bip32grs

A BIP32 compatible library written in TypeScript with transpiled JavaScript committed to git.

Example

TypeScript

import BIP32Factory from 'bip32grs';
import * as ecc from 'tiny-secp256k1';
import { BIP32Interface } from 'bip32grs';
// You must wrap a tiny-secp256k1 compatible implementation
const bip32 = BIP32Factory(ecc);

const node: BIP32Interface = bip32.fromBase58('xprv9s21ZrQH143K3QTDL4LXw2F7HEK3wJUD2nW2nRk4stbPy6cq3jPPqjiChkVvvNKmPGJxWUtg6LnF5kejMRNNU3TGtRBeJgk33yuGBsoWepH');

const child: BIP32Interface = node.derivePath('m/17/0');
// ...

NodeJS

const ecc = require('tiny-secp256k1')
const { BIP32Factory } = require('bip32grs')
// You must wrap a tiny-secp256k1 compatible implementation
const bip32 = BIP32Factory(ecc)

const node = bip32.fromBase58('xprv9s21ZrQH143K3QTDL4LXw2F7HEK3wJUD2nW2nRk4stbPy6cq3jPPqjiChkVvvNKmPGJxWUtg6LnF5kejMRNNU3TGtRBeJgk33yuGBsoWepH')

const child = node.derivePath('m/17/0')
