I have been keeping an eye on 0x for a while now and have recently been considering an entry. However I have some questions I could not find answers to in existing resources:
1. How does 0x protocol work with rollups? Where is this on the roadmap?
2. Are there any special considerations around the implementation of 0x with sharding?
3. How is cross chain operability proposed to be implemented technically? Will 0x be collaborating with other active communities on this (such as Polkadot)?
Thanks in advance!
