Frostr is written in TS and is not focused on security first principles. Keep is built in Rust and is more similar to Amber than Frostr.
Keep's zapstore page doesn't explain anything about FROST. The github page elaborates a bit, but I shared the frostr page mainly because it does a great job explaining what it is all about. I love this concept and didn't event know it exists. Would be good to make it easily assimilated!
