I'm facing my first sawtooth app and I'm not sure how you are supposed to handle the user's keys to sign transactions locally. The client is going to be a web app.
I was wondering if there is something like metamask for sawtooth, or even if metamask would be officially compatible with sawtooth. I've checked this question and it seems to work, but with low level changes that make me wonder if that will work for long.
What is the recommended way to do this?
