It doesn't, at least not for generic/unmodified cryptographic applications.
WebAuthN signatures are of a very specific challenge/response format [1] that applications need to explicitly support. For example, SSH had to add new key and signature formats [2] to support it.
Theoretically, a blockchain/cryptocurrency application could adopt the WebAuthN signature format as its canonical or an alternative signature format, but I'm not aware of any popular one having done so.
