Alternatives to GridPlus Lattice1
Hardware wallet with secure enclave and SafeCards
GridPlus Lattice1 ranks #11 of 12 in Hardware wallets, with an Alt Score of 59. It is proprietary, sold as a one-time purchase from $397 USD and available on Web and Browser extension. 12 of 12 checklist rows are verified against a public source.
Active crypto users, DeFi/NFT traders, and self-custody holders who want a large-screen, always-connected hardware wallet that plugs directly into MetaMask, Rabby, or other software wallets rather than a small offline USB dongle.
A $397 touchscreen hardware wallet (the Lattice1, includes one free SafeCard) with a dedicated Secure Enclave chip, tamper-mesh enclosure, a 5-inch screen for readable transaction review, and unlimited hot-swappable SafeCard wallets, connected over WiFi/Ethernet rather than USB or Bluetooth.
The Lattice1 splits into two isolated compute environments — an internet-connected General Compute Environment and an offline Secure Compute Environment holding your private keys — so signing requests travel over WiFi/Ethernet to the device, are shown in full on the touchscreen for approval, and are signed either by the built-in Secure Enclave or an inserted, PIN-protected SafeCard before being relayed back to apps like MetaMask.

Multisig support Partial verified 2026-07-12
No native on-device multisig/Shamir feature; multisig is achieved by using the Lattice1 as a signer within a third-party smart-contract multisig (e.g. Safe).
Right now, the Lattice does not support Shamir, but you can substitute it with using an Ethereum multisig service such as the Safe account abstraction stack.
