Our impressions

GridPlus Lattice1

Coldcard Mk4

Pros
  • Very high usability through the 5-inch touch-screen
  • Does not require USB connection
  • Uses theย BIP-39 standard, which allows wallet recovery even without hardware
  • Open source software that can be audited by the community
  • Supports SSH access to control the Linux environment of the device (ideal for advanced users / tinkerers)

Cons
  • Not very portable (yet… there are hints from the GridPlus team that they might work on a portable version that supports SmartCards)
  • Supports only one non-mainstream wallet app on smartphones
  • Requires it’s own power supply and Internet connection (supports Ethernet and WLAN)

Verdict

The GridPlus Lattice1 features a very unique SmartCard concept. The base station stays on your desktop and you just carry your wallet on a SmartCard that has the same dimensions like any other credit card. In our mind this seems like the perfect setup in professional workplace environments. The 5-inch touch screen will also appeal to private users, as it really makes interactions much more comfortable in comparison to other hardware wallet products.

Support of Ethereum and EVM based chains is very good, especially on Desktop PCs and Notebooks on Windows, MacOS, and Linux. Smartphone support is a bit lacking as there are not yet a lot of apps to choose from. Bitcoin support is limited to the Lattice Manager application, which does support sending and receiving BTC. Also portability might be an issue, if you do not own multiple devices. It seems like the GridPlus is already working on a product addressing this though.

In conclusion: In terms of security the device features many thought-through anti-tempering and security features. Integration into the Ethereum / EVM ecosystem is very mature and offers a very high level of usability. Depending on your use-case this might be the perfect form factor for you.
