That's good news, thanks! Do you know how many resident keys you're going to end up storing? I'm really suffering with the Yubikey's 25, I'm going to write a post on SSH auth with FIDO2 and would like to be able to recommend SoloKeys.

With the current Solo we have 256kB of flash so we sort of arbitrarily reserved space for 50 RKs, but you can prob tweak the firmware if you need.

With the next gen of Solo we have 2MB of flash, so assume virtually unlimited RKs, at least given the number of sites that currently support them.

(note: double checking w/ the team for correctness)

That's really exciting, thanks. I'm kind of banking on FIDO2 RK becoming the standard on the web, so I really want a key that can support thousands of sites. I might be customizing the firmware (AFAIK it's in Rust), and I'm really hoping I can get one of the preview devices to help testing.
