h

'convert'

Utility that does conversions:

It can convert from one type of extended key to another. Despite the name it applies to extended private and as well as extended public keys.
privKey to WIF
WIF to privkey

Meaningful conversions between any two of same group:

mainnet xprv: ['xprv', 'yprv', 'Yprv', 'zprv', 'Zprv']
mainnet xpub: ['xpub', 'ypub', 'Ypub', 'zpub', 'Zpub']
testnet xprv: ['tprv', 'uprv', 'Uprv', 'vprv', 'Vprv']
testnet xpub: ['tpub', 'upub', 'Upub', 'vpub', 'Vpub']

'multisig'

Generates multisig addresses. Can be used in two ways.

Case 1: given list of N public keys and a threshold M, it returns a single M-of-N multisig address.
Case 2: Given N extended pub keys (mainnet: 'xpub', 'ypub', 'Ypub', 'zpub', 'Zpub' or testnet: 'tpub', 'upub', 'Upub', 'vpub', 'Vpub'), a threshold M and a derivation path, it returns a list of M-of-N multisig addresses.

NOTE: In either case the order of the supplied keys is important.

Supported multisig formats (--multisig-type, -T parameter):

p2sh (classical)
p2shp2wsh (wrapped segwit)
p2wsh (native segwit)
