What is @ethersproject/hdnode?

@ethersproject/hdnode is a package from the ethers.js library that provides functionality for working with Hierarchical Deterministic (HD) wallets. It allows developers to generate and manage HD nodes, derive child keys, and perform various cryptographic operations related to HD wallets.

What are @ethersproject/hdnode's main functionalities?

Generate HD Node from Mnemonic

This feature allows you to generate an HD node from a mnemonic phrase. The code sample demonstrates how to create an HD node using a mnemonic and print its extended key.

const { HDNode } = require('@ethersproject/hdnode');
const mnemonic = 'test test test test test test test test test test test junk';
const hdNode = HDNode.fromMnemonic(mnemonic);
console.log(hdNode.extendedKey);

Derive Child Node

This feature allows you to derive a child node from a parent HD node using a specific derivation path. The code sample demonstrates how to derive a child node and print its address.

const { HDNode } = require('@ethersproject/hdnode');
const mnemonic = 'test test test test test test test test test test test junk';
const hdNode = HDNode.fromMnemonic(mnemonic);
const childNode = hdNode.derivePath("m/44'/60'/0'/0/0");
console.log(childNode.address);

Sign a Message

This feature allows you to sign a message using the private key of an HD node. The code sample demonstrates how to sign a message and print the signature.

const { HDNode } = require('@ethersproject/hdnode');
const mnemonic = 'test test test test test test test test test test test junk';
const hdNode = HDNode.fromMnemonic(mnemonic);
const message = 'Hello, world!';
const signature = hdNode.signMessage(message);
console.log(signature);
