Hi there, I am developing Minibits wallet. Thank you for trying it. As of now, there is not yet fully functional recovery path ready for cashu tokens, however the protocol that would allow recovery of lost tokens is designed and on the roadmap. In the meantime, there is basic append only backup of all wallet tokens in a separate on device sqlite database, intended mostly to recover in case the wallet state becomes bricked due to some wallet or mint error. Until proper recovery processe are in place, wallet will remain beta and I recommend to use it with small amounts or with your own mint. Will you encounter issues, please raise them on github, there is still a lot to do.
