Grin Wallet is the reference wallet for Grin, a privacy-focused cryptocurrency, and it is aimed at people who want to send, receive and hold Grin from their own Windows computer. It is free and open source, and it is written in Rust. Because it runs as a command-line program, it suits users who are comfortable typing commands or who want a lean tool without extra layers.
The wallet comes from the Grin project itself, so it is the most direct way to work with the network's official software. The current release is v5.5.1, and the source code is published on GitHub, where you can read it and follow its development. Before you install anything, remember that this is a terminal tool rather than a graphical app, and that it handles your funds directly. The setup and safety steps below are worth reading in full.
What Is Grin Wallet and Who Is It For?
Grin Wallet is a tool for one specific cryptocurrency. Its main job is to let you hold Grin, create transactions, and keep track of the funds that belong to you. It is not a general portfolio app, and it does not try to be one.
The most natural users are people who already know they want Grin and want to manage it with the project's own software. That includes privacy-minded holders who prefer to keep their setup focused, and technically curious users who like to understand every layer of their tools. Developers who want to test Grin transactions or read the wallet code also fall into this group.
If you are new to cryptocurrency in general, this wallet asks more of you than a mobile app would. You will need to back up your seed phrase carefully, work in a terminal, and take time to learn how transactions move between you and the other party. Treat that learning curve as part of the cost of using software that is close to the source.
How MimbleWimble Shapes the Way Grin Wallet Works
Grin is built on MimbleWimble, a transaction design that aims to keep transaction data compact and to reveal less on the public ledger than many older designs. You do not need to understand the mathematics to use the wallet, but knowing the general idea explains some of its behavior.
In practice, the wallet is where this design meets you. It builds transactions, tracks which outputs belong to your wallet, and coordinates with the other party when a payment requires more than one step. This is why sending Grin is usually a multi-step process rather than a single click.
Because the process involves exchanging information with the other party, both sides need to be patient and careful. Double-check amounts and recipient details before you confirm, and expect that a transfer may take more than one exchange to complete. Understanding this flow helps you avoid mistakes that would otherwise look like software errors.
Key Terms and Everyday Use Cases
Several terms come up repeatedly when you work with a command-line wallet. A seed phrase is the list of words that can restore your wallet, and anyone who has it can access the funds. A balance shows the Grin your wallet controls, which may differ from what you expect while a transfer is still in progress.
A common scenario is a user who keeps a small Grin holding on a personal Windows PC and checks it occasionally from a terminal. Another is a developer who wants to test how Grin transactions behave before building something on top of the network. A third is someone who prefers a tool with no browser extension and no always-on background service.
In each case, the same habits apply. Keep your seed phrase offline, use a small amount when you are learning, and record every transfer you make so you can reconcile your balance later.

Supported coins
Grin Wallet works with Grin, the cryptocurrency it was built for. It is a single-network wallet, so it does not manage other coins. If you hold several assets, you will need a separate program for each network you use.
How to install Grin Wallet on Windows
- 1
Find the Official Release
Open the Releases page of the official Grin Wallet repository on GitHub at github.com/mimblewimble/grin-wallet. Choose the latest release, currently v5.5.1, and pick the Windows build or installer. The project also publishes builds for macOS and Linux, which you can skip on a Windows PC.
- 2
Verify the Download
Download only from the official website or the GitHub Releases page listed above. Compare the SHA-256 checksum of the file with the value published alongside the release, or check the signature if one is provided. If the values do not match, delete the file and do not run it.
- 3
Install or Extract the Wallet
Run the installer and follow its prompts, or extract the archive to a folder you control, such as a dedicated directory in your user profile. Keep the wallet in one predictable location so you always know where its data is stored and can back it up later.
-
Start the Program from a Terminal
Open Command Prompt or PowerShell, move to the folder that contains the wallet, and run it to confirm that it starts and lists its available commands. Only after this check should you create or restore a wallet and prepare to receive any Grin.
How to use Grin Wallet
Grin Wallet works through terminal commands, so the workflow is more deliberate than in a graphical app. The steps below describe the general flow rather than exact command syntax, which can change between releases. Check the documentation that ships with your version for the precise commands.
- Create a new wallet or restore an existing one, and write down the seed phrase on paper as soon as it is shown.
- Store the seed phrase offline in a secure place. Never type it into a website, a chat window or a form that claims to be support.
- Check your balance before you make any transfer, so you know exactly what you are sending.
- To receive Grin, share the address or transaction data your wallet produces with the sender through a channel you trust.
- To send Grin, enter the amount and recipient details carefully, then complete the exchange with the other party until the transaction is finished.
- Confirm the result by checking your balance again, and keep a simple log of transfers for your records.
- Back up the wallet data regularly, and test your recovery process with a small amount before you rely on it.
Pros & cons
- Free and open source, with no license fee to use the software
- Reference software from the Grin project itself
- Ready-made Windows build or installer available on the Releases page
- Source code is public on GitHub for anyone to review
- Lightweight terminal tool with no heavy graphical interface
- Command-line only, which can be intimidating for beginners
- Supports only Grin, so it is not a multi-coin wallet
- Requires careful manual backup of the seed phrase
- Less guidance for first-time users than graphical wallets offer
Is Grin Wallet safe?
Grin Wallet handles your private keys, so treat installation as a security decision. Download only from the official website or the official GitHub Releases page, and never from mirrors, forums or links shared in messages. Verify the SHA-256 checksum or signature before you run the file. Never enter your seed phrase on any third-party website, in a chat or in a form that claims to be support. Write the phrase on paper and store it offline. Antivirus software sometimes flags wallet programs, so if you see a warning, check the source of the file rather than disabling your protection. Check the latest version on the official website before you update.
- Official source only. Download from github.com/mimblewimble/grin-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
Grin Wallet differs from most programs in this category because it serves a single network. Coinomi, Exodus and Atomic Wallet are multi-coin wallets with graphical interfaces, and they suit people who hold many assets and prefer point-and-click controls. Electron Cash is also a focused, lightweight wallet, but it is built for Bitcoin Cash, which makes it a different network altogether.
Grin Wallet makes the most sense when Grin is the asset you care about and you want the project's own software rather than a general-purpose app. Frame and Trust Wallet take different approaches again, so choose based on the network and interface you need.

Frequently asked questions
Yes, Grin Wallet is free and open source. You do not pay a license fee to use the software, and its source code is public on GitHub for anyone to review. You can download the Windows build or installer at no cost from the project's Releases page.
Yes. The Grin project publishes a Windows build or installer on its GitHub Releases page, alongside builds for macOS and Linux. Choose the Windows file from the latest release, verify it, and run it from a terminal. Because the program has no graphical window, expect to work with typed commands.
It can be, if you follow careful habits. The software is open source, so its code is visible, and you can download it from the official GitHub Releases page, check its checksum, and keep your seed phrase offline. Many problems in this category come from fake downloads and phishing pages, so verify every file and every site you visit.
No. Grin Wallet is built for Grin only and does not manage other cryptocurrencies. If you hold several assets, you will need a separate multi-coin wallet for the others, such as Coinomi, Exodus or Atomic Wallet, and you should keep each one set up and backed up separately.
You do not need to write code, but you should be comfortable typing commands in a terminal. Ready-made Windows builds are available, so you do not have to compile the program yourself. Following the steps on this page carefully will help you avoid the most common setup mistakes.
A seed phrase is a list of words that lets you recover your wallet and the funds in it. Anyone who has the phrase can restore the wallet on another device, so it should never be shared or typed into a website. Write it on paper, store it in a secure place, and test recovery with a small amount first.
Yes, the project's code is published on GitHub, and the latest release is v5.5.1. Look at the repository's recent activity before you install, because update timing can change over time. Reviewing the Releases page is the simplest way to see which version is current.
Verdict
Grin Wallet is the right pick for people who want the reference software for Grin on Windows and are comfortable with a command-line tool. It is free, open source and focused on a single network, which keeps it simple to understand. If you need a graphical interface or several coins in one place, look at Coinomi, Exodus or Atomic Wallet instead. Practice with a small amount before you commit larger funds, and make sure your seed phrase is safely backed up.
