Thanks for your submission! Can you confirm that Lattice1 meets all of the requirements listed here? In particular,

• Provides source code created for all open components and provides detailed specification for blackbox testing of any closed-source secure elements

A brief review of the web site seemed to suggest Lattice1 was closed-source.

As the wallet seems to be closed source and there has been to response related to that issue for over a year, let's close this until we receive new information to the contrary.
