Our verdict
GridPlus Lattice1 is a hardware wallet for long-term holders who put device security ahead of price. Keys stay in self custody with the holder and signing runs on bank vault chips, and the $397 device is a one-off purchase with no account to manage.

Pros and cons
Pros
- bank vault chips keep transaction signing on the device
- Self-custody with a seed backup puts keys with the holder
- Hardware form factor at $397 suits cold storage of larger holdings
Cons
- The device costs $397, far above the €69.28 typical for hardware wallets
- Backups use a seed, so a single written record guards the whole holding
- Support runs on email, help centre and community only
Who it suits
- Long-term holders storing coins on the device itself
- Anyone who puts bank vault chips ahead of a low price
Who should look elsewhere
- Buyers on a tight budget, who would find Trezor far cheaper at $79
- People wanting a phone app, since Bit2Me is a mobile wallet
- Users who prefer a provider holding the keys, since bynex is custodial
The company behind it
The Lattice1 is made by GridPlus Inc., registered in the US. It is a hardware device, so the buying decision rests on one box you own rather than an account balance elsewhere. Support comes through email, help centre and community, which keeps answers in writing and in the company's own materials. Anyone weighing GridPlus against a cheaper device is really comparing security design and the cost of the hardware itself.

Frequently asked questions
How much does the GridPlus Lattice1 cost?+
The device is priced at $397 as a one-off purchase. That is a far bigger outlay than the €69.28 typical of hardware wallets, so the budget matters as much as the security design. There is no ongoing account fee attached to the hardware itself.
Who holds the coins on the Lattice1?+
Keys stay with the holder, and the device works in self custody. Nothing sits with a provider on your behalf, so there is no third party to ask if a seed is lost. You also cannot lean on a provider's support team to restore access, because recovery starts with your own backup.
What happens if I lose the device?+
Recovery rests on the seed you wrote down at setup. That is the same approach most hardware wallets take, and it means a lost device is survivable only if that record is kept somewhere safe. Losing both the device and the seed record ends the holding.
How is the device secured against tampering?+
Transaction signing happens through bank vault chips, the same bank vault chips used in payment hardware. The chips are designed to resist physical attack on the device itself. Self-custody through self custody means the signing step stays on your unit rather than on a server.
What support can I get from GridPlus?+
Support runs on email, help centre and community, so help is written and self-serve rather than spoken. No voice channel is listed for hardware questions, which suits holders comfortable reading documentation before touching a device that holds self custody keys.
Who is the Lattice1 built for?+
The device targets holders keeping coins on the box itself rather than making everyday payments. self custody suits long-term holding, since the owner keeps the keys. Buyers wanting phone-based access would be better served by a mobile wallet such as Bit2Me.
Who is behind GridPlus?+
The device comes from GridPlus Inc., based in the US. It sells hardware rather than holding customer balances, so the self custody side of things sits with the buyer. Terms and policies are published by the same company.
Should I choose this over a cheaper hardware wallet?+
Compare what the extra money buys: $397 against $79 for Trezor. The Lattice1 adds bank vault chips to a device that already keeps self custody. If a lower price matters more, Trezor is the cheaper route to the same self-custody model.
