Boltcard Wallet is a free, open-source Bitcoin wallet built for people who want to link a Bolt Card to their Lightning balance. It suits users who already run, or are willing to run, their own supporting services and who want a familiar wallet interface on Windows.
The project is a fork of BlueWallet with added support for linking Bolt Cards. Its latest release is v0.3.3, and the last code update dates from August 2023. Because of that gap, check the project's GitHub page before you rely on it for anything important.
What Is Boltcard Wallet and Who Is It For?
Boltcard Wallet is a wallet application rather than a standalone service. It connects to a Bolt Card Hub, which handles the card side of the setup, and to a LNDhub-style backend that manages the Lightning balance.
The wallet suits technically inclined users, small merchants testing Lightning payments, and developers who want to experiment with Bolt Cards. It is less suitable for someone who wants a plug-and-play app with no supporting infrastructure.
How Bolt Cards Work With a Lightning Wallet
A Bolt Card is an NFC card that stores a reference to your Lightning account. When you tap it on a compatible reader, the reader requests a payment from the backend, and the wallet balance settles the invoice.
The card itself holds no bitcoin. The funds stay in the Lightning balance behind the scenes, which is why the surrounding services matter so much.
Practical Scenarios for Using a Bolt Card Wallet
A few realistic uses include paying at a café that accepts Lightning through a card reader, using a card for small everyday purchases, or setting up a card as a tap-to-pay method for a community event.
In each case, the value comes from quick tap payments rather than scanning QR codes. Before you choose this setup, confirm that the merchant or reader actually supports Bolt Cards.
Understanding Self-Hosted Wallet Infrastructure
Running your own service means you control the software that holds your Lightning balance. That brings more responsibility: you must keep the server updated, secure its access, and back up its data.
For beginners this can be a steep learning curve. If you are not comfortable managing a server, a fully hosted wallet may be easier, even if it gives you less control.

How to install Boltcard Wallet on Windows
- 1
Choose a trusted download source
Download the program only from the official website or the project's GitHub Releases page. Avoid mirror sites and file-sharing links, since they can distribute modified builds.
- 2
Verify the file
Compare the file's SHA-256 checksum with the value published on the release page, or check the release signature if one is provided. Do not run the installer if the values do not match.
- 3
Run the installer
Launch the installer and follow the on-screen prompts. Install to a location you control, and keep Windows and your antivirus software up to date.
-
Connect to your services
Before linking a card, set up the Bolt Card Hub and the LNDhub-based backend the wallet relies on. The wallet cannot link cards without these running.
System requirements
- Windows with an installer or build available for your version
- A running Bolt Card Hub service to connect to
- A running boltcard-lndhub backend, the project's forked LNDhub
How to use Boltcard Wallet
Using Boltcard Wallet well depends on having the supporting services ready first. Once they are running, the wallet itself is straightforward to work with.
- Install the wallet and open it for the first time.
- Connect the wallet to your Bolt Card Hub and backend services.
- Create or import your wallet and write down the recovery phrase on paper.
- Link a Bolt Card from the card-linking screen and follow the prompts.
- Fund the Lightning balance so there is something to spend.
- Test the card with a small amount at a compatible reader before relying on it.
- Keep the backend and wallet updated and check your backups regularly.
Pros & cons
- Free and open source under the MIT license
- Built on a familiar wallet codebase (BlueWallet)
- Adds Bolt Card linking that the base wallet lacks
- Source code is publicly available for review
- Requires separate hub and backend services to function
- Last code update was in August 2023
- Limited to Bitcoin on the Lightning Network
- Setup is technical and not beginner-friendly
Is Boltcard Wallet safe?
Boltcard Wallet handles keys and funds, so treat security as a priority. Download the program only from the official website or the project's GitHub Releases page, and check the SHA-256 checksum or signature before installing. Never enter your recovery phrase on a third-party website or in a message from someone claiming to offer support.
Because the last code update is from 2023, review the GitHub repository for recent activity before storing meaningful amounts. Keep only what you need in a hot wallet, and back up your recovery phrase offline. Check the latest version on the official site before you install.
- Official source only. Download from github.com/boltcard/boltcard-wallet. 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
Boltcard Wallet differs from most of the similar programs in this catalog because its focus is narrow. Coinomi, Atomic Wallet and Exodus are multi-coin wallets that cover many assets, while Boltcard Wallet centers on Bitcoin over Lightning and Bolt Card use.
Electron Cash is a lightweight Bitcoin Cash wallet, and Trust Wallet is mainly a mobile or browser-extension option. If you want a simple desktop wallet for several coins, the alternatives are a better fit. If your goal is tapping a card to pay over Lightning, Boltcard Wallet is the more specialized choice.

Frequently asked questions
Yes, Boltcard Wallet is free to download and use. It is released under the MIT license, so the source code is also openly available. You may still need to run supporting services, which can involve their own costs, depending on how you host them.
A Bolt Card is needed only if you want to pay by tapping. The wallet can still be used for Lightning payments without one. The card linking feature is the main reason people choose this particular fork.
It can be, if you download it from the official website or GitHub Releases and verify the checksum before installing. Keep your recovery phrase offline and never share it. Because the last code update was in 2023, review the project's activity before storing significant amounts.
No. The wallet connects to a Bolt Card Hub and a LNDhub-based backend. Without those services running, card linking and balance operations will not work.
No, the wallet is built for Bitcoin on the Lightning Network. If you need several cryptocurrencies, a multi-coin wallet such as Coinomi or Atomic Wallet is more suitable.
A seed phrase is a set of words that can restore your wallet and its funds on any compatible software. Anyone who has it can access your balance, so store it offline and never type it into a website you did not verify.
It is better suited to users who are comfortable with technical setup. The need for a hub and backend adds steps that a simpler hosted wallet would not require.
Verdict
Boltcard Wallet is a focused, free and open-source option for people who want to link a Bolt Card to a Lightning balance on Windows. It rewards technical users who are willing to run supporting services and keep their software updated. Beginners who want a simple app, or anyone who needs several cryptocurrencies, will probably be better served by one of the multi-coin alternatives in this catalog.
