What it does
GridPlus provides the Lattice1 hardware wallet and PIN-protected SafeCards for managing several wallet key sets. The USD 397 device includes one SafeCard; a pack of two extra cards costs USD 40. Its five-inch screen handles transaction review, while Wi-Fi or Ethernet supplies network access.
Removable SafeCards provide a physical way to organize wallets without buying a separate display device for every key set. A card holds the selected key material, and Lattice1 presents the transaction for review and approval. The device is network-connected, so it should not be confused with a signer that operates entirely offline.
Set up the device and card separately
Connect power, choose Setup and select 2.4 GHz Wi-Fi or Ethernet. Set a four-to-six-digit system PIN, configure the anti-tamper mesh and choose Generate Wallet or Restore from Seed Phrase. A newly generated wallet has 24 recovery words and can use an optional passphrase.
A SafeCard has its own six-digit PIN. Insert a new card into the unlocked Lattice1 to create a wallet or restore one from a supported phrase. Keep an independent backup: the card should not be the only surviving copy, and the device's tamper response can erase its wallet.
Pair an application
In Lattice Manager, enter the Device ID shown on the hardware and choose a password, then select Connect. Confirm the pairing secret on the device. This creates an application permission without an email-registration step. The manager can give addresses recognizable tags that also appear on the hardware display.
Bitcoin and Ethereum-compatible workflows use different companion applications. The current documentation points Bitcoin users toward NuFi and warns that Lattice Manager's own Bitcoin wallet may be retired, so older instructions calling it the only Bitcoin interface are no longer reliable.
The supplied power adapter uses a Type A plug. Purchases ship from the US; import duties and destination restrictions need to be checked for the delivery country.
