GridPlus Lattice1 Wallet Review

The Lattice1 is a large hardware wallet by GridPlus that looks and functions similarly to a point-of-sale terminal and backs up user cryptocurrency accounts on cards that look like bank cards.

In this review, I’ll cover my personal experience with the Lattice1, including its setup process, features, and more.

GridPlus Lattice1 Wallet Review Summary

The GridPlus Lattice1 is a large hardware wallet that stores cryptocurrency account backups on bank card-style chip cards.

It’s one of the most expensive hardware wallets on the market and may be best suited for those who need a large screen and/or make large volumes of transactions across several accounts.

1. What is a Hardware Wallet?

A hardware wallet is a type of crypto wallet that allows users to keep their assets in “cold storage.”

This means that the private keys are stored completely offline, without any connection to the internet.

Cold storage ensures that your private keys or seed phrases are secure for long-term safekeeping and cannot be remotely accessed under any circumstances.

2. Company Overview

GridPlus is a hardware wallet company that was founded in 2017 by software engineer Alex Miller.

The company is based in Austin, Texas, in the United States, with a focus on enabling users to securely store their crypto – while also allowing active use of their assets.

The Lattice1 and accompanying SafeCards are GridPlus’ flagship products.

3. What’s in the Box?

The GridPlus Lattice1 comes in a large, sleek, cube-shaped box that opens very smoothly, somewhat reminiscent of an Apple product.

Inside, you’ll find one Lattice1 hardware wallet, one SafeCard, a US 2-prong (type A) power supply, and an ethernet cable. On the SafeCard packaging, you’ll also find some simple directions for setting things up and a QR code and URL for a more comprehensive step-by-step guide.

I also ordered an additional two SafeCards, for additional accounts and/or back-ups.

4. Lattice1 Wallet Supported Coins

The Lattice1 directly supports Bitcoin and Ethereum, as well as a number of ETH Layer 2 protocols and forks like the Binance Smart Chain, Polygon, Avalanche, and others.

It also supports many ERC-20 tokens, like USDT, Chainlink (LINK), and others, as well as NFTs on the Ethereum mainnet, Polygon, and Immutable X.

In addition, all other Ethereum Virtual Machine (EVM) compatible chains are supported. More information can be found on GridPlus’ supported digital asset page.

The Lattice1 also integrates seamlessly with MetaMask, the highly popular Web3 wallet, as well as others. This enables users to connect to decentralized applications and use them while keeping their assets securely stored.

5. How Do I Setup My Lattice1 Wallet?

Step 1: Power on the Lattice1 and connect to the internet

Plug the Lattice1 device into the wall using the power supply included. The device will automatically power on and start up.

Connect to a WiFi network, or if preferred, connect to the internet using the ethernet cable provided.

Step 2: Set a passphrase and back up your seed phrase

Set up an optional passphrase, which will be used in addition to (not instead of) your seed phrase.

After this, your wallet’s seed phrase will be presented. Ensure that you write all 24 words down using a pen and paper or other reliable method. 

You will then be asked to confirm the seed phrase through the device.

Step 3: Back up your wallet using a SafeCard

Select “manage wallets” on the Lattice1 screen to initiate the SafeCard backup process. Tap on “Back up to SafeCard” and insert the new SafeCard provided with your device.

You will also be asked to create a PIN number for your SafeCard – this will be required whenever you use the SafeCard backup via the Lattice1 device.

6. Personal Usage Experience

As a self-standing unit with a large 5-inch screen, the Lattice1 was easy and enjoyable to use. I did expect the UI and screen to be a little more crisp, but it was a bit more basic than the price point may suggest.

The overall process was simple and smooth, and it was great not to have to plug anything into a computer. It would have been nice to have a battery pack in the device, but unfortunately, you must always keep it plugged into the wall while using it.

Another small detail that was missed was the opportunity to include a leaflet or lined paper for writing down your seed phrase – not the end of the world, but it would have been a helpful touch that most other hardware wallets include.

Aside from the above, the device felt very good quality, responded well, and was a breeze to use with the MetaMask integration. There were no hiccups with the SafeCard backup, which indicated that the device was sturdy and reliable.

7. How Much Does the Lattice1 Wallet Cost?

The GridPlus Lattice1 comes with a substantial price tag of $397 – much higher than almost any other hardware wallet device on the market.

Although it comes with its perks, it’s a lot of extra cost to justify the benefits. At this price point, I would only recommend the Lattice1 to those who are very high-volume Web3 users and/or those who plan to back up and consistently use several accounts.

8. Conclusion – Is the Lattice1 Wallet Worth It?

The Lattice1 is an excellent device for high-volume use with several accounts. The device has excellent build quality, a very easy-to-use large touch screen, and a very helpful MetaMask integration.

On the other hand, the device is extremely large compared to its peers, and although this makes it easy to view and use, it is not very portable. The device also comes with a very hefty price tag.

Overall, the Lattice1 is probably best suited toward a very specific niche of users that value security and being able to use many accounts, often and in one place.
