here you can see how I'm using Shamir Secret Sharing, I gave clear instructions on how to use the shares and in what circumstances.

based on their dynamics, I'm feeling pretty good. I know I have some people there that are tech savvy + some that will take good care of their shares and when they should send those to whom.

Implementation is trivial (especially if you find a library) but maybe you can be inspired by my plan https://g3rv4.com/2022/04/a-plan-for-my-secrets
