Who it suits

  • Long term holders who want their keys offline
  • Anyone who prefers handling the device themselves
  • Savers planning for a multi coin setup

The company behind it

The Lattice1 comes from GridPlus Inc., which is based in the United States. The device is a hardware wallet with self custody, so the company builds the product rather than holding your coins. Questions go through email, help centre and community, which means written replies and self service materials rather than a phone line.

Frequently asked questions

How much does the GridPlus Lattice1 cost?+

The device is sold at a hardware price of $397. That is a one off cost for the hardware itself, and no subscription or account charge is stated. Buyers weighing a cheaper route can look at Trezor, priced at $79.

Who holds my coins?+

You do. Custody is self custody, so the keys sit with the owner rather than with a company account. The company builds and supports the device, but it does not take control of holdings.

What secures the keys on the device?+

Keys are protected in bank vault chips, which is the kind of chip used for bank vaults. That places the secret material in dedicated hardware rather than in general purpose memory.

How do I recover a wallet if the device fails?+

Recovery runs through seed. A seed backup means the recovery material is yours to store, and it is a single secret rather than a split set of shares. Losing that seed means losing access, so storage matters.

What kind of wallet is it?+

It is a hardware wallet, so coins are moved by signing on the device rather than in an app. That suits holding, and it adds a physical step compared with a mobile wallet from eToro.

How do I get help from the company?+

Support runs on email, help centre and community, so questions are handled by email, a help centre and a community. There is no phone number or live chat in the channels listed, which matters if a device fails while funds are held.

Is GridPlus Lattice1 regulated?+

No regulator is listed for the product, which is consistent with a self custody device rather than a custodial platform. The company behind it is GridPlus Inc. in the United States. Protection schemes apply to accounts held by firms, not to keys you control yourself.
