Thanks for posting, @Sandesh_Pokhrel! We have seen a lot of interest in ED25519 support, and it’s a no brainer that we’ll add support at some point. Some preliminary work has already happened in our libraries, but it has to do with MLS installation keys rather than wallet keys.
The multi-wallet work in XIP-46 is also a step towards this kind of thing.
In the short term, finishing up the Group Chat feature and getting our 1:1 chat moved over to the same MLS foundations will require everyone on our team. That said, we’re open source for a reason and we’d love to work with anyone willing to contribute time/ideas/effort to making this happen faster!
