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.
