GridPlus Lattice1 for Windows is the desktop software for the Lattice1 hardware wallet, built for people who want to manage Ethereum, other EVM-compatible assets and bitcoin while keeping their private keys on a dedicated device. It suits users who own or plan to buy Lattice1 and want to work with it from a Windows PC.
The software is proprietary and runs on your computer through the browser, so it fits alongside the wallet interfaces many people already use. Lattice1 is sold as a physical device, and the Windows version is the way to connect it to your computer. Read the installation and safety sections before you install anything or connect the device to a website.
What Is a Hardware Wallet and Why Use One?
A hardware wallet stores your private keys on a small dedicated device instead of on your computer. When an app needs a transaction signed, the request goes to the device, and the signature is created there. The computer never needs to see the raw keys.
This matters because a computer can be infected with malware, and an infected machine can read files, log keystrokes or show fake screens. With a hardware wallet, the attacker would still need the physical device and your confirmation to move funds.
The trade-off is cost and responsibility. You must buy the device, store it safely and keep your recovery phrase offline. Losing the recovery phrase can make funds unrecoverable, so the device is only one part of the setup.
Who Lattice1 for Windows Is Best For
The software suits people who already use Ethereum or EVM-compatible networks through MetaMask or Rabby and want a hardware layer for signing. A typical user connects the wallet in the browser, checks each request on the device, and approves only the transactions they meant to send.
It also fits people who value a larger screen for reviewing details. If you often sign messages or interact with several decentralized apps in a single session, a clear display can reduce mistakes.
It is less suited to anyone who wants only a simple app on a phone or who prefers a software-only setup without buying hardware.
How Browser Connections Work With a Hardware Device
When you connect a hardware wallet to a browser extension, the extension shows your account addresses and balances, while the private keys remain on the device. The extension prepares a transaction or message and sends it to the hardware for approval.
The browser window alone does not always show every detail of a request. That is why the screen on the device matters. Compare the recipient address, the network and the amount on the device before pressing confirm.
If a request on the device looks different from what the website promised, reject it. A mismatch is a reason to stop, not a reason to approve.
Key features
Large on-device screen
Connection to MetaMask and Rabby
Ethereum, EVM and bitcoin support
Supported coins
The Lattice1 setup covers ETH, EVM-compatible networks and BTC. Ethereum-based tokens on EVM networks are managed through the same browser connection, so you do not need a separate device for each network. Check the current list of supported networks before sending funds.
How to install GridPlus Lattice1 on Windows
- 1
Get the Windows software
Open the official website at gridplus.io and find the Windows download for the Lattice1 software. Avoid links from search ads, messages or social posts, even if they look official.
- 2
Verify the file
Compare the SHA-256 checksum or the digital signature of the downloaded file with the values published by the developer. If they do not match, delete the file and do not run it.
- 3
Run the installer
Start the installer and follow the on-screen prompts. Windows may ask for permission to make changes to your device. Accept only after the file has passed verification.
-
Set up the hardware device
Connect the Lattice1 device and follow its setup steps on the screen. Write your recovery phrase on paper and store it offline. Never type it into a computer, a website or an app.
How to use GridPlus Lattice1
Once the device is set up, the daily workflow is short. Allow a few minutes for the first connection, and check every request on the device screen.
- Open the GridPlus Lattice1 software on your Windows PC and unlock the hardware device.
- In MetaMask or Rabby, choose the option to connect a hardware wallet and follow the prompts.
- Confirm that the account shown on the device matches the account in your browser.
- When a site asks you to sign a transaction or message, read the recipient, network and amount on the device.
- Approve only what you intended, then wait for the network to confirm the transaction.
- Disconnect the device and close the software when you are finished.
Pros & cons
- Large screen for reviewing details on the hardware device
- Works with MetaMask and Rabby through a browser connection
- Covers ETH, EVM-compatible networks and BTC
- Official Windows version available
- Requires buying a physical device before use
- Day-to-day interface depends on browser wallets such as MetaMask and Rabby
- Proprietary software, so outside reviewers cannot inspect its source code
Is GridPlus Lattice1 safe?
Use only the official website at gridplus.io to get the Windows software, and check the SHA-256 checksum or digital signature before running the installer. Never enter your recovery phrase on a website, in a pop-up or in any app that asks for it, because no legitimate hardware wallet needs it typed into a computer.
A hardware wallet protects private keys, but phishing sites can still trick you into approving a malicious transaction. Read the details on the device screen every time. Because the software is proprietary, verifying the file before installation matters even more. Check the latest version on the official website before installing and keep your device software current.
- Official source only. Download from gridplus.io. 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
Lattice1 for Windows sits in the same category as Ledger Live, Trezor Suite and BitBoxApp. Each of those is a companion program for its manufacturer's own hardware, so the choice often depends on which device you want to buy. Lattice1 stands out for its large screen and its focus on connecting to MetaMask and Rabby through the browser.
Keystone also works with PC software through third-party wallets, so its workflow is somewhat similar. When comparing, look at which networks you need, how comfortable you are with browser-based signing and how you feel about proprietary software.

Frequently asked questions
It can be, as long as you download the software from the official website, verify the file before installing and keep your recovery phrase offline. The software connects to the device, and the private keys stay on the hardware. Most risk comes from phishing sites and fake downloads, so follow the safety steps each time.
Yes. The software is built to work with the Lattice1 hardware wallet, which is sold as a physical device. Without the device, the program has no keys to manage. Plan the purchase as part of your setup and buy from a seller you trust.
Yes. The software connects with MetaMask and Rabby through your browser, so you can keep using those interfaces while approving requests on the device. Check each transaction on the hardware screen before confirming, because the browser window does not always show every detail.
The wallet supports ETH, EVM-compatible networks and BTC. This lets you manage Ethereum-based assets and bitcoin with one hardware device. Confirm the current list of networks before sending funds, since supported networks can change over time.
Your main cost is the Lattice1 hardware device, which you must buy to use the software. Read the seller's terms for shipping, returns and warranty before ordering. Compare the device price with other hardware wallets if budget is a concern.
No. Ledger Live is the companion app for Ledger devices, while Lattice1 is GridPlus's own hardware wallet and its Windows software. Both are used to manage keys on a dedicated device, but they are not interchangeable and work with different hardware.
Verdict
GridPlus Lattice1 for Windows suits people who already use MetaMask or Rabby and want a hardware device with a large screen to review transactions. It is a practical option for holders of Ethereum, EVM-compatible assets and bitcoin who accept buying dedicated hardware. It is less suited to anyone who needs open-source software they can inspect or who prefers to avoid browser-based workflows. Compare it with other hardware options before buying, and check the latest version on the official website.
