GridPlus
GridPlus is a brand of secure hardware wallets, like the Lattice1, that store private keys offline and enable air-gapped transaction signing for cryptocurrencies.
What Is a GridPlus?
A GridPlus is a brand of secure hardware wallets for cryptocurrency users. Devices like the Lattice1 (also called GridPlus Lattice) store private keys offline. They enable air-gapped transaction signing, keeping keys isolated from internet-connected devices.
GridPlus works by generating private keys inside a tamper-resistant secure element chip. Users access the device through a high-resolution touchscreen. To sign a transaction, connect it to an air-gapped computer or use QR codes for data transfer. The screen displays full transaction details for verification. It supports Ethereum Virtual Machine (EVM) chains, Bitcoin, and others without exposing keys.
GridPlus matters because it protects against remote hacks, phishing, and malware common in software wallets. Air-gapped signing ensures attackers cannot steal keys even if they compromise your computer. Users verify every detail on the secure hardware screen, reducing errors and fraud.
Key characteristics include open-source firmware for transparency, multisig support, and password protection. The Lattice1 features a 5-inch display and USB connectivity. GridPlus emphasizes user sovereignty and verifiable security.
Cryptocurrency is a digital or virtual currency secured by cryptography, operating on decentralized blockchain networks to enable secure, peer-to-peer transactions.

Example 1: Signing an Ethereum transaction air-gapped
A trader wants to swap tokens on Uniswap. They generate the unsigned transaction on their online computer. The computer displays a QR code. The user scans it with their GridPlus Lattice1. The device shows full details: recipient address, amount, gas fees. After verification, they approve signing on the touchscreen. The signed transaction QR code returns to the computer for broadcast.
Example 2: Setting up multisig for a business treasury
A small business sets up a 2-of-3 multisig wallet on Ethereum for ETH holdings. One key lives on a GridPlus Lattice1. To spend funds, two approvals are needed. An employee connects the GridPlus to an air-gapped machine, scans the transaction QR, verifies details on screen, and signs. This adds security layers against single-point failures.
Example 3: Verifying Bitcoin transactions securely
A Bitcoin holder receives a payment request. They prepare the transaction on Electrum wallet software on an offline computer. GridPlus Lattice1 imports the QR code. The 5-inch screen displays inputs, outputs, and fees clearly. The user confirms and signs without internet exposure, protecting against malware on their main PC.
