hw-app-hash

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

Using LedgerJS for Provenance

Here is a sample app for Node:

const Transport = require("@ledgerhq/hw-transport").default;
const Provenance = require("hw-app-hash_token").default;

const getPublicKey = async () => {
  const hash_token = new Provenance(await Transport.create());
  return await hash_token.getPublicKey("44'/505'/0'/0/0");
};

const signTransaction = async () => {
  const transport = await Transport.create();
  const hash_token = new Provenance(await Transport.create());
  return await hash_token.signTransaction(
    "44'/505'/0'/0/0",
    "<transaction contents>"
  );
};

const getVersion = async () => {
  const transport = await Transport.create();
  const hash_token = new Provenance(await Transport.create());
  return await hash_token.getVersion();
};

const doAll = async () => {
  console.log(await getPublicKey());
  console.log(await signTransaction());
  console.log(await getVersion());
};

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

Examples

import Provenance from "hw-app-hash_token";
const hash_token = new Provenance(transport);

getPublicKey

Get Provenance address for a given BIP-32 path.

Parameters

• path string a path in BIP-32 format

Examples

const publicKey = await hash_token.getPublicKey("44'/505'/0'/0/0");

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

signTransaction

Sign a transaction with a given BIP-32 path.

Parameters

• path string a path in BIP-32 format

Examples

const publicKey = await hash_token.signTransaction(
  "44'/505'/0'/0/0",
  "<transaction contents>"
  );

Returns Promise<object> an object with text field containing a signature.

getVersion

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

Examples

console.log(await hash_token.getVersion());

for version 0.1.0, it produces something like

{
  major: 0
  minor: 1
  patch: 0
}

Returns Promise<{object}> an object with major, minor, and patch of the version.
