# BIP86

Derives taproot addresses from seed, xprv/xpub and tprv/tpub in javascript

## Installing

Run - `npm install bip86 --save`

## Using

```javascript

const BIP86 = require('bip86')

var mnemonic = 'abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about'

var root = new BIP86.fromMnemonic(mnemonic)

var child0 = root.deriveAccount(0)

console.log('mnemonic:', mnemonic)

console.log('rootpriv:', root.getRootPrivateKey())

console.log('rootpub:', root.getRootPublicKey())

console.log('\n');

var account0 = new BIP86.fromXPrv(child0)

console.log("Account 0, root = m/86'/0'/0'");

console.log('Account 0 xprv:', account0.getAccountPrivateKey())

console.log('Account 0 xpub:', account0.getAccountPublicKey())

console.log('\n');

console.log("Account 0, first receiving address = m/86'/0'/0'/0/0");

console.log('Prvkey:', account0.getPrivateKey(0))

console.log('Pubkey:', account0.getPublicKey(0))

console.log('Address:', account0.getAddress(0))

console.log('\n');

console.log("Account 0, second receiving address = m/86'/0'/0'/0/1");

console.log('Prvkey:', account0.getPrivateKey(1))

console.log('Pubkey:', account0.getPublicKey(1))

console.log('Address:', account0.getAddress(1))

console.log('\n');

console.log("Account 0, first change address = m/86'/0'/0'/1/0");

console.log('Prvkey:', account0.getPrivateKey(0, true))

console.log('Pubkey:', account0.getPublicKey(0, true))

console.log('Address:', account0.getAddress(0, true))

console.log('\n');

var account1 = new BIP86.fromXPub(xpub)

console.log("Account 1, root = m/86'/1'/0'");

console.log('Account 1 xpub:', account1.getAccountPublicKey());

console.log('\n');

console.log("Account 1, first receiving address = m/86'/1'/0'/0/0");

console.log('Pubkey:', account1.getPublicKey(0))

console.log('Address:', account1.getAddress(0))

console.log('\n');

console.log("Account 1, second receiving address = m/86'/1'/0'/0/1");

console.log('Pubkey:', account1.getPublicKey(1))

console.log("Account 1, first change address = m/86'/1'/0'/1/0");

console.log('Pubkey:', account1.getPublicKey(0, true))

console.log('Address:', account1.getAddress(0, true))

console.log('\n');

console.log("Account 1, second change address = m/86'/1'/0'/1/1");

console.log('Pubkey:', account1.getPublicKey(1, true))

console.log('Address:', account1.getAddress(1, true))

console.log('\n');
