Nault is a free, open-source wallet for the Nano cryptocurrency, built for people who want to hold their own coins and keep control of their keys. It suits users who already use Nano and want a desktop application that can work alongside a Ledger hardware wallet.
The program is distributed as a ready-made build for Windows, macOS and Linux, and it is also available for Android, iOS, Docker and as a browser-based version. Because the code is public on GitHub, anyone can review how it works. The project's most recent code update is dated September 2026, so it appears to be actively maintained, but it is still worth checking the release notes before you rely on it for larger amounts.
What Is Nault and Who Is It For?
Nault is a non-custodial wallet, which means the software holds your keys locally instead of a company holding them for you. That is the core idea behind self-custody, and it is the main reason people choose wallets like this one.
The typical user is someone who already owns Nano and wants a dedicated desktop tool rather than a web service. It also fits people who plan to pair their coins with a Ledger device and want a clear, focused interface for sending and receiving payments.
How Nano Differs From Bitcoin in Wallet Design
Nano uses a block-lattice structure, where each account has its own chain of transactions instead of one shared ledger block. Transfers are typically fast and free, which changes what a wallet needs to show. Instead of focusing on mining or long confirmation times, a Nano wallet mainly handles account balances, receiving pending funds, and representative selection.
Understanding this difference helps explain why Nault is narrower in scope than a multi-coin wallet. It is built around one network, so its screens and workflows are tailored to that network's behavior.
Real-World Scenarios for a Nano Desktop Wallet
A desktop wallet like Nault is useful when you want to manage larger balances from a computer you control. For example, you might keep the bulk of your Nano in a Ledger device and use the desktop app to view balances and initiate transfers, confirming each one on the hardware screen.
Another scenario is a small business or freelancer who accepts Nano payments and needs a reliable way to track incoming funds. In both cases, the value comes from separating daily use from long-term storage and from keeping the private key off internet-connected devices.
Key Terms Every Nault User Should Know
A seed phrase is the list of words that can recreate your wallet. Anyone who has it can take control of your funds, so it should be written down offline and never typed into a website. A hardware wallet is a small device that stores your private keys and signs transactions internally.
A representative in Nano is the account that votes on network consensus on behalf of your balance. Choosing a reliable representative matters because your funds still belong to you, but your voting weight is delegated. Knowing these terms makes the rest of the wallet settings much easier to understand.

How to install Nault on Windows
- 1
Download the Installer
Open the official Nault GitHub Releases page and choose the latest release. Download the installer for Windows. Avoid third-party download sites, and download only from the official site or GitHub.
- 2
Verify the File Checksum
Open PowerShell in the folder where you saved the file and run Get-FileHash -Path '.\Nault-Setup-x.x.x-Windows.exe' -Algorithm SHA256, replacing the version number with the one you downloaded. Compare the output with the SHA-256 value published on the release page. If they do not match, delete the file and download it again.
- 3
Run the Installer
Double-click the setup file and follow the on-screen prompts. Windows may show a security prompt for an application from an unknown publisher; check that the file came from the official release before continuing.
-
Connect a Ledger Device (Optional)
If you plan to use a Ledger Nano, connect it to your computer, unlock it with your PIN, and open the Nano app on the device. Then select the hardware wallet option in Nault and follow the pairing steps shown on screen.
System requirements
- A Windows version that supports the current Electron-based desktop application
- Enough free disk space for the application and local wallet data
- An internet connection to sync with the Nano network
- A Ledger Nano hardware wallet, if you want to use hardware wallet support
How to use Nault
Setting up Nault takes a few minutes once the program is installed. The wallet creates or imports a Nano account and then lets you send and receive funds. Take your time with the first setup, especially the backup step.
- Launch Nault and choose whether to create a new wallet or import an existing one.
- Write down the seed phrase on paper and store it somewhere safe and offline.
- Confirm the seed phrase when prompted to prove you recorded it correctly.
- To use a Ledger device, select the hardware option, connect the device, and open the Nano app on it.
- Copy your Nano address to receive funds, and check that the address matches exactly before sending.
- To send Nano, enter the recipient address and amount, then review the transaction carefully.
- If you use a Ledger, confirm the transaction on the device screen before it is signed.
- Check your balance and pending transactions after each transfer to make sure everything arrived.
Pros & cons
- Free and open source, so the code can be reviewed publicly
- Supports the Ledger Nano hardware wallet
- Focused interface for the Nano network
- Available on several operating systems and platforms
- Designed for Nano only, so it is not a multi-coin wallet
- Setup and hardware pairing can be confusing for beginners
- Windows builds are less prominently documented than Linux or macOS, so check the release notes carefully
- Requires careful personal backup, since there is no account recovery service
Is Nault safe?
Nault is a self-custody wallet, so the security of your funds depends mostly on how you install and use it. Download the installer only from the official GitHub Releases page, and compare the SHA-256 checksum with the value published on that page before running the file. A matching checksum confirms that the file has not been altered during download.
Never type your seed phrase into a website, a chat, or an email, and never share it with anyone who asks for it, including people claiming to be support staff. Use a Ledger hardware wallet if you hold meaningful amounts, and keep your computer's operating system and security software up to date. Antivirus tools sometimes flag wallet software, so investigate any warning, but do not turn off your protection to get the program running.
- Official source only. Download from github.com/nault/nault. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Nault is narrower than most of the wallets in this catalog. Cake Wallet, Coinomi, Exodus and Atomic Wallet all support many cryptocurrencies in one application, which is convenient if you hold several assets. Nault instead concentrates on Nano, so its menus and transaction flow are simpler if Nano is all you use.
Electron Cash is another single-network option, but it is built around Bitcoin Cash. Stack Wallet is open source and multi-currency, which may suit users who want more coins in one place. Trust Wallet is primarily a mobile app with a browser extension on desktop. If you specifically want a Nano wallet with hardware support, Nault is a focused choice; if you want variety, a multi-coin option may serve you better.

Frequently asked questions
Yes, Nault is free and open source. You can download the program from its official GitHub Releases page without paying a fee. Using the wallet still involves normal Nano network transaction costs, which are usually very low, and you should not expect any profit guarantees from holding coins.
Yes. Both the desktop and web versions of Nault support the Ledger Nano hardware wallet. When you use a Ledger, your private keys stay on the device, and you approve each transaction on the hardware screen before it is signed.
It can be, if you download it only from the official GitHub Releases page and verify the SHA-256 checksum against the value published there. Avoid third-party download sites, and never enter your seed phrase on a website. Keeping the software updated and using a hardware wallet for larger balances further reduces risk.
No. Nault is built for the Nano network, and its documentation describes support for Nano only. If you want to hold Bitcoin, Ethereum or other coins, you will need a wallet designed for those networks, such as a multi-currency option from the catalog.
Your seed phrase is shown when you create a new wallet, and it is the only way to recover the wallet if your computer fails. Write it down on paper and store it somewhere secure. Nault cannot show it again in the same way, so keep the backup safe from the start.
You can reinstall Nault on a new device and restore your wallet using your seed phrase. Funds are not tied to the application or to a company account. If you use a Ledger, you will also need the device and its PIN, so keep both safe.
Yes. The wallet needs to connect to the Nano network to sync your balance, see incoming transactions and send payments. Without a connection, you can still view the software, but you will not see up-to-date account information.
Verdict
Nault is a focused, free and open-source wallet for people who use Nano and want to keep control of their keys. Its Ledger support makes it a sensible choice for anyone holding meaningful amounts who wants hardware security with a desktop interface. If you need to hold many different cryptocurrencies in one app, a multi-currency wallet from this catalog will suit you better. Before installing, check the latest release and verify the file's checksum.
