  • Users verify smart-contract and transaction details on the 5-inch secure touchscreen before approval
  • Users properly back up Lattice wallets to SafeCards or seed phrases
  • WiFi/Ethernet connected general compute environment may be compromised without exposing private keys, as assumed by the security model

Known Issues

2026: Secure appliance versus portable wallet tradeoff

Lattice1 is closer to a desk-based secure signing terminal than a pocket hardware wallet, which improves transaction readability but limits portability and mainstream appeal.

2026: Proprietary high-security architecture

GridPlus documents a sophisticated separated-compute architecture, but users must trust proprietary firmware and hardware implementation rather than independently reproducible open-source builds.
