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

Using LedgerJS for Sui

Here is a sample app for Node:

const Transport = require('@ledgerhq/hw-transport').default;
const Sui = require('@mysten/ledgerjs-hw-app-sui').default;

const getPublicKey = async () => {
	const sui = new Sui(await Transport.create());
	return await sui.getPublicKey("44'/784'/0'/0'/0'");
};

const signTransaction = async () => {
	const sui = new Sui(await Transport.create());
	return await sui.signTransaction("44'/784'/0'/0'/0'", '<transaction contents>');
};

const getVersion = async () => {
	const sui = new Sui(await Transport.create());
	return await sui.getVersion();
};

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

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