GridPlus

GridPlus is a hardware wallet company focused on secure cryptocurrency storage and transaction signing. Its core product, the Lattice1, is a desktop terminal with a 5-inch touchscreen. Unlike traditional hardware wallets with small screens and buttons, the Lattice1 uses a dual-environment architecture: a General Compute Environment (GCE) for connectivity and a Secure Compute Environment (SCE) that isolates private keys. The SCE is protected by a tamper-detection mesh and requires physical confirmation for each transaction. Keys are backed up on removable SafeCards, which replace paper seed phrases. The device supports Bitcoin, Ethereum, and all EVM-compatible chains, and integrates with wallets like MetaMask and Rabby.

The market pain point GridPlus addresses is the trade-off between security and usability in self-custody. Traditional hardware wallets are secure but have poor user interfaces, making transaction verification error-prone. The Lattice1 solves this with a large screen and clear transaction previews, reducing the risk of signing malicious data. Its always-on design and network connectivity (WiFi/Ethernet) enable direct dApp interaction, which is more convenient than USB-based workflows.

In the past six months (Feb-Aug 2026), GridPlus has focused on firmware stability and expanding wallet integrations. The company released updates improving the SafeCard backup process and enhancing the SCE's resistance to side-channel attacks. They also launched a public bug bounty program to encourage security research, with rewards based on vulnerability impact. However, in late 2025, a security researcher demonstrated a potential firmware exploit that required physical device access; the issue was patched in a subsequent update. No critical vulnerabilities have been publicly reported since. The company continues to emphasize that the Lattice1 is not portable and requires AC power, which limits its use case to stationary setups.
