@axia-systems/hd-wallet

Ledger Hardware Wallet JavaScript bindings for Axia, based on LedgerJS.

Using LedgerJS for Axia

Here is a sample app for Node:

const Transport = require("@ledgerhq/hw-transport-node-hid").default;
const Axia = require("@axia-systems/hd-wallet").default;

const getWalletId = async () => {
  const axia = new Axia(await Transport.create());
  return await axia.getWalletId();
};

const signHash = async () => {
  const transport = await Transport.create();
  const axia = new Axia(await Transport.create());
  return await axia.signHash(
    "44'/9000'/0'/0/0",
    "0000000000000000000000000000000000000000000000000000000000000000"
  );
};

const getVersion = async () => {
  const axia = new Axia(await Transport.create());
  return await axia.getAppConfiguration();
};

const getAddress = async () => {
  const axia = new Axia(await Transport.create());
  return await axia.getWalletPublicKey("44'/9000'/0'/1/0");
};

const doAll = async () => {
  console.log(await getWalletId());
  console.log(await getVersion());
  console.log(await getAddress());
  console.log(await signHash());
};

doAll().catch(err => console.log(err));

API

Axia

Axia

Axia API for Ledger

Parameters

transport Transport<any>
scrambleKey string (optional, default "Axia")

Examples

import Axia from "@zee-ava/hd-wallet-axia";
const axia = new Axia(transport);

getWalletPublicKey

Get Axia address for a given BIP-32 path.

Parameters

path string a path in BIP-32 format

Examples

const publicKey = await axia.getWalletPublicKey("44'/9000'/0'/0/0");

Returns Promise<string> an object with a public key.

signHash

Sign a 32-byte hash of transaction with a given BIP-32 path

Parameters

path string a path in BIP-32 format
hash string hash of a to sign

Examples

const signature = await axia.signHash("44'/9000'/0'/0/0", "0000000000000000000000000000000000000000000000000000000000000000");

Returns Promise<string> a signature as hex string.

getAppConfiguration

Get the version of the application installed on the hardware device.

Examples

console.log(await axia.getAppConfiguration());

produces something like

{
  "version": "1.0.3",
  "commit": "1234567",
  "name": "Axc"
}

Returns Promise<{version: string, commit: string, name: string}> an object with a version.

getWalletId

Get the wallet identifier for the Ledger wallet. This value distinguishes different Ledger hardware devices which have different seeds.

Examples

console.log(await axia.getWalletId());

produces something like

abcdefgh

Returns Promise<string> a byte string.
