Gave it a quick read, will go back through it tomorrow also. This API caught my eye:

public void Sign(ReadOnlyMemory<byte> message, Memory<byte> signature)

Do you think it would be more natural to instead have it return the signature?

public Memory<byte> Sign(ReadOnlyMemory<byte> message)

the intention is to avoid memory allocations or at least give the opportunity to do so. in the future if we can update the underlying ed25519 functions we can also introduce Span versions as well.

Makes sense, we could add more user-friendly extensions that allocate in the future if people seem to want them
