A [BIP32](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki) compatible library written in TypeScript with transpiled JavaScript committed to git.


## Example

TypeScript

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

let node: BIP32Interface = bip32.fromBase58('xprv9s21ZrQH143K3QTDL4LXw2F7HEK3wJUD2nW2nRk4stbPy6cq3jPPqjiChkVvvNKmPGJxWUtg6LnF5kejMRNNU3TGtRBeJgk33yuGBxrMPHi');

let child: BIP32Interface = node.derivePath('m/0/0');
// ...
```

NodeJS

``` javascript
let BIP32Factory = require('bip32').default
// tiny-secp256k1 v2 is ES module and must be imported, not required
// (This requires v14 of node or greater)
// But as long as you implement the interface, any library is fine
import('tiny-secp256k1').then(ecc => BIP32Factory(ecc)).then(bip32 => {
  let node = bip32.fromBase58('xprv9s21ZrQH143K3QTDL4LXw2F7HEK3wJUD2nW2nRk4stbPy6cq3jPPqjiChkVvvNKmPGJxWUtg6LnF5kejMRNNU3TGtRBeJgk33yuGBxrMPHi')

  let child = node.derivePath('m/0/0')
  // ...
})
```
