Update Roundup: Lattice1 Firmware v0.10.3 Released, New Web Wallet and MetaMask Features

GridPlus Lattice1 firmware v0.10.3 was just pushed to all devices over-the-air and includes improvements and features requested by our community. Your Lattice will automatically prompt you to update in the next few hours, but if you don’t want to wait you can navigate to the Settings menu then select Software Update to check manually.

Related changes have also been pushed through to the GridPlus Web Wallet and MetaMask fork as well.

With Lattice1 updates there’s no need to re-enter your seed phrase, simply tap the touchscreen prompt to approve the update and once your device automatically reboots you’re ready to go.

Key Features in V0.10.3

Here are a few of the key improvements you’ll see notice in the new release:

The maximum number of direct device and application pairings has been increased to 64.
The ABI parser has been updated to support ABI_V2, which was released in December 2020. Additionally, more function types have been added for broader support of modern smart contracts. Remember that Lattice users can “load” ABI definitions to allow more readable Ethereum transaction requests.
Allows you to set your own “25th word” password to a seed phrase generated by the Lattice. Previously this was only allowed when restoring a wallet from a seed phrase.
Various smaller bug fixes and UX improvements such as adding a cancel button to the pairing screen. There is a full list of changes for this release at the end of the post and you can also view the complete Lattice1 firmware changelog on GitHub.

GridPlus Web Wallet Updates

The GridPlus Web Wallet has been steadily evolving since launch: this past week more accurate Ethereum and Bitcoin transaction fee estimation was added and today we deployed the first batch of one click ABI contract installations. This allows you to clearly read signing requests on your secure screen.

The capability to do this was introduced in Firmware v0.10.1 in January, but the process was very manual. Now all users need to do is click install to load contract data for their favorite apps. We’re beginning by posting just a handful but will continue adding individual installs and packs.

This is an intermediate step in the evolution of our ABI parser. To learn more about this feature and where it is headed next check out this blog post from Alex Miller that explores it in depth.

There are also several UI improvements including a faster pairing secret screen.

GridPlus MetaMask Extension

This past week we rolled out a new version of the GridPlus MetaMask extension with a hotly requested feature: full access to all of your Lattice1 and SafeCard addresses. Previously the root address of each keypair was available to connect during the MetaMask pairing process, but now you can select any one you’d like from the HD path.

Full HD Address Path Access in MetaMask

The open-source GridPlus MetaMask fork is available for Chrome and Brave, but we have also received some requests for a Firefox build. So we put together exactly that! We have not encountered any issues in testing so far and will be publishing it soon.
