```js
import { Bip32PrivateKey } from "@stricahq/bip32ed25519";

... // Bip39 entropy from mnemonics
const rootKey = await Bip32PrivateKey.fromEntropy(entropy);
...

// hardened derivation
const accountKey = rootKey
      .derive(2147483648 + 1852) // purpose
      .derive(2147483648 + 1815) // coin type
      .derive(2147483648 + 0); // account index

const spendingKey = accountKey
      .derive(0) // chain
      .derive(0) // payment key index
      .toPrivateKey();

# @stricahq/ouroboros-network-js
Ouroboros network library written in typescript with nodejs streaming module. This library has been developed with extensive testing and research done by communicating with Haskell Cardano Node with edge cases and scenarios. Supports multiplexing and streaming for seamless communication between clients. Simple yet sophisticated project structure and modular design of multiplexer and de-multiplexer to support all ouroboros mini protocols without hassle.

✅ Supports communication over unix socket and TCP
✅ Built using nodejs Stream for efficient communication
✅ Stable multiplexer and de-multiplexer
✅ Modular and scalable design

## Supported Protocol ID
32784

## Currently Implemented Mini Protocols
- Local Chain Sync
- Local Transaction Submission
- Local Tx Monitor

Please note that this is only a networking library and is polymorphic in nature. Use [cbors](https://github.com/StricaHQ/cbors) and [Cardano Codec](https://github.com/StricaHQ/cardano-codec) for decoding and parsing the Cardano data objects returned by the mini protocols.

Please create an issue if you want to add support for another mini protocol
